ENCYCLOPEDIA OF HEALTHY SLEEP ONSEN®

Don't know what to look for when choosing an orthopedic mattress or pillow? Do you not understand the markings of polyurethane foams types used by mattress manufacturers? Are you looking for reliable knowledge on topics related to healthy sleep and comfort at night? Welcome to the glossary that defines the most important topics in technology, health and other topics related to sleep!

ADRENALINE

Adrenaline, also known as epinephrine, is a hormone produced by the adrenal glands. It plays a major role in stressful situations that require strong nervous stimulation, hence it is also called the hormone of fear, fight, and flight. Increased levels of adrenaline have a negative impact on the quality of sleep.

ADRENOCORTICOTROPIC HORMONE (ACTH)

Adrenocorticotropic hormone, also known as ACTH, is a hormone produced by the pituitary gland. It plays a major role in stimulating the production of cortisol, acting on the principle of negative feedback. A decrease in the level of adrenocorticotropic hormone in the blood negatively affects the quality of sleep.

ACUPRESSURE

Acupressure is a therapeutic method originating from China, which has been successfully used for several thousand years. It is based on applying pressure with fingers to specific points on the body to achieve a therapeutic effect. It should only be performed by specialists and in consultation with a doctor. Maintaining its effects helps to achieve comfortable sleep in a natural, physiological position.

ACUPUNCTURE

Acupuncture is a therapeutic method originating from China, which has been successfully used for several thousand years. It is based on stimulating specific areas of the skin using thin needles to achieve a therapeutic effect. It should only be performed by specialists and in consultation with a doctor. Maintaining its effects helps to achieve comfortable sleep in a natural, physiological position.

ALLERGY

Allergy, also called sensitization, is a tissue response to the action of allergens, which is qualitatively different from the physiological response. It is associated with an immune reaction that involves the release of IgE antibodies leading to the production of inflammatory mediators. In the case of allergies, great attention should be paid to the anti-allergic (hypoallergenic) properties of mattresses, pillows, and bedding.

ALOE

Aloe is a succulent houseplant. In addition, aloe is one of the plants that purify the air. It does an excellent job of absorbing volatile organic compounds, carbon monoxide, benzopyrene, and lead. Aloe also has the ability to purify the air from ammonia, benzene, xylene, toluene, trichloroethylene, and formaldehyde.

ANATOMY

Anatomy is the science that deals with the study of the structure of organisms. It is a branch of biology that investigates the location, shape, composition, and evolution of organs, as well as tissues and cells. Therefore, it remains crucial for the production of orthopedic mattresses and pillows.

ANHEDONIA

Anhedonia is the inability to experience pleasure and joy in various aspects of life. It can occur in the physical, emotional, or intellectual realm and may occur independently or together. Anhedonia is often a prominent symptom in diagnosing various mental illnesses, particularly mood disorders such as depression. Sleep in a state of anhedonia typically does not provide restful or rejuvenating effects, regardless of its duration.

ANTHURIUM

Anthurium is a houseplant from the family of Araceae. Additionally, anthurium is one of the plants that purify the air. It performs excellently in absorbing volatile organic compounds, carbon monoxide, benzopyrene, and lead. Anthurium also shows the ability to purify the air from ammonia, benzene, xylene, toluene, trichloroethylene, and formaldehyde.

ARTHROSCOPY

Arthroscopy is a surgical procedure that involves using an arthroscope to inspect the interior of joints. It can be a diagnostic arthroscopy that aims solely to examine the joint from the inside to determine its condition. However, it is most commonly a therapeutic arthroscopy in which surgery is performed using miniature surgical instruments. After arthroscopy, attention should be paid to sleeping in a physiological position, which will not only play a role in rehabilitation and treatment but also prevent the recurrence of conditions that are the cause of it, for which an orthopedic mattress is used.

BALNEOTHERAPY

Balneotherapy is one of the branches of physiotherapy. In balneotherapy, the therapeutic properties of mineral waters are used. The therapeutic procedures in balneotherapy mainly include baths and inhalations.

