Energy saving lamps are dangerous to health

 

Abraham Haim at the University of Haifa and his colleagues for several years has been studying the link between sleep mode and the influence of external stimuli on human health. In the study, it was found that the direct influence of the light of fluorescent lamps in the night time contributes to the development of breast cancer.

Mostly at risk are people with compromised internal "time" mechanisms, and in particular, those who are awake at night at work.
By the way, the world health organization (who) in December 2007 included people working in the night shift in a group with an increased risk of cancer.

Circadian rhythms, scientists say, is associated not only with the cycles of sleep and awakening, but also applies to changes of other parameters: body temperature, level of hormone production, metabolism. Among the hormones produced during sleep, it is very important hormone melatonin, says MC.
Melatonin releases from the pineal gland (pineal gland) in the brain. He takes part in the establishment of a circadian (circadian) rhythm, affecting the secretion of other hormones. And in addition, participates in the regulation of blood pressure, digestion, a number of other processes and, most importantly, has an antitumor effect.

During the day, an adult produces about 30 mcg of the hormone. Night its concentration is 30 times more than during the day, but peak activity of the synthesis have two hours of the night. It is here that scientists discovered the danger of the fluorescent lights: if the person is in a bright place, melatonin significantly reduced. And this directly increases the risk of cancer. And energy-saving lamps, emitting blue light with a wavelength of about 460 nanometers amplify this effect.

However, the scientist noted, his study does not mean that the replacement of incandescent bulbs with eco-friendly fluorescent light bulbs leads to an increase in the number of cases of breast cancer. According to him, all this is only a theory, which needs careful scrutiny.
