Time and again we are warned that too little sleep has a negative impact on our well-being. But even notorious late sleepers put their health at risk. 7 health risks of too much sleep.
People who get enough sleep are healthier and more productive.
Doctors recommend between 7 and 9 hours of sleep to function optimally.
If you regularly miss out on a good night’s rest, sooner or later it will affect how you feel. But even an overdose of sleep is not necessarily recommended: those who constantly sleep too long risk damaging their health.
1.Reduced Memory Performance
A 2012 study of older women showed that too much (as well as too little) sleep worsened their brain’s performance over a 6-year period. Women who slept more than 9 hours per night (or less than 5) showed brain changes as if they had aged an average of two years more.
2.Risk Of Depression Increases
It’s not just chronic sleep deprivation that can make people depressed. Long sleepers also have an increased risk of depression. This is proven by a twin study from 2014. 27 percent of the participants who slept an average of 7 to 9 hours showed depressive symptoms. For those who rested more than 9 hours per night, the figure was 49 percent.
Those who sleep an average of 9 to 10 hours are not doing their figure any good either. Sleep researchers have found out: Those who sleep too long risk weight gain. For six years, the study leaders observed the sleep behavior and weight of their test subjects. The result: long sleepers gained one and a half kilos more during this time than people who allowed themselves seven to eight hours of sleep.
4.Problems Getting Pregnant
Women who want to get pregnant
should pay attention to a balanced sleep-wake cycle. A 2013 study involving more than 650 women who underwent artificial insemination found that those who slept between 7 and 8 hours were most likely to get pregnant. The lowest pregnancy rate was achieved by women who slept between 9 and 11 hours per night.
5.Increased Risk Of Diabetes
Another study found that people who slept more than 8 hours per night were twice as likely to develop type II diabetes than those who slept 7 to 8 hours.
6.Too Much Sleep Is Bad for The Heart
A U.S. study shows that heart problems are much more common in late sleepers than people with the recommended dose of sleep. Sleep researchers evaluated data from over 3,000 people and found that people who got too much sleep were twice as likely to have angina and coronary heart disease.
In 2010, 16 different studies showed that the life expectancy of people who slept too little and those who slept too long was shorter than that of people who slept optimally.
