The body controls its water level through the 'Renin angiotensin aldosterone system'. Furthermore, when core body temperature increases the body responds by increasing skin blood flow to help control the temperature rise. If we drink too much and become hypohydrated (overhydrated), our kidneys increase filtration rates to deal with the increased blood pressure, subsequently, aldosterone levels decrease, resulting in more water being extracted from the blood and deposited through urination.
