A cooling bracelet created by a Bristol startup has earned a place on TIME magazine’s annual list of the best inventions of 2026, becoming one of only two UK entries in the Health & Wellness category. The device, developed by MyCelsius, provides relief from hot flushes without medication or hormonal treatments.
The MyCelsius bracelet delivers fast cooling through a proprietary system that targets the wrist. With a single button press, users can reduce skin temperature by up to 10°C within 10 seconds or 20°C over three minutes, according to the company. This approach avoids gels or pills, making it suitable for symptoms related to perimenopause, menopause, stress, or hormonal imbalances.
Maxime Kryvian, the startup’s co-founder and CEO, described the TIME recognition as significant. “To receive this recognition from TIME just one year after launching is an incredible milestone for our team,” he said. “But what matters most are the messages we receive from customers telling us the difference our bracelet is making to their everyday lives. That’s what drives us to keep innovating.”

The bracelet emerged from a gap in available solutions for hot flushes, which Kryvian and co-founder Aonghus O’Donovan, a former Dyson engineer, identified during their research. O’Donovan stressed the engineering rigor behind the design, noting that every aspect was refined based on direct input from women experiencing these symptoms. O’Donovan, who is also the chief technical officer of the startup, added: “There’s a lot of engineering packed into something you hardly notice you’re wearing, and every part of it was shaped by the women we worked closely with throughout its development. Having TIME recognise our invention means an enormous amount to our team, and I hope it shows what’s possible when we apply serious engineering to women’s health.”
The startup’s progress builds on earlier research partnerships, including work with Menochat, a Bristol-based menopause support network. The bracelet’s distinction lies in its portability and immediate results, setting it apart from existing cooling methods that often rely on external packs or gels.
