Heat acclimation for exercise and hot weather
Last reviewed 3 August 2026. How we write this.
Repeated heat exposure can expand plasma volume and improve heat tolerance, particularly when paired with exercise preparation.
Adaptations can include earlier sweating and reduced strain at a given workload. They are specific to heat preparation, not proof of broad detoxification.
Preparation must remain progressive
Heat illness can develop quickly. Acclimation is not permission to ignore temperature, symptoms or hydration.
