@runnersworld From a physics standpoint, phase-change sleeves and the like are a bad idea. They feel cool at first as the wax melts, but once it’s liquid (just minutes later), the effect is gone. After that you’re stuck carrying extra weight and an insulating layer that blocks natural cooling.
@_notyourbuddy_@wholemars We’ve got them in all flavors down here 😂 but I was surprised it didn’t detect this type. They seem pretty standard and easy to spot to me.
The Omius technology relies on evaporative cooling and requires the cooling pieces to be wet to function properly.
As mentioned in the article, when the pieces were wetted, the headband improved thermal comfort in the first part of the study (even though they used only 6 ml of water, which is significantly less than the amount needed to fully wet the cooling elements).
In the second part of the study (the 5k time trial), they didn't wet the headband, which obviously affects how it's supposed to work. They even mentioned this limitation in the study. The research did find an improvement of 2.2% in performance, but it was not statistically significant, partly also because of the small sample size and the poor control of the participants' initial conditions. Quoting the study: "Rectal temperature was significantly lower with the Sham Headband compared to the Omius headband PRIOR to the start of the test."

As a physics engineer, I fully support scientific studies (we're currently working on one ourselves) just please try to conduct them fairly. We're happy to help!

You're not being quite fair there Alex.
1) The new study you mentioned used 400 ml of water, while the headband study only used 6 ml, significantly less than the amount needed to fully wet the cooling elements.
2) The new study doused the water during the time trial test, the headband study did not.
3) The new study was able to measure a 1% performance improvement because the sample size was 30% larger, and they did a great job controlling the initial conditions. The headband study measured a 2.2% performance increase, but it ended up not being statistically significant partly due to the small sample size and the poor control of the participants' initial conditions. Quoting the study: "Rectal temperature was significantly lower with the Sham headband compared to the Omius headband PRIOR to the start of the test".
¡Se lleva el oro! Mexicano inventó bandas de enfriamiento para evitar golpes de calor; las usaron varios medallistas en #Paris2024.

@tavocadena platica cómo nació Omius, el proyecto que dio origen a la banda enfriadora que la medallista de oro, Sifan Hassan utilizó en París.
