Acclimatization is defined as what?

• A. A temporary reduction in sweating
• B. A series of physiological adjustments that occur when exposed to hot climate
• C. Permanent genetic changes
• D. No physiological change

Answer: (B)

Acclimatization to heat involves a series of physiological adjustments that occur with repeated exposure to hot conditions. Over days to weeks, the body shifts several systems to better handle heat: plasma volume increases, helping maintain blood flow and keeping heart rate lower during heat stress; the sweating response becomes earlier and more robust, with sweat becoming more dilute to improve cooling efficiency while reducing electrolyte loss; and the body’s cooling and circulatory systems work more effectively to stabilize core temperature during activity. These changes improve tolerance and performance in hot environments and are reversible if heat exposure ends. This isn’t simply a temporary reduction in sweating, nor is it permanent genetic change, nor no physiological change at all.
