Heat stress and women’s health over the reproductive life course

Bringing together researchers from multiple disciplines to find out the effects of rising heat stress on women’s health.

The challenge

Mean temperatures are projected to increase and heat waves are expected to become more frequent and severe. Climate change is expected to affect men and women differently due to biological, socioeconomic and cultural factors. In particular, heat stress uniquely affects women because they have a compromised ability to thermoregulate during pregnancy and around menopause. This could reduce their ability to respond or adapt physiologically to a warming climate.

Little research has been done to look at heat stress and women’s reproductive health and none has focused on menopausal health. Given that about half of the population go through at least one of these life stages, more research is needed to inform the response of UK and global health systems to take into account gendered issues like pregnancy and menopause when preparing for climate change.

What we're doing

We are bringing together researchers from multiple disciplines to discuss how we can study the effects of rising heat stress on women’s health. We are holding a two-day workshop in Bristol, to which we will invite key researchers in climate science and women’s health.

The aims are to:

  1. Introduce and discuss the challenge;
  2. Generate a list of research questions and themes;
  3. Identify and discuss potential sources of data and methods to address these questions;
  4. Identify project(s) to take forward for major grant submissions, and who will lead on each.

Following the workshop, we will work with attendees to ensure progress on grant applications is made.

How it helps

By building capacity to conduct interdisciplinary research around the effects of heat stress on women’s health, our project will help identify ways of mitigating and managing health risks, thereby helping to achieve better health and quality of life on our warming planet.

We focus on effects of heat stress on pregnancy complications and menopausal health, so our project is relevant to a large proportion of the global population, with potentially far-reaching consequences. At both of these life stages, women can experience symptoms like hot flashes and night sweats, which can cause sleep disturbances, fatigue, cardiovascular events, reduced quality of life and mood disorders. In addition, during pregnancy, heat can exert further physiological strain and alter blood flow to the placenta, and high ambient temperatures have been associated with risk of hypertensive disorders of pregnancy and placental abruption, as well as preterm births, stillbirths, and fetal health outcomes.
