I can sleep a whole day especially in summer

no i cant sleep for the whole day

I do not. it is impossible.Only somniphilics do it.I don't know about those who suffer from jet lag?

I agree with you. Some of the people I know can sleep for 24 hrs straight, believe me they don't stand up to drink water or to go to the bathroom. When they wake up, they feel awkward, heavy and their heads are aching. You supposed to feel energized because you get a lot of rest but you're not. If we give give our body too much than what is just right, it is bad.

Yeah. if my week is too much crowded and i did not adequete sleeping I spent the whole weekend sleeping. it looks like the human body has a defined number of hours to sleep. so whatever the consequebnces I have to sleep.
