Why women are more affected by hot weather than men

• Women have a higher core body temperature set point and delayed heat dissipation response compared to men, making them physiologically more vulnerable to heat stress and heat-related illness
• Sex hormones, particularly estrogen and progesterone fluctuations across the menstrual cycle and during menopause, impair thermoregulation and increase heat sensitivity in women
• Clinicians should consider sex-specific heat illness risk when counselling female patients, particularly those of reproductive age or in perimenopause, and lower thresholds for heat-related complications

Why are women’s bodies impacted by heat differently to men’s?
