hydrate and rehydrate, Plenty of fluids before you work,,during and after. " If your urine is not light yellow or almost clear you are behind on fluids." this is bass ackwards ----> (if the Urine is light yellow or Dark) You need MORE water ! Clear Urine indicates you have drank enough water for the time . at high temperatures and high humidity One must drink more water to keep the body from dehydration and the toxic levels in the Urine flushed out . any color in the during the hottest parts of the day or any other time is an indication of the need of water . Per the Military, and with 27 years trust me I drink a lot of water thorough the day when it is Hot .
Now Retired and still drink water all most all the time .
