Our world is sleep-deprived. In the last century, people slept an average of nine hours per night. Today, more than half the world’s population gets by on less than seven hours of sleep per night. But in an age of non-stop stimuli, what do you expect?

We would actually be way more healthy because we wouldn’t have to worry about sleep deprivation. How about that?

Hi there. This is a great video. I Think it would be exceedingly wonderful if humans didn’t have to sleep. I pray that God‘s gonna redesign his creation like that.

Question is 'what if you didn't need sleep'. So from this I assume that organs would be capable to function without rest.

The people who are around me are unemployed. I work 2 jobs. 7 days a week. They always want me to come hang out after work and none of them understand that I can’t live on 3-5 hours of sleep.

I hate needing to sleep, it's a weakness of being human. Hopefully technology will eliminate that weakness.

I like to sleep though, it's relaxing, the only real thing that can put my mind and body truly to rest

I have a 6 month old. I get MAYBE 4 or 5 hours of seep per night. Before the baby came we slept between 9 and 13 hours a day. So, If you like sleep, don't have kids.

And then someone would close their eyes and actually fall asleep and wake up feeling better than normal, they would start to sleep more often for the feeling, eventually telling others and then everybody would start doing it again. Soon, they’ll need sleep after years.

Fact: In Vietnam , there is a man who has never slept for over 45 years . His name is Thái Ngọc( u can search in Wikipedia) . According to VIetnamnets, he started not sleeping in 1973 after having a " fire" night with his wife, maybe that causes a kind of hormone that kept him unable to sleep and awake . But some say that his illness was not caused by any clear reasons . Despite not sleeping for that a long time , he is still healthy and doing works as normal people . Until now, scientists have no idea about his illness

Will we feel tired if we didn't need to sleep?
@timmym4381

If not needing sleep then means it's optional so maybe not sleep every night but a couple times a week.

I don know about most of you but I hate sleeping if that makes sense… I feel like we eventually, waste more time already and sleeping makes it worse… Honestly, if I could choose, I'll work more and spend more time with family and friends and make new memories. But with that said, I also know how important it is to sleep… to let body recover and not only from stress but to reflect on your life from time to time… So moral of the story is just sleep… Because you won't make any sense. (Writing this after being awake for 33 hours straight)
Also, my comment Is stupid… And exactly that's my point.
