If you want to keep running and run comfortably and cheerfully, you'd better wear professional running clothes. If you are just doing general exercise, ordinary sportswear is also acceptable, but you must never run in your daily clothes.
What you wear when running plays a great role in whether you can run happily. No matter in spring, summer, autumn or winter, your clothes should be as light and thin, soft, elastic, and good in air permeability as possible, and it is better to be quick-drying fabric.
Light, soft and elastic clothing will not affect the swing of your arms and the pedaling, bending and striding of your legs when you run. If the fabric is not soft, long-distance running will abrade your skin. Many friends who have run long distances have deep feelings about this. I ran a full marathon before, and the skin on my inner thigh was all worn off. In addition, if you run in an air-impermeable clothes, the heat from your body cannot escape, which is as uncomfortable as running in a raincoat, making you unbearably hot and stuffy. Some people think pure cotton clothes absorb sweat, but they do not know that pure cotton clothes do not dry easily after absorbing sweat, and they stick to your body, which makes you uncomfortable and also makes you easy to catch a cold. Quick-drying clothes are different. They get wet quickly and also dry quickly, do not stick to the body, which makes people feel relatively fresh.
When you go out running, be careful not to wear too much. Once your body starts to warm up, you will feel it is 8 to 10 degrees Celsius higher than the normal temperature. For example, when the air temperature is 13 degrees Celsius, you can just wear a T-shirt and shorts.
