Increases Risk of Depression
In a study conducted in 2014, which involved adult twins as participants, it has been concluded that sleeping longer can make an individual at higher risk of showing depressive symptoms. Those who slept in a duration of seven to nine hours, which is the recommended amount of sleep, showed only 27% of the symptoms of depression. On the other hand, those who slept beyond nine hours show 49% of heritability of the symptoms of depression.
Affects Mental Health
In 2012, in a research that involved elderly women as participants, the effect of oversleeping and under-sleeping were explored. Based on the conclusion of the study, those who sleep more than nine hours or less than five hours, showed changes in the functioning of the brain. These changes are similar to what women who are two years older would show. Meaning, it speeds up the aging of the brain.
Heightens Possibility of Infertility
In a research completed by a Korean team in 2013, 650 women who are undergoing in vitro fertilization have been involved as the subjects. From the said study, the conclusion revealed that those who slept more than 11 hours have lower risks of getting successfully pregnant. Nonetheless, many experts were quick to claim that this may be a bit more challenging to prove as there are many other factors that could come into play.
Increase Risk of Diabetes
In Quebec, a small study has been conducted to explore the negative health effects of oversleeping. Based on the findings, the conclusion was that those individuals who had more than eight hours of sleep for a period of more than six years were more likely to have type 2 diabetes compared to those who have just the right amount of sleep.
In the same study as above, the weight of Quebec adults were studied for a period of six years. They found that people who tend to sleep beyond nine hours or less than seven hours are at higher risk of gaining unwanted weight. The likelihood of gaining up to 5 kilograms is 10% among adults who had less or more than the recommended hours of sleep.
Affects Heart Health
In 2012, during a meeting of the American College of Cardiology, one research presented has revealed that people who sleep beyond eight hours are more likely to experience cardiovascular problems. The findings of the research were based on 3,000 participants. The study specifically revealed that those who oversleep are two times more likely to suffer from angina and 1.1-times likely to have coronary artery disease.
This is perhaps the most serious among the problems that are associated with oversleeping. Sixteen various researches were further explored in 2010. The conclusion was that sleeping beyond the recommended duration can lead into death, with causes varying form one study to the other. The studies analyzed have a total number of 1,382,999 participants. The risk of death is 1.3-times higher among people who sleep too much.
