The human body comprises around 60% water. It’s commonly recommended that you drink eight 8-ounce (237-mL) glasses of water per day (the 8×8 rule).
Although there’s little science behind this specific rule, staying hydrated is important.
Here are 7 evidence-based health benefits of drinking plenty of water.
- Helps maximize physical performance
If you don’t stay hydrated, your physical performance can suffer.
This is particularly important during intense exercise or high heat.
Dehydration can have a noticeable effect if you lose as little as 2% of your body’s water content. However, it isn’t uncommon for athletes to lose as much as 6–10% of their water weight via sweat.
Bottomline, losing as little as 2% of your body’s water content can significantly impair your physical performance.
- Significantly affects energy levels and brain function
Your brain is strongly influenced by your hydration status.
