  • The nutritional value of water

    In terms of nutrition, tap water contains zero calories. This alone is a great reason to consume more.

    Unlike almost all other consumables, water is not a source of carbohydrates, proteins or fats. [1] Its only function is to hydrate you and you can drink a lot of it. without worrying about any weight gain.

    5 scientific benefits of water

    Water has so many benefits for your health that it would be impossible to list them all in this article. However, here are 5 scientifically and academically supported solid benefits that water has for your health and why you should always stay adequately hydrated.

    1. Drinking water keeps it at peak performance

    Your physical performance may suffer if you do not drink enough water. In fact, your physical performance can be seriously affected if you lose as little as 2% of water in your body. The result of this may be things like fatigue, loss of control of body temperature, less motivation and exercising will feel much more difficult from a mental and physical perspective.

    On the other hand, studies show that a good level of hydration not only prevents the above, but can even reduce the oxidative stress that accompanies high intensity activities. This makes sense when you think about the fact that water makes up 80% of the muscles. [2] So stay well hydrated to stay in peak physical condition.

    2. Water is good for brain function

    Your hydration level has a big impact on your brain function. Studies show that even a modest level of dehydration of 1-2% (reduced water in the body) can affect many brain functions. [3] This was highlighted in a study conducted with young women at the University of Connecticut. The research shows that women who had a fluid loss of 1.36% after exercise suffered an altered concentration, bad mood and many more headaches. [4]

    A similar study involving young men also shows that a fluid loss of 1.59% increases feelings of fatigue, anxiety and reduces memory of job.

    3. Drinking water can help prevent and treat headaches

    This follows from the previous point that shows how important water is to the functioning of the brain. Dehydration is often the main cause of migraines in many people. However, new studies show that drinking water can be an effective way to treat and even prevent headaches in the first place. [5]

    4. Water provides nutrients to your body

    Although pure water does not contain any nutrients, it can absorb some minerals and carry it to your body. [6] For example, bottled mineral water can sometimes contain healthy minerals that your body needs such as sodium, magnesium and calcium.

    Just be sure to read the label to know the exact mineral content of your bottled mineral water.

    5. Water helps your body regulate temperature

    Water is excellent for absorbing and transferring heat to your body. In fact, it is the main way in which the human body can regulate its temperature.

    Water has a relatively high heat capacity and means that the water in each cell of your body can function as a shield against sudden changes in temperature. [7] This is also the reason why professionals always recommend drinking lots of water in hot climates or environments.
