Walking too fast in hot weather will make it difficult to breathe.

Insufficient blood supply to the heart leads to palpitation, followed by decreased oxygen content and red blood cells in the blood, decreased lung function and difficulty breathing. Generally, people who don't exercise regularly will have this kind of performance after strenuous exercise, or after heatstroke, dehydration and sedentary in hot weather, but it is difficult for people to notice because of the short onset time. It is difficult to draw a conclusion now, but it will cause a heart attack after a long time. Of course, this is also related to the diet structure. Eating high-fat and high-calorie food every day will cause blood vessel blockage and increase the frequency of attacks. Because the disease does not attract the attention of patients because of the short attack time, the mortality rate is very high. Not long ago, it was reported on the Internet that the super-responsible driver stopped the bus before he died. But the deceased and his family did not know that they were sick. I hope everyone can help me treat and prevent as soon as possible!
