What kind of living habits are beneficial to physical and mental health?

Teenagers are in the best stage of physical development and learning cultural knowledge. Most parents want their children to be healthy, study well and achieve something in society in the future, which requires a strong body and a smart mind. On the one hand, teenagers should develop good living habits, on the other hand, they should be scientifically matched in nutrition and diet.

First, develop good living habits.

1, have a good breakfast. There has always been a saying that "breakfast is good, lunch is full and dinner is few", but because the morning is the most stressful time, some children are lazy and have no time to eat breakfast. This is very harmful to the brain, because skipping breakfast leads to low blood sugar and insufficient nutrition supply to the brain. Morning is the time when homework is the most, and the energy needed by the brain is not supplied, which will affect homework and brain development in the long run. Fresh milk is best for breakfast. It not only contains high-quality protein, but also contains lecithin necessary for brain development.

2. Ensure adequate sleep. Sleep is a period of rest and adjustment for the brain. Sleep can not only make the cells in the cerebral cortex not fail, but also replenish the consumed energy and achieve a new balance in the process of excitement and inhibition in the cerebral cortex. Good sleep can improve memory. Teenagers should ensure 8 hours of sleep every day. At the same time, you should be careful not to cover your head when you sleep, because when you sleep with your head covered, with the continuous increase of carbon dioxide concentration in the quilt, the oxygen concentration will continue to decrease, and the brain will not get sufficient oxygen supply, which will cause great harm to the brain for a long time.

3. Drink plenty of water. Water is the most important part of the human body. Studies have found that insufficient drinking water is an important reason for the accelerated aging of the brain. Teenagers should drink at least 8 glasses of water every day to ensure their physical needs. Take part in physical exercise. Exercise can not only make bones and muscles strong, but also promote the development of brain and internal organs.

4. Don't use your brain when you are sick. When you are in poor health or suffering from various acute diseases, you should rest. At this time, if you still insist on learning to use your brain, it is not only inefficient, but also easy to cause brain damage.

Second, scientific nutritious diet In order to meet the nutritional needs of the brain, it is best to match nutritious foods with different effects into a balanced diet. Among nutrients and foods, the best brain-nourishing nutrients and foods that play an important role in the healthy development of the brain are:

1, fat is the primary substance for strengthening the brain. Fat plays an important role in the complex and subtle functions of the brain. Providing excellent and rich fat for the brain can promote the development of brain cells and the formation of nerve fiber myelin sheath, and ensure its good function. The best foods are sesame seeds, walnuts, animals raised in nature, other products and nuts.

2. protein is the material basis of intellectual activities. Protein is the main substance that controls the process of brain cell excitation and inhibition, and plays an important role in memory, language, thinking, exercise and nerve conduction. The best food is lean meat, eggs, bean products, fish and shellfish. Fish brain is a good health food.

3. Carbohydrate is the energy source of brain activity. After carbohydrates are decomposed into glucose in the body, they become an important energy source for the brain. The content of main carbohydrates in food can basically meet the needs of the body. Too much sugar will make the brain enter multiple fatigue states, and induce neurasthenia or depression. The best food is miscellaneous grains, brown rice, brown sugar, cakes and so on.

4. Calcium is the substance to keep the brain working continuously. Calcium can keep the blood in a normal weak alkaline state and prevent people from falling into acid fatigue system. Adequate calcium can promote the development of bones and teeth and inhibit the abnormal excitement of nerves. Severe calcium deficiency can lead to bad temper, hyperactivity, decreased disease resistance, inattention, mental retardation and even mental retardation. The best foods are milk, kelp, bone soup, small fish, seaweed, wild vegetables, bean products, shrimp skin, fruits and so on.

Lifestyle and physical and mental health

-Professor Hong Shaoguang, leader of the National Cardiovascular Research Leading Group, gave a lecture in Zhongnanhai.

Heads of state and experts,

I am very happy to discuss "lifestyle and physical and mental health" with you.

According to the definition of the World Health Organization, people are considered middle-aged before the age of 65, young people and old people between the ages of 65 and 74, and formal old people between the ages of 75 and 90. We have middle-aged people and young people here. So, how old should a person's physiological life span be? According to the biological principle, the life span of mammals is five to seven times that of their growth period, while the growth period of human beings is calculated by the time when the last tooth comes out (20 to 25 years old), so the shortest life span of human beings is 100 years old and the longest is 175 years old. The recognized normal life span of human beings should be 120 years old. So how should we spend it?

120 years old, the health of 70, 80, 90, 100 years old is not a dream; Everyone 100 years old should be healthy, which is a normal biological law. But what about the situation now? On average, you should live to 120 years old, but you are only 70 years old, which is 50 years less. 70, 80 and 90 years old should be healthy. Many people are unhealthy in their forties, get coronary heart disease in their fifties, die in their sixties and get sick 50 years earlier.
