The study examined a sleep schedule equivalent to 5.6 hours per day. That's not studying if sleep deprivation can be made up, that's simply studying sleep deprivation.

My own experience with sleep deprivation is that the sleep it takes to make it up is longer than the amount of sleep I was missing, especially if I put off the recovery.

I've got a different experience; ~14 hours is the maximum sleep needed to completely recover.

I get by on 2 hours of sleep a night all week and just have an extended 14 hour sleep on Sunday.

I've been doing this for about 3 years now so maybe I'm just used to it.

I think this is interesting, I've never heard nothing similar. Do you feel tired during the week? Can you concentrate on difficult tasks that requires attention?

[zepolen]

I feel tired as the day ends, but never that I'm too tired to think stage until just before I'm ready to sleep.

There are several study's which suggest you are shortening your lifespan.

I am awake 30 hours more a week than on the regular 8 hour sleep. By the time I'm 50, I've have been conscious 5 years longer than most people.

I don't think you'd meet any older person who won't trade 20 of their older years to be 5 years young again.

So while my absolute life span may become lower, I'm living more of it now rather than later; Besides, who knows when you are going to die anyway, could even get hit by a bus tomorrow.

Also the abuse my body is going through, I doubt it will live to a ripe old age, I both smoke and drink and have cancer in my family history. I doubt I'll make it past 50 anyway.
