We need to drink enough water each day.
You need water to replace what your body loses through normal everyday functions. You lose water when you go to the bathroom or sweat, and you even lose small amounts of water when you exhale. You need to replace this lost water to prevent dehydration. What is dehydration you asked..? Dehydration means your body does not have as much water and fluids as it should. Dehydration can be mild, moderate, or severe based on how much of the body’s fluid is lost or not replenished. When it is severe, dehydration is a life-threatening emergency.
Your body also needs more water when you are—
- In hot climates.
- More physically active.
- Running a fever
- Having diarrhea or vomiting.
To help you stay hydrated during prolonged physical activity or when it is hot outside:
- Drink fluid while doing the activity.
- Drink several glasses of water or other fluid after the physical activity is completed.
- Whenever 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 due to a health problem, such as kidney disease, or Congestive Heart Failure. If your Doctors / health care provider has told you to restrict your fluid intake, make sure you follow their advice.
