Adapting to a new environment (e.g., heat, cold, altitude) can take one to three weeks. Having a good aerobic fitness base will accelerate your acclimation to new environments. However, factors that can negatively affect acclimation include:
♦ Drinking alcohol.
♦ Cessation of physical activity.
♦ Electrolyte depletion.
♦ Inadequate energy intake.
General guidelines for nutrition and physical activity in altered climates are outlined and followed by brief descriptions of the effects that heat, cold, and altitude have on metabolism.
