People who do not sleep in the perfect darkness have an increased risk of developing cardiovascular and oncological diseases, reports RIA Novosti quoting three Russian scientists who conduct sleep studies.
"Now more and more data show that there is a clear link between excessive lighting, especially in large cities, and the risk of developing illnesses, especially cardiovascular and oncological diseases," said the director of the Medical Center Sanja at Moscow State University, Alexánder Kalinkin.
"Now more and more data show that there is a fairly clear link between excessive lighting, especially in large cities, and the risk of disease …
According to this somnologist, each cell in our body contains its own clock. This means that the cyclical nature of some processes in the organism differs from the 24-hour cycle. Therefore, the role of hormone melatonin is very important: synchronize all these processes. Kalinkin explained that light is the main regulator of melatonin production.
Excessive light, which comes from the bright lighting of computers or devices that we usually use at night, "moves the production phase of melatonin in later hours" and causes sleep problems in humans, he explained.
"When we sleep, it not only changes the functioning of functional systems, such as cardiovascular, respiratory, etc., but also the activity of genes, the functioning of certain genes," Kalinkin said.
"Our body was designed to emerge after the sunrise, with the brightness of the sun, because its light again begins our biological clock"
On the other hand, the chief researcher of the Institute of Ecology and Evolution of the Russian Academy of Sciences Vladimir Kovalzon stated that many studies show that people who wake up from the sun have a higher risk of immunity deteriorated and have suffered depression.
"Our body was designed to stand up after the sunrise, with the brightness of the sun, because its light again begins our biological clock," explained Kovalzón. He noticed that electric light differs greatly from solar energy and has no chance of restarting the biological clock.
Mikhail Poluéktov, Head of the Department of Sleep Medicine at the First Moscow State Medical University, also stated that the replacement of the dream with all the activities is contrary to the internal urine of the body.
"Regardless of whether we want to sleep, the cells of our body reach the darkness in the night mode, it's under the control of the genetic mechanism inside each cell. No matter how many times we try to change our usual biorhythms with our behavior, it does not we can do it, "Poluektov said. If a person works at night and sleeps during the day, this leads to disagreement in the processes of his body, the expert is detailed.
After 22:00, when your level is high enough, the optimal conditions for sleepiness are created
"At 21:00 to 22:00 hormone melatonin starts to emerge. After 22:00, when your level is high, the optimal conditions for sleepiness are created. In addition, the rhythm of body temperature is important and begins to change at night: the internal temperature of the body drops and consequently it facilitates the coordination of dreams. This happens after 22:00 hours, "said Poluektov.
The academician emphasized that, according to the World Health Organization, work on night work is associated with cancer risk. He also reported that scientists conducted research in primitive societies, tribes in Africa and South America, and that data showed that time for drowsiness was not determined during the sunrise and sunset, but only by reducing and increasing the body's internal temperature.
They find that sleeping in an environment that is not completely dark means a life-threatening danger
