What is cortisol?
Cortisol is a vital hormone that is produced in the adrenal cortex and plays a key role in many bodily functions. It is often referred to as the stress hormone, as it plays a central role in stress reactions. But cortisol is far more than just a stress hormone; it is crucial for a normal and healthy life.
One of the main functions of cortisol is to regulate sleep and fat metabolism. It helps the body to cope better with stress and increases resilience. Cortisol also protects the body in acute stress situations and has an anti-inflammatory effect.
Cortisol also plays an important role in the conversion of proteins into glucose, providing a crucial source of energy for the body. These diverse functions make it clear why it is so important to keep cortisol levels in balance.
The role of the adrenal cortex
Cortisol is produced in the adrenal cortex, a part of the adrenal gland that sits on top of the kidneys. The adrenal cortex is responsible for the production and regulation of various steroid hormones, including cortisol, which has a significant influence on metabolism.
The production of cortisol is controlled by a complex regulatory circuit initiated by the brain. The hypothalamic-pituitary-adrenal system (HPA axis) plays a central role in this process. The hypothalamus releases corticotropin-releasing hormone (CRH), which stimulates the pituitary gland to secrete adrenocorticotropic hormone (ACTH). This hormone ultimately stimulates the adrenal cortex to produce cortisol. The sex hormones oestrogen, progesterone and testosterone are also stimulated and produced via the same axis. A permanently increased release of cortisol can therefore massively impair the female hormone balance.
This control circuit ensures that the cortisol level in the blood is kept at an optimal level. An increase in CRH and ACTH leads to a higher release of cortisol, while an excess of cortisol reduces production. In this way, the system helps the body to keep the hormones cortisol, noradrenaline and adrenaline cortisol in balance.
Diurnal fluctuations in cortisol
Cortisol levels in the body fluctuate significantly depending on the time of day. Cortisol levels are highest in the morning, which helps the body to start the day feeling energised and alert. In the evening, as we prepare for sleep, levels drop to their lowest point.
These fluctuations are essential for various bodily functions, including metabolism and stress response. A stable circadian rhythm is therefore important to keep cortisol in balance and promote general health.
However, problems can occur when the natural circadian rhythm is disrupted, whether through shift work, lack of sleep or chronic stress. Such disruptions can lead to a permanently elevated cortisol level, which in turn causes health problems.
Positive effects of cortisol
Cortisol has many positive effects on the body. It is crucial for the provision of energy by converting proteins into glucose. This glucose serves as a quick source of energy, especially in stressful situations or during increased physical activity.
The stress hormone also promotes the mobilisation of energy reserves and activates the fat metabolism. This makes the body more efficient in the short term and helps it to function efficiently in stressful situations. At the same time, the stress hormone fulfils a protective function in the body by raising blood pressure and increasing the respiratory rate. Stress helper today, stress maker tomorrow.
Cortisol also has anti-inflammatory properties and supports the immune system. In acute stress situations, it therefore not only helps to increase physical performance, but also to inhibit inflammation and strengthen the immune system.
Negative effects of chronically elevated cortisol
However, long-term elevated cortisol levels can also have numerous negative effects on health. The most common problems include sleep disorders and a weakened immune system. A chronically elevated cortisol level can also increase the risk of diabetes, as it causes blood sugar levels to rise.
In addition, a permanently high cortisol level can favour chronic high blood pressure and coronary heart disease. Psychological symptoms such as low mood, anxiety and depression can also occur if cortisol levels are elevated over a long period of time. A high cortisol level can also cause cortisol to make you ill. Elevated cortisol levels can also cause the adrenal glands to produce fewer sex hormones, which can lead to an imbalance in oestrogen and progesterone levels.
Another typical symptom is skin changes such as acne or thinning skin caused by increased cortisol levels. All of these aspects show how important it is for the symptoms listed above to occur in order to keep cortisol levels in a healthy balance.
Causes of elevated cortisol levels
There are several causes for an elevated cortisol level:
- Chronic stressThe physical as well as the emotional nature of the work is a key factor.
- Intensive physical strain can also lead to an increase in cortisol levels.
- Unhealthy eating habits can also lead to an increase in cortisol levels.
Excessive consumption of Stimulants such as caffeine also contributes to an increase in cortisol levels. Lack of sleep is another common cause, as it leads to a vicious circle of sleep disorders and increased stress.
Finally, illnesses and injuries can also cause cortisol levels to rise, as the body reacts to stress in such situations. It is therefore important to identify the causes and address them specifically in order to keep cortisol levels in balance.
Symptoms of an elevated cortisol level
An elevated cortisol level can cause various symptoms. One common symptom is weight gain, as the body stores more fat in stressful situations. Chronic stress and high cortisol levels can also cause sleep disorders, leading to poor sleep quality and fatigue. Chronic fatigue syndrome (CFS) can also play a role.
Difficulty concentrating and memory problems are also possible consequences of chronically elevated cortisol levels. These symptoms can make everyday life stressful and difficult and significantly impair quality of life.
