1. The impact of lifestyle on health

What is lifestyle?

Lifestyle refers to the various behavioral habits that people follow in their daily lives. Including eating habits, living habits, daily life arrangements, entertainment methods and participation in social activities.

1. Over the past 40 years, what changes have occurred in the main types of diseases that cause death among urban residents in my country?

In 1957, the top three leading causes of death among urban residents in my country were respiratory diseases, acute infectious diseases, and tuberculosis. In 2003, respiratory diseases dropped from the first place to the third place, with acute infections disease and tuberculosis ranked after 7th. On the contrary, heart disease, cerebrovascular disease and malignant tumors, which ranked fifth, sixth and seventh among the causes of death in 1957, rose to fourth, second and first respectively in 2003.

2. Why did this change happen? What do these changes indicate?

Since diseases such as respiratory diseases, acute infectious diseases, and tuberculosis are mainly caused by poor living environment and nutritional conditions, cardiovascular and cerebrovascular diseases and malignant tumors are not only affected by genetic factors, but also mainly related to psychological factors such as stress and anxiety. and unhealthy lifestyle.

Changes in causes of death indicate that as people's living standards improve, psychological factors and behavioral factors play a vital role in health.

3. "Some people smoke all their lives and still live to be eighty or ninety years old. This shows that smoking is not harmful to people." Can you make a strong rebuttal to this?

The conclusion that "smoking is harmful to health" is reached through statistical analysis of a large amount of survey data. In other words, compared with non-smokers, smokers are more likely to suffer from respiratory diseases and related diseases. For example, smoking is 220 times more likely to cause lung cancer than non-smoking. There are only a very small number of people who "smoking all their lives and still live to be eighty or ninety years old", which does not mean that the harm of smoking is not serious.

2. Unhealthy lifestyle

1. Smoking, especially those who smoke more than 20 cigarettes a day, increases the risk of chronic diseases rapidly.

2. Unhygienic eating habits absorb too many calories, saturated fatty acids, and cholesterol, leading to obesity, hyperlipidemia, and other diseases.

3. Drinking too much alcohol.

4. Lack of exercise leads to decreased cardiorespiratory endurance, weakened muscle strength and increased average muscle fat mass.

5. Overloaded, overworked, burning the midnight oil and lacking rest.

6． Chronic troubled emotions, anxiety, depression, nervousness, and interpersonal disharmony lead to chronic fatigue and energy exhaustion.

7. Drivers drinking cause traffic accidents.

8. Dirty food and drinking water can cause disease infection.

9. Dependence or addiction to certain drugs.

10. No treatment of toxic waste, such as hospital waste containing sources of infectious bacteria.

11. Insomnia or sleeping less than 7 hours. According to statistics, most insomniacs are prone to angina pectoris symptoms.

2. Keep up with physical exercise

Life requires exercise. Too little or too much exercise is not good for health. Individuals can choose the appropriate type of exercise based on their age, physical condition and environment.

The form of exercise is not important. What is important is to do it according to your ability, step by step and persevere. The simplest exercise is brisk walking, walking 3 kilometers every day, or doing other exercises for more than 30 minutes. Exercise at least 5 times a week. The appropriate intensity of exercise is when your heart rate reaches 170 minus your age. It is best to maintain this state of accelerated heart rate and body heat for more than 15 minutes.

When tobacco is burned, harmful substances such as nicotine and tar in the smoke enter the human body and can induce a variety of respiratory diseases and even lung cancer.

1. Low-concentration alcohol (less than 0.25%) can promote the heart rate of water fleas, while high-concentration alcohol can inhibit the heart rate of water fleas. This is because low-concentration alcohol can promote the metabolism of water fleas and increase nerve excitability to a certain extent, while high-concentration alcohol mainly anesthetizes nerves. Tobacco extract promotes the heart rate of water fleas, because tobacco contains ingredients such as nicotine (such as nicotine), which excites nerves.

2. The possible harms of alcoholism to human health include: alcohol can damage the human heart and blood vessels. Alcoholism can cause the brain to be over-excited or paralyzed, causing neurasthenia and mental retardation, which has a great impact on study and work.
