People who do not sleep in total darkness have an increased risk of developing cardiovascular disease and oncology, reports RIA Novosti, citing three Russian scientists who conducted a study of sleep.
"Now, more and more data shows that there is a clear connection between excessive lighting, especially in large cities, and the risk of developing diseases, especially cardiovascular disease and oncology," said director of the Dream Medicine Center at Moscow State University Alexánder Kalinkin.

According to the somnologist, every cell in our body contains its own clock. That is, the nature of the cycle of several processes in an organism is different from a 24 hour cycle. Therefore, the role played by the hormone melatonin is very important: synchronize all these processes. Kalinkin has explained that light is the main regulator of melatonin production.
Excessive light comes from bright computer light or gadgets that we usually use at night "replacing the phase of melatonin production in later hours" and causing problems with sleep in people, he explained.
"When we sleep, it not only changes the functioning of functional systems such as cardiovascular, respiratory, etc., but also genome activity, certain gene activity," Kalinkin said.
"Our bodies are designed so that we wake up after sunrise, with the sun's brightness, because the light reignites our biological clock"
In turn, the chief researcher of the Institute of Ecology and Evolution of the Russian Academy of Sciences, Vladimir Kovalzon, has stated that many studies have shown that people who wake up before sunrise, have a higher risk of having poor immunity and suffering from depression.
"Our bodies are designed so that we wake up after sunrise, with the sun's brightness, because the light reignites our biological clock," explained Kovalzón. He has noted that electric light is very different from the sun and does not have the ability to restart biological clocks.
Mikhail Poluéktov, head of the sleep medicine department of the First Moscow State University of Medicine, also stated that replacing dreams with all kinds of activities is contrary to the internal workings of the body.
"Regardless of whether we want to sleep or not, our body's cells in the dark go into night mode, this is controlled by the genetic mechanism that is in each cell. No matter how many times we try to change the biorhythms of our habits with our behavior, we don't will be able to do it ", has maintained Poluéktov. If someone works at night and sleeps during the day, which causes disagreement in his bodily processes, experts have detailed.
After 22:00, when your level is high enough, the most optimal conditions for sleeping are created
"At 9:00 a.m. to 10:00 p.m. the secretion of the hormone melatonin begins. After 10:00 p.m., when your level is high enough, the most optimal conditions for sleep are created. In addition, the rhythm of body temperature is important and begins to change at night : The body's internal temperature drops and consequently this facilitates the blessing of dreams, which occurs after 10:00 p.m., "said Poluéktov.
Academics have shown that, according to the World Health Organization, night shift work is associated with cancer risk. In addition, he reports that scientists have carried out research in primitive societies, tribes in Africa and South America, and that data shows that the time to fall asleep is not determined at sunrise and sunset, but only with a decrease and increase in internal body temperature.
They revealed that sleeping in an environment that is not completely dark brings life-threatening dangers
