Speaker A describes severe hot flashes affecting 40% of the global population and introduces MyCelsius, a cooling bracelet that lowers wrist temperature by 15°C in 20 seconds. The device targets the wrist's neural connection to the brain's thermostat to stop hot-flash episodes without cooling the whole room.

Chapters

I used to suffer a lot from hot flashes due to stress and anxiety. 10 years ago, I would be liquefying here. But very early in our journey, we were connected to a support group for women going through menopause. And quite frankly, we were heartbroken by some of the stories we heard. Hot flashes have a huge impact on women's health, wellbeing, but also professional lives. And ultimately, at least 40% of the world's population will at some point in their life struggle with hot flashes. So I'm proud to introduce you the MyCelsius cooling bracelet that I'm wearing. Wait, it's that small? Here, can we try it? Yeah, of course. So basically, it's fitted with an electric, electrocooling system And it cools your wrist down by 15 degrees in about 20 seconds. The science behind it is that it leverages the high thermal sensitivity of your wrist and it connects with your hypothalamus, the brain thermostat, very efficiently. Hot flashes, especially during menopause because of all the hormonal changes, are an overreaction.
Okay, I gotta stop you there because I gotta tell the audience, my hand is freezing right now. It feels like I've had an ice cube on there for like a week.
