Health Benefits of Drinking Enough Water Proven by Science

The human body consists of approximately 60% water.
The 88 rule states that you should drink eight 8-ounce (237-mL) glasses of water each day.
Keeping hydrated is essential, despite the fact that there is little evidence to support this particular rule.

Drinking a lot of water has seven health benefits that are supported by evidence.

1. Boosts physical performance to its fullest extent If you don’t drink enough water, your physical performance may suffer.

This is especially important when working out a lot or getting hot.Even if you only lose 2% of the water in your body, dehydration can be noticeable. However, athletes frequently sweat out as much as 6–10 percent of their water weight (1Trusted Source, 2Trusted Source).

Changes in body temperature control, decreased motivation, and increased fatigue may result from this. Additionally, it may make physical and mental exercise appear to be significantly more challenging.

This has been shown to be prevented by drinking enough water, and it may even lessen the oxidative stress caused by intense exercise. When you consider that approximately 80 percent of muscle is water, this is not surprising.

2. Significantly affects energy levels and brain function Your level of hydration has a significant impact on your brain.

Many aspects of brain function can be affected by even mild dehydration, like losing 1 to 3 percent of body weight, according to studies.In a study of young women, researchers discovered that exercise caused a 1.4% fluid loss, which affected mood and concentration. Additionally, it made headaches more frequent.

A similar study on young men was carried out by many members of the same research team. They discovered that a fluid loss of 1.6% was bad for working memory and made people feel more anxious and tired.

3. May aid in the prevention and treatment of headaches In some people, dehydration can cause headaches and migraines.

According to research, one of the most common signs of dehydration is a headache.Additionally, some studies have demonstrated that those who suffer from frequent headaches may benefit from drinking water to alleviate their symptoms.

The Migraine-Specific Quality of Life scale, a scoring system for migraine symptoms, showed that drinking an additional 50.7 ounces (1.5 liters) of water each day led to significant improvements on the scale, which was conducted on 102 men (16).Additionally, headache relief was reported by 47% of men who consumed more water, compared to 25% of men in the control group (16).
