Feel fully refreshed on 4 hours sleep a night

I usually sleep 4 hours a night, sometimes it’s around 5 and when i drank allot of alcohol the night before i sleep about 6-7 hours.
I began asking myself why this is when i had a tight work schedule, i’d be gone for work from 7am to 7pm and i realized how little time i would have left if i’d sleep 8 hours a night, i began asking myself if it was healthy at all, but i feel fine!
When i read scientific articles about how much sleep you need to stay healthy i’m baffled because i only need half of that.

I dunno why but I find it hard to concentrate on work, like my uni essays, during the day(when I use to get 7-9 hours sleep.) About 3 months ago I just started staying up at night and doing my work. I found that it was clearer to think about/struture/phrase/write. The mornings were a pain for about 2-3 weeks but since then I’ve been getting about 4 hours a night sometimes more sometimes less. I’ve started waking up before my alarm goes off. I don’t feel any different but i’m concerned it might be having implication on my health. Hope not, but yeah I feel the same as before. if not better because i chill out all day lol.
I must be a night owl???
Thoughts anyone?

Afterthought:don’t drink alcohol, 1 cup of tea in morning, odd can of coke.

...but eventually it takes a toll on your body. Anything less than 5 1/2 hours a night and you’re asking for problems. Our bodies need time to heal and refresh during sleep.

i sleep about four hours a night, but mornings suck!

I’ve tried things from polyphasic to herbal tea…if anything can get me fully refreshed I’ll try it!
Oh and Winston Churchill and Thomas Edison could do this.

I want to do this

I’m trying to remember when I started this process, how I lost and finally regained it. Hopefully more soon.

This is something that must be earned or genetically inherited. To earn this privilege is like working at the fitness center to sculpt a nice body. At 1st it will causes pain, which triggers evolution, and the body goes through something I call the misery period but after that the body adapts gradually and learn how to survive and learn how to speed up recovery time in 4 hour period. It will hit REM faster. Don’t eat or drink water, take a shower, must be real dark ( total blackness ) to exersise this value with lest pain. Don’t party, workout or drink alcohol or do any drugs or anything that may get you sick, if you start to get sick stop and start all over again as soon as you feel strong again. Progress will vary with different people depending their genetics but it took me like a month. Once I achieved this goal I resumed to my all my activities like working out, eating before bed, etc..

Last year, i would live off of 4 hrs of sleep EVERY night. I felt fine, got good grades and everything. for the past few months, i’ve been needing 6 or even 7 hrs and still feel completely drained. WHAT IS HAPPENING???

No matter what time I go to bed, I wake up with out an alarm clock and just about exactly 4 to 4.5 hours after falling asleep. I never trained myself to do it, I just always have since I was young. I never feel tired. I don’t drink coffee and I don’t drink much of anything with caffiene in it or any other energy substitutes. I don’t do it on purpose.
