Does hair grow more at night than during the day?

Question

The other day I wasn't feeling well, so I slept for practically 14 hours straight - way longer than normal. And I swear, when I woke up I looked like I hadn't shaved in 5 days, I practically had a full beard.

It was weird. It made me wonder if our hair grows a lot faster when we are sleeping than when we are awake. I slept about 3x longer than I normally do. I know sleep is important, but I wonder if our bodies recover and re-grow cells that much during sleep.

Answer 1

i say yes - as the body recuperates, and young people do most of their growing while asleep.

Interesting question - thanks for that.

Answer 2

Everything is done during sleep, when it comes to the body and its regeneration and growth processes. Its a proven fact that we will not only grow in our sleep(animals,too) but we also retain everything that we learned that day and will not be able to remember any new information until sleep has occurred. This includes all growth-hair, nails, braincells, and body parts!! So, here's to a hairy night's sleep!

Answer 3

I think hair and beards don't grow the same length... But I am sure that beards grow faster then hair... really

Answer 4

seems that way for me, too. it's like i shave, and it doesn't grow back until i go to sleep and then wake up and its all back again! but that night, i'll still be smooth and well shaved! weird..=] must be..

Answer 5

if you slept 3x longer that means you sleep for 4.6 hours per 24 hours....DUDE that's not healthy

Answer 6

Apperently, yes

Answer 7

Answer 8
