Climate can drastically change how much water you need. On hot days that require you to be outside, you should drink more water to counteract the fluids you lose when you sweat. This not only keeps your body hydrated, it can prevent heat-related illness. Just as important (but often overlooked) is consuming enough fluids in cold & wet conditions. The human body works much more efficiently (including heating and cooling) when properly hydrated. Inadequate water intake affects the brain's function first, which can become very dangerous (especially in extreme conditions). Canyan State Water provides a water station aboard MCAS just SW of the Dos Rios Inn, one at Cannon Air Defense Complex and one at 16th Street Housing.
