A study done in Finland showed that men who exercised for at least 30 minutes a day decreased their risk of prematurely dying from cancer. The study is published in the British Journal of Sports Medicine.
The subjects were queried about their leisure-time physical activities over a period of 1 year and were subsequently followed up for the occurrence of cancer over a 16 year period.
The reduction in the risk for premature death from cancer was seen in men who exercised for more than 30 minutes every day, and with an intensity that was moderate to high. Examples of activities that can produce this effect are jogging, swimming, rowing, cycling, brisk walking, hiking, dancing, boxing, etc.
What is important to remember is that these activities should be done consistently and should form part of our lifestyle. Exercising regularly should be as essential as eating our meals and not to be done only “when we have time”.
