What is melatonin and how does it affect the body?

Melatonin is a sleep hormone produced in the brain. Its primary function is sleep regulation, but it also plays a role in other biological processes within the body.

The natural production of melatonin depends on light levels. During the day, its levels are low, while at night, as darkness falls, its production increases, sending a "sleep signal" to the body.

Melatonin's role is especially important for the sleep cycle, as it helps the body adjust to changes in the day-night rhythm. It is also associated with stress reduction, slowing down the aging process, and strengthening the immune system.

Melatonin has a significant impact on the body, especially on the sleep process, but its effects are not limited to this alone. Let’s explore how melatonin affects our body:


1. Sleep Regulation

Melatonin is one of the key hormones responsible for regulating the sleep cycle.

2. Biological Rhythms

It influences the body's biological rhythms, adjusting to light exposure and helping the body align with the day/night cycle.

3. Stress Control

Melatonin is often associated with stress reduction, as it lowers cortisol (the stress hormone) levels in the body. It promotes relaxation and helps minimize the negative effects of stress.

4. Slowing Down Aging

Melatonin acts as an antioxidant, fighting harmful free radicals in the body. This process helps slow down aging.

5. Immune System Support

Melatonin strengthens the immune system. Its natural antioxidant properties help reduce inflammation and assist the body in effectively fighting infections.


Is it possible to take melatonin?

As we know, melatonin is naturally produced in our bodies, but certain factors may affect its production. These factors can be related to lifestyle, such as irregular sleep patterns or high stress. Additionally, as we age, melatonin production decreases, which negatively impacts sleep quality. Furthermore, some medications, health issues, or lack of physical activity may reduce hormone production, ultimately leading to sleep problems and lack of energy. Therefore, it is important to maintain a healthy lifestyle and provide our bodies with the best conditions to naturally produce melatonin and support our physical and emotional health.

Melatonin Medication Forms

Melatonin can be taken in medication form, which is available in various doses and forms. Melatonin is available as tablets, capsules, and chewable tablets. Although melatonin can be taken without a prescription, it is very important to follow the doctor’s recommendations to ensure the correct dosage and duration of use. This way, possible side effects can be minimized. Let's review several popular forms of melatonin:
