It is said that plants exhale a large amount of carbon dioxide after a night of metabolism, so the concentration of carbon dioxide in the woods is relatively high in the morning, and some dust is also floating in the air, which is not good for human health. In addition, people's blood pressure is higher in the morning, which can easily lead to problems. In fact, whether to exercise in the morning depends mainly on the purpose of exercise. If the purpose is to lose weight or to increase memory of motor skills, the morning is very good . When people wake up in the morning, they have almost consumed most of the energy they ate last night. If they exercise without eating at this time, it will lead to one result - "burning" fat. Because the energy is gone in the morning, there is still some glycogen in the liver. When the concentration of this glycogen drops to a certain level, fat "burning" will become the dominant energy supply, making weight loss possible. Therefore, morning exercise has special benefits for weight loss and preventing and treating fatty liver . In addition, it is easier to master aerobics, ballroom dancing, Tai Chi... any skill in the morning than at other times. Therefore, in a sense, the health benefits of exercising in the morning are greater. The ancients believed in "getting up and dancing upon hearing the cock-crow" and generally chose to exercise in the morning. As for the high carbon dioxide content in the morning air and serious pollution, this is not the main reason. In fact, pollution from car exhaust and other sources during the day is also very serious, and can also release lead, heavy metals and some chemical wastes, such as benzene. High blood pressure in the morning can be adjusted with medication. Therefore, when is the best time to exercise? It is not absolute. It also depends on the person. No matter what kind of exercise you do, especially for middle-aged and elderly people, from the perspective of physical exercise, it is suitable to do whole-body activities. For example, swimming, running, walking, all of these are fine, and doing gymnastics is also fine. But it has to reach a certain amount. There is a saying of "three, seven". The so-called "three" means that each exercise should last more than 30 minutes. If the exercise time is less than 20 minutes and the intensity is not very high, it will probably consume some blood sugar in the blood circulation at most, but it will not help to lose weight or consume excess fat accumulated in the body. It should be noted that it is definitely not a good idea to exercise immediately after eating a full meal. This is because after a meal, your blood is concentrated in the stomach to digest food. |
