Hotwired

In **Hotwired**, **Bill Gifford** blends narrative science writing with real-world experiments to show how deliberate heat exposure can sharpen performance and support long-term health. It’s an absorbing mix of physiology, personal reportage and practical curiosity—ideal for readers who like their wellness books grounded in evidence, not hype.

Gifford follows the latest research on how humans evolved to function in hot conditions, then tests those ideas in Finnish saunas, modern heat labs and an punishing 100-mile bike ride in the Texas sun. Along the way, he looks at what sauna culture gets right, how heat and cold training may influence mood and resilience, and why communal bathing is making a modern comeback.

Perfect for fans of **health and longevity** reading, **sports science**, **sauna therapy**, and anyone interested in climate adaptation and the body’s built-in stress responses.

Add it to your basket if you’re ready to rethink heat as a tool you can learn to use.
