Just so-called: do not sleep at noon, collapse in the afternoon.
Many people take a nap after lunch.
And in the past, some Western countries thought that napping was just a wasteful phenomenon, a manifestation of laziness.
However, more and more medical studies and experiments have proved that ---- proper nap can effectively alleviate excessive fatigue and prevent sudden death caused by cardiovascular disease.
Why do we take a nap?
Most naps are "compensatory", that is, used to make up for lack of sleep, even when the body is uncomfortable, naps can also "compensatory" cultivation and adjustment of the body.
In traditional medicine, 11:00-13:00 a.m. is noon, and noon is the time when the heart meridian is ordered, which is the time when yin and yang alternate. From the time of the child to the beginning of the yang qi rise, to noon is the time when the yang qi is at its strongest, so Chinese medicine is called "Heyang".
Once the yang qi reaches the peak, the prosperity will decline, and the yin qi will also begin to grow, and in this moment of "moving yang and quiet yin", it is necessary to meditate, lie quietly and sit quietly for 30 minutes at noon, which can not only generate yin qi, but also protect the heart.
Napping, have you really learned?
The Japanese writer Haruki Murakami once said: If there is no such thing as a nap in the world, my life and works may seem darker and more difficult to get close to than they are now.
In recent years, the benefits of napping have also been confirmed by many scientific studies.
According to the Washington Post, Japan is currently embarking on a "nap revolution", and many bankers and government officials are taking a nap during their lunch breaks, hoping to lift their spirits and effectively cope with the afternoon work.
At present, many experimental evidence and medicine show that scientific and effective naps are a good way to alleviate people's mental insufficiency and improve the efficiency of work or study.
But napping is also exquisite.
First, the nap position should be correct
Because office white-collar workers do not have the conditions for normal naps, so many people can only lie on the desk to sleep for a while, in fact, poor sleeping posture, not only will affect the health of the body, but also may induce some diseases.
When napping, remember not to compress the internal organs, it is best to lie down on the sofa to nap, the best sleeping position is high and low, lying on the right side, so that it is not only easy to fall asleep but also to avoid adverse hazards.
Second, naps should not be too long
As the name suggests, nap is that after lunch, because the body will be in a sleepy state, take time to sleep for ten minutes or half an hour, so that you can effectively alleviate the feeling of special sleepiness, and will not affect the afternoon work.
In general, the time of afternoon sleep should be controlled at about 15-30 minutes, try not to exceed an hour, otherwise the sleep time process will feel headaches and fatigue.
Third, drink a glass of water after your nap
Many people have a feeling of not waking up after napping, and they will also have a state of mental trance and unintentional work.
As everyone knows, if you drink a glass of water after waking up, you can wake up the sleeping cells of the body, and you can also make the whole person become very awake.
For some people engaged in high-risk occupations, it is necessary to drink a glass of water after a nap to reduce the risk factor.
Fourth, pay attention to keep warm during naps
The human body is easily out of temperature after falling asleep, so that the colder it gets the more you sleep or you are awakened by freezing.
Even when taking a nap, you should pay more attention to keeping warm, such as wearing a coat or covering a small blanket, etc., to avoid being frozen awake.
If you do not do a good job of keeping warm during nap, it may also cause cold symptoms.
So, today, did you take a nap?
