The human body can adapt to extreme temperatures through physiological changes, but these adaptations require consistent exposure and active maintenance. Without regular heat exposure, such as during winter months, the body's heat tolerance mechanisms deteriorate and must be rebuilt. However, there are biological limits to how much adaptation is possible, meaning that beyond certain temperature thresholds, even well-adapted individuals cannot safely function.
Why it matters
This research has implications for public health strategies as climate change leads to more frequent and severe heatwaves. Understanding the limits of human adaptation can help inform safety guidelines for workers in hot environments and vulnerable populations during extreme weather events.
Understand the Science
No matter where you’re from, there are things you can do to cope better with extreme temperatures. But it takes work to stop our bodies’ adaptations from slipping backwards over winter, and there are limits to how far we can go
