Stress in everyday life
In our fast-paced world, the demands on body and mind are constantly increasing, and many people feel increasingly overwhelmed and stressed. Chronic stress is one of the main triggers for the so-called burnout syndrome – an exhaustion crisis that can have serious health consequences in many cases.
A central role in stress management is played by the hormone cortisol. But why is the cortisol level so important? In this article, we take a look at the function of cortisol, the importance of a healthy cortisol level, and the reference ranges used to assess this value. Additionally, we introduce other important values that contribute to stress and burnout diagnosis.
We also recommend the excellent article by AOK for more in-depth information: How Cortisol and Stress are Related as well as the article by Helios Health.
Cortisol – the stress hormone
Cortisol, often referred to as the "stress hormone" , is produced in the adrenal cortex and plays a central role in responding to stressful situations. During stress phases, cortisol levels rise to make the body alert and release energy reserves – an adaptation that was crucial for survival in human evolution to quickly respond to threats.
When stress becomes a constant burden
In a healthy body, cortisol levels normalize after a stress phase. However, with persistent stress or chronic overload , cortisol levels often remain permanently elevated.This can lead to a variety of health problems, including:
- Sleep disorders
- Weight gain
- Depression
- Weakened immune defense
Stress management for a healthy cortisol level
Targeted stress management and a balanced lifestyle can help regulate cortisol levels again. This includes getting enough sleep, regular exercise, relaxation techniques such as meditation or breathing exercises, and a healthy diet.
Cortisol and Burnout: A Dangerous Combination
Burn-out is far more than "just" stress – it is a profound physical and mental exhaustionthat is often closely associated with a disrupted cortisol level .
Initially, chronic stress often leads to permanently elevated cortisol levels, which is a clear sign of overload and significantly increases the risk of burn-out . However, in the advanced stage of burn-out, the cortisol level can drastically drop: The adrenal glands are overworked and no longer produce sufficient cortisol. This is an indication that the body has exhausted its adaptive capacity .
Cortisol levels and reference ranges
Measurement instructions
To correctly interpret the cortisol level , it is important to know the natural fluctuations throughout the day. Cortisol follows a circadian rhythmthat varies depending on the time of day.
In the morning , the cortisol level reaches its peak to activate the body for the day and enhance performance. Over the course of the day, the level should gradually decrease so that it is low in the evening , helping the body to relax and fall asleep.
Disruptions of this rhythm – such as consistently elevated levels or a high cortisol level in the evening – can indicate chronic stress, burnout , or other stress-related disorders . Accurate measurement helps to detect these deviations early and counteract them specifically.
Reference ranges depending on the time of day
The cortisol level varies throughout the day and follows a natural rhythm. The reference values for healthy adults are:
Morning (7–9 AM): 200–700 nmol/L
Afternoon: 100–400 nmol/L
Evening: < 100 nmol/L

Cortisol Imbalance: Recognize Symptoms
An imbalanced cortisol level – whether persistently elevated or too low – can affect the entire body. Since cortisol plays a key role in energy balance and stress management , imbalances often lead to symptoms that develop gradually and are easily overlooked or attributed to other health issues.
Symptoms of elevated cortisol levels:
- Chronic fatigue and exhaustion: Despite adequate sleep, affected individuals feel constantly tired and lacking energy.
- Weight gain, especially around the abdomen: Cortisol promotes fat storage, particularly in the abdominal region.
- Sleep disturbances: An elevated cortisol level makes it difficult to fall or stay asleep, especially in the early morning hours.
- Concentration and memory problems: High cortisol levels impair brain function and lead to concentration difficulties.
- Mood swings and irritability: A disrupted cortisol level affects the neurotransmitters, which can lead to mood swings and irritability.
- High blood pressure and heart palpitations: Cortisol increases heart rate and can raise blood pressure in the long term – a risk factor for cardiovascular diseases.
- Weakened Immune System: A persistently elevated cortisol level weakens the immune system and increases susceptibility to infections.
Important: If you notice one or more of these symptoms, a cortisol test can provide valuable insights. Early diagnosis and targeted measures can effectively manage the effects of a disrupted cortisol level.
Specific symptoms in women
An imbalanced cortisol level can cause additional or intensified symptoms in women, closely related to hormonal fluctuations and the menstrual cycle .
Typical symptoms in women:
- Irregular menstrual cycle or missed periods: A persistently high cortisol level affects the hormonal balance and can lead to menstrual disorders .
- Changes in skin health: Many women experience increased skin problems, such as acne or dry skin, with elevated cortisol.
- Increased hair loss: Hormonal imbalances and persistent stress can lead to hair loss or thinning hair.
- Stronger PMS Symptoms: Women often report increased premenstrual complaints such as headaches, mood swings, and water retention.
- Loss of Libido: A disrupted cortisol level can affect sex hormones, such as testosterone, and decrease sexual interest .
- Increased Risk of Osteoporosis: Long-term high cortisol levels can reduce bone density and thus increase the risk of osteoporosis, especially in women.
Cortisol and the Female Body
These symptoms illustrate how significantly the hormone Cortisol can influence not only the general state of health but also the female hormonal balance and well-being . Early monitoring of cortisol levels provides women with the opportunity to take targeted countermeasures and support their health sustainably.
Additional relevant values for burnout diagnosis
In addition to cortisol levels, there are other important blood values that provide information about the body's stress load and degree of exhaustion:
- Folic Acid: Folic acid is essential for cell regeneration and the production of neurotransmitters. A folic acid deficiency can contribute to exhaustion, cognitive impairments, and impaired stress management. Folic acid is also important for blood formation and the nervous system.
- Transcobalamin (Vitamin B12 transport protein): Transcobalamin binds vitamin B12 and transports it into the cells.A deficiency can lead to vitamin B12 deficits, which impair the nervous system and cognitive function, promoting symptoms such as fatigue, mood swings, and memory problems – symptoms often associated with burnout.
- DHEA (Dehydroepiandrosterone): DHEA is a hormone that is also produced in the adrenal glands. A healthy DHEA level is important because an imbalance between DHEA and cortisol can indicate chronic stress.
- CRP (C-reactive protein): A marker for inflammation in the body. Chronic stress can lead to an increased tendency for inflammation, which can be measured by the CRP level.
- Vitamin D: Vitamin D is important for the immune system and overall energy production.A low vitamin D level can contribute to fatigue and susceptibility to illnesses. Blood sugar: Stress can increase blood sugar as cortisol boosts the body's glucose output. Prolonged elevated blood sugar can indicate chronic stress. Thyroid levels (TSH, T3, T4): Since the thyroid also responds to stress, altered thyroid levels can be a sign of body exhaustion. By combining these values, the health status can be better assessed, and the relationship between stress and physical condition can be determined more precisely.
