Exercise is a Chinese vocabulary, pronounced duàn liàn, which is defined as physical activity that uses planned, structured and repeated physical activities to improve the health of one or more body parts. Make the body strong through exercise, and cultivate virtues such as courage, wit and safeguarding collective interests.
The basic explanation originally meant to strike and forge swords, and extended to improve consciousness and work ability through productive labor, social struggle and work practice. Refers to forging or smelting, making the body strong through exercise, cultivating moral qualities such as courage, alertness and safeguarding collective interests. Through productive labor, social struggle and work practice, we can improve our consciousness and work ability, that is, exercise and long-term exercise.
In the cold winter, many people choose morning exercises to enhance their immunity. However, isn't outdoor fitness the sooner the better? Relevant health experts suggest that outdoor fitness in winter should be carried out after sunrise.
It is understood that the ground temperature is low before sunrise in winter, and the content of pollutants such as carbon monoxide and carbon dioxide released in the air in the morning is high. In addition, harmful pollutants such as nitrogen oxides, hydrocarbons and lead in automobile exhaust also gather on the ground. If people get up early to exercise, they will inhale a lot of smoke and toxic gases. Long-term exercise in this environment may lead to fatigue, dizziness, pharyngitis and other diseases, which are harmful to the body.
Some people are used to exercising on an empty stomach in the morning, while others advocate exercising after meals in the evening. When is the best time to exercise? We think it is more appropriate to start exercising half an hour or an hour after breakfast or dinner. Exercise before meals may cause blood sugar fluctuations, hypoglycemia may occur because of delayed meals, and hyperglycemia may occur because of no medication. Of course, it may also be due to Su Mujie's reaction that blood sugar is low first and then high, so it is best to put exercise time after meals.
In order to avoid affecting the function of digestive system, it is best to do physical exercise more than half an hour after meals. Physical exercise after dinner is worth advocating, because most people in China eat more after dinner, and most people just watch newspapers or TV programs after dinner, and seldom do physical activities, which is very unfavorable for lowering blood sugar and losing weight.
