Your body has daily fluid needs. Ever notice how lifeless a houseplant looks when you forget to water it? Just a little water and it seems to perk back up. Water is just as essential for our bodies because it is in every cell, tissue, and organ in your body. That’s why getting enough water every day is important for your health.
Healthy people meet their fluid needs by drinking when thirsty and drinking fluids with meals. Keep in mind that if you’re outside in hot weather, or are doing vigorous physical activity, you will need to make an effort to drink more fluids.
Most of your water needs are met through the water and beverages that you drink. You can get some fluid through food. For example, broth soups and other foods that are 85% to 95% water such as celery, tomatoes, oranges, and melons.
You need water to replace what your body loses through normal, everyday functions. Of course, you lose water when you go to the bathroom or sweat, but you even lose small amounts of water when you exhale. You need to replace this lost water to prevent dehydration.
To help you stay hydrated during prolonged physical activity or when it is hot outside you should drink fluid while doing the activity. Drink several glasses of water or other fluid after the physical activity is completed. When you are participating in vigorous physical activity, it’s important to drink before you even feel thirsty. Thirst is a signal that your body is on the way to dehydration
Some people may have fluid restrictions because of a health problem, such as kidney disease. If your healthcare provider has told you to restrict your fluid intake, be sure to follow that advice.