COTTON

Cotton is a natural fiber used to produce soft fabrics and wound dressings. Cotton is commonly used for bedding production and as elements in pillows and mattresses. Although cotton is popular and considered healthy, its use is increasingly being questioned. The porous structure of cotton provides an excellent habitat for microorganisms and maintains moisture. Additionally, cotton fibers are not very elastic, which affects its low resistance. It is also often said that glyphosate, a substance that increases the risk of cancer, hormonal disorders, autism, Alzheimer's disease, or Parkinson's disease, is used on most cotton plantations.

BUFFALO HUMP

Buffalo hump is also called the widow's hump or widow's peak. It is a characteristic bulge on the back, specifically at the junction of the cervical spine and thoracic spine. However, it is not a hump on the back caused by spinal disorders, but a combination of connective tissue and adipose tissue. It usually has a hormonal basis, and is particularly common in the course of Cushing's syndrome. If you have a buffalo hump, it is important to pay attention to sleeping in a physiological position, which will not only play a role in rehabilitation and treatment but also prevent relapses of the conditions that cause it, for which a pillow for buffalo hump is useful.

BEGONIA

Begonia is a houseplant from the family of begoniaceae. Begonia is also one of the plants that purify the air. It is excellent at absorbing volatile organic compounds, carbon monoxide, benzo[a]pyrene, or lead. Begonia also has the ability to purify the air from ammonia, benzene, xylene, toluene, trichloroethylene, or formaldehyde.

SLEEP APNEA

Sleep apnea is a condition that involves repeated episodes of complete or partial blockage of the airway during sleep, resulting in increased frequency of respiratory muscle movement. It occurs in the form of central sleep apnea, which involves complete cessation of breathing, as well as obstructive sleep apnea, which occurs in cases of partial blockage of the airway. In extreme cases, it can be a life-threatening condition. The use of a sleep apnea pillow can be helpful in preventing and treating the condition, allowing for the maintenance of a physiological position of the cervical spine during sleep.

SLEEPLESSNESS

Sleeplessness, also known as insomnia, is a sleep disorder that is becoming increasingly common. It is characterized by difficulties in falling asleep, staying asleep, and/or waking up too early. The criterion for diagnosing insomnia also includes its impact on daytime functioning. Poor sleep hygiene can contribute to the occurrence of insomnia.

BIOHACKING

Biohacking is a lifestyle that assumes that by introducing certain changes to one's way of life, we can maximize our biopsychosocial capabilities. In other words, biohacking is intended to increase human physical and mental performance, as well as social competence. There are many methods for implementing the principles of biohacking, which are very well described by Biohaker, one of the most popular bloggers in Poland.

IVY

Ivy is a houseplant from the Araliaceae family. Additionally, ivy is one of the plants that purify the air. It is excellent at absorbing volatile organic compounds, carbon monoxide, benzo[a]pyrene, and lead. Ivy also has the ability to purify the air of ammonia, benzene, xylene, toluene, trichloroethylene, and formaldehyde.

BRADYCARDIA

Bradycardia refers to a condition in which the heart beats slower than 60 times per minute, or beats too slowly. Although sometimes it is a physiological state, the causes of bradycardia should be diagnosed with the help of a doctor.

BRUXISM

Bruxism is the unconscious clenching and grinding of teeth. Although it also occurs during the day, bruxism most commonly occurs at night. Its consequence is primarily the wear and tear of teeth, which also leads to their cracking and loosening. It also leads to changes in the temporomandibular joints. Maintaining proper sleep hygiene and reducing nervous tension are important in its prevention and treatment.

ALARM CLOCK

Alarm clock is a clock designed to emit a sound at a specific time. It comes in both traditional mechanical forms and electronic forms. Intelligent alarm clocks are becoming more common, which allow for proper sleep hygiene.

BULGING

Bulging is the first stage of intervertebral disc damage. It occurs in the course of discopathy and involves the protrusion of the intervertebral disc due to the displacement of the nucleus pulposus beyond its natural location. Most often, bulging does not yet cause pain.

