we should sleep 8 hours a day or more.what do you think?

My doctor says that we should sleep only for eight hours per day because if we sleep too much then our body will feel very tired as if laziness has taken over so I sleep for only for eight hours some times less than that too.

It all depends on you how much you should sleep. If you had a hardwork the previous day or if you lack sleep there is no problem sleeping more than 9hrs. You feel dizzy because of many reasons. The main reason is that our sleep has different stages, it enters a stage every 3hrs. You will be in deep sleep for 3hrs after which if you get up, you won't feel much dizzy. Since human body requires a sleep of 6hrs a day, you will feel fresh if you wake up at around 6hrs of sleep. After 6th hour, your body again enters another 3hr phase so if you wake up in-between, you will feel dizzy or tired. The solution is don't get up immediately. Just stay awake for 10-15 mins & then get u o that you can wake up fresh & without much tiredness. Happy Lotting

yes all of us need sleep but in my case i only have a maximum of 5 hours of sleep. as of now im online daily and have to attend to some stuffs for some time.

Emm, For me,it's impossible to sleep more than 7 hours a day, except weekends.I'd like to have more than 8 hours sleep and it's good for teenager.I've learn that some students in U.S sleep less than 4 hours, I think it's so crazy .
