The negative effects of dehydration on physiological responses (e.g., increased cardiovascular and thermal strain), exercise performance (e.g., reduced endurance, strength and power), and health (e.g., greater risk of heat exhaustion and exertional heatstroke) have been widely documented in hundreds of publications since 1940. These detrimental effects are graduated in proportion to the amount of dehydration accrued during exercise lasting 2–3 h or longer in a hot environment (e.g., 1–4% body weight loss; 45–70% maximal aerobic power; > 33 °C). Because sweat loss and water intake are the primary factors in determining net exercise-induced dehydration, and because humans do not voluntarily replace all body weight loss via drinking (Hoffman et al. 2018), athletes/laborers/soldiers are justified in seeking supplementary approaches to practically and appropriately minimize resulting body water and weight loss.
