Smog weather can easily lead to the decline of respiratory defense function and lung function. People with exercise habits should stop running and walking outdoors, and it is best not to do cardiopulmonary exercise, such as high-intensity running. Because during strenuous exercise, the breathing rhythm is accelerated and deepened, and the harmful gases inhaled into the body will be several times more than usual. Some harmful substances will become more toxic when combined with water vapor, such as sulfur dioxide becoming sulfuric acid or sulfite, chlorine hydrolyzing into hydrogen chloride or hypochlorous acid, and fluoride hydrolyzing into hydrogen fluoride. So the air pollution in foggy days is much more serious than usual. In addition, exercise in foggy days is also easy to induce cardiovascular and cerebrovascular diseases.

Will it be better to go to the park to exercise the air in foggy days?

The answer is no! When PM2.5 seriously exceeds the standard, the adsorption of plants is very weak. Only strong wind or heavy rain can blow away or wash away the smog particles in the air, but plants in parks can't.

Wouldn't it be better to exercise indoors?

The answer is no, air is flowing. When the smog is serious, the indoor PM2.5 index is not much lower than that outside. Unless you have installed a very good quality air purifier, close the doors and windows.

Even if there is no fog, don't exercise on the roadside.

Many runners choose jogging along the road to exercise, which is actually not very healthy. Because. Nowadays, the traffic on urban roads can easily make the dust fly. Running along the road will inhale more harmful gases and particles, which will actually increase the harm to the body while exercising. Therefore, whether running or exercising, it is best to choose quiet and clean places such as playgrounds and parks.

Will interrupting exercise for a few days affect the exercise effect?

Some people are used to exercise, and they are worried that the interruption of exercise for a day or two will affect the exercise effect. In fact, generally speaking, for people who exercise regularly, the benefits brought by exercise, such as lowering resting heart rate, lowering blood pressure and improving metabolism, will gradually disappear after two weeks of interruption. In other words, don't worry too much if you don't exercise for two days or even a week. At the same time, remember that a reasonable rest is as important as exercise. Harmful exercise does more harm than good to your health. It is better not to exercise.

Please pay attention to adjusting your diet when you stop exercising.

If a person consumes 1500 calories a day while losing weight, the calorie intake will also increase due to the increase of exercise during the weight loss process. When it exceeds 1500 calories, the human body will decompose fat and play a role in losing weight. But once you stop exercising, the calories you consume are less than 1500 calories, the excess calories will be stored, and weight loss will rebound. Therefore, losing weight depends on exercise for three points and diet control for seven points. In addition, we should eat a reasonable diet and eat less high-oil, high-sugar, high-calorie and junk food. In addition, three meals a day can be changed to five meals a day, and the total diet can be controlled by eating more and eating less.
