People's body temperature comes from the amount of heat energy provided by food, so low-temperature health preservation should start with three meals first, and grasp four points:
Three meals tend to be cold food, such as duck, fish and shrimp, aquatic plants such as rice, lotus root and bamboo shoots, overwintering vegetables such as Chinese cabbage and radish, mushrooms grown in the shade such as mushrooms, and fruits ripe in winter such as pears, dates, apples and wax gourd. These foods are characterized by high water content, cold nature, nourishing yin and moistening lung, regulating yin and yang, and lowering body temperature. ?
Limit your appetite and eat seven points full. The more you eat, the more calories you produce, which is easy to raise your body temperature. Foreign studies show that eating less can lower the body temperature of animals and reduce the mortality rate by more than 1/3. ?
Drink plenty of water, especially cold water. The method is: after boiling tap water, put it in a stainless steel or glass container and let it cool naturally to 20 ~ 25℃. Besides cooling, cold boiled water can also beautify the skin. The secret is that after high-temperature cooling treatment, the properties of water have changed, such as the gas is reduced by half, the cohesion is increased, the molecules are closer, the water in biological cells is closer, the affinity for human skin is enhanced, and it is easier to penetrate into the skin, making the skin look soft and fit. On the contrary, hot drinks such as boiled water and wine, as well as hot food such as hot pot and barbecue are rare. ?
People who love tea should drink hot tea, which can cool down more than herbal tea, warm tea or even cold drinks such as soda and ice cream, which is the latest conclusion of British researchers. They asked a group of volunteers to drink herbal tea, warm tea and hot tea respectively, and at the same time measured their body temperatures. The results showed that the temperature of people drinking herbal tea dropped by 0.5 ~ 0.8℃. Drinking warm tea lowers the temperature by 0.8 ~ 65438 0.5℃; The body temperature of people who drink hot tea can reach 1 ~ 2℃ and can be kept at 15 minutes or more. The explanation is that hot tea can make sweat pores on the body surface open, sweat glands relax, sweat freely, emit heat in the body, and get the overall cooling effect. ?
"low temperature sleep"
People's body temperature is not constant for a day, but is in a dynamic change. At 9 ~ 1 1 in the evening, it began to decline, and in the morning, 1 ~ 3 reached a low point, and slowly rose around 8: 00 in the morning, reaching a peak after dinner (7 ~ 9: 00 in the evening). It is not difficult to see that when you sleep at night, your body temperature and blood pressure are lower, your breathing and pulse are slower, and your basal metabolism is milder. In fact, it belongs to the category of "low temperature health preservation". In other words, a good sleep also helps to keep healthy at low temperature. Get enough sleep, 7-8 hours every night, to avoid excessive nightlife, or even crazy play all night. Don't turn on the light to sleep. Research data show that exposure to light at night will lead to an increase in body temperature. Open the window, don't hang the curtains, and keep the room temperature low. Turn on the air conditioner if necessary.
