Here is a list of 5 of the health benefits of water in the human diet.
1. Relieves Fatigue
It is also one of the most important benefits of water. If you often feel tired, there is a high chance that it could be due to inadequate consumption of water which makes the body function less efficiently. In fact, fatigue is one of the first signs of dehydration.
When there is less water in the body, there is a drop of blood volume which causes the heart to work harder to pump oxygenated blood out in the bloodstream, and other major organs also work less efficiently. Thus, drinking adequate water can help your body function better and reduce fatigue.
2. Improves Mood
Research indicates that mild dehydration (even one or two percent lower hydration level of hydration than optimal) can negatively affect your mood and ability to think. This is also a part of benefits of water.
A small study conducted on 25 women and published in the Journal of Nutrition found that being dehydrated can take a toll on your mood and cognitive function. The color of your urine is a good indicator of your level of hydration. The lighter the color the better the level of hydration and vice versa.
3. Treats Headaches and Migraines
If you have a headache or migraine, the first thing that you can do to get some relief is drink plenty of water. Headaches and migraines are often caused by dehydration.
In a study published in the European Journal of Neurology, researchers found that increasing water intake helped reduce the total number of hours and intensity of headaches in the study participants.
4. Helps in Digestion and Constipation
Improving digestion is also come in the benefits of water. Water also improves the functioning of the gastrointestinal tract. This helps in digestion and prevents constipation. Inadequate water in the body often results in constipation as the colon pulls water from the stools to maintain hydration, thereby making them harder and difficult to pass.
5. Aids Weight Loss
In a clinical trial, scientists found that drinking two eight-ounce glasses of water prior to meals can help suppress appetite and hence support your weight loss efforts. When you drink water, it fills your stomach and reduces the tendency to eat more. It is one of the most important benefits of water.
