Heatwave: Why Women Suffer More
24 Jun
Summary
- Women may struggle more in heat due to biological differences.
- Hormonal changes during the menstrual cycle increase body temperature.
- Post-menopausal women experience less efficient cooling mechanisms.
As temperatures are predicted to reach 40C, experts highlight that women may experience heatwaves more intensely than men. This vulnerability is attributed to several biological factors. Women generally sweat less efficiently, and hormonal shifts during the menstrual cycle can elevate core body temperature by up to 0.7C.
Furthermore, the process of vasodilation, where blood vessels widen to release heat, is less effective in women. This is due to smaller heart chambers and blood vessels, a disparity that can worsen after menopause when estrogen levels drop. Older people, children, and individuals with existing health conditions are also at increased risk.
Health advice emphasizes staying out of the sun during peak hours, typically 11 am to 3 pm. It is recommended to undertake physical activities during cooler morning or evening periods. Maintaining adequate fluid intake, applying sunscreen, and wearing hats are vital precautions for all during hot weather.
