I always sleep from around 4am until 12pm (a total of 8 hours of sleep). It is kind of a Delayed Sleep Phase Disorder (DSPD)

I am from an Asian country and there people believe that you should sleep from 12am (at the latest) as this is the time where your "body will detox or repair your cells the most"

So sometimes I am worried about my health. I am asking this question whether I have sufficient hours of sleep ("8 hours"). Assuming that I sleep at 4am everyday, will my body "actually detox and repair itself"? Or is my health deteriorating every moment I sleep late?

You are not sleeping 'late' - many consider 8 hours to be appropriate for the majority of the human race. It would be late if you we sleeping from midnight to midday...You are only time-shifted. So as regards your question on detoxing - it is irrelevant.

If you want to sleep from midnight to 8am, this becomes a relatively simple problem of managing your body clock by four hours - as many jet-lagged international travellers have to do on a regular basis.

First and foremost, you need to get used to going to bed before midnight, whether or not you feel tired. This is all about changing your routine. If you do not even go to bed until 4am you certainly won't go to sleep before then!

Then have your alarm set for 8am - this will be a shock to the system for the first few days as you will only have had a few hours sleep, but this will help persuade you to go to bed earlier.

If you are in a country where the sun is bright in the morning, have your curtains open - we are hard-wired to become alert with the rising sun, in general, so this helps you wake naturally.

Avoid caffeine. Seriously. Until you are settled in the correct time slot, caffeine confuses your responses to tiredness.

Exercise well. This just helps your body do most things well - digestion, metabolism, sleep etc.

Eat healthy foods. Junk food doesn't always play well with your body, and heavy meals late at night are also not conducive to a good sleep.

actually you are wrong regarding time shift, our body is an automatic machine, which works accordingly nature, and so it does functions differently as per requirements in day and night time to regulate metabolism of body and meanwhile if you are shifting your time slot, then definitely you will suffer. i already faced many problems due to this as it causes – Sunishtha Singh Aug 7 '13 at 21:10
Actually Sunistha, you are wrong here. This works perfectly well for numerous people, myself included. – Rory Alsop Aug 8 '13 at 13:42
i am not are feeling its right, but in actual its not. i had been under spiritual teachings, mind-body-soul practices. it really disturbs all your metabolism. – Sunishtha Singh Aug 8 '13 at 15:50

you are rightly very rightly worried according to me. night is meant for sleeping and day is meant for handwork. going against the nature will definitely have some consequences in the long run (you definitely will not be at your optimal concentration and productivity sleeping at your time). the best sleeping time is about 10 pm to 5 am or 6 am in the morning and the best natural productive time is from then onwards. sleeping till noon you are missing out about 6 hours of highly productive hours. if you are in technical job this is not a good miss according to me. you will come to know of the benefits of sleeping early when your body will become really use to this time.

sleeping at the appropriate time but being a couch potato will also not work. go for a run for at least 30 minutes per day in the morning. eat food that produce energy. eat two three bananas in the morning and at night after your days work. avoid computer or TV at least an hour before sleeping. interact with love ones for at least some time every week. this is all part of a very healthy life style. best of luck for that!!.

Please edit this answer for clarity. I believe you are misusing "am" meaning "pm", but I'm not enough certain of your intent to make that edit myself. – Dennis S. May 3 '13 at 13:17
I'm sure he meant 12pm. I've edited it to "noon" to be clearer. – Jeanne Boyarsky May 3 '13 at 14:52
  • Will my body "actually detox and repair itself"? - Yes

  • Is my health deteriorating every moment I sleep late? - No

(As long as you get good deep sleep between 4 am and 12 noon)

Sleep does help our body to maintain itself. Ideal sleep varies for each of us. 6-8 hours is considered to be good enough.

We learn from the nature. As the nature gets into sleep, so should we. I dont know the scientific reason for this. But I feel there is some reason nature follows this pattern. I just don't know the reason now.

In India, instead of sleeping at 12 am, it is advised to wake up 2 hours before sun-rise and sleep for at-least 6-8 hours. That would put the sleeping time at 10-12 pm (assuming 6 am as the sun-rise).

Can you write more on that India's technique ? Wake up 2 horus before sun-rise for how long and what should i do during that time??? It doesn't make sense. If I sleep from 12am to 4am, wake up and go to sleep again for 6-8 hours it's 10-12 hours of sleep! – Skuta Aug 14 '13 at 9:29
