Science Reveals the Importance of Drinking Enough Water for Health

There are about 60% types of water in the human body. In general, we recommend drinking eight 8-ounce (237 ml) glasses of water per day. There is little science behind this particular rule, but staying hydrated is important. Here are some science-based health benefits of drinking plenty of water. 

Helps Maximise Physical Performance:

Lack of hydration can reduce physical performance. 

This is especially important during vigorous exercise and high temperatures. 

Dehydration can have serious effects even if the amount of water in the body reduces to 2%. However, it is not uncommon for athletes to lose 6-10% water pounds through sweat (1 reliable source, 2% reliable sources). 

This can lead to changes in thermoregulation, decreased motivation, and increased fatigue. Exercising may feel more challenging both physically and mentally. 

Optimal hydration has been shown to prevent this and may also reduce oxidative stress that occurs during high-intensity exercise. This is not surprising since the water content in muscles is approximately 80%. 

If you exercise intensely and sweat easily, staying hydrated will help you perform at your best.

Significantly affects energy levels and brain function:

The brain is significantly affected by the state of hydration. 

Research shows that mild dehydration, such as a loss of 1 to 3% pounds in body weight, can disrupt many aspects of brain function. 

In a study of young women, researchers found that a 1.4% drop in water intake after exercise worsened both mood and concentration. The frequency of headaches also increased. 

May help prevent and treat headaches:

Studies show that headaches are one of the most common symptoms of dehydration.

Additionally, some studies have shown that drinking water may help reduce headaches in people who experience frequent headaches. 

A study of 102 men found that drinking an additional 50.7 ounces of water per day significantly improved migraine-specific quality of life, a scoring system for migraine Symptoms.

Plus, 47% of men who drank more water reported improvement in their headaches, while only 25 men in the control group reported this effect. 

Can help in providing relief from constipation:

Constipation is a common problem characterised by difficulty in passing and passing stools. 

Increasing fluid intake is often recommended as part of treatment protocols, and there is some evidence to support this. 

Low fluid intake appears to be a risk factor for constipation in both the young and the elderly. 

Increasing hydration may help reduce constipation. 

Mineral water is considered a particularly beneficial drink for people suffering from constipation. 

Studies have shown that mineral water rich in magnesium and sodium improves bowel movement frequency and bowel movements in people suffering from constipation.

May help treat kidney stones:

Urinary stones are painful masses of mineral crystals that form within the urinary tract. The most common form is nephrolithiasis, which occurs in the kidneys. There is limited evidence that fluid intake helps prevent recurrence in people who have previously had kidney stones.  

Increased water intake increases the amount of urine that passes through the kidneys. This dilutes the concentration of minerals and makes them less likely to form crystals or clumps. 

Water may also help prevent early stone formation, but research is needed to confirm this. 

Helps prevent hangovers: 

A hangover refers to the unpleasant symptoms experienced after drinking alcohol. 

Alcohol is a diuretic, so you lose more water than you drink. This can cause dehydration. 

Although dehydration is not the main cause of hangovers, it can cause symptoms such as thirst, fatigue, headaches, and dry mouth.  

A good way to reduce a hangover is to drink a glass of water between drinks and at least one glass of water before bed.
