Two hormones, two worlds
Cortisol and melatonin are hormones that play key but opposing roles in regulating circadian rhythm. Cortisol, called the stress hormone, naturally reaches its highest level in the morning, mobilizing the body for action. Melatonin, the sleep hormone, begins to be released in the evening as darkness falls, signaling that it’s time to rest. When these two hormones are in balance, the body functions efficiently: we sleep well, we have energy in the morning, and our metabolism works properly. Unfortunately, modern lifestyle often leads to disruption of this rhythm.
Chronic stress – the main saboteur of sleep
Long-term stress causes cortisol levels to remain too high throughout the day and sometimes even in the evening. This condition results in difficulty falling asleep, waking up at night and feeling tired despite a good night’s sleep. Moreover, high cortisol in the evening inhibits the production of melatonin – the body does not receive the signal that it is time to calm down. As a result, the circadian rhythm is disrupted, which may lead to the so-called “rhythm reversals” – sleepiness during the day, arousal in the evening.
When disturbed sleep rhythm leads to weight gain
Insufficient sleep, especially deep sleep, causes an increase in the level of ghrelin (hunger hormone) and a decrease in leptin (satiety hormone), which translates into greater appetite and the tendency to snack. High cortisol further promotes fat storage – especially in the abdominal area – and also increases blood glucose levels, promoting insulin resistance. Sleep disorders are not just a problem of fatigue – they have a real impact on metabolism and difficulties with losing weight.
Symptoms of disturbed cortisol-melatonin rhythm
Many people do not realize that cortisol and melatonin may be responsible for their ailments. Typical symptoms of disrupted circadian rhythm are:
- difficulty falling asleep despite being tired
- frequent waking up at night or waking up too early
- sleepiness during the day and arousal in the evening
- brain fog, irritability, energy drops
- no weight loss effects despite the diet
- craving for sweet or fatty snacks in the evening
How to restore balance naturally?
Rebuilding the circadian rhythm requires, above all, regularity. The most important rules are:
- exposure to natural light in the morning
- avoiding screens (blue light) in the evening
- sleep at regular times, preferably between 10 p.m. and 6 a.m
- relaxation techniques: meditation, walk, bath
- physical activity (but not intense in the evening)
- a diet rich in magnesium, B vitamins and tryptophan
supplements Calivita supporting hormonal balance
Melatonin – natural melatonin in the optimal dose, helps you fall asleep faster and improves sleep quality. Particularly recommended for people with “inverted rhythm” and problems with winding down in the evening.
Rhodiolin – an adaptogen containing Rhodiola rosea, which regulates the body’s response to stress. It helps lower evening cortisol and reduces nervous tension.
Stress Management B Complex – a set of B vitamins that support the nervous system, energy metabolism and the production of neurotransmitters responsible for well-being.
Calcium Magnesium Plus – contains magnesium, which not only calms the nervous system, but also supports muscle relaxation and may facilitate falling asleep.
The role of the HPA axis in circadian rhythm disorders
Cortisol-melatonin balance disorders are closely related to dysfunction of the hypothalamic-pituitary-adrenal (HPA) axis. Chronic stress overstimulates this axis, leading to a constant state of “alarm” in the body. As a result, cortisol stops decreasing in the evening, and melatonin has no conditions for synthesis. Moreover, chronic overload of the HPA axis may lead to the so-called “adrenal burnout”, manifesting itself not only in sleep problems, but also in chronic fatigue, decreased immunity and sensitivity to stress. Therefore, it is worth acting comprehensively – not only supporting the production of melatonin, but also regenerating the adrenal glands and supporting the body with adaptogens, such as Rhodiolinand B vitamins and magnesium, which support the nervous system at the cellular level.
Summary – the harmony of cortisol and melatonin is the key to health
Cortisol and melatonin are not rivals, but rather two partners in the biological rhythm that must act in synchrony. If their cycle is disrupted, the consequences include not only sleep problems, but also difficulty concentrating, depressed mood, weight gain and chronic fatigue. Fortunately, natural supplemental support, sleep hygiene and stress reduction can effectively restore hormonal balance. Preparations Calivitathanks to their quality and synergy of ingredients, can be a valuable support in this process.
