7 Science-Based Health Benefits of Drinking Enough Water
The human body comprises around 60% water. Its commonly recommended that you drink eight 8-ounce (237ml) 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
This is particularly important during intense exercise or high heat.
2. Significantly affects energy levels and brain function
Studies show mild dehydration (fluid loss of 1-3%) cam impair energy levels, impair mood, and lead to major reductions in memory and brain performance.
3. May help prevent and treat headaches
Research has shown that a headache is one of the most common symptoms of dehydration.
4. May help relieve constipation
Mineral water may be particularly beneficial to help relieve this problem, especially in people who generally don’t drink enough water.
5. May help treat kidney stones
Higher fluid intake increases the volume of urine passing through the kidneys. This dilutes the concentration of minerals, so they’re less likely to crystallize and form clumps.
6. Helps prevent hangovers
Alcohol is a diuretic, so it makes you lose more water than you take in. This can lead to dehydration. Good ways to reduce hangovers are to drink a glass of water between drinks and have at least one big glass of water before going to bed.
7. Can aid weight loss
Some evidence suggests that increasing water intake can promote weight loss by slightly increasing your metabolism, which can increase the number of calories you burn on a daily basis.
