Minimum how many hours rest required per day?

if u are not into yoga and meditation then u need minimum of 6 hours of sleep but if u r into yoga and meditation then u will only need 4 to 5 hours of sleep per day

I usually get around 6 hrs of sleep a day. Sometimes it'll be 4, but that still is enough for me. I'm use to having low amounts of sleep.

for me 8 hours

I have to have a minimum of 6 hours of sleep or I don't feel very well the next day. Eight hours is better, but I rarely get hours of sleep.

i usually sleep for 7 or 8 hours a day

I have read that 8 hours per day of sleep is the ideal for most people. I try to get at least 7 hours per night myself. I think I'd fall over if I only slept 5 hours per day. This is a good website that discusses sleep, how much is normal etc. Sleep 101 www.webmd.com/content/article/105/107660.htm