PRICE

Price should be the monetary expression of the value of a given product. Its task is to express the value of a given product or service in money. When buying a mattress or an orthopedic pillow, the price is of secondary importance, as most manufacturers and sellers artificially inflate it.

SNORING

Snoring is a sound that we make when the walls of the throat vibrate due to the air flowing through them. It is most often related to the inability of the person snoring to breathe freely through their airways. Its treatment should therefore be fully causal. Snoring always negatively affects the quality of the snorer's sleep, as well as the people nearby. In its prevention and treatment, it is worth taking care of the proper pillow for snoring.

CIESIELSKI

Ciesielski is one of the popular Polish surnames. According to data from 2022, as many as 15,931 men currently bear it. It is also the surname of Jacek Ciesielski, a sleep expert, thanks to whom the ONSEN® brand was created, which produces the best products for comfortable, healthy sleep.

BLOOD PRESSURE

Blood pressure is a term used to describe the force of pressure that the flowing blood exerts on the walls of the arteries. It is not constant and varies depending on the rhythm of the heart, as well as the functioning of the circulatory system. When measuring blood pressure, two values are determined: systolic (maximum) and diastolic (minimum) pressure. It is important for blood pressure to be close to normal during sleep, as this is essential for maintaining the proper functioning of the organs. It therefore affects the effectiveness of sleep and the regenerative abilities of the body.

PRESSURE HEADACHE

Pressure headache is a type of headache that occurs due to changes in atmospheric pressure. It often has no specific cause or duration. Its frequent occurrence should be consulted with a doctor. Pressure headache often manifests as a migraine, as well as a headache upon waking up.

COSLEEPING

Cosleeping is the practice of sleeping more than two people in one bed. It most often refers to parents sleeping with their child, or even the whole family sleeping together. In the past, cosleeping was a necessity to increase children's chances of survival. Today, cosleeping is gaining popularity mainly for practical reasons, which has gained both supporters and opponents.

DIABETES

Diabetes is a metabolic disease characterized by elevated levels of glucose in the blood, which is called hyperglycemia. It is divided into two types, namely:
  • insulin-dependent diabetes (type 1 diabetes) in which the beta cells of the pancreas are damaged, resulting in a primary lack of proper insulin production;
  • insulin-independent diabetes (type 2 diabetes) in which there may be a disorder of insulin secretion by beta cells of the pancreas, as well as improper insulin action and insulin resistance.

CYCLOTHYMIA

Cyclothymia is a mood disorder characterized by alternating episodes of depression and mania, but in a milder form than in bipolar disorder. To diagnose cyclothymia, its symptoms must persist for at least 23 months. Only a psychiatrist can make a diagnosis of cyclothymia. Its occurrence negatively affects the quality of sleep and its proper structure.

AIR CIRCULATION

Air circulation is a phenomenon that involves the movement of air within a closed system. Proper air circulation ensures that the air is always fresh. Adequate air circulation in a mattress and pillow allows for comfortable and healthy sleep. It helps to limit body overheating and sweating during sleep while also allowing for the removal of microorganisms.

DEPRESSION

Depression is an affective (mood) disorder whose symptoms are mainly based on anhedonia, low mood, loss of interest, decreased concentration, and attention. To diagnose depression, its symptoms must persist for at least 2 weeks. Only a psychiatrist can diagnose depression. Its occurrence negatively affects the quality of sleep and its proper structure.

DESIGN THINKING

Design thinking is a design method focused on users and their needs. It is based on five steps: empathy, definition, ideation, prototyping, and testing. Implementation follows these steps. Thanks to design thinking, ONSEN® products are the best on the Polish market.

DIAGNOSTICS

Diagnostics is the process of recognizing a given phenomenon based on objective data and identifying the sources of existing difficulties. The term "diagnostics" is most commonly used in medicine, psychology, and physiotherapy, where it means the diagnosis of disorders or diseases based on the results of conducted tests.

DIAGNOSIS

Diagnosis is an assessment of a given state of affairs based on the conducted diagnosis. The term "diagnosis" is most commonly used in medicine, psychology, and physiotherapy, where it means the recognition and classification of a given disorder or disease.

