How does melatonin work?

You have probably heard of melatonin before but do you know what it is or what its function is?

You are in the right place then! In this article, we will be telling you everything you need to know about melatonin and the way it works.

Besides, we will also let you know if it is a good idea to take melatonin as a supplement and in which conditions it will be helpful.

Melatonin is a hormone that can be naturally found in the body.

It contains the pineal gland and it is located above the middle of the brain.

Melatonin is being produced by the suprachiasmatic nucleus and released into the blood.

However, you can find it in the eyes, the bone marrow, and the gut as well.

The hormone is also a medication, most often in the form of a pill.

The way melatonin works

Melatonin is also known as the โ€œsleep hormoneโ€.

The latter is due to the fact that melatonin is responsible for your sleeping pattern.

It works with your circadian rhythm which is your bodyโ€™s internal clock.

Thanks to it, your body knows when it is time to wake up or fall asleep.

Melatonin starts being produced after sundown because of the darkness.

As melatonin levels become higher, you feel less alert.

This leads to sleepiness. Melatonin levels stay high for up to 12 hours – or all night long – until the light of the new day lowers them.

Precisely for this reason, people know melatonin as the โ€œDracula of hormonesโ€ – it gets more active in the dark.ย 

In fact, light suppresses melatonin production.

Therefore there is some advice you may want to follow in order to achieve a good nightโ€™s sleep.ย 

Such are:

  • lower the lights in the whole house two hours before bedtime;
  • stop using electronic devices at least an hour before going to bed – the blue light emitted from their screens confuses your circadian rhythm since it is naturally emitted by the Sun.
