You can't forget to water a plant and then drown it in fluid to make up for it. The same is true for your body. Your body doesn't store water to use for later. You must hydrate continuously at the right levels all day to replace fluid loss. A general rule of thumb is to consume about 1 oz. of fluid per 2 pounds of body weight, plus what you sweat out during exercise.
Need to know how much water you need to drink? Follow the steps below to calculate your sweat rate:
- Weigh yourself without clothes on before exercising for (ideally) one hour.
- After your run strip down and weigh yourself again.
- Assuming you did not use the toilet or consume any fluids during exercise, your weight loss is your sweat rate.
- For each pound lost, you lost approximately 16 oz. of fluid. If you drink any fluids or use the rest room between the two weight samples, you'll need to include both of these estimated weights in your calculations.
- Add fluid consumed to the amount of weight lost. Subtract estimated bodily void weight from the total weight lost.
- Be sure to record the heat and humidity conditions in your sweat test.
For best results, repeat the test in cool and hot conditions. Repeat the test for swimming, running and cycling because sweat rates will vary for each sport and vary with environmental conditions.
