10Excessive Sweating
Sweating excessively, particularly when you do not work out or involve in any physical activities, would be a warning sign of a heart attack and other heart issues. Pumping blood through blocked arteries often requires the heart to work harder. Thus, the body will sweat more to keep the body temperature down during extra exertion. Clammy skin, night sweats, and cold sweats are typical symptoms that would indicate a possible heart attack. [10]
