## How Sweat Rate Is Calculated

### Formula

**Sweat Loss (oz) = Weight Lost (lbs) x 16 + Fluid Consumed (oz)**

**Sweat Rate = Sweat Loss / Exercise Duration (hours)**

Each pound of weight lost during exercise represents about 16 oz (473 mL) of sweat.

### Hydration Guidelines

- Replace 80% of sweat losses during exercise.
- Dehydration above 2% of body weight impairs performance.
- Dehydration above 4% can be dangerous.

### Factors Affecting Sweat Rate

- Temperature and humidity
- Exercise intensity
- Body size
- Fitness level (fitter athletes sweat more efficiently)
- Genetics
