Sleep Mathematics.

[Rruchi man]

Here is an interesting thought that Keeps me up sometimes at night, permit me to share. Please try to read to the end and drop your thoughts/comments too as well.

Say for instance, you are 30 years of age. When converted to hours, 30 years will give you 262,974.6 Hours exactly ( that is, you have spent 262,974.6 Hours on this earth). If you stick to the ideal sleeping time ( 7-9 hours of night sleep), multiply that by the number of days in 30 years which is 10,950 days, it will give you the approximate total number of hours you have been asleep for the 30 years you have been alive.

Approx time of daily night sleep x Number of days in 30 calendar years = Approx total time Asleep in 30 calendar year.
(9 hours sleep x10,950 days) = 98,550 hours sleep.

If you subtract the approximate total number of hours you have been asleep from the total hours you have been alive ( that is in 30 years), you will get the approximate total of the time you have been Awake.

Total time (hrs) in 30yrs - Approx total time (hrs) asleep = Approx total time (hrs) awake in 30 years.
(262,974.6 - 98,550) = 164,424.6 hours awake

If you convert this figure in Hours  back to years,
164,424.6 hrs ≈ 18 years 7 months 7 days.

Wow. It means you have only been active for 18 plus years of your life.

(Now imagine you sleep a lot, exceeding the 9hrs mark at night and usually the type to take long naps during the day?)

Do the Maths, Use your age and the approximate to get your own values, lol. Your will be shocked and thrown into thoughts.

[franky1]

or less complicated maths. so you get relax and get to sleep without a headache
(7-9hours=average
there are 3x8hours in a day

people sleep 8 hours a day which is ~1/3rd of a day
divide your age by 3 and thats how much time you spend sleeping

no need to stress yourself at night counting the hours.
just do 24/3 to workout the hours of sleep per day
365/3 to work out  the days asleep per year
age/3 to work out the years asleep per age

i hope you can sleep better now that you dont have to do such lengthy math

Every human in this world spend their 30% of their total life time just for sleeping and its nothing to be wondered about because if you failed to take that needed break everyday you will get depressed and even you life time may get reduced a lot.

It's not how long you are awake, but what you do with the time you are awake. Let's put aside that researchers like Mathew Walker suggest that a minimum of 7 hours of sleep is needed, the thing is that more waking hours do not equate to more positive output or output in general. So when calculating the time spent sleeping through your lifetime, you need to compare your waking hours to something it can be measured to, something that has value. So maybe try to broaden your equation to add a median of quality waking hours so that we have an idea of what to measure the sleep against.

In concordance with you, i'd like to add that being awake and unproductive is equivalent to sleeping all day.  So instead of staying all day awake being unproductive, it is best you increase your sleep time, lol.

After reading your comment, a new light of thinking is that - it is possible for one to be more productive in sleep as well.

Dreams can be productive too.

You can dream about doing some profitable business which may give a new idea to start a business and can keep making money from it.

some people can have lucid dreaming and somewhat control what they will dream and thus may come to some conclusion/result/answer that they were thinking about which can affect their day.

however sleeps role is mainly to rest so that you can have good energy during the waking hours.
EG not enough sleep say only 5 hours instead of 8 will make you feel sluggish and work at half the speed. making an 8 hour task take 16 hours.

so having the extra 3 hours to complete a good night sleep will save a 16 hour sluggish job. by being only 8 hour job

Lucid dreaming, its an interesting thing and actually 30 to 40% people are actually lucid dreamers and the others are just pretends to be one of them. Dreaming makes someone more active as you said which I read after this thread was created.

*So google even tracks my posts on bitcointalk and giving recommended contents related to it?

It's very lengthy mathematics. But when you were calculating this how much time you waste?
Now Calculate Milliseconds that you have asleep since your age.

Like the other posters wrote. Quality over quantity.

Spain is trying out a 4 day workweek don't you know? The productivity increase will far exceed the 8 hours of work lost.

Same with sleep. If you get that sleep, the remaining hours will be even more productive than if you lost that sleep and had all these extra hours. Sleep quality is a very important health metric.

