Water is the main component of the human body. In fact, depending upon its size, the body is composed of 55% to 78% water.
There are a number of health benefits of adequate and regular water consumption. As an added plus, it has no calories!
Your daily water consumption plays a very important role in maintaining a healthy body. Experts recommend drinking 8 to 10 glasses of water every day.
Furthermore, the Institute of Medicine has determined the adequate intake of total beverage per day (AI) to be about 3 liters or 13 cups for men and 2.2 liters or 9 cups for women.
Water helps in keeping us well hydrated, which is essential for the proper functioning of almost every cell in our body.
Here are 10 biggest health benefits of drinking water.
1. Relieves Fatigue
If you feel tired and fatigued too often, there is a fair chance that this could be due to inadequate water intake, which makes the body function less efficiently.
Fatigue is one of the primary signs of dehydration.
When there isn’t enough water in the body, the blood volume drops, causing the heart to work harder to pump oxygenated blood out in the bloodstream. Moreover, other major organs also begin to work less efficiently.
Thus, drinking enough water can help your body function properly and reduce tiredness.
- The next time you feel a bit fatigued, try drinking a glass or two of water and see if you feel any better. If you do, it indicates that you need to increase the amount of water you drink daily.
2. Improves Mood
Research indicates that mild dehydration can negatively affect your mood and your ability to think. This can happen even if the hydration level is just 1 percent or 2 percent lower than optimal.
A study conducted on 25 women and published in the Journal of Nutrition states that dehydration can affect your mood and cognitive function. Your level of hydration can be known through the color of your urine. The lighter the color, the better the level of hydration, and vice versa.
3. Treats Headaches and Migraines
If you have a headache or a migraine, the first thing that you can do to get some relief is to 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 Treats Constipation
Lack of water in the body often leads to constipation. This happens because the colon pulls water from the stools to maintain hydration. As a result, the stools turn harder and become difficult to pass.
Drinking sufficient water boosts your metabolism and helps the body in breaking down the food properly. This helps the digestive system to work efficiently, thus promoting regular bowel movements. It is to be noted that warm water is especially beneficial for digestive health.
5. Aids Weight Loss
In a clinical trial, it was found that drinking two 8 oz glasses of water before meals can help in suppressing appetite and support weight loss efforts.
Plus, water can promote the breakdown and elimination of fat cells. Calorie-free water is also a great replacement for high-calorie drinks such as alcohol, sugary fizzy drinks, and sodas that often contribute to weight gain.
6. Flushes Out Toxins
Water is an excellent detoxifier as it helps flush out toxins from your body and get rid of waste, primarily through sweat and urine. It also promotes kidney function and reduces kidney stones by diluting the salts and minerals in the urine.
It is important to consume an adequate amount of water throughout the day. However, experts warn against drinking too much water. Although uncommon, it is still quite possible. Excessive water intake may reduce your kidneys’ ability to filter out waste. This is why it is recommended to limit your water intake to the amount your body requires for proper functioning.
As the amount of water required by the body tends to differ from one person to another, it is usually suggested to drink to your thirst. Also, include other fluids and foods with high water content in your diet.
7. Regulates the Body Temperature
An ample amount of water in the body also helps regulate the body temperature.
Water aids in maintaining an even body temperature, owing to its thermal properties and its ability to release heat from the body when sweat evaporates from the skin’s surface.
8. Promotes Healthy Skin
Water keeps the body well hydrated and improves the capillary blood flow, which promotes a healthy and young-looking skin. It helps to replenish skin tissues, moisturizes the skin, and increases its elasticity.
When the body gets enough water, your skin feels hydrated and looks moisturized, fresh, and healthy. Also, water helps prevent and treat soft lines, scars, acne, wrinkles, and other signs of aging.
9. Relieves Hangover
Drinking water is a simple yet effective way to get rid of a hangover.
Hangovers are not really a result of dehydration. However, it is known to add to symptoms such as dry mouth, fatigue, thirst, and headache. All you need to do in order to avoid dehydration is drink enough water. For example, you can have a glass of water (or any other nonalcoholic fluid) between alcoholic drinks.
It is recommended to have 16 oz to 20 oz of water at night before going to bed when you have had too much to drink.
10. Beats Bad Breath
Bad breath indicates that you may not be drinking enough water!
Water keeps your mouth moist and washes away food particles and bacteria. Moreover, it dilutes the smelly compounds created by oral bacteria.
Rinsing with water or drinking a glass of water has a significant effect on morning bad breath.
So, drink sufficient water and don’t forget to rinse your mouth, especially after having a meal or snack to control bad breath. This will also help remove bacteria and food debris stuck between the teeth and gum line.
You must exert necessary efforts to ensure adequate water intake.
However, it is important to make sure that the water you drink is clean and filtered. Increasing the consumption of other fluids as well as fruits and vegetables that are high in water content also helps.
