The power of “power nap”
There is a good
reason why the afternoon nap is said to be a "power nap", that is, a
refreshing sleep. In fact, if you decide to "take a nap" in the
afternoon, it could have many health benefits.
When you are sleepy,
everything seems wrong and people and things get on your nerves. You can fix
all this with a nap of 15 to 30 minutes.
If you feel
your energy is running low in the middle of the day, do what people regularly
do in Mediterranean cultures - "catch a nap".
If you don't
practice that, you might want to change your mind about the benefits it brings.
Power nap boosts immunity
Insufficient
long sleep impairs your hormonal and immune function by increasing the amount
of otherwise useful inflammatory proteins of the cytokines and stress hormones
cortisol and noradrenaline.
In 2015, one study
found serious disorders in healthy volunteers who were allowed to sleep for
only two hours one night.
The next day,
part of the volunteers slept twice for half an hour and the rest did not nap.
Tests showed that, after a nap, cytokines and hormones returned to normal in
the first group. Thanks to the control of stress hormones, regular naps save
your heart and brain, two major targets of anxiety.
It sharpens the focus throughout the day
Short afternoon
sleep improves attention and efficiency, research has shown. A half-hour power
nap eliminates drowsiness and fatigue and enhances mental abilities such as
concentration, flexibility, and creativity. It is even more advisable to nap
several times for 10 to 15 minutes, in which case the positive effects occur
immediately after opening the eyes, while longer naps require awakening.
Raises physical endurance
A power nap has
a beneficial effect on the physical endurance and performance of physical
tasks.
For research purposes
of a 2007 athlete survey, volunteers were instructed to run after lunch and
again after an afternoon nap. Post-nap times were better, leading researchers
to conclude that afternoon naps boost both mental and physical abilities.
A nap allows for better night work
Whether you
work or study at night, either regularly or occasionally, a nap before night
shift will help you stay fresher and work better.
Studies
examining this phenomenon have indicated the effectiveness of naps between half
an hour and four hours before night work begins. Such preventative naps also
enhance the concentration of drivers returning home after a night shift.
Improves memory
It is well
known that regular nighttime sleep helps to remember. If you have been studying
during the day, you will better remember what you learned after an all-night
sleep. A study published in 2010 in the Neurobiology of Learning and Memory
found that afternoon power nap plays an equal role.
At noon, the
respondents were tasked with memorizing certain information. One group then
slept for an hour and a half, while the other group was not allowed to nap.
Later that afternoon, those who were napping had a better memory test.
The perfect dose for a nap? 20 minutes!
The ideal
duration of an afternoon nap is 20 minutes, according to experts in this field.
This kind of
nap is what most people need to get rid of drowsiness and get an injection of
energy. A person who sleeps for only 20 minutes does not enter the rapid eye
movement phase, a deeper phase of sleep that requires longer awakening. Thanks
to this, a 20-minute dream offers extraordinary benefits because it is possible
to get to work immediately afterward.
Nap and caffeine: a shock combination!
Snooze and
caffeine combined work better than either alone. A 1994 study found that
surgeons would stay fresh during a full day of duty if they snooze and drink
coffee.
Take care of your health, take a nap in the afternoon !
