1. The air should be fresh. Air is the substance that people contact every day. Oxygen in the air accounts for 1/5 of the air volume, which is closely related to human beings and is an indispensable substance for human life. It is best not to have industrial waste gas, dust and smoke produced by smoking around the sports ground, because they will reduce sports ability and be harmful to health. Especially the smoke produced by smoking is very harmful. Smoke contains a lot of carbon monoxide, which will combine with some hemoglobin in the blood after inhalation and lose the normal transportation function of oxygen. It is best to choose a place with fresh air for physical exercise in the morning and evening.
2. No noise interference will affect the concentration of exercisers' attention, affect the diffusion of exercise, and the exercise effect is not good, which may also cause injury accidents. Experiments show that noise reduces exercise efficiency and increases athletes' fatigue. Beautiful music gives people artistic enjoyment, which can not only make exercisers relaxed and happy, but also improve their interest in exercise, strengthen their sense of movement rhythm and exercise effect. It is not unreasonable that music is widely used as accompaniment in sports competitions and mass sports activities.
3. The temperature and humidity should be suitable for the environment. Both temperature and humidity have an effect on exercise. If the temperature is too high and you sweat too much during exercise, dehydration may occur. If you carry out endurance exercise under the scorching sun, you will reduce your working ability and get tired prematurely. When the body temperature rises above a certain limit, heatstroke will occur. Exercise in a cold environment consumes a lot of calories, and in order to maintain a certain body temperature, people may feel cold and uncomfortable. Excessive temperature will affect the evaporation of sweat; Low temperature and high wind speed can promote sweat evaporation. Cold and humid climate and wet clothes have adverse effects on exercise. The human body adapts to the hot environment faster than the cold environment. The hot environment has a greater influence on human physiology than the cold environment. It is comfortable to exercise at the right temperature and humidity. It is also an aspect that the human body adapts to the ever-changing external environment, exercises properly in environments with different temperatures or humidities, strengthens physical fitness and improves its adaptability to the external environment. However, preventive measures should be taken in advance and caution should be exercised.
4. Defending against infectious diseases Under the influence of a large number of exercises, the body is often in a sensitive state due to the overload of the emergency system, and its ability to adapt to various climate changes and its ability to resist certain infectious diseases decline, and various germs around it take advantage of it and are prone to infectious diseases. Therefore, in addition to choosing a good working environment for sports, maintaining a good sports environment is also an important aspect that cannot be ignored, such as maintaining food and accommodation hygiene, adjusting room temperature and ventilation, taking a bath frequently, changing clothes and bask in the quilt.
