Sleep is a benefactor, almost all of us love it. Indeed, considering people’s health, sleep has a very important place. When we don’t get a good sleep, that day is very bad and we can be irritable.
There are many methods of quality sleep, one of which is the absence of light in the environment you sleep in. In fact, researchers at the University of Northwestern Medicine have revealed that, according to a new study, the presence of light during sleep can have a very bad effect on your health, beyond quality sleep.
What happens if we keep light in the sleeping environment persistently?
Scientists at Northwestern Medicine have discovered evidence that even small amounts of light can affect your cardiovascular balance while you sleep and increase insulin resistance when you wake up. This means the risk of high blood pressure and diabetes.
Professor of sleep medicine Dr. “The results of this study show that exposure to room lighting, even for just a single night, during sleep can disrupt glucose and cardiovascular regulation, which are risk factors for heart disease, diabetes, and metabolic syndrome,” says Phyllis Zee.
Diabetes and risk of high blood pressure
Dr. “It’s important for people to avoid or minimize the amount of light exposure during sleep,” says Phyllis Zee. The heart rate generally decreases at night while we sleep and rises in the morning when we are exposed to sunlight, and our nervous system is activated according to the secretion. But the same effect can occur when we are exposed to light during sleep.
Co-author of the study, Dr. Daniela Grimaldi says, “Even if you’re asleep when the light is on, your autonomic nervous system kicks in and that’s bad. Generally, along with other cardiovascular parameters, your heart rate is lower at night and higher during the day.” This can cause your body to be unable to use the glucose in your bloodstream for energy and the pancreas to send more insulin to the body to compensate, which over time can lead to Type 2 diabetes
So what should we do for healthier sleep?
To improve the quality of your sleep and have a healthier metabolism when you wake up, be sure to turn off all the lights and TV the next time you sleep. Or even better, buy a sleep mask and go completely dark. make sure you sleep in an environment.The key point here is the eyes. For this reason, no light should enter your eyes. Rest assured your body will be thankful for it.
In addition, going to sleep, especially between 22.00 – 23.00, is described as the ‘healthiest hour’ according to scientists. A large-scale study on this subject shows that sleep hours have an effect on heart diseases and that these time zones are the healthiest hours. In addition, taking care to go to bed and wake up at the same times every day and getting 7 to 9 hours of sleep a day for adults is also a critical point, according to scientists.
