Furthermore, while these factors have often been chosen or adapted to produce the best outcomes in sporting applications, they can be impractical for military contexts. Therefore, the use of a long-term HA protocol to generate these adaptations is ideal, although if notice before deployment is short re-acclimation would be more suitable (Fig. Water is best.

Although no performance test was conducted, this resulted in lower core temperature ( 0.3C), heart rate ( 12 beat/min) and psychological strain, and an increased sweat rate ( 40%) during hot-water immersion on day 14 when compared to day 1 [279].

In 2007, the Intergovernmental Panel on Climate Change (IPCC) concluded that "hot extremes" and "heat waves" are very likely (>90% probability of occurrence) to increase as our climate continues to change.Footnote 10This predicted temperature increase is particularly pronounced for night temperatures, resulting in reduced night-time relief from the heat.Footnote 11In addition, Environment Canada (Figure 1) forecasts that many cities in Canada can expect a substantial increase in the number of days with temperatures exceeding 30C/86F, levels that are dangerous to human health.Footnote 12Footnote 13These changing weather conditions are a growing concern for individuals and communities in Canada.

Planned acclimatisation was investigated first, allowing soldiers a period of time in a new climate to adapt to the environment [19,20,21, 23,24,25,26], while later developments in heat chambers allowed artificial heat exposure to induce such adaptations [27,28,29,30], a process known as heat acclimation (HA).