WHY?

WHY? is the question we ask ourselves at ONSEN® before creating each of our products. It is crucial for the functionality of our products, which must serve a purpose. Thanks to this idea, which we adopted from its creator, Simon Sinek, we stand out from the competition and offer the best products.

DOPAMINE

Dopamine is a hormone produced by nerve cells in the brain and spinal cord. It plays a significant role as a natural motivator of the body, and is also known as the reward hormone. It also affects memory and concentration, as well as maintaining relationships between partners. Its high concentration stimulates the body to act, which strongly disrupts sleep.

DRACAENA

Dracaena is an indoor plant from the asparagus family. Moreover, dracaena is one of the plants that purify the air. It is excellent at absorbing volatile organic compounds, carbon monoxide, benzopyrene, and lead. Dracaena also has the ability to purify the air of ammonia, benzene, xylene, toluene, trichloroethylene, and formaldehyde.

NAP

Nap is a short sleep during the day, less commonly at night. Typically, a nap lasts no more than a few dozen minutes. By definition, a nap lasts less than 50% of the time of a full night's sleep.

DYNAMICS

Dynamics is the resultant force, energy, and speed with which phenomena change. In mattresses, dynamics refer to the behavior of the materials used in them under the influence of the human body, which is influenced by their hardness and density.

DYSFUNCTION

Dysfunction means the inability of something to perform specific functions. The term "dysfunction" is most commonly used in medicine, psychology, and physiotherapy, where it means the abnormal functioning of a given organ, tissue, or cell.

DISCOPATHY

Discopathy is a degeneration of the intervertebral disc, commonly known as a disc. It is one of the most common spinal disorders.

DYSTHYMIA

Dysthymia is a mood disorder whose symptoms are similar to depression, but it lasts significantly longer. To diagnose dysthymia, a persistently low mood for at least 2 years is required. Only a psychiatrist can make a diagnosis of dysthymia. Its occurrence negatively affects the quality of sleep and its proper structure.

EXPERT

Expert is a person who possesses specialized knowledge in a particular field or fields. For this reason, an expert is often an authority in specific categories of knowledge. Therefore, it is important to buy mattresses and pillows only from companies that collaborate exclusively with experts and not salespeople.

EXTRUSION

Extrusion is the third degree of advanced damage to the intervertebral disc. It occurs in the course of discopathy and involves damaging most of the fibrous rings, as well as pressing on the spinal canal and spinal nerves. Extrusion often causes severe pain and difficulties with movement.

ELASTICITY

Elasticity is the ability of a material to temporarily deform and quickly return to its original shape. Thanks to the elasticity of polyurethane foam contained in a mattress, it can provide not only comfort but also increase the product's lifespan.

ELECTROENCEPHALOGRAPHY

Electroencephalography, also known as EEG, is a test that measures the electrical activity of the brain using an electroencephalograph. It allows the evaluation of brain function with a specific focus on the areas of analyzed activity. During an EEG, electrodes attached to the scalp record the electrical impulses transmitted between neurons. Electroencephalography is used during a polysomnographic study to observe the activity of specific waves during specific stages of sleep.

ELECTROCARDIOGRAPHY

Electrocardiography, also known as EKG, is a test that measures the electrical activity of the heart using an electrocardiograph. It allows the evaluation of the heart's function with a specific focus on the analyzed activity of its parts. During an EKG, electrodes attached to the chest and limbs record the electrical impulses associated with the heart's function. Electrocardiography is used during a polysomnographic study to exclude any abnormalities in heart rhythm during sleep.

ELECTROMYOGRAPHY

Electromyography, also known as EMG, is a test that measures muscle activity using an electromyograph. It allows for the evaluation of muscle contractions that occur after stimulation of nerves with electrical impulses. During electromyography, a specific nerve is stimulated using a needle electrode or all nerves are stimulated using electrodes attached to the skin. Electromyography is used in polysomnographic studies to examine muscle tension during specific stages of sleep.

