The sun doesn't come out because of running or exercising in the morning. Plants are doing breathing exercises, not photosynthesis. They absorb oxygen and release carbon dioxide. The human body naturally cannot absorb fresh oxygen, and it is prone to hypoglycemia and even dizziness.
In addition, if people do more intense physical exercise immediately in the morning, the joints, muscles, heart and brain of the body will suddenly enter a state of tension from the relaxed state after sleep, which is difficult to adapt for a while, and it is easy to get injured or lead to acute diseases. When you get up in the morning to exercise, don't do too much exercise. It's better to walk.
According to the research, the best running time is from 9: 00 am to 10. The air quality is relatively best at this time. For those who go to work and go to school, exercising in the morning is a helpless choice, but for those who have the conditions to choose the exercise time, such as the elderly, it is best to exercise at this time. However, the following points should be noted.
1. Morning exercise on an empty stomach
Many people go outdoors to do morning exercises on an empty stomach after getting up in the morning, thinking that this can reduce weight more effectively. In fact, this is a misunderstanding, and morning exercise on an empty stomach has certain harm.
First of all, morning exercise on an empty stomach can't effectively burn fat and achieve the purpose of losing weight, because the decomposition of fat needs the participation of sugar, and the sugar content in the body is insufficient after getting up in the morning, so that fat can't be fully burned, but it will turn fat into ketone bodies and dissolve them in the blood, causing acidosis. But also the workload of the liver. After getting up in the morning, eat some food or a glass of milk properly before exercise.
2. Drink water before morning exercise.
After a night's sleep, a lot of water in the body is lost through evaporation and metabolism, and the body is in a state of high water shortage. At this time, the blood is thick, the blood volume is reduced, the blood flow is slow, and the viscosity is high. If you exercise outdoors without drinking water after getting up, the waste in your body can't be excreted, and your blood is in a sticky state, which may easily lead to cardiovascular and cerebrovascular diseases such as cerebral thrombosis. Drinking a cup of boiled water on an empty stomach in the morning is good for your health, but don't drink water 20 minutes before exercise. It is best to exercise for 20 minutes after drinking water in the morning, otherwise it is easy to get angry and get stomach trouble.
3. It is not advisable to eat immediately after morning exercise.
Some people are in a hurry to go to work and school in the morning and are used to eating immediately after morning exercise. This habit is unhealthy. After exercise, most of human blood is in the blood vessels on the body surface, and the blood flow in the gastrointestinal tract is relatively small, which is not conducive to the absorption of food. If you eat at this time, you are prone to gastrointestinal diseases such as indigestion.
It is best to have breakfast half an hour after morning exercise, and you can drink a little hot coffee or milk before, which will help the gastrointestinal function to recover as soon as possible.
4. It is not advisable to take a deep breath outdoors in the morning.
When exercising in the morning, many people like to take a deep breath and think that the air in the morning is clear and cleanest. In fact, it is not appropriate to take a deep breath outdoors in the morning, because it is harmful to health. Because the ground temperature is low and the atmospheric pressure is high in the morning, the harmful gases and impurities in the air near the ground can't rise to the high altitude and be discharged, and they are pressed by the atmospheric pressure to move near the ground. Therefore, the air in the morning is often the most polluted in a day. If you take a deep breath in the morning, it is tantamount to inhaling harmful gases in a big mouth, which is extremely harmful to health.
5. Avoid outdoor sports in foggy days.
Outdoor sports should be avoided in foggy days for the following reasons:
First of all, in foggy days, the water vapor is heavy and the air is cold and humid. When it comes into contact with people's skin, the pores will shrink when it is cold, which will hinder the heat dissipation generated by exercise and lead to the imbalance of heat balance in the body, which will not only affect the exercise effect, but also make people feel weak and prone to illness.
Secondly, fog beads contain a lot of harmful substances such as dust and pathogenic microorganisms. When you exercise in fog, people's breathing will be accelerated and deepened with the increase of exercise. A large number of harmful substances in fog will be inhaled into the body, but exercise will become an invisible killer, making harmful substances harm the respiratory system, causing dyspnea, chest tightness, palpitations and other adverse symptoms, and pathogens will also take advantage of it and endanger human health. So the air pollution in foggy days is much more serious than usual. When you exercise in foggy days, you will inhale a lot of these toxic substances.