It is important to recognise these symptoms early and take measures to naturally reduce cortisol levels and restore balance in the body.
Cortisol and its connection to other stress hormones
Cortisol is just one of several stress hormones produced in the adrenal cortex. Together with noradrenaline and adrenaline, it plays a central role in the body's stress response. During acute stress, the production of these hormones increases in order to prepare the body for possible challenges. The stress hormone cortisol plays a decisive role in regulating the reaction.
Cortisol helps to provide the brain with glucose in order to increase concentration and performance. At the same time, it ensures that noradrenaline and adrenaline are released, which increases alertness and physical responsiveness.
These hormones work together to optimally support the body in stressful situations. However, an elevated cortisol level over a longer period of time can disrupt the balance of the stress hormone cortisol and lead to health problems.
Methods for lowering the cortisol level
There are various methods to reduce cortisol levels naturally. Finding a balance between good and bad stress is crucial. Simple lifestyle changes, such as regular exercise and sufficient sleep, can help to lower cortisol levels.
A balanced diet with increased consumption of fibre, omega-3 fatty acids and potassium-rich foods can also help to regulate cortisol levels. Specific methods for lowering cortisol levels through exercise, evening rituals and relaxation techniques are explained in more detail below.
Exercise and sport
Regular exercise and sport are excellent ways of lowering cortisol levels. Exercise reduces cortisol levels and activates endorphins, which leads to a better sense of well-being. In the long term, regular physical activity can stabilise cortisol levels and reduce general stress levels.
A healthy morning routine that includes physical activity helps to start the day agile and clear-headed and improves concentration. However, it is important to adjust the intensity of activities to avoid overexertion.
Evening rituals for better sleep
Good evening rituals are crucial for lowering cortisol levels and sleeping better. Excessively intense sports in the evening can cause problems falling asleep and should therefore be avoided. Instead, a relaxing evening ritual can help you wind down at the end of the day.
Calming activities such as reading, a warm bath or gentle stretching can ease the transition to sleep. Create a relaxed sleeping environment by switching off electronic devices at least one hour before going to bed and creating a quiet, dark sleeping environment.
Regular bedtimes and a consistent evening routine can also help to stabilise cortisol levels and improve sleep quality. All of these measures help to provide the brain with glucose and thus promote nightly regeneration.
Relaxation techniques and me-time: yin yoga, mindfulness, meditation
Relaxation techniques are another important component in lowering cortisol levels. Yoga, especially yin yoga, has been shown to have positive effects on cortisol levels. This gentle yoga practice focuses on stretching the deep connective tissue and promotes deep relaxation.
Mindfulness training can also help to recognise and manage stress-related thoughts. Here are some tips to effectively lower your stress levels and keep your cortisol levels in balance:
- Schedule regular time for yourself.
- Enjoy Me-Time to relax and regenerate.
- Practise mindfulness exercises to be present in the moment.
- Use meditation or breathing techniques to cope with stress.
By implementing these strategies, you can increase your well-being and cope better with stress.
Studies have shown that Yin Yoga activates the parasympathetic nervous systemwhich is responsible for relaxation and regeneration. This reduces the production of stress hormones and lowers cortisol levels, which leads to a more balanced and healthier life and prevents exhaustion.
Meridians and TCM - balance for body and mind
Meridians play a central role in Traditional Chinese Medicine (TCM). These energy pathways run through the body and transport the "Qi" (life energy). According to TCM, an imbalance or blockages in the flow of Qi can lead to health problems, including increased stress and a disturbed cortisol balance.
Acupuncture and acupressure are TCM techniques that can help to release these blockages and restore balance in the body. These methods can lower cortisol levels by reducing stress and balancing the HPA axis. Herbal treatments, which are often used in TCM, also support the function of the adrenal glands and thus help to regulate cortisol levels.
Yin yoga, which is also used in TCM practice, works with the meridians and promotes relaxation, which further reduces cortisol levels. These holistic approaches offer a valuable addition to Western methods of stress management and help to balance body and mind.
Summary
Cortisol is a vital hormone with many positive effects, but also potentially harmful effects if levels are chronically elevated. It plays a crucial role in the body's stress response, energy supply and the regulation of metabolic processes. At the same time, a permanently elevated cortisol level can lead to health problems such as sleep disorders, high blood pressure and psychological symptoms.
It is important to recognise the causes of elevated cortisol levels and address them in a targeted manner. Chronic stress, lack of sleep and unhealthy eating habits are common triggers. By incorporating regular exercise, healthy evening rituals and relaxation techniques into your daily routine, you can naturally lower your cortisol levels and find a balance between good and bad stress.
Traditional Chinese Medicine and Yin Yoga based on it with passive, long postures offer additional approaches to regulate cortisol levels and promote health. Ultimately, it is crucial to listen to your body's signals and take steps that contribute to a balanced and healthy life.
