Our bodies consist mostly of water. Each cell, organ or tissue needs water to stay alive and function normally. To stay hydrated is to enable our cells to properly exchange nutritional substances, regulate body temperature, and maintain a healthy balance of electrolytes that affect functionality of our nerves and muscles etc.
Why is it so important to stay hydrated?
If our body is not properly hydrated it will begin to shut down. Drinking enough fluids enables us to remove toxic body waste, process and absorb vitamins and minerals from food, and have a healthy metabolism, heart rate and blood pressure.
Even the slightest variation in percentage of water creates amazing changes in our bodies. If you lose only 2% of body-water, you won’t be able to perform intense physical activity (sports, hiking, running etc.). After you dehydrate 3% or 4%, your bio-physiology is disbalanced enough to increase heart beats, blood pressure and body-temperature. A loss of more than 10% of fluids is considered medical emergency.
