sweat loss

Sweat loss occurs when your body produces sweat to help regulate temperature, primarily through your skin. When your body heats up from activity or hot weather, sweat glands release fluid, which evaporates and cools your skin and blood. This process helps prevent overheating but also causes fluid and electrolytes like sodium to leave your body. Losing too much sweat without replacing fluids can lead to dehydration, characterized by symptoms such as thirst, dry mouth, and fatigue. Proper hydration is essential to maintain your body's temperature control and overall health during physical activity or in hot environments.
