Devoted football fans at greater risk of heart attacks - scientists
Devoted football fans experience such intense levels of physical stress while watching their team they could be putting themselves at risk of a heart attack, according to the Centre for the Study of Social Cohesion at Oxford.
The Oxford study tested saliva from Brazilian fans during their historic loss to Germany at the 2014 World Cup. It found levels of the hormone cortisol rocketed during the 7-1 home defeat in the semi-final.
This can be dangerous, increasing blood pressure and strain on the heart, BBC reported.
According to Dr Martha Newson, fans who are strongly fused with their team experience the greatest physiological stress response when watching a match. Raised cortisol can also give people a feeling of impending doom, that their life is in danger or they are under attack.
Therefore, Dr Newson suggested stadiums should dim the lights and play calming music after games.