ELECTROOCULOGRAPHY

Electrooculography, also known as EOG, is a test that measures eye movement using an electrooculograph. It allows for the evaluation of eye movements, typically with dilated pupils. During electrooculography, electrical impulses associated with eye movements are recorded. Electrooculography is used in polysomnographic studies to observe eye activity during specific stages of sleep.

ENDOPROTHESIS

Endoprosthesis is an artificial structure that replaces a natural joint in the human body. The purpose of an endoprosthesis is to mimic the movements and functions of the original joint. They are typically made of titanium and steel alloys. The most common endoprosthesis is the hip prosthesis, while knee prostheses are less common. After implantation of an endoprosthesis, attention should be paid to sleeping in a physiological position, which not only serves a role in rehabilitation and treatment but also helps prevent recurrence of the conditions that led to the implantation, for which a medical mattress is used.

ENDORPHIN

Endorphins are hormones mainly produced by the pituitary gland. They play a significant role as neurotransmitters responsible for euphoria and a sense of well-being, which is why they are also known as "happiness hormones." There are at least 20 different types of endorphins, although their effects are similar. Adequate levels of endorphins allow for a peaceful and restorative sleep.

EPIPREMNUM

Epipremnum is a houseplant from the Araceae family. It is also one of the air-purifying plants that efficiently absorb volatile organic compounds, carbon monoxide, benzopyrene, and lead. Epipremnum is also capable of purifying the air from ammonia, benzene, xylene, toluene, trichloroethylene, and formaldehyde.

ERGONOMICS

Ergonomics is a scientific discipline that deals with adapting the environment to work conditions that correspond to the anatomical, biological, and psychological capabilities of humans. On the one hand, its aim is to provide humans with appropriate conditions for maintaining health, while on the other hand, it aims to increase their efficiency during work or other activities. It is essential to have objectively evaluated sleeping products that are ergonomic to increase sleep hygiene, which allows humans to function better during the day.

ERGOTHERAPY

Ergotherapy is a branch of physiotherapy that uses the therapeutic effects of everyday activities. As part of occupational therapy, a person is encouraged to be more active in order to improve their physical function and coordination.

ESTRADIOL

Estradiol, also known as E2, is a hormone primarily produced by the ovaries but also by the testes. It plays a key role in the development of female reproductive organs and the motility of sperm. An increase in estradiol levels leads to an elongation of the REM phase during sleep, which is associated with dreaming.

ESTROGEN

Estrogen is a hormone produced mainly by the ovaries but also by the testes, brain, and adipose tissue. There are three chemically similar types of estrogen: estradiol, estriol, and estrone. Estrogens play a significant role in the development of sexual desire and sexual characteristics. An increase in estrogen levels leads to an elongation of the REM phase during sleep, which is associated with dreaming.

SLEEP STAGE NREM

NREM sleep stage is the first stage of sleep, characterized by slow eye movements. During NREM sleep, the body is resting and regenerating.

SLEEP STAGE REM

REM sleep stage is the second stage of sleep, characterized by rapid eye movements. During REM sleep, dreaming occurs and the body is in a state of readiness.

FICUS ELASTICA

Ficus elastica is an indoor plant belonging to the family Moraceae. It is also one of the air-purifying plants that is excellent at absorbing volatile organic compounds, carbon monoxide, benzopyrene, and lead. Ficus elastica also has the ability to purify the air from ammonia, benzene, xylene, toluene, trichloroethylene, and formaldehyde.

PHYSIOLOGY

Physiology is a field of science that studies the mechanisms governing the life processes of organisms. Knowledge of physiology enables the creation of mattresses, pillows, and other sleep products that provide optimal body support and spinal support for the highest level of sleep hygiene.

PHYSIOGNOMY

Physiognomy refers to the distinctive features that a particular material possesses. In the case of humans, physiognomy has a strong connection to anatomy. Knowledge of physiognomy enables the creation of mattresses, pillows, and other sleep products that provide optimal body support and spinal support for the highest level of sleep hygiene.

