Health Benefits of Drinking Enough Water: Our bodies are roughly 60% water, give or take. The 8-ounce rule suggests drinking eight 8-ounce glasses of water per day.
Although there is little science to back up this particular rule, staying hydrated is critical.
Here are seven scientifically proven health benefits of drinking plenty of water.
1 Water Aids in Physical Performance
Physical performance can suffer if we do not stay hydrated. This is especially important during strenuous exercise or in hot weather.
Dehydration can have an impact even if you only lose 2% of your body’s water content. However, it is not uncommon for athletes to lose up to 6-10% of their body weight through sweat.
This can result in altered body temperature control, decreased motivation, increased fatigue, and making exercise feel significantly more difficult, both physically and mentally.
2 Hydration Has a Significant Impact on Energy Levels and Brain Function
The state of your hydration has a significant impact on your brain. Mild dehydration (1-3 percent of body weight) has been shown in studies to impair many aspects of brain function.
A fluid loss of 1.36 percent after exercise impaired both mood and concentration and increased the frequency of headaches in a study of young women.
Another study, this time in young men, found that 1.59 percent fluid loss was detrimental to working memory and increased feelings of anxiety and fatigue
3 Water may aid in the prevention and treatment of headaches
Dehydration can cause headaches and migraines in some people (14, 15). Water has been shown in several studies to relieve headaches in dehydrated people.
4 Drinking More Water May Aid in Constipation Relief
Constipation is a common condition marked by infrequent bowel movements and difficulty passing stool. Increasing fluid intake is frequently advised as part of the treatment protocol, and there is some evidence to support this.
5 Drinking Water May Aid in the Treatment of Kidney Stones
Urinary stones are clumps of mineral crystal that form in the urinary system and cause pain. Kidney stones, which form in the kidneys, are the most common type.
There is limited evidence that water consumption can help prevent recurrence of kidney stones in people who have previously had them.
6 Water Aids in the Prevention of Hangovers
A hangover is a set of unpleasant symptoms that occur after consuming alcohol. Because alcohol is a diuretic, it causes you to lose more water than you take in. This can result in dehydration (24, 25).
Dehydration is not the primary cause of hangovers, but it can cause symptoms such as thirst, fatigue, headache, and dry mouth.
Drinking a glass of water between drinks and at least one large glass of water before going to bed can help reduce hangovers.
7 Drinking More Water Can Help You Lose Weight
Drinking plenty of water can assist you in losing weight. This is because water can increase satiety and boost your metabolic rate.
Drinking half a litre (17 ounces) of water was shown in two studies to increase metabolism by 24-30% for up to 1.5 hours.
This means that drinking 2 litres of water per day can increase your total daily energy expenditure by up to 96 calories.
