Melatonin is one of the main hormones that control body functions. It is also known as a sleep hormone. Its release increases in darkness, which allows to fall asleep. It can cause problems such as insomnia when it is secreted slightly. Melatonin supplements are prescribed in cases of extreme insomnia, tinnitus and Alzheimer’s disease. These supplements produced and sold in pill form have no known serious side effects. Since it has antioxidant properties, it is used as an anti-aging supplement.

What is Melatonin?

Melatonin is secreted by the brain and controls the body’s daily rhythm. It is also known as sleep hormone. The production of melatonin secreted by the pineal gland in the brain is linked to the time of day. Its production increases in the dark and decreases in the light.

In addition, its pills that can be taken as supplements are used in many medical conditions such as Alzheimer’s disease, radiation exposure and tinnitus.(1)

What does melatonin do to your body?

This hormone is like the body’s clock, a hormone that tells the body when to fall asleep, when to wake up or eat. It also helps regulate body temperature, hormone levels and blood pressure. People suffering from insomnia or sleep imbalance due to jet-lag boost the hormone level by taking the supplements.

Less secretion of this hormone, which regulates the body’s sleep cycle, causes sleep disorders. Studies have shown that taking melatonin supplements is beneficial for sleep disorder in cases where the body’s biological clock is deteriorated when the person’s sleep-wake cycle is delayed by 3-6 hours.

How is melatonin secreted?

Melatonin secreted by the pineal gland works in conjunction with the light perception of the retinal layer in eye. Cells that detect light in eye signal the state of light to hypothalamus region in brain. These signals are then sent to pineal gland, and hormones are secreted.

In the dark, the secretion of this hormone increases, and at the same time, some changes that promote sleep, such as decreasing body temperature and decreasing respiratory rate, occur. Melatonin levels are low during the day.

Benefits of melatonin

Apart from sleep disturbance problems, melatonin is also used in different areas:

  • It is used as an antioxidant.
  • It is known to have an effect that strengthens the immune system and reduces inflammation, but studies are ongoing on how the process works. (2)
  • With its antioxidant properties, it prevents damage to cells and protects eye health.
  • It regulates fat cells.
  • It has a protective role in neurological degeneration disease and acute pancreatitis.

Causes of melatonin deficiency

Under-secretion of the melatonin hormone leads to deficiency. This condition is known to affect many conditions, from sleep disturbance to psychological disorders, such as:

  • Insomnia: Lack of sleep
  • Jet lag: Insomnia due to time difference in flights between countries
  • Delayed sleep phase syndrome: The body’s daily cycle is too long
  • Sleep disturbances in people working day and night shifts are known to be caused by a deficiency of melatonin.

Melatonin deficiency treatment

When melatonin is not secreted enough, sleep disorders occur. The solution is to take supplements. These supplements are effective in improving sleep rhythms and are used as preventive and supportive in other disorders.

Melatonin pills are preferred more because they have less side effects than sleeping pills. Nevertheless, a doctor should be consulted before use, and any other underlying cause of insomnia should be investigated.(3)

Melatonin hormone is released at most between 23.00 and 5.00 at night and requires a dark environment for its secretion. Sleeping too late and getting up late can also cause sleep disorders. Therefore, taking care to sleep especially during these hours and not sleeping in the day light environment can prevent melatonin deficiency. In order to avoid this problem in children, care should be taken to establish a sleep pattern.

Melatonin and depression

Failure to sleep adequately and quality sleep can lead to consequences such as fatigue, weakness and depression. Melatonin pills are used to regulate the body’s daily rhythm in people experiencing these symptoms.
