The human body comprises around 60% water.

It’s commonly recommended that you drink eight 8 to 12 glasses of water daily

Although there’s little science behind this specific rule, staying hydrated is important.

Here are 7 evidence-based health benefits of drinking plenty of water

1. Skin Clarity and Health

Drinking enough water has a tremendously positive effect on skin clarity and health. Dehydration promotes the formation of wrinkles, and it can also lead to dry skin and certain rashes and skin disorders. Adequate water intake, though, helps keep the skin soft, hydrated, clear and lustrous.

The benefits of drinking water for skin also extend to your youthful appearance — the collagen that supports healthy, firm skin is about 60% water by weight, so enough water intake may help keep this protein plump and help prevent premature aging. Other factors like sun exposure and genetics, though, also play a role.

Serious levels of dehydration can cause what is called skin turgor or elasticity. One method of measuring dehydration is the pinch test. Pinch your skin over the back of your hand, hold it for a couple of seconds, and release. If the skin doesn’t become flat in five seconds, you’re dehydrated.

2. Kidney Function

Adequate hydration also helps maintain proper kidney function. Water is essential to help the kidneys preserve the body’s homeostasis by filtering fluids, regulating fluid levels and maintaining electrolyte balances in the body.

Flushing too little water through the kidneys can lead to problems like kidney stones. Why? Water helps dissolve minerals and nutrients and remove waste products. If there isn’t enough water available, minerals and nutrients build up in the kidneys and accrete as stones. When waste products accumulate in the kidneys, it forces these vital organs to work much harder than they would otherwise have to. These issues potentially lead to chronic kidney disease and kidney failure. But consuming the proper amount of water helps keep the kidneys healthy and functioning effectively.

Higher fluid intake increases the volume of urine passing through the kidneys. This dilutes the concentration of minerals, so they’re less likely to crystallize and form clumps

3. Weight Control

The benefits of drinking water for weight loss and healthy weight maintenance are also substantial. Juices and many sodas are high in calories and sugar. Extra calories quickly lead to added weight, and excessive sugar consumption can lead to cravings that wreak havoc on a thoughtfully planned diet. Water contains no calories and can help the body feel full and stave off cravings.Preloading” with water before meals can help prevent overeating by creating a sense of fullness.

4. Joint Health 

Adequate water consumption is essential for joint health. Water helps form necessary lubrication for the joints to prevent friction and pain as the body move-

Cartilage, found in joints and the disks of the spine, contains around 80 percent water. Long-term dehydration can reduce the joints’ shock-absorbing ability, leading to joint pain

5. Blood Pressure Regulation

Consumption of water helps regulate blood pressure. Dehydration can lead to a thinning of the blood, which, in extreme cases, can cause dangerous drops in blood pressure that could harm the internal organs. But drinking enough water helps maintain a healthy blood consistency and keep blood pressure numbers within the recommended ranges. Drinking water before giving blood can also increase blood pressure enough to keep donors from getting woozy — it reduces the incidence of fainting from lowered blood pressure by up to 20%. Blood is more than 90 percent water, and blood carries oxygen to different parts of the body.

6. Digestive Efficiency

Drinking enough water aids the digestive system. Water helps form the saliva we need to start breaking down food as we consume it. And water is essential for proper intestinal function as well. Without an adequate supply of water, the stomach experiences increased concentrations of acid, and the intestines cannot break down food or transport food waste through the body effectively. These issues can lead to symptoms of gastric distress, such as heartburn, constipation and stomach ulcers. But water dilutes stomach acid and helps bulk up food waste and move it through the body more easily. Some believe that drinking hot water is especially effective for activating the digestive system.

The theory is that hot water can also dissolve and dissipate the food you’ve eaten that your body might have had trouble digesting.

7. Brain Function

One of the most significant health benefits of water is its positive effect on brain function. Water helps provide the fluid necessary to cushion the brain and spinal cord and protect them from injury. And evidence suggests that dehydration can lead to the disruption of the hormones and neurotransmitters needed for proper brain function, particularly the functions involved in reasoning, focus and short-term memory. Adequate hydration, though, can promote healthy brain function and clear, measured thinking.

lack of water, can influence the brain. Even mild levels of dehydration can interfere with your mood and functioning, especially in young children and older loved ones, or on hotter days when there’s a greater risk of heat stroke. Dehydration can affect concentration
