Exercise is important for our health. It lowers the risk of heart disease and helps us to stick to a healthy weight. Doctors say that exercising in cold weather is good for us. It benefits our physical and mental health. This is because the cold gives our heart a bigger workout. A doctor from New York explained why. She said: "Your heart has to work a little bit harder to pump blood around your body. This can help to boost your endurance over time."
The doctor said the body burns calories at a faster rate when it is cold. She said your body works harder to keep warm, so you use up more calories. Physical activity in the cold boosts our metabolism, which helps us lose weight. Another benefit of exercising in the cold is that natural light helps to reduce our stress. Many people have Seasonal Affective Disorder (S.A.D.). This is a sadness caused by the short, dark days of winter.
