Melatonin (N-acetyl-5-methoxytryptamine) is a hormone and neurotransmitter that is found in all living beings: people, animals and plants. Melatonin is the body's natural sleep hormone and stimulates sleep and sleep quality. Melatonin is also a powerful antioxidant that boosts the immune system and helps protect body cells and tissues and prevents rapid aging. The production of melatonin improves in the dark, therefore, Melatonin is also know as the “darkness hormone”.

In today's modern society we are all subjected to artificial lighting from smartphones, tablets, TVs and computers. This lighting is clearly suppressing melatonin production.

Where and how is melatonin produced?

In humans, melatonin is produced by the pineal gland. The amount of melatonin is determined by ambient light. The darker the room, the more melatonin is produced. In mammals, its produced by the pineal gland (epiphysis) from tryopfan by including serotonin. The amount of melatonin varies during the day and influenced by the light - the production level increases in the dark and is at its highest at night.

When is melatonin produced?

The production of melatonin improves in the dark, therefore, Melatonin is also called the “darkness hormone”. A natural production of melatonin takes place in the evening, where the eyes are surrounded by natural darkness - where the eyes are not exposed to either natural or artificial lighting.

The use of artificial light in the evening and at night reduces the formation of melatonin production and causes disorder in many of the body´s functions and is considered by scientists to be the cause of the increased incidence of sleep problems, but also breast cancer and other cancers in industrialized countries.

What affects the production of melatonin?

In our modern world, we are all too often exposed to artificial lighting from computers, smartphones, tablets, and televisions. But even light sources of indoor lighting are artificial.

Very often we are exposed to artificial light during the night, thereby creating an imbalance in our natural circadian rhythms by inhibiting the natural production of melatonin.

Technically, it is the blue light of the light spectrum (446-447 nanometers) that inhibits the production of melatonin. Health Eyewear blocks the blue light up to 530 nanometers, which generates that the body produce melatonin and ensure a good sleep and strengthened your immune system.

With Health Eyewear you can easily watch TV, work on the computer, use your smartphone and not disturb your production of melatonin.

Melatonin and sleep

Children and adolescents need many hours of sleep per day (10-15 hours), while adults and older people can get by with significantly fewer hours of sleep per day (5-10 hours). Sleep needs vary from person to person and depends largely on the individual's melatonin production. The production of melatonin is highest in 5-10 year-olds, then the ability to produce melatonin reduces. 

How long the body produces melatonin?

Over a day, the body can maintain a maximum production of melatonin 12 hours straight. Usually lasts a maximum production of melatonin in adults lasts 9-10 hours straight per day.
