Did you know that 50-65% of the human body is made up of water? Our blood is made up of almost 85% water! Water is vital to many major bodily functions, such as digestion of food, transporting waste, and controlling body temperature.
When it’s hot, we sweat more because the evaporation of the moisture helps cool us down. This ability to adapt to our environment is a key to health and the nervous system is responsible for controlling and coordinating this. Fortunately, our brain tells us to drink more water when we are thirsty… but that may mean we are already experiencing the early phases of dehydration if we wait until we are thirsty.
We need to replace approximately 2-3 liters of water daily since it is lost through sweating, breathing, and urination. (Individuals should urinate at least 4 times/ day.) The intake needed can vary with the individual depending on exercise, humidity, and temperature.
Don’t wait until you are thirsty to drink water today! Your body will thank you later.
