Scientists have found that led and halogen lamps are dangerous to health, because they reduce the production of melatonin - the hormone which regulates the biological clock, but also has immunostimulant and antitumor activity.
Long known that artificial white light, which in reality is blue, suppresses the secretion of melatonin. It is dangerous for health, because this hormone is responsible for the biological clock exerts a strong influence on the immune system and in addition prevents the development of in the body of tumors. The degree of harmful impact of artificial white light on human health is increasing and is associated with widespread radiating his lamps in living rooms, on the street, in offices, stadiums, etc.
In the study, researchers examined how strongly inhibit the secretion of melatonin in various types of lamps. The unit was adopted the result of the sodium lamps with high pressure. Compared to standard halogen lamps 3 times stronger than inhibit the formation of melatonin, and led lamps reduce the secretion of this useful hormone is more than 5 times more active.
Referring to extracted results, the researchers urge the governments of the countries, is not indifferent to the welfare of its citizens, to amend legislation, which would restrict the penetration of harmful led and halogen lamps.
