The Cold Plunge Challenge WMD 2026

Diving in for answers on women’s health

I’m excited to take The Cold Plunge Challenge because women deserve answers. Menopause influences 70% of age-related diseases, yet less than 1% of preclinical aging studies worldwide consider menopause in their research. It's time to change that. 

I'm plunging to support Sinai Health, one of the only academic centres in the world to make women's health a strategic priority. Together, we can help advance the research that will improve care for women before, during and after menopause—and across every stage of life. 

Please support my Cold Plunge Challenge with a donation. Every gift helps accelerate the discoveries women have waited far too long for.
