As the saying goes, "Don't sleep at noon, collapse in the afternoon". Some people, no matter how busy, only sleep for a little while at noon; but some people rarely take a nap, so will there be a difference in long-term health?
Previously, in an interview program of CCTV News, Academician Zhong Nanshan once said that for him to sleep well at noon is equivalent to fueling his body.
Academician Zhong Nanshan still insists on going to bed at 11:30 p.m. and getting up at 7:00 a.m. At noon, I will rest for half an hour, make up for 8 hours a day, and the elderly who are now in their 80s are still energetic and energetic, which makes people envious.
Naps are also good for the body -
After a morning of work and study, whether it is physical or mental, in a state of high concentration, fatigue will inevitably occur. Proper napping can supplement brain power, can make the afternoon state more energetic, improve work efficiency, the benefits of napping are the following:
Insisting on proper daily sleep can reduce the incidence of coronary heart disease and cerebral infarction;
Taking a nap every day for a period of time helps our blood vessels to be relieved from stress and work, which is beneficial for blood pressure health.
, so that the body's lymphocytes are enhanced, every day at noon proper nap, will alleviate bad emotions, the brain get rest, improve the afternoon work efficiency.
In addition, for patients with brain naps can make the brain rest, the mind is clearer, improve work efficiency; physical workers nap can make the body rest, work more energetic.
Students' naps can be conducive to afternoon learning, more concentrated attention in class, and learning efficiency is improved; naps in the elderly can slow down the development of diseases and make the body maintained. However, we must pay attention to the fact that naps should develop good habits, do not go to bed immediately after eating, and do not develop bad sleep habits.
But napping has 2 disadvantages, and people who neglect it may sleep more and more short-lived
1. The more you sleep, the more tired you get
Some people feel very uncomfortable after a nap, they feel tired, and this is the first big disadvantage of napping: the more you sleep, the more tired you get!
As the temperature continues to grow, some people think about turning on the air conditioner, and it is easy to sleep for a long time in the air-conditioned room for a long time. Especially on weekends or rest days, many people close their eyes and open their eyes, and the afternoon passes.
When I wake up, I feel tired and sleepy, and it is better not to sleep, in fact, this is because I have slept too much.
A full sleep cycle is about 90 minutes. Usually people go into deep sleep half an hour after falling asleep, when the blood flowing through the brain tissue is relatively reduced and the muscles are in a relaxed state.
Forced to wake up the body, the body may still be in a state of "do not want to wake up", the body is prone to fatigue and fatigue, accompanied by headaches, general weakness and other symptoms.
It is recommended that you do not spend too long, sleep for 20 to 30 minutes is the best, the longest is not more than 40 minutes.
2. The more you sleep, the worse your body gets
They all want to lie in bed and get a good night's sleep, but reality doesn't allow it.
For us who work part-time, we really don't have this condition, that is, to find a place to lie down for a while.
But sleeping like this for a long time, it is easy to sleep out of a disease!
Long-term lying on the stomach to the body spine damage is very large, lying on the spine is into a "C" shape, lumbar spine, thoracic spine, cervical spine is not normal physiological curvature, resulting in the neck is very uncomfortable, long-term will lead to cervical spondylosis, intervertebral disc herniation of these diseases.
When sleeping on the stomach, it will increase the compression of the eyeballs, increase the intraocular pressure, and insufficient blood supply to the head, so after waking up, there will be symptoms such as dizziness and cerebral weakness.
It is recommended that office workers can buy folding beds or U-shaped pillows, etc., and can put the U-shaped pillow on the neck during lunch breaks and sleep on the back of the chair, which is conducive to the health of the body and reduces the appearance of soreness.
Don't blow the air conditioning fan against each other
Now that the temperature is rising, many people have short sleeves worn on their bodies, and for some people who are afraid of heat, they like to air condition the fan during naps. Sleeping in this way is not only easy to catch a cold, but also prone to problems in the shoulders and neck, and even some people have facial paralysis.
Recommendation: Do not adjust the air conditioning temperature too low during napping, it is appropriate to 26 ° C; do not let the air outlet face yourself, and cover a thin quilt during napping.
Neither type of person should take a nap
Naps have many benefits for the body, but not all of them are suitable for napping.
Naps are not recommended for those who are prone to insomnia and have difficulty falling asleep if a nap can exacerbate insomnia at night.
For patients with low blood pressure, it is not recommended to take a nap in a place with too high a temperature, which can easily aggravate hypotension.
