Students usually sit quietly in the classroom and bend over to study. Being in this posture for a long time and not taking part in physical exercise will often lead to various diseases. Such as insufficient blood supply, neurasthenia, thoracic stenosis, muscle weakness, heart disease and constipation. Therefore, students should often take part in physical exercise, because physical exercise can make the heart and gastrointestinal tract get good exercise and make students energetic. At the same time, physical exercise is an active rest, and brain cells have their own division of labor. During physical exercise, the mental cells that manage muscle activities are in an excited state, while the nerve cells that think about problems are in an inhibited state and get a good positive rest.
College students are a special group. We often neglect physical exercise because we are busy with heavy schoolwork and other things. In addition, our usual study and life make us unable to move for a long time, so we need physical exercise to keep fit.
