It's not that hot out, but you find yourself sweating profusely. Not to overdramatize this situation (I mean, maybe you had some spicy kung pao chicken for lunch), but excess sweating could be a warning sign of heart failure in men and women.
Heart attack victims are often known to sweat a lot just before and during a heart attack. A major portion of the body's nervous system, the sympathetic nervous system, controls sweating throughout our bodies. When a heart attack kicks in, the sympathetic nervous system gets activated, causing the sweat to pour out.
