Most of the human body is made up of water. Therefore, all organs need water to function properly. Thus, you must be clear that hydration is essential for your brain.
We all have physiological mechanisms to eliminate excess water, if applicable, and thus maintain the body’s water balance. For this reason, there is no known maximum recommended intake for water.
This is not to say that there are no consequences to taking it too much; however, the recommended amount per person may vary depending on their weight, age, health status and level of physical activity, among others.
Dehydration and physical activity
During intense exercise, the loss of body water can even lead to:
- Severe disturbance of thermoregulation
- Increased breathing rate during exercise
- Tingling and numbness of extremities
- Collapse, especially if the physical exercise is carried out in extreme heat conditions
All the organs of the human body need water, hydration is essential for your brain as well. For this reason, as detailed in a study published in 2011 in the journal Nutrition Reviews , even mild levels of dehydration can produce alterations in mood and cognitive functioning.
