Answer:dehydration occurs when more fluid is lost or used from the body than is taken in. symptoms includes: Thirst,Dry or sticky mouth,Not peeing very much,Dark yellow pee,Dry cool skin ,Headache, Muscle cramps.
Explanation:You can lose more water than usual with excessive body activity like athletic and exercise.Exercise causes body fluid losses from moisture in exhaled air as well as from sweating.
Exercise produces heat. Prevention of overheating occurs by transfer of heat to the skin by vasodilation of the cutaneous circulation, and by the cooling effect of evaporation of sweat. Exercise causes body fluid losses from moisture in exhaled air as well as from sweating. Although sweat rates are highest under conditions of high-intensity exercise in heat and high humidity, total fluid losses can be appreciable in very prolonged events, whatever the conditions. Unless fluid losses are replaced by drinks, sweating causes progressive depletion of circulating blood volume, leading to hypohydration (commonly called dehydration).
To prevent dehydration drinking plain water causes bloating, suppresses thirst (and thus further drinking) and stimulates urine output (therefore is inefficiently retained) – a poor choice where high fluid intake is required. Sports drinks generally contain 10-25 mmol/litre sodium, as salt – well below the optimal concentration for stimulating fluid absorption, but the ideal concentration would taste like sea-water, and palatability is vital. This will help incorporate proper hydration into future training endeavors. Hope this helps.
