Why is physical activity so important in preventing heart disease?

Prevents the thinning of arteries

Explanation:

Throughout our life, we are all told that we should be healthy. We shouldn't smoke too much, shouldn't drink too much, and these statements are fueled by the desire to be healthy.

The main way to stay healthy is through physical fitness. An example would be going to the gym once a week for an hour. It is not the most intensive workout, but it is better than doing nothing.

When we eat food that contains high amounts of cholesterol, not all of the cholesterol can be stored or metabolized. Instead it makes the artery walls thinner, and this in turn leads to higher blood pressure.

If the artery becomes so thin that it blocks blood from going further, this is known as a heart attack.
