When should you turn off your fan in extreme heat? 🥵. Our work in @BNEJournal suggests they are safe up to 43°C in young adults, higher than the updated @WHO guidance . Open Access: @hrpcsg @NUSMedicine @cbe_berkeley @LakeheadRsrch @NSERC_CRSNG.

Feel free to reach out if you are interested in using HeatSuite. It is constantly expanding and there are many new features coming online.

However, a tool is only good if people can use it. So we set out to see what the individual compliance rate would be for a 28 day monitoring period, in some of the most heat-vulnerable people. Our system demonstrated moderate to near optimal compliance.

It layers this with real-time personalized environmental exposure data to give a comprehensive overview of an individuals heat-health response. Moreover, the researchers/clinicians have full data governance, which enables deployment in regions where sharing of data is difficult.

HeatSuite is a low cost, highly scalable, simple, and efficient all-in-one solution for researchers and clinicians interested in remotely monitoring various physiological, behavioural, and perceptual responses in more ecologically valid conditions.

🎊Latest publication in npj Digital Medicine, a part of the @NaturePortfolio . After years in the making - literally - its first publication is finally here. Meet, HeatSuite. Read about it here: or read the TL:DR in this thread 👇.

These findings extend our previous evidence published in Medicine & Science in Sports & Exercise, suggesting antihistamines from all generations may be safe for use prior to heat stress. This challenges many heat health guidelines globally.

Using a double-blind randomized crossover design, we show that neither diphenhydramine (Benadryl), loratadine (Claritin), or desloratadine (Aerius), alter sweating - or heart rate, skin blood flow, or blood pressure - during passive heating when taken as directed.

Now published in @AllergyEaaci . The latest output led by Douglas Newhouse (now MSc) continuing our investigation of whether antihistamines impair sweating during heat stress. Freely available here: @CROSH_CRSST @LakeheadUKIN @NUSMedicine @hrpcsg.
