Don’t be afraid of the sun when running in summer, running in the sun has amazing effects!

If you ask which season is the best for running, many people would think spring and autumn. Indeed, the climate in spring and autumn is cool, neither hot in summer nor cold in winter, and it is very comfortable to run. But what you may not know is that although running in the summer will be exposed to the sun and wind, it also has many benefits.

1. Help the body synthesize vitamin D

When running in the sun, your skin can help the body produce vitamin D under the sun, which not only helps calcium absorption and prevents osteoporosis. In addition, according to research, vitamin D can reduce the risk of breast cancer, colorectal cancer, and prostate cancer after it is produced into 25(OH)D by the liver! Of course, if you are exposed to the sun too much, you should also pay attention to the risk of skin cancer.

2. Perspiration improves metabolism

Running in the summer and sweating a lot can improve basic metabolism and strengthen the excretion of body waste. In addition, according to research, after sweating, if there is wind with a speed of more than 3 meters per second, the body will feel cool. 3 meters per second is equivalent to 10.8 kilometers per hour, which is a pace of 5 minutes and 30 seconds per kilometer. So as long as you run faster than this speed, you can feel naturally cool!! (But this speed seems to be something that ordinary people can't achieve...) In addition, many people are worried about the problem of sweat odor. In fact, sweat itself does not smell, but the trace sugars and nutrients in the sweat are decomposed by bacteria on the surface of the skin, which will produce odor. Therefore, please take off your wet clothes and dry your body sweat as soon as possible after running. This will not only reduce the problem of odor, but also prevent you from catching a cold! Many people think that they are less likely to catch a cold when the weather is hot. In fact, because we sweat a lot in summer, our whole body is wet after running, and we are more likely to catch a cold when the wind blows!
