Acclimation helps you remain active in a hot environment with less
risk of a heat-related illness. You can acclimate yourself to a hot environment

You can also start acclimating while in cooler environments by
wearing more clothing when exercising. This will raise the body temperature,
which helps the body start sweating.

temperature. Although this increases the amount you sweat, it decreases the
amount of salt you lose in sweat or urine.
