does 4 hours sleep a day can keeps your mind active?

[3acaga]

If you sleep 4-5 hours a day - this can lead to a violation of the mental and nervous system of your body.
There are several modes of polyphase sleep:
Dymaxion - 4 times for 30 minutes every 6 hours = 2 hours.
Uberman - 6 times for 20 minutes every 4 hours = 2 hours.
Everyman - 1 time at night (1,5-3 hours) and 3 times a day for 20 minutes = 2,5-4 hours.
Biphasic - once a night (5 hours) and 1 times a day (1.5 hours) = 6.5 hours.
P.S. Sleep is your health - do not save on your health ...

In my opinion,  it's enough if you do it regular.

[pandacrypt]

Depends....
I used to have a habit to sleep around 4 hours per day, but I was not that active during my day, so it was enough.
When your activity level is rising, for example, you train at the gym or work more with numbers it effect AND SLOW YOU, but nothing to do with becoming stupid))

The average healthy sleep is 6 or 9 hours. But the individual can be statistical outliers. Human biology is diverse as hell.

4 hours sleep a day is not enough at all! It depends on your activity and environment. If you are living in an environment where you weather is always soothing i.e cold then sleeping for less than 7 hours is okay. But if you are from a place where the weather condition is drastic i.e hot and bumpy then it's always better to have 7 hours of sleep as because we lose much of energy each day!
It's said that plenty of sleep is required for good productivity all throughout the day! If you don't get enough sleep then you will feel tired and  can't concentrate on your works. Less sleep results to crankiness and temperament , so get as much of sleep as you can and you feel is enough for you.!

I think you have to balance your work and rest my friend. Working for more than 12 hours and sleeping for just 4-5 hours is not good at all.

Ok yes you will surely have lots of money but are you even having a quality time with your family? Worst is you might just spend your money to medical bill if something serious happened to because of not sleeping enough.

Its our responsibility to work hard for our family but our body desserves some care.

[Rimcoin]

it depends of persons but it is not enough to sleep 4 hours a days you need to recover energy after and you are not effective

[Gaselemeg]

I guess not. Even if you feel comfortable changing your regime and resting for 4 hours over time this will change. Because of the accumulated fatigue, you will begin to experience chronic weakness and lose motivation to work.

[GG_nick]

Yes if you do it once a while but if you this regularly, it may cause a lot of health issues eventually. The body is not designed to work at it's optimal performance with just 4 hours of sleep every day. The body requires a different number of hours of sleep depending on your age and lifestyle. For babies, of course, it is more while adults require less.

[Nazarov]

Yes, lack of sleep affects including the brain.It is certainly desirable to find time for sleep, and not to drink coffee instead

[Bobby_C_Lebaron]

I think the best sleep time is different for some people, some only sleep 4 to 5 hours a day, but usually at the end of the week spend all the time to sleep. if not then the performance and endurance will be reduced. according to menshealth(.)com good sleep time for adults aged 25 to 64 years is 7 to 9 hours a day.

[IndigoRed]

Scientifically proven that sleeping less than 5 hours a day will affect you in a really bad way. Most likely in like 3 days with 4 hours sleep you will have some galucinations. 7-8 hours of sleep is enough for a normal person. By the way, sleeping more then 10 is damaging your body too, which is kinda funny. 

Correct. We need at least 7 hours to properly rest our bodies and maintain good health. Tough to do though. With work and everything else, there's just no time. It can really take a toll on the body. Couple that with external factors such as air pollution and sometimes, bad eating habits. It's tough to stay healthy and be on top of work at the same time.

[CharlesCorley]

5 hours can be good but 4 hours regularly can be harmful.

[baeva2]

I think that for sleep 4 hours very little. The best option is to feel fine - 8 hours.

[btcdarkfanboi]

I think so if you do it every single day. But  1-2 days occasionally will be fine for me tho

[rohn]

I think 6-8 hours of sleep is enough. Study shows that depriving yourself to sleep can cause low-blood and reduce the capability of our brain to function. Our body system will be at stake if you don't meet the required time of sleep. Excessive amount of sleep can also harm our body.

[CircularLoGic]

Can't even imagine how people can sleep 5-6 hours a day and stay productive, I need to sleep at least 9 hours to feel good.

[Ceasar19]

Generally no but ther is a category of people can keep their mind active with just 4 hours

[Ciscopro2000]

I think you need at least 6 hours sleep a day.  Your mind needs adequate rest to recuperate from the daily life.  While some can function perfectly well with 4 hours, most people need at least 6 hours I believe.
