Do not Underestimate Your Sleep Every Night, Because Lack of Sleep Proves Not Good For Your Heart Health
Those who sleep less than 7 hours each day, including naps, are at higher risk for cardiovascular disease. And for those who sleep less than 5 hours each day, including the nap, have a 2x risk for heart attack, or stroke, according to a study conducted by researchers at the Faculty of Medicine West Virginia University (WVU).
The biggest risk is for those who are over 60 who sleep less than 5 hours per day. The risk of these bad habits can increase your risk of developing the cardiovascular disease by 3x.
The study, published in the journal Sleep, was led by Anoop Shankar, MD, Ph.D. (Associate Professor at WVU) analyzed data from 30,000 adults. They conclude that the duration of a person’s sleep affects endocrine function and metabolism. Lack of sleep can cause high blood pressure, decreased glucose tolerance, decreased insulin sensitivity.
Do not Lack Sleep
A separate study, also published in the journal Sleep, looked at 142 adults who for 5 consecutive days (working days). The result is that they have the ability to react more slowly, and have difficulty concentrating.
However, adding one or two hours of sleep in the morning after a period where bedtime is limited to only 4 hours per night has a very positive effect on reducing symptoms associated with lack of sleep.
David Dinges, Head of Sleep and Chronobiology at the University of Pennsylvania School of Medicine, said: “An extra bedtime of one to two hours in the morning after a certain period in which a person experiences sleep deprivation has a good benefit in reducing the negative effects of sleep deprivation. ” But make no mistake. This does not mean that you can go on to sleep by assuming that an extra one or two hours per week is enough to cover everything. Because the chronic lack of sleep habits can not be recovered just by adding one or two hours of sleep. Even maybe an extra 10 hours per week would not be enough. Nothing can replace good habits, including in terms of sleep discipline.
In addition, work performance and brain responsiveness became significantly slower when subjects were limited to 5 hours of sleep in a row, though on weekends they were given an additional 1-2 hours of sleep as described above.
