The Science of Hydration: How Water Impacts Your Wellness
Everything you need to know about proper hydration. How much water you really need and why it matters for your health.
Water makes up about 60% of your body. Every cell, tissue, and organ needs water to function properly.
Why Hydration Matters
Proper hydration:
- 💧 Regulates body temperature

Signs You're Dehydrated
Watch for these warning signs:

- Fatigue — even mild dehydration causes tiredness
- Headaches — often the first sign
- Dry mouth and skin

How Much Water Do You Actually Need?
Forget the "8 glasses a day" rule. Your needs depend on:
| Factor | Impact | |--------|--------| | Body weight | Larger bodies need more | | Activity level | Exercise increases needs | | Climate | Hot weather = more water | | Diet | Salty foods increase needs |
Simple formula: Drink half your body weight (lbs) in ounces of water daily.
Example: 160 lbs = 80 oz (about 2.4 liters)
