Exercises lead to a healthy body. But it is believed that rigorous exercises are often the reason behind sudden cardiac arrests or sudden heart-related deaths. However, a team of researchers at the University of British Columbia defies the same.

It is being said that the belief is not a fact, but a myth. And exercises should never be held responsible for such kinds of deaths. Sudden cardiac deaths usually can happen anytime and can occur in people either working on their computer or sleeping.

Also, the ones doing daily activities may suffer the same and a TV watcher is equally at risk. The study was presented at the 2012 Canadian Cardiovascular Congress on Monday, which says an athlete collapsing down and facing death of a cardiac arrest is merely a bad happening.

The 2008 Ontario coroners' reports were analyzed by cardiologist Dr. Andrew Krahn and colleagues and the same led them discover some 174 presumed sudden deaths in two-40 years aged people. And amid these, 18 to 40-year-olds had suffered a heart disease. 72% of all died at home, while 74% were not diagnosed with heart ailment while alive.

"I would advocate for careful screening of people who faint, using questionnaires and education of healthcare professionals", said Dr. Krahn.
