You are probably wondering about how much you need to sleep in the day
to feel good. I am no exception. Especially important this issue has
become for me lately. Parents say they need to sleep 8 hours, in books
written by seven, and recently saw on TV that Chinese scientists after
a series of experiments and tests have found that sleeping only need
5.5-6 hours a day. But this topic is not so simple. Everything else
depends on the activity during the day. So I decided to climb up on
the internet to find a few more opinions on the matter and to conduct
its own investigation of this matter.
As a rule, the border "vysypaemosti" we have moved one hour ahead than
we are usually asleep, as shown by an experience: they took 100 people
and allowed them to sleep so that they get enough sleep, before
everyone knew their average daily sleep time. This experiment was
carried out more than one day, a week, so give the person "to recover
from the harsh everyday life" and thus considered to be effective
testimony removed after 5 days of the regime. Experimental data showed
that all the subjects slept for 50-70 minutes longer than usual
sleeping. The total duration of sleep on average out of 8 hours. At
the same person continually takes readings during sleep. Examining
these changes, researchers concluded that a person enough to sleep
with an average daily load of 7:00, with polupovyshennoy - 8, and at
high load - all 10.
From another source I also deducted these figures, however, so one
more was added to the phrase: if you had slept less than the average
rate, then one day a must to finish this rule adding 30 minutes to 1.5
hours (depending on how much time passed from the waking up to the
decision "dovyspatsya").
Nagoya Institute researchers also found that most lives who slept 7
hours. In this case they used the analysis of habits 100,000 people in
10 years. What has been found that the highest life expectancy
observed in those who slept 7 hours (for what it boldly pointed out
that in the night!), The middle - those who sleep 8 hours or more, and
the highest risk of death for those who sleep less than 4.5 hours per
day. The most unexpected observation in this study is that the health
of those who sleep more than 7.5 hours there is worse than those who
slept 6.5 hours.
Another interesting fact was noted that sleep better at night than
during the day. And also while you sleep - this time from sleep to
waking, and not a time when you go to bed until the time when you get
out of bed.
Personally, I sleep in the day 5.5 - 7 hours. These studies led me to
think about it, but I think it is unlikely that anything in my life
will change dramatically, however, will not be guessing ...
