Can sleep make us sick or not?

I've never heard of this. I always sleep deprivation. And this makes me a frequent headache. I became lazy to work, because of drowsiness.

Well obviously I think that not having enough sleep would not be good times. It could really have different effects on people I would think. I would believe anything anymore, because the lack of sleep is really something that really does have a lot of interesting things that lead to some bad things. This is why I try to get some sleep, to avoid as many health problems that I can. Still, that is quite interesting to say the very least. To think that the lack of sleep leads to heart disease, never heard of that but I am really not surprised about that. Of course, there are other reasons why you should get enough sleep. Still this just puts another reason on top of the list of many. So yeah I would believe lack of sleep can lead to many problems.

well I think that sleeping more than 8 hours is not good because sometimes i feel from myself too that when I sleep more than 8 hours my heart is not in good condition and also I have a hard breathing so I guess sleeping 7 hours in enough for me or 6 hours.
