Why Women Feel Hotter Than Men: Understanding the Causes

Women often experience more discomfort during hot weather due to a combination of physiological and hormonal factors. Experts note that heatwaves place significant stress on the cardiovascular system, impacting women more severely than men and potentially increasing their risk of heat-related mortality.

Two primary reasons for women feeling hotter are the natural fluctuations in hormone levels and the body's response to heat. Research indicates women sweat less and at higher temperatures than men, hindering rapid heat dissipation. Additionally, women typically have higher internal body temperatures and more body fat, which acts as an insulator. Hormonal shifts during menstrual cycles, perimenopause, menopause, pregnancy, and breastfeeding can disrupt the brain's temperature regulation. Socioeconomic factors, such as women bearing the primary caregiving responsibilities in lower-income households, can limit their ability to manage heat stress. Age also increases sensitivity to heat, and as women generally live longer, they face prolonged health risks.

During menstruation, hormonal changes can heighten heat sensitivity. Progesterone increases body temperature before the period, leading to discomfort, while lower estrogen levels during menstruation can strain the cardiovascular system. Pregnancy also increases heat stress due to metabolic changes and fluid needs, with hormonal fluctuations exacerbating the issue. Menopausal women commonly experience hot flashes and night sweats, which intensify during heatwaves. Heat exhaustion, characterized by excessive sweating, fatigue, and dizziness, can progress to heatstroke if not managed, posing a significant risk to women's health.
