If you’re angry or upset, you might want to simmer down before heading out for an intense run or gym workout.
A large, international study led by McMaster University ties heavy exertion while stressed or mad to a tripled risk of having a heart attack within an hour.
Psychologist Barry Jacobs says the new study serves as a warning.
McMaster’s Dr. Andrew Smyth says while doctors continue to advise regular physical activity for all, he says people should not go beyond their usual routine when they’re emotionally stressed out or angry.
The study is published in the Heart Association journal Circulation.
