Exercise is like magic for our bodies. It does wonders for our physical and mental health.
Physically, exercise helps to build strong muscles. When we exercise, our muscles work hard, and over time, they become stronger. It also improves our bone health. Weight - bearing exercises, such as walking, running, and lifting weights, help to keep our bones strong. This is especially important as we get older.
Exercise is great for our heart too. It makes our heart work better and stronger. A strong heart can pump blood more efficiently around our body, which helps to keep us healthy. It also helps to lower our blood pressure and reduce the risk of heart disease.
Mentally, exercise can make us feel better. When we exercise, our body produces chemicals called endorphins. These endorphins are like natural painkillers and mood - boosters. They can make us feel happy and relaxed. Exercise can also help us sleep better. People who exercise regularly often find that they fall asleep more easily and have a better night's sleep.
