Melatonin: what it is and what it is for

Melatonin is a natural hormone that is essential for regulating the sleep cycle. Find out what it is, what it's good for and how it can help you sleep better naturally and safely.

What is melatonin?

Melatonin is a hormone that is naturally produced by the body and plays a fundamental role in regulating sleep and wake cycles.

It is synthesized in the pineal gland, in the brain, and its production depends directly on exposure to light: when it gets dark, the body begins to release melatonin, preparing for sleep; when it gets dark, the levels decrease, signalling that it is time to wake up.

When to take melatonin

Melatonin should preferably be taken at night, 30 to 60 minutes before going to bed. Its aim is to reinforce the body's natural signal that bedtime has arrived, helping to synchronize the circadian cycle.

It is important to remember that melatonin is not a sleep medication. Its function is to regulate the biological cycle, not to cause immediate somnolence.

Its effect is most effective when combined with good sleep hygiene habits - such as keeping regular hours, avoiding blue light before bed and creating a quiet, dark environment in the bedroom.

Benefits of melatonin

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

  • Facilitates the onset of sleep and reduces the time needed to fall asleep;

  • Improves the quality of sleep, favoring a deep and restful rest;

  • It can help with mild insomnia or jet lag;

  • It does not cause dependence or excessive somnolence during the day;

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

When used correctly, melatonin is a safe and effective ally for those looking 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 going to bed.

It is recommended to start with the lowest dose and adjust it only under medical supervision, to guarantee the best results.

Is melatonin safe in the long term?

Yes, melatonin is safe as long as it is used responsibly and preferably under professional supervision.
Current studies indicate that it does not cause dependence or interfere with the body's natural production. However, prolonged use should be evaluated by a health professional, especially in people with chronic illnesses, women who are pregnant, lactating or taking other medications.

Boost your rest with the right mattress

Although melatonin helps to regulate the sleep cycle, the quality of rest also depends on the environment and the mattress where we sleep.
A quality mattress guarantees comfort, body alignment and an optimum temperature, enhancing the effects of melatonin.
