Paragraph 1
Everybody knows that exercise is
to keep us healthy. It lowers the
of heart disease, and helps us to maintain a
weight. It also reduces stress and makes us happier. Doctors say that exercising in cold weather is even better for us. Going for a
or even a swim when it's
or freezing outside has extra benefits for our physical and
health. The reason for this is that the cold gives our heart a more
workout. Dr Angela Pepdjonovic, from the Hospital for Special Surgery in New York, explained why. She said: "Your heart has to work a little
harder to pump
around your body in the cold. This can help to boost your
over time."
