Did you know that your body is mostly made up of water? There’s a reason for that!
Water is used for:
- Removing wastes
- Transporting nutrients
- Regulating your body temperature and blood pressure
- Helping to keep your skin, joints, and organs healthy 
Do I really need 8 cups a day?
- Healthy adults generally require up to 9-12 cups of fluid a day (depending on your sex, age, activity level, and even the weather) .
- Note: Fluid is not just water, but can be food and drinks that contain water such as milk, tea, soup, etc.
People at risk:
Certain groups of people are at higher risk of becoming dehydrated:
- The elderly
- Young children and infants
- People who work outdoors
Indicators of dehydration:
Your body loses fluids during exercise and in hot conditions through sweat, so it’s important to replenish/restore these losses by drinking water throughout the day. Indicators that your body is already dehydrated and needs water include:
- Feeling thirsty
- Dark urine
- Not urinating very much
- Feeling dizzy
- Delirium (mostly in the elderly)
- Dry skin and lips
Can sugar-sweetened beverages (like juice, pop, and chocolate milk) give me the fluid I need?
Sugary drinks definitely do contain water, but the amount of sugar (and in the case of pop, the acid too) makes water the best choice to stay hydrated. Limiting sugar in your diet has lots of positive effects on your health, and avoiding pop (even diet ones!) can save your teeth from erosion.
Will caffeine make me dehydrated?
Try to limit your caffeine intake to less than 3 cups a day (400mg of caffeine/day) . This is the amount that research has shown that does not cause your body to be dehydrated or make more urine (especially if you drink caffeine regularly).
Tips to stay hydrated:
- Keep a reusable water bottle handy
- Have a cup of water when you wake up and go to bed
- Add fun flavours to your water like cucumber, herbs, lemon, etc
- Have a glass of water with meals
- Drink one glass of water with medication
- Drink when you feel thirsty
- Track your intake with apps
