We already know that your body temperature works and
ticks like an internal clock controlling our sleeping cycles. Body temperature
also controls the metabolism, circulation and other involuntary activities our
body undertakes.
Variation in body temperature also indicates and
induces the feeling of being awake or being tired.
Reduction in body temperature induces the feeling of
lethargy, tiredness and drowsiness. Conversely, a rise in body temperature
induces the feeling of alertness, feeling of being energetic resulting in
better concentration levels.
The rise and fall of body temperature during the day
should not be misinterpreted as the need to rest or sleep. This happens many a
times during the day depending upon the body’s activity level at a given time.
When a human body is pushed for heavy physical
activity, the body temperature automatically rises and drops slowly once the
activity is stopped. This reduction of body temperature induces a feeling of
tiredness or drowsiness.
When your body does intensive physical work during
the day, you feel tired when you come back home and just want to sleep. This
does not happen due to desire of sleep, but due to drop in body temperature,
and the reaction of your body due to the drop in temperature.
If you let this phase pass and wait till your body
temperature returns to normal, you will start feeling awake and alert again.
In order to recharge your physical energies, I would
suggest, as a part of my Powerful Sleep Plan, to take a nap of 10 – 45 minutes
during the day. This nap should be taken when you feel sleepy, that is when
your body temperature has dropped as it will help in falling asleep. The nap
should not be more than 45 minutes and should not enter deep sleep. Deep sleep
will only induce further fall in body temperature.
When you wake from your Power Nap, you may feel
drowsy and lethargic due to high melatonin levels. It is important to get your
body back to normal temperature with the help of light physical movement and
exposure to light.
It
is understandable if you feel tired even when you lead a sedentary lifestyle.
This does not mean you need more sleep, but means that you need more movement
and less sleep. This happens due to frequent dropping of body temperature.
