Melatonin – characteristics, properties and application

Melatonin is a hormone that is synthesized in the brain by the gland called the pineal gland. First of all, it has a significant impact on the regulation of circadian rhythms of the body. This means that too low concentration of melatonin in the blood may result in sleep disorders, continual fatigue, irritability, impaired concentration and apathy. Of course, there are both modifiable and non-modifiable factors that cause the organism to decrease its secretion. How to improve the quality of sleep in a healthy way?

  7. What is melatonin?

Melatonin is an organic chemical compound. This is a hormone synthesized by the human body, specifically the small gland located in the brain – the pineal gland. The main function of melatonin is to coordinate the work of the biological clock. Interestingly, it is synthesized by our body only during the night hours, which is why it is often called the hormone of darkness.

  1. Melatonin properties

Melatonin is primarily responsible for the regulation of circadian rhythms, including sleep and waking. The proper concentration of melatonin in the blood positively influences the acceleration of falling asleep and significantly reduces the number of awakenings during the night. People who have sleep related problems say that taking melatonin significantly improves the comfort of night rest.

It turns out, however, that in addition to the aforementioned properties, melatonin also has a number of other health benefits, among others

– slows down the aging process of the body, mainly thanks to the neutralization of free radicals,

– improves the overall immunity of the body,

lowers blood pressure,

– improves the functioning of the heart,

– helps in the treatment of depression,

– may limit the incidence of various types of cancer.

  1. Factors affecting melatonin secretion disorders

The production of melatonin by the pineal gland largely depends on the intensity of light.In the dim light, when it is quite dark, the concentration of melatonin in the blood is greatest.It is considered that the peak of melatonin synthesis falls into the night hours – between 2400 and 0300. The situation is the opposite when exposed to light.When it is clear, melatonin production is halted.Another factor affecting the secretion of melatonin by the body is age. Production of the discussed hormone decreases with age, which causes considerable difficulty in falling asleep and insomnia.

  1. How to use melatonin?

There is a large group of people suffering from problems related to sleep. Unfortunately, they often reach for sleeping pills, which in most cases do not improve sleep quality at all. After taking such tablets after waking up, you can often feel tiredness, irritability and visible problems with concentration and reflexes.Insomnia can be a deeper disorder, associated with disturbed hormone production by the body. To speed up falling asleep and to significantly improve the quality of sleep, it is worth to supplement melatonin. In addition to improving sleep, it will significantly improve general well-being and reduce the number of awakenings overnight. Of course, melatonin should only be used by people struggling with insomnia and sleep disorders.There are no indications for its use by people without such problems.

The dose of melatonin to be taken should be determined individually. However, it is usually recommended to take 1-3 mg melatonin per day.In some cases, it is recommended to take up to 5 mg.In order to regulate the circadian rhythms of the body, it is recommended to take melatonin regularly, about an hour before bedtime. What is equally important, it is not advisable to stop using the day-to-day treatment, but gradually reduce the doses.