If you stopped sleeping your memory and mood regulation would turn to absolute garbage.

There's a lot of scientific research and almost endless theories on the role and importance of sleep in humans and other living creatures.

Not quoting any specific research but anecdotally it sounds like a couple of the key points of why sleep is useful (beyond "curing tiredness"):
 - Repair and rebuilding the body on a cellular level
 - Neurological (brain) function, including building and "storing" long term memory

It could be interesting (thought experiment) ponder if reducing sleep overall might lower life expectancy (ignoring accidental death)

Maybe there is an upper limit to "active awake time" for any particular person.
e.g. someone who's life expectancy is 80 years, and assuming 7 hours sleep daily (56.67 years awake) if they self limited to 4 hours sleep daily would they still only achieve the same number of years awake? Therefore reducing their life expectancy to 68 years instead of 80?

Hard to say, but I think we should sleep on it.

Here is an interesting thought that Keeps me up sometimes at night

Are you saying that if you sleep less, you will live longer? I doubt it. If you sleep less than your body needs, then on the contrary, you will live less. A tired and decrepit organism will grow old and wither faster.

And if you are so worried about this issue, choose the right regime for yourself for activity and for relaxation.

[Gozie51]

You have taken a lot of time to do this calculation and arrive at active time as 18 years by your own deductions but I think that within that active times, you didn't put into consideration certain factors that can also act to reduce those active years. Example things like like falling ill. Sickness is not calculated in that make up of the mathematics. Many times we fall sick within the years and they make us inactive those times

Or don't we fall sick ?

Or don't sickness affect our active lives?

We fall sick surely and it affects our activities and that also means sickness reduces our active lives.

[semobo]

I have been working for more than 24 hours now without even a little nap and you know how much I am exhausting now just because I didn't get my sleep so it is good because it gives enough time to regenerate the energy back for the next day to start as fresh and energetic so we can be productive and creative just because of enough sleep.

[20kevin20]

It reduces our activity, but it doesn't stop us from being active. Or, are you a full-time potato whenever you get ill?

Anyway, how many times does one really get ill per year anyway? For me, it was twice at most an year out of which only 1 or 2 days were lazy-days, but definitely not full-time-potato days. In 30 years, this might account for 60 days at most of laziness, which probably is completely different to what OP seems to be calculating. When you sleep, you're not really aware of the surroundings..

[hornetsnest]

If I calculated how many hours I have been awake without sleep there would be no point in posting it here. No one would believe it anyway?

...
Wow. It means you have only been active for 18 plus years of your life.

And 10 of those watching Netflix likely.

this can be calculated. but its a low number and not affect the overall by much

however whats more life impacting lower inactivity is this:
topics known quantity so far: in 24 hours 8 hours (1/3) is sleep
but..
another 2 hours(1 either side)(1/8th) is the 50% inactive space relaxing for bed. waking up
so call that 2 hours of 50%= 1 hour of 100%  so thats 15 hours of 100% active instead of 16

sitting down for lunch/dinner might be another hour 'wasted' so now 14 hours of "100% pure active" time

..
so topic may have started as 16 hours(2/3rd's of life) active its now more appropriate to being more like 14 hours(7/12ths of life)
...
even those that say they only need 6 hours sleep. will find that their spare 18 hours are not all at peak 100%
infact those 18 hours might be 77% active. meaning 23% less energy/productive.. which would be the same as 14 hours of productive energy
not saying its 18hours of potato couch lazy. but just slower working speed. frustration at not thinking about solutions as fast, wasting 23% of time
EG what might take a well rested person 46minutes, takes you 60 minutes thus 23% less productive

yes if you truly slept for only 6 hours and you were oncall where you were at the workplace working for the entire 18 hours. your productivity might be at 77% compared to well rested coleague

It is fact that everyone needs 5 to 7 Hours daily for rest. It is a system of man that he cannot work continuously without rest. After rest, He refreshes again and again ready to work. There is a new day, new life with new feelings, determination. Rest does need counting.
Rest finishes all fatigue and tiredness and it is a part of human life. Any person can't exist without rest.
