Water and Health
Why is water so important?
Most adults lose about 10 cups of water every day through normal body functions including perspiration and breathing. To keep our bodies working properly, we need to replace the water that we lose.
Adults need around 8-12 cups of water per day depending on activity level. This can come from water itself or from other liquids such as low-fat milk, coffee, tea and fruit juices as well as foods.
If you are participating in strenuous activities, try replenishing fluid loss with sports drinks. These are frequently marketed as power drinks and can be beneficial especially if you are exercising in hot humid conditions. The simple form of carbohydrate in the drinks, called glucose is a good energy source for muscles.
How can you avoid becoming dehydrated?
Dehydration can happen in any season, not just summer and not just on hot humid days. In the winter, heated air evaporates moisture on your skin therefore you need to replace fluids. Exercising in cold weather can cause you to perspire and become dehydrated as well. If you are going to be physically active, drink fluids during and after the activity.
2 cups, 2 hours before you exercise
1-2 cups, 15minutes before you exercise
1/2 to 1 cup, every 15 minutes during activity
Weigh yourself before and after a big workout
For every pound you lose after the activity, drink 2 cups of fluid
