Life has 1/3 hours of sleep. We know that sleeping is for better work and study, but it seems that only people in China are most persistent about taking a nap.
Friends who work in foreign companies may feel more. Many foreign colleagues have no habit of taking a nap at all, but we are always used to taking a nap at noon, otherwise we will be listless in the afternoon.
About siesta, why is there such a difference between China and the West?
In fact, there are several reasons:
The first is the influence of diet, which affects many people's health and living habits. China people pay attention to the concept of eating well early and eating well at noon, and most of them choose high-carbon and high-water foods. As a friend said, Europeans and Americans also eat sandwich hamburgers and carbohydrates, but the proportion of carbohydrates per meal does not exceed one third.
This "full" lunch habit will raise blood sugar. At this time, the body will secrete a lot of insulin, and tryptophan will enter the brain and become serotonin, which will make you sleepy. The higher the glycemic index of food, the faster the secretion of this serotonin and the easier it is to fall asleep.
The second is coffee. Many Europeans and Americans have the habit of drinking coffee. Coffee has a refreshing effect. In the west, coffee has become a necessity of their life. In Finland, the average person consumes coffee 12 kg per year, which means that everyone drinks 2.4 cups per day. The habit of drinking coffee in China is not as diligent as that of foreigners.
In addition to the above two reasons, it is actually related to various social factors and regional ideological differences. Westerners believe that it is only possible to sleep in a private environment. According to the Financial Times, most Americans still can't accept sleeping in the workplace, because they think it will give others a bad impression and it is difficult for them to fall asleep.
Taking a nap is actually very good. Why not try it?
However, the regimen left by the ancients in China is also reasonable, and taking a nap is really beneficial.
First of all, taking a nap can improve the thinking ability of the brain. American researchers have found that taking a nap can improve people's management ability and alertness. Research by Madame Dü sseldorf University in Germany shows that taking a nap can eliminate fatigue and enhance memory.
In addition, taking a nap can lower blood pressure. A recent study by researchers of Allegheny students in the United States shows that work stress will lead to an increase in our blood pressure, and a nap can better control our blood pressure.
Taking a nap has many benefits, such as preventing depression and protecting the heart. The correct method of taking a nap can make your body healthier, so pay more attention to the details.
These nap suggestions can make you healthier.
First of all, it is best not to take a nap for more than an hour. Our sleep can be divided into deep sleep and shallow sleep. After 80- 100 minutes of sleep, we will go from light sleep to deep sleep. If we suddenly wake up from a deep sleep, the process of deep depression in the cerebral cortex cannot be linked immediately. If the closed capillary network cannot be opened immediately, the blood supply to the brain will be insufficient. That is to say, many people say that the more they take a nap, the more they sleep.
Secondly, don't take a nap when you are full. Generally we are used to eating a little at noon. If we lie down and sleep at this time, it will definitely affect our digestion. If we eat too much, we may not be able to fall asleep immediately. Or walk around first and then lie down.
There are indeed many details to pay attention to about taking a nap. For example, it is best not to lie prone on the table during a nap, which is easy for the brain to lack oxygen. If the nap time is short, it is really recommended not to eat too much at noon.
