They can always eliminate their worries, loneliness and depression and be calm, calm and calm. This can promote the normal operation of various systems in the body and is beneficial to physical and mental health. Being positive and enthusiastic about your work will make you nervous, look tired, depressed and prone to illness. A few years ago, a study by an American life insurance company found that half of people with high mental stress at work often have headaches, colds, indigestion, bronchial inflammation and even pneumonia. Researchers at UCLA found that people who have worked in stressful jobs for 65,438+00 years are five times more likely to develop colon and rectal cancer than those who like their jobs.

An American sociological magazine reported that married people live healthier, happier and happier lives than single people, among which men benefit the most. Harmonious sex life can also keep people young and energetic. Researchers at the University of Edinburgh have found that having sex twice a week or so can keep people young through the release of physical strength and feelings, as well as the pleasure brought by sexual pleasure. Scientists also warned that the morbidity and mortality of divorced people are high.

Let the body moderately "low temperature"

"Cold has three points, long life and health." Apples can be kept fresh for a long time by refrigeration. This principle applies equally to people and animals. The higher the temperature, the faster the metabolic process of the human body and the faster the aging. Scientists believe that if the body temperature of warm-water animals (including humans) is lowered by 2℃ ~ 3.5℃, their life span can be doubled. The body temperature of 37℃ was formed in order to adapt to the natural environment in human evolution, and now it has become an obstacle to the road to longevity. At normal body temperature, the human heart beats 72 times per minute. At the age of 70, his heart beat about 2.6 billion times in his life. If his temperature drops a little, his heart rate can be reduced to 60 to 50 beats per minute. In this way, if the total number of heartbeats remains unchanged, its life can be greatly extended. Therefore, medical experts suggest that as long as people insist on swimming and cold water bath, don't do strenuous exercise for a long time, wear less clothes, balance the calories in the diet and keep a cool head. They can reduce the body temperature to a certain extent, even at night, it is best to keep the indoor temperature low.

Maintaining moderate hunger "makes people old" and "eating stupid will make them stupid". Some people mistakenly believe that the more you eat, the better, and the more nutrients you get. In fact, the diet pays attention to balanced nutrition and reasonable collocation. Dietetic experts have found that excessive eating will make the brain precocious and accelerate people's aging. Professor Ray Wolford of the University of Los Angeles obtained the scientific proof that "hunger can make youth last forever" from mice for the first time. Mice fed less food live twice as long as mice fed as much as they can. Wolford believes that human beings can live longer by adopting this "diet of eternal youth". Only eating 70% to 80% of him per meal can ensure that the brain function can be fully exerted, and the memory ability, understanding ability and thinking and analysis ability can be in an ideal state. Therefore, you should eat moderately until you are half full. Never eat all day, let alone overeat. Generally speaking, it is advisable to keep the daily calorie intake between 1200 ~ 1500 calories.

Keep enough sleep When people are having fun or working hard, it is easy to forget that their bodies need rest. Moderate sleep, that is, 7-9 hours of sleep every night, can make people look energetic and feel energetic. In addition, adequate sleep can prolong life. According to a study by a medical department in California, the death rate of people who sleep less than 6 hours a night is 70% higher than that of people who sleep 7-8 hours a night.
