Night, as one can define, is the period
between sunset and sunrise. Nevertheless, it has got its own
interesting features.
Except for the “Nyctophobics”, who are afraid
of the night and darkness, night-time is usually synonymous
with slowness, dullness, low activity levels etc.
Have you ever thought why in movies night is always the chosen
background for execution of a cold murder? Why tree-top spirits
and ghastly-ghosts feel free to display themselves scarily
only in utter darkness? Why should any out-of-the-normal activity
take place only during the night in movies? That’s because
night is always associated with crime, eeriness, and fear,
and we have quite grown-up with this mindset. But, in reality
“night” is a very positive happening. Read on
how!
Day-Night rhythm
Except for those living in the
poles, where they have continuous days and continuous nights
for long periods, we on the other parts of the Earth are blessed
with a rhythmic day-night cycle where once in 24 hours we
could wake up fresh after a good night’s sleep. Because
of the rhythmic day and night cycle, our body is also tuned
into a “bio-rhythm” also called as “Circadian”
rhythm controlled by our brain, where each person has his/her
own time and order of doing things the same way each day.
We can identify our most efficient or most depressed time
of the day by this regularity. Our body assumes brightness
or sunlight to being active. Sleep is the most beautiful thing
that can happen to our body during night in this day-night
cycle.
What happens to our body
during a night's sleep?
It is a fact that one can voluntarily
deprive oneself of food and water until death, but not sleep.
So, it is important to fall asleep naturally, in a regular
manner. We may think that the brain and the body are quite
resting inactively during our sleep, but actually the body
undergoes repair and detoxifications and a whole lot of functions
are taking place to keep us mentally, emotionally and physically
healthy.
When we say sleep, here it means
the more common night-sleep. So, what happens when we sleep?
As we fall asleep, the body temperature, heart rate, and breathing
come down. Many hormones get released, all muscles relax.
As the body temperature falls down, “Melatonin”
the sleep hormone is produced to help accelerate the sleep
process.
As the morning approaches, heart
rate increases, blood pressure goes up as well as the body
temperature, in anticipation of brisk activities ahead.
This type of a bio-rhythm existence
helps in medical diagnosis as well, since issues like arthritis,
allergic rhinitis, chest pain, asthma, heart attacks; strokes
are more common during the early day. Epilepsy occurs in a
more individualized pattern. Do you know? 1. We are not supposed to take
food late in the night or sleep just after food because when
our body is immobile and inactive, the digestion processes
is sluggish and so stomach enzymes and acids do not convert
food into energy during the night.
2. We may feel our mouth being dry as
soon as we wake up because there is decreased saliva production
during the night.
3. The first urine is concentrated because
the kidneys have slowed down their waste removal process during
the night.
4. During deep beauty sleep, the skin's
metabolic rate speeds up and many of the body's cells show
increased production and reduced breakdown of proteins, thus
helping cell growth during the night.
5. When we sleep, all our muscles relax
including the throat muscles, and the opening narrows down
to a small hole, and if the muscles are weak and fall back
to obstruct the airflow, then snoring happens during the night.
6. Night-shift work means the need for
the body to fight against the body’s circadian rhythm,
which in turn depends on the natural day-night cycle. Day-time
sleep cannot compensate in quality or quantity of a good night’s
sleep, though the sleep-debt could be and should be made good
in order to minimize the fatigue and maximize the performance
at work-shifts during the night.
7. Jet lag or “Desynchronosis”
is nothing but disturbance in the sleep pattern due to the
alterations of the body's circadian rhythm as one passes through
different time zones in a plane. Traveling East-West affects
more than traveling North-South.
So, Good-Night Every
Body!
