The disproportionate impact of extreme heat on women is a critical public health concern, increasingly highlighted by experts worldwide. Research indicates that women often face heightened vulnerability to the physiological and social stresses imposed by rising temperatures, necessitating more focused strategies for protection and awareness.
Physiologically, several factors contribute to this disparity. Hormonal fluctuations throughout a woman’s life, particularly during menstrual cycles, pregnancy, and menopause, can influence thermoregulation and hydration levels, potentially making women more susceptible to heat-related illnesses like heatstroke and dehydration. Women’s generally smaller body mass can also mean a quicker onset of heat stress compared to men, though individual variations exist. Pre-existing health conditions that are more prevalent in women, such as certain autoimmune disorders, can also be exacerbated by high temperatures.
Beyond biological differences, socio-economic and cultural factors play a significant role. Women often bear a greater burden of caregiving responsibilities, looking after children, the elderly, or sick family members, which can limit their ability to seek refuge from heat or access cooling resources. Traditional clothing norms in some cultures may also restrict air circulation and heat dissipation. Furthermore, women’s occupational roles, particularly in sectors like agriculture or informal labor, may expose them to prolonged periods of outdoor heat without adequate protective gear or access to water and rest breaks. Economic disparities can also restrict access to air conditioning, proper ventilation, or even adequate hydration, leaving women in lower-income households particularly exposed.
The risks are compounded during pregnancy, where the physiological demands on the body are already elevated. High ambient temperatures can increase the risk of adverse maternal and fetal outcomes, including preterm birth, low birth weight, and stillbirth, making pregnant women a particularly vulnerable demographic during heatwaves. Recognizing these multifaceted challenges, health authorities and climate adaptation specialists are advocating for gender-sensitive approaches to heatwave preparedness and response. This includes developing targeted public health campaigns, ensuring equitable access to cooling centers, and integrating women’s specific needs into broader climate resilience plans to mitigate the health burden of a warming planet.
