Which is MORE harmful, to lack sleep or to oversleep?

depends how long! lack of sleep looks older and over sleep looking tired or feels tired.

Hi selece! You're still here! You haven't disappeared yet! I'm so glad! I don't believe that too much sleep can harm you really! But, not enough sleep is bad! I should know! It messes you up in alot of ways. It does dull your senses, makes it hard for you to think, to function, to concentrate, and I believe it even can weaken your immune system over time. I say this because I have insomnia and it is a proven fact that no sleeping does so harm to the body. I hav never heard that sleeping too much does anything serious to a person's body, at least not that I know of medically speaking. I guess you could say that it would decrease your life span because you sleep your life away???lol NO, I'M KIDDING!!! But, I will ask my doc when I speak to him. I wish I knew because I saw him today! Will be talking to him in a few days for test results so will get back to you if I find out the answer!

I don't know which is worse. I know over sleeping you feel really badly like you are sick and have body pains and headache from over sleeping. Not enough however, has many different affects to the bady, you are sluggish, very tired, can't think clearly, and many more. Have a terrific day selece.

i will never have to worry about oversleeping.i don't believe that it could do that but who knows.

I don't know for certain but it would seem to me that a lack of sleep is more harmful to your health. Your brain needs to go through all of the stages of sleep before it gets the deep sleep that it needs. The amount of sleep you need varies though. I get by fine on six hours per night...more than eight makes me feel sluggish.

Lack of sleep is more harmful than over sleeping, besides how do you know you are over sleeping? The body only sleeps as much as it needs so if you don't sleep enough it is not good for the health.

i would consider that lack of sleep is worse than over sleeping. driving while sleep deprived is like driving drunk and can give the same consequences from the police. sleep deprevation causes slow reflex time and a myriad of other issues.

i dont know!hhehehe i think it's both, so we better not do it..hehehe but i really cant help over sleeping sometimes!:) i always feel sleepy and everytime, i would really sleepy when i feel like one. I love sleeping.. especially during weekends and when i dont have so much things to do, i would definitely sleep and snore for as long as i like!hehehe if there are people who loves eating, i am the kind who loves sleeping!:)

I haven't heard about oversleeping decreasing one's life span. Anyway, I'm not sure which one is more harmful to us but I'd go with lack of sleep. Lack of sleep drains our energy, makes us weak and could even make us sick. Having less hours of sleep than what our body needs would make us function less or not function at all, physically, emotionally and mentally. We'd be moody, irritable and angry than we normally do therefore affecting our work and other as well.

Of course it's Lack of Sleep. I love sleeping so if I do not get enough sleep.. I'll get grouchy.. cranky.. irritable and etc. So yea.. lack of sleep is harmful to me and my family and friends. I never hear of that rumor before. I think everything in life must be in moderation. To me, I'll be happy with 8-10 hours of sleep.

Oversleeping is really harmful for your body.. If you sleep more, you will feel tired most of the time. Don't sleep more than 7 hours. keep posting take care and have fun..

Both are harmful but lacks of sleeps is more harmful. You feel dizzy,sleepy,weak,out of focus when lack of sleep but oversleep makes you kinda blur and lazy.
