Why Hydration Matters

Water makes up about 60% of your body weight. Every system in your body depends on it — from regulating temperature to flushing waste from your kidneys. Even mild dehydration — as little as 1-2% of body weight — can impair physical performance and cognitive function.

Tips for Staying Hydrated

Start your day with a full glass of water. Keep a water bottle visible. Eat water-rich foods like cucumbers, watermelon, and oranges. Drink a glass before each meal. Check your urine — pale yellow means well hydrated.
