If you are a "night owl" and prefer a nocturnal life – that's one more reason to wonder how healthy is your lifestyle. In the journal Molecular Psychiatry published the results of a study conducted in the United States. It turns out that the habit of watching TV at night can bring a man to globalizatsii.

Your experiment, neuroscientists at Ohio state University put on the hamsters. One group of rodents living in a standard diurnal cycle: 8 hours in complete darkness and 16 hours in normal daylight. The other - the same 16 hours in daylight. But "night" time, in contrast to the first group, not in the dark and in low light as from the light of a running TV in a dark room. These hamsters suffered. After four weeks mode in "TV included" the rodents began to show obvious signs of depression, was lethargic, didn't respond to the usual motivators, refused treats, for example.

 

The behavior of hamsters, as scientists have found, is due to the arising in their brain changes. In rodents that were exposed to dim light at night activated protein (known as tumor necrosis factor TNF). It increased concentration and provoke destructive changes in the psyche.

What is significant: the same dependence on the protein exists in humans. Scientists believe that constant exposure to artificial light at night plays a key role in increasing the rate of depression among people. However, this problem can be successfully fought.

"Good news for people who are late watching TV and computer, that can remove the negative effect of being in conditions of dim light, just returning to a normal daily routine," - said the head of research, doctoral student at the Department of neurology Tracy bedrosian.

For reference:

Depression — a mental disorder characterized by depressed mood, loss of the ability to survive, thought disorder, motor retardation. When depression is reduced self-esteem, there is a loss of interest in life and usual activities. In some cases, a person suffering from it, may begin to abuse alcohol or other psychotropic substances. Depression affects 10% of the population over the age of 40 years, of which two-thirds were women. In two thirds of cases of depression were key factors of external influence.
