The National Academies of Sciences recommends a baseline water intake calculated at approximately 0.5 to 0.7 ounces per pound of body weight. Physical exertion and warm weather rapidly deplete fluids through perspiration, demanding proactive replenishment to maintain peak cognitive and physical performance.
