Other advice would be to start the day with a drink, as you would have gone several hours without fluid during sleep whilst losing fluid during the night through sweat and expiration. And what are the benefits? 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. 3.1.1.2 Cardiovascular system.
