«Our Health»
Our health depends on many things: our physical activity, the food we eat and our good and bad habits. Although a lot of people are interested in staying healthy, not many people do very much about it. Modern way of life when people have little physical activity, use cars instead of walking, watch television and work on computers for many hours is quite dangerous for their health. People’s health also influences their mood.
There are many opportunities to stay healthy and be fit and one of them is going in for sports. But you needn’t be a professional sportsman. Just simple regular exercises give you energy and help you feel and look better.
Exercises that involve repeated movements such as are walking, jogging or swimming are the best. Bending and stretching which are practiced in aerobics or yoga make your body flexible and light. The cheapest and most popular sport is jogging. If you don’t have time for it, make small changes like using stairs instead of the lift or walking or cycling instead of taking the bus and it can help you to improve your health and make you a more active person.
Also it is very important to get rid of bad habits. The worst ones are smoking and drinking alcohol. Smoking doesn’t only causes heart and lung problems but also makes your teeth yellow and skin unhealthy.
Food we eat also influences our health. A lot of people like drinking Coca-Cola and coffee and enjoy pizza and hamburgers. But what is tasty is not healthy. You should avoid eating in fast food restaurants and make it a rule to cook meals at home using organic food as much as possible.
Only a healthy man can enjoy his life, work well and be happy. There are proverbs “Health is better than wealth” and “Early to bed and early to rise makes a man healthy, wealthy and wise”.
