The scientist still couldn’t find a solid connection between oversleeping and diabetes, but they suspect something. It’s possible that oversleeping is “indicative” of another health condition that makes people more at risk of diabetes.
Another thing that should be noted is that the increased risk could also be found in people who sleep for less than 5 hours a night.
Heart Diseases and Stroke
When it comes to how too much sleep affects the body, stroke is another concern.
In one study featured in the journal of American Heart Foundation (AHA), researchers found out that people who sleep for more than 10 hours each night are 56% more at risk of dying because of stroke.
Additionally, participants who overslept are 4% more at risk of dying due to cardiovascular diseases.
This study by the AHA reviewed 74 studies with more than 3 million participants.
Once again, the solid connection between oversleeping and stroke and heart diseases has not been established yet.
However, scientists think that is has something to do with metabolic and endocrine functions.
Most people already know about the possible effects of sleep deprivation on fertility. But what about oversleeping?
One research analyzed the sleeping habits of 650 women before undergoing the IVF procedure or the in vitro fertilization. They found out that moderate sleepers have a higher pregnancy rate than those who slept for more than 10 hours each night.
Now, let’s discuss how too much sleep affects body weight.
While there’s no definite connection between weight gain and oversleeping, the results of one study show that people who sleep more are also more prone to obesity. This is in comparison with those who sleep between 7 to 9 hours per night.
One could assume that the reason behind it is the lack of exercise. After all, a person who sleeps more has less time to work out.
However, the study has also taken physical activity into account and the results didn’t change. Moreover, they also considered the participants’ food intake.
Possible Causes of Oversleeping
Often, we wake up when we’re already well-rested. Experts even say that if we stick to a certain schedule, we can wake up easily without the help of an alarm clock.
As mentioned earlier, if you regularly need more time to sleep than the benchmark 7 to 9 hours, there could be some problems.
Too much sleep affects the body, but what’s causing it?
- Hypersomnia. The condition which makes it hard for a person to stay awake, hypersomnia is the opposite of insomnia.
- Obstructive Sleep Apnea. A person with obstructive sleep apnea or OSA could wake up dozens to hundreds of times a night. Each time they wake, they are struggling to breathe. What happens is that when they sleep, their throat muscles relax, collapsing the tissues and blocking the airway. On the other hand, OSA could also happen when the tongue falls back in the throat, blocking the airway.
- Bruxism. This is a condition wherein the person grinds their teeth during sleep.
- Restless leg syndrome. This brain disorder gives the person an overwhelming and sometimes uncomfortable urge to move their legs while they are resting.
It’s important to understand that how too much sleep affects the body also depends on the cause. If you experience any of the conditions above, don’t hesitate to seek medical help.
