Hot-tempered people are risking heart attacks and strokes. Outburst of anger often happens just before the heart attack. The Harvard School of Public Health researchers revealed the changes, which take place in about two hours after the outburst of anger. People with heart conditions and other risk factors should remember this.

As BBC reports, within the first two hours after the outburst of anger the risk of heart attack jumps nearly five times, and the risk of stroke - more than three times. Moreover, the effect is cumulative. Five episodes of anger a day would result in around 158 extra heart attacks per 10,000 people with a low cardiovascular risk per year, increasing to about 657 extra heart attacks per 10,000 among those with a high cardiovascular risk.

In whole the absolute risk is not as high, but people with a hot temper must be cautious about the problems with heart and blood circulation. Experts know that chronic stress can contribute to heart disease, partly because it can raise blood pressure but also because people may deal with stress in unhealthy ways - by smoking or drinking too much alcohol, for example. Experts recommend hot-tempered people practice yoga and other relaxation programmes.
