Why in news?
A recent report from the US-based research group Climate Central reveals that climate change increases the heat exposure for pregnant women worldwide and leads to health risks.
- The report examined data from 247 countries and territories that focused on measuring increased heat exposure for pregnant women since 2020.
Key Findings of the Study
- A report reveals that climate change has significantly increased exposure to dangerous heat levels during pregnancy.
- Pregnancy heat-risk days – In 222 out of 247 countries climate change has at least doubled the average annual number of "pregnancy heat-risk days" over the past five years.
- Impact on developing countries – Developing countries with limited healthcare access showed the largest increases in heat exposure.
- Most affected regions include the Caribbean, Central and South America, Pacific islands, Southeast Asia, and sub-Saharan Africa.
Implications
- Public health risk – Pregnant women are increasingly vulnerable to heat-induced complications, posing a growing maternal and fetal health crisis, especially in under-resourced regions.
- Heat-related pregnancy complications are,
- Premature birth
- Stillbirth
- Birth defects
- Gestational diabetes
- Policy urgency – Beyond tackling climate change at a global level, there is a need for local adaptation strategies, such as:
- Urban greening
- Pollution control
- Creation of cooling zones
- Public advisories specifically targeting pregnant women
- Research gaps – There is a limited understanding of the physiological mechanisms behind heat-related pregnancy risks, underscoring the need for further scientific studies.
- Health communication – Heatwave warnings and health advisories must include pregnant women as a high-risk group, which is currently rarely done.