PHYSIOTHERAPY

Physiotherapy is a field of science that deals with the prevention, treatment, and rehabilitation of specific conditions that disrupt physical functionality. With knowledge in the field of physiotherapy, it is possible to create mattresses, pillows, and other sleeping products that ensure the highest hygiene of sleep with optimal body support and spinal support. Physiotherapy is divided into various branches, the most popular of which are:
  • physical therapy;
  • kinesiotherapy;
  • occupational therapy;
  • hydrotherapy;
  • balneotherapy;
  • climatotherapy;
  • therapeutic massage;
  • manual therapy.

PHYSICAL THERAPY

Physical therapy is one of the branches of physiotherapy. It uses the therapeutic effects of physical factors such as light, heat, and cold. The therapeutic treatments within physical therapy include magnetotherapy, light therapy, laser therapy, hydrotherapy, and electrotherapy.

FOLLICULOTROPIN

Folliculotropin, also known as FSH, is a hormone produced by the pituitary gland. It plays a significant role in the reproductive system as it is responsible for the maturation of Graafian follicles in the ovaries and spermatogenesis. It also influences the stimulation of estrogen and testosterone, making its proper level crucial for maintaining sexual health.

FORMALDEHYDE

Formaldehyde is a formic aldehyde. It is an organic chemical compound, and its aqueous solution is called formalin. It has been proven many times that formaldehyde is toxic and harmful to human health. Despite this, it is still used in the production of most latex mattresses and many coconut fiber mattresses. Therefore, they are not good products for people who care about healthy and comfortable sleep.

FUNCTIONALITY

Functionality is a characteristic that indicates that something performs its functions well. A functional product is one whose essential elements are made of the highest quality materials, and its unnecessary elements are entirely eliminated. This links functionality directly to rationality and simplicity. This understanding of functionality allows for the creation of products that provide comfort and long life. Therefore, assessing the functionality of a product is crucial before purchasing it, especially before buying a mattress or pillow, as it directly affects daily biopsychosocial functioning.

BIOPSYCHOSOCIAL FUNCTIONING

Biopsychosocial functioning is the overall biological, psychological, and social functions of a human being. Biopsychosocial functioning consists of many elements, including somatic health and mental health. Environmental factors, such as surroundings and cultural patterns, also have a significant impact on biopsychosocial functioning. Quality sleep and actions that resemble homeostasis serve to improve biopsychosocial functioning.

FUTON

Futon is a traditional bed that originated in Japan. A futon is a thin mattress that is most commonly filled with natural materials. The use of futons stems from Japanese tradition, but their use now results from the decreasing living spaces in Japan. Futons are not capable of providing proper body support and spinal support in a physiological position.

GLYPHOSATE

Glyphosate is an organic chemical compound that belongs to the group of phosphonates. It is primarily used in herbicides, which are substances used to control weeds. Increasingly, it is also being used in the production of cotton, flax, and hemp. However, many scientific studies have shown that it increases the risk of cancer. In addition, it can cause hormonal disorders, autism, Alzheimer's disease, and Parkinson's disease. Although it has been banned in many countries, textile materials produced from fibers grown using glyphosate are widely available.

GLUCAGON

Glucagon is a hormone produced by the pancreas. It works in the opposite way to insulin, causing an increase in blood glucose levels. In this way, it prevents hypoglycemia. Its physiological level is crucial for maintaining appropriate glycemia and thus for carbohydrate metabolism and maintaining the proper level of energy.

HUMP

Hump is a visible protrusion on the back, neck, or shoulders. It is most often the result of the deepening of thoracic kyphosis and thus results from spinal defects. Another protrusion on the back is a widow's hump, which consists of connective tissue and adipose tissue and is therefore an unsightly growth not related to the spine.

DENSITY

Density is the ratio of the mass of a substance to the volume it occupies. In physics, density is expressed in kg/m3, or kilograms per cubic meter. Many mattress manufacturers and sellers mislead consumers into believing that the density of polyurethane foams is equal to their hardness. In reality, these are two different parameters. Both the density and hardness of the materials from which the mattress is made are crucial for sleep hygiene and the durability of the product.

