Understanding how thermoregulation differs between these areas and those experiencing the greatest increases in humid heat is critical for future heat warnings and adaptation planning.

Looking into the future, there is a need to evaluate upper limits in a wider range of populations, as thermal step protocols have been employed primarily in laboratories from temperate areas.

Thermal step protocols are an effective and efficient method for estimating upper limits for thermoregulation. This is great news, as they are widely used and being increasingly incorporated into large scale #climate #modelling.

We exposed young adults for 9 hours to conditions just above or below the core temperature inflection point and found that thermal step protocols work extremely well.

However, despite being around for over 50 years, thermal step protocols have never been validated.

There are increasing concerns that #heatwaves of the future will be so hot and humid that they exceed the limits of human heat tolerance. Recent laboratory research using “thermal-step protocols” has argued that these limits are likely lower than once thought.

Our latest daylong heat exposure trial – Validating new limits for human thermoregulation – is out today in @PNAS. @robertdmeade @emtetzlaff @katiewagar1. Check it out below:.

Our findings suggest that there is a need for ecologically-minded physiological research, as the current evidence on the cardiovascular burden of heat may not be as complete as previously thought.

We found that water-perfused suits (the most commonly used modality to induce passive heat stress) led to exacerbated cardiac responses compared to resting exposures in climate-controlled chambers.

We evaluated data from over 400 laboratory-based heat exposure studies that involved more than 6,800 participant exposures published between 1961 and 2024.

Based on responses from 1000+ #olderadults in #Canada, we found that various factors influenced #knowledge, perceived #heatvulnerability, responsiveness to heat alerts, and perception of #communitypreparedness. These findings help inform public #heatpreparedness initiatives🥵🇨🇦.

With increasing #temperature #extremes and a rising tide of #toxic #druguse and #overdoses, our findings illustrate that there is a need for further research to understand better the combined impacts when toxic drug use, overdose-related deaths, and #extremeheat coincide.

The reported impact of toxic #druguse on #thermoregulation and behavioural adaptation, the demand on the #healthsystem, #barriers and #stigma influencing access to heat mitigation services were explored.
