we sleep, a long series of regenerating reactions happen in the body,
making us healthy and disease free. To get the most possible out of
sleep you should go to sleep at pretty much the same time every night
up at the same time, and sleep in a cool, dark room.

depending on their age. If you get enough sleep in the correct

you sleep, the body’s energy consumption is lessened by reduced body
temperature. When this is lower, the body does not need a lot of energy
to keep going, which is why you do not have to eat at night. This is an
evolutionary trick, found in almost all mammals; when it is dark it is
hard to find food, so lowering energy consumption by lowering body
temperature makes sense.
to this, the body’s
ability to lower
the body temperature is disturbed if you do not sleep
enough. A series
of controversial studies showed this. In this, scientists prevented
rodents from sleeping for weeks, by either giving them electrical
shocks or putting them on a platform that tilted as soon as they closed
their eyes. The animals died after a very short time, because their
body temperature rose explosively; when they were not able to sleep
their body’s thermostat completely failed.
proven to have a big, beneficial effect in this area. When we are awake
the organs are constantly working, which slowly breaks them down. The
benefit of sleep on rebuilding them is very significant; during sleep
we produce hormones that contribute to the restoration of
the brain and
vital organs. Furthermore the reduced energy consumption allows the
body plenty of down time to do construction in the body.
Strong Immune System
of the effects of lack of sleep on the immune system is reduced
production of certain chemicals. Interleukin-6
is one of these; an
infection fighter that has also be proven to play an important part in
the killing of cancer cells.
on rats have shown that they will
develop various infections and die very quickly when robbed of sleep.
The reason may be that the immune system’s white blood cells and
antibodies stop reacting as they are supposed to.
mentioned before, another benefit of sleep is that it
is vital for rebuilding
the brain. This is especially true of the dream
phase of sleeping; it is mainly here that we store events in out
memory. During the so-called REM sleep we play a sort of film that
works by directing the various information to the proper parts of the
sufficient sleep the information is not stored properly,
making it much harder to recall events later. If you sleep too little

issues solving tasks that you are used to, but performing new ones
might be much more difficult.

able to concentrate when being tired. However, new studies show that we
also store information in the brain when we are awake, where scientist
previously thought this only happened during sleep.
studies show that another benefit of sleep is that it keeps

means that not getting enough sleep can
cause serious illnesses in the long-term. In the studies, the

The results showed that almost a third of the people
who slept less than five hours every night had pathogenic
atherosclerosis in their veins. In participants that slept an extra
hour every night the number fell to every tenth, and the risks were by
far the lowest in the people who slept more than 7 hours.
reasons for these results
are not yet determined, but one possibility could be higher blood
pressure in people who slept less. High blood pressure
makes the risk
of atherosclerosis higher.
studies have shown that bad or too little sleep can be a major
contributing factor to obesity. An American study showed
who sleep on average 7.7 hours every night were generally thinner than
those who slept less. When we sleep the body reduces the levels of the
stress hormone cortisol

almost anything, which can cause over intake of calories. Whether you
can sleep your way to weight loss is yet to be determined, but getting
enough sleep will definitely help. Sleep is proven to have other weight
related benefits; it increases the body’s sugar and fat burning
Your Spirit Up
importance of sleep on your mood is immense. If you do not get enough
sleep for more a longer period of time, it is guaranteed to be
effected. There are many reasons for this, one being that lack of sleep
causes hormonal imbalance.
French study showed that it took only six
days with only four hours of sleep every night, to completely change a
person’s hormonal profile. The hormonal profiles where similar to those
of very aged people and people with depression.
