As temperatures rise across the globe, a disturbing trend is gaining attention: domestic violence against women tends to increase during hot weather and heatwaves.
Multiple studies from different regions show a clear connection between higher temperatures and a rise in intimate partner violence, highlighting an often-overlooked social impact of climate change.
Research indicates that even moderate increases in temperature can lead to heightened aggression and conflict within households, disproportionately affecting women.
Scientific evidence confirms alarming trend
A growing body of global research confirms that domestic abuse incidents rise during warmer days.
A large-scale study found that domestic violence increases when temperatures exceed 27°C, pointing to a direct link between heat and aggression.
Another analysis of nearly one million incidents revealed that “violence increased with warmer weather” and that the effect of heat was stronger on domestic violence than other types of crime.
Researchers have also found that for every 1°C rise in temperature, cases of physical violence against women can increase by over 4 percent in South Asia.
Heatwaves intensify risk of severe violence
The danger becomes even more severe during extreme heat events.
Studies from Spain showed that the risk of intimate partner femicide increases significantly following heatwaves, with incidents peaking just days after temperatures surge.
In some cases, abuse rates have been found to rise by up to 28 percent during prolonged heatwaves, underscoring the scale of the problem.
Similarly, research in New Orleans linked extended periods of extreme heat to spikes in emergency calls related to domestic violence.
Why heat triggers violence
Experts say the relationship between heat and violence is complex, involving both psychological and social factors.
Extreme temperatures can increase irritability, stress, and sleep disruption, all of which can escalate conflict within households.
Heat is also associated with increased alcohol consumption and reduced tolerance, further contributing to aggressive behavior.
Additionally, during very hot weather, people tend to stay indoors more often, increasing prolonged exposure between victims and abusers, which can heighten the risk of violence.
Climate change worsening the crisis
With global temperatures rising due to climate change, experts warn that domestic violence could become more frequent in the future.
Studies suggest that extreme heat plays a “dominant role” in increasing the risk of violence in intimate relationships, especially in low- and middle-income countries.
Regions like South Asia, including Pakistan, are particularly vulnerable due to rising temperatures and existing social inequalities.
A hidden public health emergency
Domestic violence is already one of the most widespread human rights violations globally, and the link with heat adds a new layer of urgency.
Experts argue that climate policies must consider social impacts such as gender-based violence, alongside environmental and economic concerns.
They also stress the need for stronger support systems, including helplines, shelters, and awareness campaigns, especially during extreme weather events.
Growing call for action
As awareness grows, policymakers and advocacy groups are urging governments to integrate gender-based violence prevention into climate response strategies.
This includes early warning systems, community support networks, and targeted interventions during heatwaves.
The emerging evidence makes one thing clear: rising temperatures are not just an environmental crisis but also a social one, with women often bearing the greatest burden.
