Scientists have explained why it is impossible to sit at the computer before bed
MOSCOW, may 29 — RIA Novosti. Unlimited use of computers and tablets in the evening causes sleep disturbances and knocks circadian rhythms of the body, found by a research group under the guidance of the staff of Harvard University. The study is published in the journal Physiological Reports.
Scientists conducted an experiment in which subjects were asked to spend five evenings in front of the computer and the same for reading books, Newspapers and other printed materials. The study involved both men and women, aged 22 to 28 years.
According to the results, using light-emitting gadgets, such as a computer, phone or tablet adversely affects the speed of falling asleep. So, the participants noted that after the interaction with the electronics, they fell asleep half an hour later than usual. Furthermore, subjects complained of drowsiness and loss of concentration in the morning and too vigorous as in the evening.
Scientists have also found that the use of gadgets suppresses the production of melatonin — the hormone responsible for periods of sleep and wakefulness.
“The data provide more evidence that light-emitting electronic devices have a biological effect on the body,” said one of the authors Jeanne Duffy.
Earlier it became known that sleep disorders are dangerous to health. Scientists from the University of boulder, Colorado, found that only a couple of nights of wakefulness significantly modifies the physiological parameters of the body and can bring down the internal clock more than a hundred different proteins. Scottish experts came to the conclusion that the habit of stay up late can lead to the emergence of mental disorders.
