Have you ever noticed how lifeless a houseplant looks when you forget to water it? If you add just a little water, it seems to perk back up. Water is just as necessary for the healthy function of our body. Water makes up more than two-thirds of the weight of the human body.
Water helps our body:
- Keep a normal body temperature
- Lubricate joints
- Protect the spinal cord, organs and tissue
- Get rid of wastes through urination, bowel movements and sweat
If you don’t drink enough water you’ll become dehydrated, and your body fluids will be out of balance. Dehydration occurs when the amount of water leaving the body is greater than the amount of water taken in. Your body loses water through normal everyday functions when you use the bathroom, exhale and sweat. Your body needs more water if you’re exercising, running a fever, in warm weather or if you’re experiencing diarrhea or vomiting.
Thirst is a signal that you’re already on your way to dehydration. Other signs and symptoms of dehydration may include:
- Fatigue
- Headache
- Dry mouth
- Muscle weakness
- Dizziness
- Urine that appears more yellow in color
Make sure you’re sufficiently hydrated before, during and after time spent in warm weather or during exercise. If you’re a healthy adult, you can generally use your thirst as an indicator if you need more water. Individuals at a higher risk of dehydration include children, older adults and people with special needs, so be sure to help keep them well-hydrated.
If you have a health condition that requires fluid restrictions, be sure to follow the advice of your healthcare provider.
