Sweat is often seen as a workout badge of honor, but mainly regulates body temperature. Genetics, fitness level, and diet affect how much one sweats. Sweat can benefit skin by retaining moisture and protecting against infections. However, pay attention to body signals; excessive or a lack of sweating may indicate health issues, warranting professional advice. Ultimately, sweat is regular in life and exercise, but listening to your body is key for health and well-being.
