At noon, we should pay attention to the work of lunch break. At ordinary times, we should also pay attention to the appropriate relaxation of their mood, so that everyone's health and work, have a good improvement. One day, office workers are facing the computer, such a day the spirit is easy to decline. After lunch, a proper rest will be good for the spirit of the afternoon. How long will sleep be good for everyone's spirit?
7 benefits of napping
1. Eliminate drowsiness
People tend to feel sleepy after lunch, because more blood into the stomach to participate in food digestion, leading to less blood circulation in the head, and insufficient blood supply to the head, resulting in fatigue and sleepiness. And a nap in the afternoon can eliminate the sense of drowsiness, invigorate the spirit, so the nap has a "charging" effect.
2. Improve memory
We are absorbing new knowledge every day, but at the same time we are losing part of the ability to absorb new knowledge. Taking a nap can slow down this decline, and a 10-30 minute nap a day can restore cognitive ability and improve people's memory.
Researchers have found that napping significantly improves energy and alertness, while a study at Dusseldorf University in Germany shows that napping not only eliminates fatigue, but also improves memory.
3. Avoid obesity
Lack of sleep at night can make weight gain, because in the process of sleep, our brain produces a special metabolic control signal, so that the body can actively play various metabolic functions, thus affecting our weight. Appropriate nap can supplement sleep and make up for the lack of sleep at night. Especially between 12 and 13 o'clock, people's physical fitness will decline, which is the most suitable time for nap.
4. Improve immunity
Sleep experts found that 1:00 p.m. is a peak of people's sleep during the day. A short sleep at this time can effectively stimulate lymphocytes in the body, enhance the activity of immune cells, and thus enhance human immunity.
5. Prevention of coronary heart disease
The new supersedes the old. 10-30 naps each day can relax the brain and body system, slow down the metabolism, reduce body temperature, reduce oxygen consumption, reduce cardiac consumption and arterial pressure, and make the secretion of cardiac hormones more balanced in vivo, and reduce the incidence rate of coronary heart disease.
The incidence rate of coronary heart disease is very high in Nordic and North American countries, and the incidence rate of coronary heart disease in Mediterranean countries is obviously low.
6. Improve mood
Through the busy morning time, taking a nap at noon can temporarily forget the worries and pressures of work and study, relax the body and mind, relax the tense nerves temporarily, and play a role in regulating mood. Afternoon with full enthusiasm and positive attitude to work, study again.
7. Napping lowers blood pressure
Researchers' latest research found that if the work pressure is high, people may as well take a nap for a while, which will help lower blood pressure.
Napping for more than 30 minutes is worse
Health experts point out that, from the point of view of the physiological clock, the spirit of about 2-3 hours after a meal is really bad, and it is related to the lunch diet. If you eat the food that is not easy to digest (such as: fried chicken, French fries, hamburger and other high sugar, high fat, low protein and rich carbohydrate food), or eat too much, it is easy to make blood sugar high, aggravate the situation of blood concentration in the digestive tract, making people feel To drowsiness.
However, some people need a nap, which may also be a warning of insufficient sleep at night. If they find that they take a long nap after taking a nap, it is likely to mean that they are not getting enough sleep and need more sleep at night rather than just taking a nap.
In recent years, a number of international medical literature have confirmed that nap can really improve the spirit, but the best time is about 10 minutes. In this study, the subjects were tested at 5, 10, 20, 30 and 1 hour naps respectively. In addition to observing the depth of sleep and understanding the mental state after waking up, the results showed that those who took a 10 minute nap after waking up could obtain the best mental state, while those who slept for more than 30 minutes had worse mental state.
Health experts explain that because people have a "sleep habit", it is not easy to wake up if they take a nap too long. In the first half hour of waking up, there will be slight headache or general weakness, which can only be restored after an hour of buffering. Therefore, the longest nap time should not be more than half an hour. Otherwise, you will enter deep sleep and wake up feeling drowsy, and even disturb the physiological clock, affecting the night sleep.
