The study, whose results were published in the journal, "Proceedings of the National Academy of Sciences"Scientists concluded that the body cannot rest properly when the light is strong, which causes a high heart rate. the heart.
The researchers pointed out that even dim lighting from natural or artificial sources during sleep can harm the function of the heart and blood vessels, and increase the resistance of the body. InsulinCells in muscle, fat and liver struggle to absorb glucose from the body.
The researchers discovered that moderate exposure to light caused the body to enter a state of alert, which was accompanied by an increase in the heart rate as well as the force with which it contracts, and the rate of blood delivery to the blood vessels in the body for the flow of oxygenated blood.
Commenting on the study findings, Phyllis Zee, chair of sleep medicine at Northwestern University, said: "The study shows the damages of exposure to lighting during sleep, as it can impair glucose regulation andMetabolism".
The researcher continued: "It is important that people avoid or reduce the amount of exposure to light while sleeping".
Zee added: "In addition to sleep والتغذية And exercise, exposure to light during the day is an important factor supporting health, but during the night even moderate light intensity can weaken the measurements. heart health and endocrine"according to the site "i news" British.
