Sedentary lifestyle characterised by much sitting and little physical exercise is a silent killer.

This is according to Dr Yinka Awogun, a Physiotherapist at the National Hospital, Abuja.

He emphasises the need for Nigerians to be cautious of sitting for long hours to reduce the risk of non-communicable diseases (NCDs).

Dr. Awogun believes that staying active is the cheapest and greatest way of preventing such ailments.

The World Health Organization says people who are inactive, use tobacco, eat unhealthy foods and abuse alcohol are likely to have these ailments:

1.    Cardiovascular diseases - Generally refers to conditions that involve narrowed or blocked blood vessels that can lead to a heart attack, chest pain (angina) or stroke.

2.    Cancers - Abnormal growth of cells.

3.    Chronic respiratory diseases - Diseases of the airways and other parts of the lung.

4.    Diabetes - A disease in which the body’s ability to produce or respond to the hormone insulin is impaired, resulting in abnormal metabolism of carbohydrates and elevated levels of glucose in the blood.

If your job requires that you sit for long hours, one thing that you must ensure you do, according to Dr. Awogun, is to maintain some degree of activity.

Even if it is simply taking walks round your house; JUST DO IT!

"20 to 45 minutes of exercise is good enough twice a week. It will go a long way to prevent a lot of problems that could come in with diabetics, obesity, cardiac problems, arthritis earlier in life," he added.
