Category: Adaptation

The human body is remarkably adaptable, a fact particularly evident in its response to environmental temperature changes. But how long does cold tolerance last once you've adapted to chilly climates? The duration of this physiological conditioning depends on a variety of factors, including the consistency of exposure and individual characteristics.

Genetics play a role in how we perceive cold, with a variant of the *ACTN3* gene influencing some individuals' natural tolerance. However, personal perception and physical adaptation mean that you can be more tolerant to cold through consistent, deliberate exposure, building your body's resilience over time.

An estimated 1.5 billion people worldwide possess a genetic variant that makes them more resilient to cold, an evolutionary advantage from ancient migration. For some, this helps answer the question, "**Why do I tolerate cold better than others?**," but it is only one piece of the puzzle.

Genetics and lifestyle play a significant role in how our bodies react to low temperatures. It is possible to influence your body's sensitivity to cold, with both evolutionary traits and modern practices offering insights into how can people be more resistant to cold.
