While some adults experience insomnia as a sign of depression there is a percentage of adults, as well as children and teens, who experience oversleeping due to this condition. If you are neglecting or unaware of the fact that you are suffering from depression, oversleeping can be a sign that you shouldn’t ignore.
Your heart might be the cause.
One of the signs that you might be suffering from a heart-related disease can be oversleeping. This also includes daytime sleepiness. While you might be feeling tired and exhausted, it might not be because you have worked a lot. That is why it is not easy to differentiate if your problem with sleeping more then 9 hours in a 24-hour cycle can be related to heart issues.
