Adrenaline – significance, function, deficiency, excess30 września 2022 |

Adrenaline is called the hormone of fear, fight, and flight, as it is a key neurotransmitter produced by the adrenal glands. Its main task is to mobilize the body to quickly respond in stressful and dangerous situations. An increase in adrenaline levels in the blood allows for rapid adaptation to changing conditions, influencing heart activity, metabolism, and the functioning of the nervous system.
Norepinephrine, which belongs to the catecholamine group, is produced directly in the adrenal medulla in response to stress stimuli. It stimulates the sympathetic nervous system, triggering a series of physiological reactions. Their main purpose is to prepare the body for exertion, especially intense exertion.
As a result of adrenaline's action, the body accelerates the heart rate. This, in turn, is associated with an increase in blood pressure and dilation of the bronchi, improving oxygen supply. Epinephrine also causes mobilization of glucose from the liver, allowing it to be delivered to the muscles. In addition, it constricts blood vessels in the digestive organs to redirect blood to the muscles at the expense of digestion processes. All this causes an increase in concentration and alertness, helping to react more quickly to threats.
Although adrenaline is mainly associated with stressful situations, the level of epinephrine also rises during moments of euphoria and strong emotions, regardless of their cause. This can be the result of intense physical effort or excitement, but also experiencing other events. For this reason, adrenaline is also called the hormone of excitement.
In principle, the proper concentration of adrenaline in the blood serum of adults should be from 240 pmol/l to 480 pmol/l, i.e., from 43.92 pg/ml to 87.84 pg/ml. However, it is worth noting that adrenaline levels can vary depending on the conditions of the study.
Adrenaline plays a key role in regulating bodily functions, which is why its deficiency can lead to serious health consequences. Low adrenaline levels are most commonly caused by adrenal gland disorders, but they can also result from hormonal imbalances in other glands that are linked to them.
As a rule, adrenaline deficiency is usually associated with dysfunction of the endocrine system, particularly the adrenal glands, which produce it. The most commonly reported causes of low epinephrine levels include:
Persistently low adrenaline levels can lead to a range of symptoms affecting daily life. The most common effects of adrenaline deficiency include:
Adrenaline deficiency is a dangerous condition that can significantly impact quality of life, directly leading to body weakness, circulatory problems, and mood disorders. If symptoms indicating a low adrenaline level occur, it is essential to consult a doctor.
Adrenaline plays a crucial role in the body's response to stress. However, when there is an excess of epinephrine in the body, it can lead to various health issues. High adrenaline levels can be caused by chronic stress, certain medical conditions, or a life full of tension.
In general, excess adrenaline can result from various physiological and environmental factors. The most significant include:
An excessive amount of adrenaline can lead to various undesirable effects, including:
In the case of excess adrenaline, it is important to take steps to mitigate its negative effects. Reducing stress and ensuring proper rest can help, unless medical intervention is necessary.
If you notice symptoms of excess adrenaline, it is essential to consult a doctor who can determine the cause of the condition and recommend appropriate treatment.
Our psychologist, Mateusz Nesterok, a specialist in health psychology and rehabilitation, highlights the importance of maintaining an optimal adrenaline level in the body. While this hormone plays a key role in daily functioning, its excess can lead to serious health consequences. An excessively high adrenaline level is associated with hypertension and dizziness, as well as anxiety disorders and psychosomatic depression. Its impact on sleep is also significant, as an excess of epinephrine in the blood can cause insomnia and lower sleep quality.
He also points out that a low adrenaline level is not beneficial either. Although it is rare, it is important to remember that an adrenaline deficiency can lead to decreased concentration and weakened cognitive functions. It can also hinder weight loss and even promote weight gain. Any disruption of hormonal balance has a significant impact on human functioning.
As scientific research proves, maintaining an adequate amount of sleep at night helps lower adrenaline levels in the blood. This demonstrates that adrenaline is strongly related to the sleep-wake cycle, making it essential to maintain proper levels. Moreover, research results indicate that reducing adrenaline concentration in the blood lowers body temperature and reduces fatigue.
To ensure proper body regeneration, it is crucial to focus on comfortable sleep, which effectively supports hormonal balance on multiple levels. A key element is a truly comfortable mattress, which also provides proper body support and relieves the spine. Only in this way can the body fully relax, positively affecting the hormonal system.

Adrenaline is responsible for the body's proper response in dangerous situations. That is why it is often called the hormone of fear, fight, and flight. Additionally, adrenaline is produced during states of euphoria.
The primary effect of adrenaline deficiency or low levels is tachycardia. Additionally, a lack of adrenaline can lead to low blood pressure and chronic fatigue. Low adrenaline levels also cause difficulties with weight loss but, most importantly, severe mood and sleep disorders.
The primary effect of excess or high levels of adrenaline is bradycardia. Additionally, high adrenaline levels can cause high blood pressure, dizziness, and vision disturbances. It also triggers unnecessary anxiety. People with excessive adrenaline often experience physical and mental exhaustion. Furthermore, adrenaline contributes to anxiety disorders, mood disorders, and difficulties in falling and staying asleep.
Adrenaline production can be increased through physical activity and experiencing more states of euphoria. Additionally, certain medications can stimulate adrenaline release.
Adrenaline production can be reduced by leading a calm lifestyle and avoiding stress. Moreover, adrenaline levels decrease with the release of endorphins, so it is beneficial to be happier. Lowering adrenaline levels in the blood can also be achieved through sex and a proper diet.
