1/3 of how long they live...we spend on average 1/3 of our whole lives in bed asleep!
so usually over 20+years of everyones lives is spent in bed...what a waste! but if you didnt sleep you wouldn't live very long, so its a necessary evil and a part of life..
Well... an average adult sleeps an average of 8 hours per night, multiply that by 365 days and you get 2920 hours a year. A child would be an aver age of 10 hours per night, and therefore, 3650 hours a year!
The average person spends approximately 33% of their life asleep. So if a person lived to be 90 years old, then they would have been asleep for 30 years. So the number of years depends on how old you are. A 9 year old would have slept for 3 years.
Sleep duration varies by age, and by individual. Older adults are likely to require more sleep than the 7 to 8 hours recommended, as do younger individuals (14 to 17 hours for infants, down to 8 to 9 hours for teenagers).
Getting the optimum sleep in an average year (365 days) would total 2555 to 2920 hours. In one study, one-third of healthy adults got less sleep, and one-fifth of healthy adults got more sleep.
Now the average human sleeps 9 hours a day so simply multiply this figure by the
number of days in a year and you will get your answer.
There are 8736 hours in a year on leap years,but there are 8760 hours in a year on normal years.
1 year = 8,765.81 hours.
If you meant human: on average, a human should sleep at least 8-10 hours, no more, no less. but on average, human normally sleeps for only 5-7 hours.
They dont sleep.
9-10 hours of sleep.
on average you sleep 9 hours a day and there is 365 days a year so 9 X 365 = 3285 hours a year and you live for approximately 60 years so on average you sleep for 197100 hours in 60 years !
25+ years. Depends how old the person lives and the average amount of sleep each night. If average age= 80, and the person sleeps on average 8 hours per night, he/she will have slept almost 26 years in their lifetime
Sleep requirements vary with age. The average best sleep for a normal adult is seven and one-half to eight hours.
The average American lives 74.1 years and sleeps 1/3 of there lifetime. 74.1 years = to 649400.629378 hours X by .3 = 194820.1888134, so the average American sleeps about 194,821 hours of there 649,401 hours of life.
they're human aren't they? so wouldn't the answer be how many hours of sleep does a human need? and the answer is about 8 hours.
Donkeys rarely sleep. If they do sleep then it is like that of a human.
they get 15 hours of sleep
I've read a survey before that men sleep with on average 7.9 woman in their lifetime and women sleep with 8.2 men on average
The average adult human sleeps for eight hours. It depends entirely on the individual. I personally only sleep for around 6 hours a night.
