Are you sleep deprived? Be careful because, according to a recent study, you would be more prone to heart disease, Alzheimer’s disease and damage to your immune system.
We can never say enough, a good and long sleep is the key to good health. And this is confirmed once again by a recent study, the results of which were published in the Journal of Experimental Medicine and transmitted by daily mail. According to her, sleeping only six and a half hours a night could have serious consequences for the body.
To reach this conclusion, researchers at the Icahn School of Medicine in New York recruited 14 adults around the age of 35. They reduced the normal length of nightly sleep by 1.5 hours over six weeks and found that each had higher levels of inflammation.
“The key message from this study is that sleep reduces inflammation and lack of sleep increases inflammation.”said Dr. Filip Swirski, a cardiovascular expert. “In the subjects who underwent sleep restriction, the number of immune cells circulating in the blood was higher. These cells are key players in inflammation.”he added, noting that too much inflammation was linked to heart disease and Alzheimer’s disease.

permanent changes in DNA
At the same time, the scientists also noticed that reducing their sleep habits caused permanent changes in the DNA of certain cells. This would have the consequence of accelerating the aging of the immune system.
As a reminder, official guidelines state that adults need between seven and nine hours of sleep each night. In the past, lack of sleep has been repeatedly associated with a higher chance of many diseases, including heart disease, type 2 diabetes, and obesity. It can also affect concentration and therefore lead to poor learning in school or increase the risk of accidents at work or when traveling.