GLUCOSE

 

Glucose is an organic compound that is a monosaccharide or simple sugar. It is the primary source of energy for humans, as the human brain uses about 120 grams of it every day. The level of glucose in the blood is indicated by glycemia, so low glucose levels are called hypoglycemia and high levels are called hyperglycemia. Hormones, especially insulin and glucagon, regulate the level of glucose in the blood.

 

THYMUS

Thymus is a gland located behind the sternum. It produces thymosin, humoral thymic factor, thymulin, thymopoietin, thymopentin, and thymostimulin.

GLAND

Gland is a group of cells or an organ that secretes specific substances. In the case of sleep, the most important are the endocrine glands, which are responsible for secreting hormones. The digestive glands, which are responsible for digestion, are also very important. In the case of sweating at night, the sweat glands are worth paying attention to. Mammary glands and sebaceous glands are less important for sleep health.

GUARANINE

Guaranine is an organic compound that is a purine alkaloid. It has psychoactive and stimulating properties and is often used as an additive in energy drinks. Guarana is where it gets its name, but if it comes from another source, it is called something else. Due to its stimulating properties, it is not recommended to drink it before sleep.

HYPERCAPNIA

Hypercapnia is a condition of elevated partial pressure of carbon dioxide (pCO2) in human blood. It is considered hypercapnia when the pCO2 level is above 6.0 kPa (45 mm Hg). It can lead to disorientation, seizures, hyperventilation, and even death. It often occurs during sleep apnea, so proper sleep hygiene and appropriate treatment should be implemented to prevent it.

HIPNOSIS

Hypnosis is a therapeutic technique that involves inducing a state of increased susceptibility to suggestion in a patient, used in sleep therapy among other applications.

HIPOCAPNIA

Hypocapnia is a condition of reduced partial pressure of carbon dioxide (pCO2) in human blood. It is considered hypocapnia when the pCO2 level is below 4.7 kPa (35 mm Hg). It can lead to dizziness, ringing in the ears, muscle weakness, and even apnea and reflexive brain ischemia. Hypocapnia is often mistaken for night terrors, so it is important to consult a doctor.

HYPOXEMIA

Hypoxemia is a condition in which the level of oxygen in the blood falls below normal, which can lead to serious health disturbances, including difficulty falling and staying asleep.

HIPOXIA

Hypoxia is a condition of oxygen deficiency in the tissues caused by reduced oxygen access, which can affect sleep quality and lead to sleep disorders.

HORMONE

Hormone is an organic compound responsible for regulating and coordinating chemical processes in cells and tissues of the body. Their task is to control all physiological processes and adjust them to environmental conditions. Hormones act by transmitting information between organs.

REWARD HORMONE

Reward hormone is a colloquial and popular name for dopamine, which is responsible for regulating and coordinating processes associated with the pleasure center.

SLEEP HORMONE

Sleep hormone is a colloquial and popular name for melatonin, which is responsible for regulating and coordinating processes associated with sleep.

STRESS HORMONE

Stress hormone is a colloquial and popular name for cortisol, which is responsible for regulating and coordinating processes associated with stress.

HAPPINESS HORMONE

Happiness hormone is a colloquial and popular name for serotonin, which is responsible for regulating and coordinating processes associated with mood. Endorphins, whose action is similar, are sometimes also referred to as the happiness hormone.

HYDROTHERAPY

Hydrotherapy is a branch of physiotherapy that utilizes the therapeutic effects of water. Treatment procedures in hydrotherapy include primarily baths, rinses, and showers.

INSOMNIA

Insomnia, also known as sleeplessness, is an increasingly common sleep disorder that involves difficulties in falling asleep, maintaining sleep, and/or waking up too early. The criteria for diagnosing insomnia also include its impact on daily functioning. Poor sleep hygiene contributes to its occurrence.

INSULIN

Insulin is a hormone produced by the pancreas. It works opposite to glucagon, causing a decrease in blood glucose levels. In this way, it prevents hyperglycemia. Its physiological level is crucial for maintaining appropriate glycemia, and thus for carbohydrate metabolism and maintaining proper energy levels.

