2.4 Staying Hydrated
Notes
Your body is about 60% water, and it needs water for temperature control, digestion, carrying nutrients and removing waste.
- Dehydration happens when you lose more fluid than you take in. Signs include thirst, headache, dark urine, dry mouth and tiredness.
- Water is usually the best drink. Milk and unsweetened options also count.
- Sugary drinks, such as soda and many juices and sports drinks, add sugar, and energy drinks contain caffeine that is not recommended for teens.
- You need more fluids during hot weather, illness and exercise.
- Pale yellow urine is a simple sign of good hydration.
- Do not wait for severe thirst; sip fluids throughout the day.
