People's mental state will be affected by cortisol levels. Generally speaking, after 1 1 in the morning, the cortisol level in our body begins to rise, and it will rise to a higher level around noon 12, which is why we feel sleepy at noon and need to take a nap.
But for many married office workers with children, noon has become their only free time. There is no need to choose this time for exercise. If you exercise indoors, this is a good choice, because your body temperature is higher and your flexibility is higher at noon.

Matters needing attention
1, do enough warm-up preparation before exercise.
Generally speaking, when you feel that you are sweating, you should say that you have done enough warm-up. You can use some indoor sports equipment to warm up, or you can warm up outdoors, such as jogging. When doing warm-up running, don't increase the speed to a very high speed at once, otherwise you will have difficulty breathing, and in severe cases, you may cause respiratory diseases.
2. Wear layered clothes.
Many people think that you can only wear sportswear for outdoor sports because it won't be cold when you exercise. However, the human body generates more heat during exercise, which is only in the middle, and it is very vulnerable to the influence of external temperature when connected in series.
Therefore, at the end of rest and exercise, clothes should be added in time. That is to say, with the increase of exercise and perspiration, take off your clothes slowly and put on your clothes immediately after exercise. Don't wait for the sweat to dry before adding clothes, so the chances of catching a cold are nine times out of ten.
3. Replenish water in time before and after exercise
Outdoor sports in winter need as much water as in summer. Drinking water can be ordinary water or sports drinks. On the other hand, in cold weather, many people want to drink a cup of hot coffee or chocolate before going out for exercise, which is unscientific, because it contains caffeine, which will make people lose water and is the most taboo drink before exercise.