SMART ALARM CLOCK

Smart alarm clock is an mobile app or device used to measure sleep parameters and wake up the user at the optimal time to provide them with the best sleep and a smooth transition from sleep to activity.

JACEK

Jacek is one of the most popular names in the world. The origin of this name comes from the Greek name Hyakinthos, which was also Latinized to the name Hiacynt. It is also the name of Jacek Ciesielski, a sleep expert, whose expertise led to the creation of the ONSEN® brand, which produces the best products for comfortable and healthy sleep.

OVARIES

Ovaries are glands located in the lower abdomen. They mainly produce estradiol, progesterone, and relaxin.

SLEEP PILLOW

Sleep pillow is a common name for a pillow made of natural materials, often used as an element of a healthy bedroom.

TESTICLES

Testicles are glands located in the scrotum. They mainly produce testosterone.

SILK

Silk is a fabric with a very delicate and soft texture, often used as a material for bedding, especially for people with sensitive skin.

JOBS TO BE DONE

Jobs to be done is a theory that states that consumers do not buy a product just for the sake of owning it, but to satisfy specific needs. According to the jobs-to-be-done method, every product should have functionalities that address real consumer needs. Its application in the production of mattresses and pillows allows for maintaining a healthy and comfortable sleep.

IONIZATION

Ionization is the process of imparting ion characteristics to an atom or molecule. This ion can be either a cation or anion. In the case of the bedroom, air ionization is important because harmful substances change their electric charge and settle on flat surfaces. This allows for their mechanical removal. Ionization itself does not remove pollutants.

CALCITONIN

Calcitonin is a hormone produced by the thyroid gland. It plays a crucial role in regulating carbonate and phosphate metabolism. It also inhibits excessive bone resorption, preventing bone loss and osteoporosis.

KAMASUTRA

Kamasutra is an Indian treatise written in Sanskrit. Its author is Vātsyāyana Mallanaga, an Indian poet. Kamasutra is about sexuality and sexual behavior, but it also discusses the contemporary culture. It is widely considered a philosophical work aimed at bringing happiness to humans.

CANNABIDIOL

Cannabidiol, also known as CBD, is an organic compound mainly found in Indian hemp. It is attributed with anti-cancer properties and a positive impact on mood. Cannabidiol also has appetite-increasing effects. Many studies also indicate its neuroleptic, neuroprotective, anticonvulsant, and antispasmodic effects.

CANNABIGEROL

Cannabigerol, also known as CBG, is an organic compound mainly found in Indian hemp. It is attributed with anti-anxiety and pain-relieving effects. Cannabigerol also has appetite-increasing effects. Some studies suggest that it lowers HDL cholesterol levels.

SLEEP CALCULATOR

Sleep calculator is a simple tool that uses an algorithm to determine how long one should sleep. The goal of the sleep calculator is to wake up during the REM phase, which is a shallow sleep. With sleep calculators, you can calculate when to wake up to feel rested. Additionally, a sleep calculator is useful for calculating sleep time in polyphasic sleep.

SOFA

Sofa is a piece of furniture designed for seating and relaxation, but it can also be a potential source of back pain and other health issues, especially if used for sleeping.

CAROTENOIDS

Carotenoids are unsaturated hydrocarbons with a unique structure. Carotenoid molecules contain at least 7 double bonds. In nature, carotenoids serve as a natural pigment for plants, fungi, and bacteria. For humans, carotenoids play a crucial antioxidative role. They are used in the Skin+ technology, influencing skin nourishment and regeneration during sleep.

KYPHOSIS

Kyphosis is a natural, physiological curvature of the thoracic and sacral spine. It involves bending a specific section of the spine in a backward arc. In other parts of the spine, the presence of kyphosis is a pathological condition, deviating from the norm. 

LORDOTIC KYPHOSIS

Lordotic kyphosis is a natural, physiological curvature of the lumbar spine. Therefore, it raises no concerns about health. Lordotic kyphosis involves bending a section of the spine in a backward arc.
