Why other primal need in our lives. One approach

Why
do we sleep?

We
rarely think about why we sleep. Yet, we can all agree that we cannot do
without it and at some point sleep makes us feel better. Conceivably, sleep is
one activity that both humans and most animals engage in. It is true that we
have different sleeping schedules yet it is also true that sleep is just as
basic as other primal need in our lives. One approach that can help in
analyzing the importance of sleep is to compare sleep to other humane
activities let say hunger. I know it’s fairly easier to comprehend the role
eating plays in relieving hunger, practically; sleeping and eating are not that
dissimilar. For instance, sleeping relieves overall exhaustion and sleepiness
just as eating relieves hunger. For a while it was conceived that sleeping is
an inactive state for both the mind and body. However, over the years research
has established that sleep is an active period with its own distinctive and complicated
physical and mental mechanics.

Scientists
have tried exploring on why we sleep from multiple approaches. In one approach
scientists studied the effect of sleep deprivation on human and animals. In
another, they analyzed sleeping patterns in an attempt to draw conclusive
remarks on the function of sleep and in another study researchers theorized
that we sleep due to the body’s energy demands. Nonetheless, regardless of
multiple researches on the aspects of sleep the answer on why we sleep still
remains elusive. For a while, it had been difficult for
scientists to pinpoint on why we sleep due in part to the fact that they
assumed that the brain was inactive during sleep. However, multiple researches continue
to be leveled on this field. Though, still unproven multiple theories on sleep
have added up to bring an understanding to why we sleep. Research on sleep
particularly, sleep deprivation suggest that sleep is essential in ensuring
that the brain functionality stay a put. Experiment on sleep deprived rats
proved that when one is sleeping unimportant connections are trashed and
important ones are reinforced. Moreover, in a study conducted in 2013,
researchers conceptualized that the glymphatic system naturally occurred during
sleep and is solely responsible for waste removal. From this study we could
gather that sleep is important since it renews brains functionality. When we
sleep, the brain rests so as to improve and recalibrate our synapses as well as
enhance our memory skills. Apparently, we can all relate to sleep essentiality
since when we are deprived of sleep we tend to feel irritable, more tired, less
effective and very clumsy.  In yet
another study, scientists identified that sleep helps us consolidate our
memories. Conceivably, we take in a lot of information when we are awake. In
essence, such information is just not directly logged into our brains. Rather, through
systematic and complex processes the information is processed, and then stored from
the short term memory to the long term one when we are asleep. In addition,
research affirms that sleep is crucial in performance of memory tasks.

Of
course some of the above explanations on unraveling the sleep mystery are quite
ambiguous. For a fact even the pioneer in sleep research, William Dement, was
unable to point out to why exactly we sleep, he states; “As far as I know, the
only reason we need to sleep that is really solid is because we get sleepy.”
Nonetheless, while the recommended sleep dosage varies from children to adults,
too much sleep like too much of every other thing in life has it effects. It is
believed that too much sleep can confuse the part of the brain that is
responsible for controlling the body’s daily activities. I guess this explains
why we feel drowsy after too much sleep.
