Mélatonine : qu'est-ce que c'est et à quoi sert-elle ?

Melatonin is a natural hormone that is essential for regulating the sleep cycle. Découvrez ce qu'est la mélatonine, à quoi elle sert et comment elle peut vous aider à mieux dormir de manière naturelle et sûre.

What is melatonin?

Melatonin is a hormone produced naturally by our bodies. It plays a key role in regulating sleep and wake cycles.

It is synthesized by the pineal gland, located in the brain, and its production depends directly on exposure to light: when night falls, the body begins to release mélatonin to prepare for bed; at night, its levels decrease, signaling that it is time to recover.

When to take mélatonine?

Mélatonin should be preferred in the evening, about 30 to 60 minutes before bedtime. Its aim is to reinforce the body's natural signal that it is time to sleep, by helping to synchronize the circadian rhythm.

It is important to point out that melatonin is not a sleep aid. Its function is to regulate the biological cycle, and not to provoke an immediate somnolence.

Its effectiveness is reinforced when it is combined with good home hygiene habits - such as keeping regular hours, avoiding bright lights before bed and creating a calm, dark atmosphere in the bedroom.

The benefits of melatonin

The benefits of melatonin are linked to improving sleep quality and balancing the body's natural cycle. Among the main :

  • Facilitates falling asleep and reduces the time needed to fall asleep;

  • Improve the quality of the shampoo, favoring a deep and replenishing bath;

  • It can help in the event of a low level of insomnia or a time difference;

  • Ne provoque pas de dépendance ni de somnolence excessive durant la journée ;

  • It acts as a natural antioxidant, contributing to overall well-being.

Used correctly, melatonin is a safe and effective aid for those who want to sleep better and maintain a balanced sleep cycle.

What is the recommended dose of melatonin for adults?

The recommended doses of melatonin vary according to age, purpose and individual sensitivity.
In general, adults should take between 0.5 mg and 5 mg a day, 30 to 60 minutes before bedtime.

It is advisable to start with the lowest dose and adjust it only on medical advice in order to obtain the best results.

Is mélatonine safe in the long term?

Here, mélatonin is safe, provided that it is used responsibly and, ideally, under medical supervision.
Current studies show that it does not cause dependence and does not interfere with the body's natural production.
However, its prolonged use should be evaluated by a health professional, especially for people suffering from chronic illnesses, women who are ill or allaiting, or those taking other medications.

Optimize your wardrobe with adapted mats

Although mélatonin helps to regulate the sleep cycle, the quality of sleep also depends on the environment and the mattresses on which we sleep.
