This produces\u003cbr\/\u003e a local decrease in forehead skin temperature.\u003c\/p\u003e \u003cp\u003eBecause the system is driven solely by water evaporation, the effect is sustained —not cold storage—\u003cbr\/\u003e as long as three conditions are met simultaneously: wet pieces, direct contact with the skin,\u003cbr\/\u003e and airflow over the pieces (generated by movement or, indoors, by a fan).\u003c\/p\u003e \u003ch3\u003eUsage Specifications\u003c\/h3\u003e \u003cul\u003e \u003cli\u003e\u003cstrong\u003eFormat:\u003c\/strong\u003e headband + 20 cooling pieces + carrying case\u003c\/li\u003e \u003cli\u003e\u003cstrong\u003ePiece material:\u003c\/strong\u003e high thermal-conductivity graphite with hydrophilic coating\u003c\/li\u003e \u003cli\u003e\u003cstrong\u003eRe-wetting:\u003c\/strong\u003e every 30–40 min during use, with water at any temperature\u003c\/li\u003e \u003cli\u003e\u003cstrong\u003ePre-cooling:\u003c\/strong\u003e no refrigeration or freezing required\u003c\/li\u003e \u003cli\u003e\u003cstrong\u003eCompatibility:\u003c\/strong\u003e pieces are removable and interchangeable between Omius headband, visor, and cap\u003c\/li\u003e \u003cli\u003e\u003cstrong\u003eTarget users:\u003c\/strong\u003e endurance athletes (running, trail, triathlon, cycling, open-water swimming) training and competing in heat or humidity\u003c\/li\u003e \u003c\/ul\u003e \u003ch3\u003eScientific Evidence\u003c\/h3\u003e \u003cp\u003eLocal head cooling acts on cutaneous thermoreception and, through it, on perceived exertion.\u003cbr\/\u003e Available evidence —including an independent study from Université de Sherbrooke published in\u003cbr\/\u003e \u003cem\u003eJournal of Thermal Biology\u003c\/em\u003e (2024)— shows that the technology reduces forehead temperature\u003cbr\/\u003e and improves perceived thermal comfort and perceived exertion in hot and humid conditions.\u003c\/p\u003e \u003cp\u003eThe same study found no reduction in core body temperature (rectal or mean skin) and no performance\u003cbr\/\u003e improvement in a 5 km time trial.
