Extreme heatwaves pose significant health risks for women, particularly as climate change drives more frequent and intense heat events. On July 9, 2026, experts highlighted that women's cardiovascular systems are more vulnerable during heatwaves, leading to greater health challenges compared to men.
Biological Vulnerabilities in Women During Heatwaves
Women's bodies respond differently to heat, primarily due to hormonal fluctuations and physiological differences. Dr. Nighat Arif, an NHS GP specializing in women's health, explains that women produce less sweat and start sweating at higher temperatures than men. This physiological trait makes it more difficult for women to regulate their body temperature during extreme heat.
Research indicates that women also typically have a higher core body temperature and a greater body fat percentage, which can act as insulation against heat, further complicating their ability to cool down. The natural hormonal fluctuations during the menstrual cycle, pregnancy, and menopause can exacerbate these challenges, making temperature regulation even more difficult.
Socioeconomic Factors Exacerbating Heat Stress
In addition to biological vulnerabilities, socioeconomic circumstances significantly affect women's health during heatwaves. Dr. Cat Pinho-Gomes, a public health consultant at UCL, notes that women often face challenges such as lower income and caregiving responsibilities, which can hinder their ability to care for themselves in extreme temperatures. These factors contribute to a heightened risk of heat-related health issues.
Older women are particularly at risk, as they tend to live longer than men and are more susceptible to heat-related complications. Age-related conditions, such as dementia, can impair their ability to recognize thirst or manage heat stress effectively, leading to increased vulnerability during heatwaves.
Menstrual and Menopausal Effects During Heatwaves
Women often experience heightened sensitivity to heat during their menstrual cycles. Dr. Arif explains that the rise in progesterone during the second half of the cycle can increase core body temperature, intensifying discomfort during hot weather. Symptoms such as fatigue and dizziness are not uncommon, as noted by women who reported feeling faint and exhausted during the recent heatwave.
For menopausal women, heatwaves can worsen symptoms like hot flushes and night sweats. Dr. Arif states that these symptoms, linked to decreasing estrogen levels, can become more severe during heat events. Women undergoing chemical or surgical menopause also report increased discomfort, emphasizing the need for targeted support during these challenging conditions.
- Women sweat less and start sweating at higher temperatures.
- Higher body fat percentage can insulate against heat.
- Hormonal fluctuations complicate temperature regulation.
- Socioeconomic factors limit self-care capabilities.
- Older women face increased risks due to health conditions.
