Researchers said that a person may run the risk of a fatal heart attack or myocardial infarction and heart disease, if he is exposed to more than usual. 

The researchers reported that excessive sweating is one of the early warning signs of a heart attack.

Whereas if some arteries of the body are clogged with fatty deposits, the heart needs to work harder to ensure that blood is pumped throughout the body.

As a result of the additional work, the body begins to sweat to keep its temperature low, stressing that if a person notices that he is sweating a lot without any apparent reason, he should consider talking to the doctor. 

"It is better to seek emergency medical treatment ... sweating more than usual, especially if you are not exercising or being active, it could be an early warning sign of heart problems," the researchers added.

They continued that "pumping blood through the blocked arteries requires more effort from the heart, so the person sweats more in an attempt to keep your body temperature low during the additional effort."

However, just because a person sweats excessively, this does not necessarily mean that he suffers from a heart attack. Excessive sweating, or hyperhidrosis, is actually a very common condition that affects people of all ages.

It can happen as a side effect of another medical condition, or without any apparent cause at all.
