Try brisk walking, running, cycling, dancing, swimming - or any activity that makes you slightly breathless. To stay fit, you'll need to exercise for about 30 minutes per day - and keep it up every week. Your heart is the muscle that pumps vital supplies of oxygen-rich blood around your body. Regular exercise makes your heart grow stronger, so that it can pump more blood with each beat. This means that your heart does not have to work so hard to do its job.
Smoking is one of the main factors which cause heart disease.
If people in the United Kingdom did not smoke cigarettes, about 10,000 fewer men and women of working age would die from heart attacks each year. The risk of a heart attack rises with the amount smoked. Smoke harms your heart because chemicals in the cigarette smoke damage arterial linings leading to coronary heart disease. Several recent reports indicate that the risk of heart disease is reduced by regular consumption of small quantities of alcohol. But if you seldom or never drink alcohol, you should not change your habits.
