Today we want to delve deep into the fascinating world of the hormone cortisol and take a closer look at its complex role in stress and the positive and negative effects it has on your body. In this article, you will find out how you can manage this double sword of hormones in your everyday life to promote your well-being.
Cortisol and stress:
Cortisol is a true masterpiece of nature when it comes to preparing you for stressful situations. When you are exposed to a dangerous stimulus, be it a loud noise or a threatening situation, your body sets off a chain reaction.
The hypothalamic-pituitary-adrenal axis, also known as the HPA axis, is activated. The hypothalamus gland sends a signal to the pituitary gland, which in turn stimulates the adrenal glands to release cortisol. This process allows you to react quickly, whether through flight or fight.
The circadian rhythm and the role of cortisol:
Your body follows a natural daily rhythm, the circadian rhythm. Cortisol plays a key role in this rhythm. Cortisol production is highest in the morning, which helps you to start the day feeling active and alert. As the day progresses, production decreases to help you wind down in the evening. A well-functioning circadian rhythm is essential for your sleep-wake cycle and your general well-being.
Melatonin and the sleep-wake cycle:
While cortisol gets you going in the morning, melatonin is the hormone that accompanies you to sleep. The pineal gland produces melatonin when it gets dark, signaling to your body that it's time to rest. Melatonin helps to improve your sleep quality and regulate your sleep-wake cycle.

Positive effects of cortisol:
Cortisol is therefore your faithful companion in overcoming challenges. It increases your alertness, your energy and your ability to react. This can be a lifesaver in critical moments. Cortisol also plays an important role in inhibiting inflammation and regulating the immune system.
Negative effects of cortisol:
However, as is so often the case in life, too much of a good thing can lead to negative consequences. Chronic stress leads to an excessive release of cortisol, which can harm your body in the long term. You may have trouble falling asleep as your elevated cortisol levels disrupt your natural sleep-wake cycle. Your immune system could be weakened, which could lead to more frequent infections. The constant "on" signal for your fight-or-flight system could even lead to an increased risk of cardiovascular disease and gastrointestinal problems.
These signs indicate high or low cortisol levels
It's important to recognize your body's signs to determine if your cortisol levels are too high or too low. A balanced cortisol level is crucial for your wellbeing. Here are some signs that could indicate that your cortisol levels are not in the optimal range:
Signs of high cortisol (hypercortisolism):
Difficulty falling asleep or staying asleep: Elevated cortisol levels in the evening can disrupt your sleep-wake cycle and lead to sleep problems.
Weight gain: Chronically elevated cortisol can slow down your metabolism and lead to weight gain, especially in the abdominal area.
Mood swings: High cortisol levels can lead to anxiety, irritability and nervousness.
Fatigue: Paradoxically, persistently high cortisol levels can lead to persistent fatigue despite an initial increase in energy.
Increased blood pressure: Chronically elevated cortisol levels can cause blood pressure to rise.
Decreased immune function: Excessively high cortisol levels can impair the immune system and lead to more frequent infections.
Signs of low cortisol levels (hypocortisolism):
Persistent tiredness: Low cortisol levels can lead to persistent exhaustion and weakness, also known as fatigue.
Weight loss: Unintentional weight loss can indicate a lack of cortisol.
Mood lows: Low cortisol levels can lead to depressive moods, reduced motivation and difficulty concentrating.
Dizziness and shivering: Low cortisol levels can lead to dizziness and shivering.
Muscle weakness: A lack of cortisol can cause muscle weakness and fatigue.
Reduced stress resistance: If your body does not produce enough cortisol, you may be more sensitive to stress.
It is important to note that these signs can be varied and can also be influenced by other factors. If you suspect that your cortisol levels are out of balance, it is advisable to consult a doctor. A professional health practitioner can perform tests and a thorough examination to determine whether your hormone levels are in balance or need adjustment.
Cortisol and melatonin harmony:
The harmonious balance between cortisol and melatonin is crucial. A well-regulated circadian rhythm ensures that cortisol peaks in the morning to prepare you for the day and makes room for melatonin in the evening to induce your sleep.
Cortisol and melatonin management for your well-being:
⚡Stress management: Learn techniques to reduce stress such as meditation, progressive muscle relaxation or mindfulness exercises.
😴 Healthy sleep: Create a comfortable sleeping environment, maintain a regular sleep-wake cycle and promote natural melatonin production.
🏃 Exercise: Regular physical activity supports the regulation of cortisol and simultaneously promotes melatonin production.
🥗 Diet: Choose a balanced diet that supports your hormonal balance.
💊 Customized support: If needed, customized supplements from indyvit.com could help promote harmony between cortisol and melatonin.
Note: In Switzerland, melatonin is banned as a dietary supplement, unlike in other European countries. We therefore use L-tryptophan, which is a precursor of melatonin and can be converted into melatonin by your body. Here is a fascinating article on this topic: Link
The fine balance between cortisol and melatonin is the key to a balanced circadian rhythm and restful sleep. Use your knowledge of these hormones to make conscious choices and promote your health.
Remember that a balanced lifestyle with a healthy diet, regular exercise, sufficient sleep and stress management can help to support your hormonal balance and increase your well-being.
In balance and harmony,
