You can't eat breakfast before running in the morning because food needs to be digested in your stomach. After breakfast, the whole body's blood will be concentrated in the limbs, and the blood in the stomach is almost zero, so only the stomach wall will directly rub the food in the stomach, and then the symptoms of stomach pain will appear after running in the morning, and gastritis and even gastric ulcer will appear after a long time.

Second, morning running common sense:

1, wear non-slip shoes when running.

The ground is slippery in winter, so people should choose shoes with soft rubber soles as running shoes when exercising, and the tread pattern of the soles should be wide and deep. Because the dense sole pattern can't play the role of anti-skid, and the hard rubber sole will become harder in cold air, people will lose control of their feet during exercise, just like wearing skis, which will lead to accidents and dangers.

2. Pay attention to the running time rather than the distance.

Running in the snow or skating area will take more time and energy than usual. Therefore, experts suggest that winter running should pursue exercise time, not exercise distance. In addition, the speed of exercise should also be reduced, so that the body can be stretched gradually, which is conducive to further exercise.

Go against the wind first, and then go home with the wind.

Pay special attention to the running direction when exercising in windy conditions. If you run with the wind at first, you will get some fine sweat on your body, so you will risk catching a cold when you run back against the wind. So experts suggest: run against the wind first, and then go home with the wind.

Extended data:

It is best to drink a glass of milk and eat a fruit for breakfast in the morning run. Pay attention to drinking water before morning exercise. When drinking water, it is generally best to drink a cup of cold boiled water of about 250CC, and the water temperature is about 15℃. In this way, the temperature can be lowered in summer to quench thirst, and water cooling in winter will not stimulate the mouth and stomach. Drink water slowly to avoid abdominal distension. After drinking, you can take part in morning exercises in 10 minutes. You need to rest after the morning run 15-30 minutes before you can have breakfast. You should ensure a good breakfast, and generally choose light and nutritious foods, such as soybean milk, eggs, steamed bread and fruits.
