It may be rather difficult to say someone is sleeping too long or not because everyone’s condition is different. In addition, there is also no definitive figure about how long we should sleep. But according to the study, most adults need to sleep between 7-9 hours every night so that their bodies really feel rested.
Therefore, in this article we set that the duration of sleep to normal is about 9 hours. If more than that, there may be many dangers and diseases that will lurk if we sleep more than the standard time of sleeping parents. Here are some risks or dangers of sleeping too long:
Here Sleep Dangers Are Too Old For Health
1. Sleeping too long can increase the risk of depression
In a study using twin adults, researchers found that long sleep duration increased the risk of someone experiencing symptoms of depression. Study participants who slept between 7-9 hours a night had a 27% chance of experiencing depressive symptoms, while those who slept over 9 hours had a 49% chance.
2. Sleeping too long can cause brain damage
A 2012 study found that among elderly women who sleep too much (or too little) over a 6-year period may worsen brain function. Women who sleep more than 9 hours each night (or less than 5 hours) show changes in their brains equivalent to two years of aging.
3. Sleeping too long can affect the level of fertility (complicate pregnancy)
A team of Korean researchers in 2013 analyzed the sleeping habits of more than 650 women undergoing in vitro fertilization. They found that the highest pregnancy rates among women were obtained from women who slept 7-8 hours each night and the lowest pregnancy rates were found in women who slept 9 to 11 hours each night.
4. Sleeping too long may increase the risk of diabetes
In a small study from Quebec, researchers found that people who slept more than 8 hours a night over a 6-year period had a 2x greater chance of developing type 2 diabetes or impaired glucose tolerance than people who slept between 7-8 hours each night.
5. Sleeping too long can cause obesity
In a Quebec study for a period of 6 years, researchers found that sleeping too shortly or longer could increase the likelihood of obesity by 25% compared with those who slept 9-10 hours a day.
6. Sleeping too long may increase the risk of heart disease
In an American College of Cardiology research presentation in 2012, sleeping 8 hours or more every night may increase the risk of heart problems. The researchers analyzed data from more than 3,000 people and found that people who slept for too long had 2 times the risk of angina and 1.1 times the risk of coronary artery disease.
7. Sleeping too long can cause death
In a review of 16 different studies, researchers found an increased risk of death among both young men who slept too short and too long. Sleeping more than 8 hours each night can increase the likelihood of death 1.3 times greater. Apart from the bad effects caused by too long sleep over.
