MS3 Water Refilling Station

Our bodies are around 60% water, give or take.

It is commonly recommended to drink eight 8-ounce glasses of water per day (the 8×8 rule).

Although there is little science behind this specific rule, staying hydrated is important.

Here are 7 evidence-based health benefits of drinking plenty of water.

1. Water Helps to Maximize Physical Performance.
Bottom Line: Losing as little as 2% of your body’s water content can significantly impair physical performance.

2. Hydration Has a Major Effect on Energy Levels and Brain Function.
Bottom Line: Mild dehydration (fluid loss of 1-3%) can impair energy levels and mood, and lead to major reductions in memory and brain performance.

3. Drinking Water May Help to Prevent and Treat Headaches.
Bottom Line: Drinking water can sometimes help relieve headache symptoms, especially in people who are dehydrated.

4. Drinking More Water May Help Relieve Constipation.
Bottom Line: Drinking plenty of water can help prevent and relieve constipation, especially in people who generally do not drink enough water.

5. Drinking Water May Help Treat Kidney Stones.
Bottom Line: Increased water intake appears to decrease the risk of kidney stone formation. More research is needed in this area.

6. Water Helps Prevent Hangovers.
Bottom Line: Hangovers are partly caused by dehydration, and drinking water can help reduce some of the main symptoms of hangovers.

7. Drinking More Water Can Help With Weight Loss.
Drinking plenty of water can help you lose weight.

This is due to the fact that water can increase satiety and boost your metabolic rate.

In two studies, drinking half a liter (17 ounces) of water was shown to increase metabolism by 24-30% for up to 1.5 hours (26, 27).

This means that drinking 2 liters of water every day can increase your total energy expenditure by up to 96 calories per day.

The timing is important too, and drinking water half an hour before meals is the most effective. It can make you feel more full, so that you eat fewer calories (28, 29).

In one study, dieters who drank half a liter of water before meals lost 44% more weight, over a period of 12 weeks (30).

It is actually best to drink water cold, because then the body will use additional energy (calories) to heat the water to body temperature.
