I always thought that it was a good idea to hit the gym if I was angry or upset. I thought it would be a good way to get rid of some stress.

But, that is not the case at all. In fact, it could be deadly. A new study reveals that the most dangerous time to exercise is when you're angry or upset.

Why? Heavy exertion, such as an intense run or gym workout, while you are stressed or mad triples your risk of having a heart attack within one hour, according to research from Canada's McMaster University.

Exercising when your emotions are overwrought can be physically harmful.

"Being angry or upset doubled the risk of suffering heart attack symptoms within one hour. Heavy physical exertion doubled the risk of suffering heart attack symptoms within one hour. Being angry or upset and heavy physical exertion tripled the risk of suffering heart attack symptoms within one hour."

The study warns that the risk is greatest between 6PM and Midnight.
