Explore how India’s record-breaking temperatures are not just an environmental crisis but also a looming psychological emergency. Learn about the alarming mental health implications of extreme heat waves sweeping the nation.
Urban heat island effect in Indian city
India is facing an unprecedented climate emergency as temperatures soar to record-breaking highs month after month. While the physical impacts of climate change—water scarcity, crop failures, and infrastructure damage—often dominate headlines, a more insidious crisis is brewing beneath the surface. The extreme heat isn’t just threatening our bodies; it’s affecting our minds. This concerning trend demands immediate attention as scientific evidence suggests that rising temperatures could be pushing humanity toward widespread psychological distress, with particularly severe implications for India’s vulnerable populations who work outdoors in the blistering heat.
Record-Breaking Heat: India’s New Normal
India has experienced unprecedented temperature increases in 2024, with each month breaking historical records in succession. According to the India Meteorological Department (IMD), January 2024 was the hottest January on record, only to be surpassed by February, and so on through May, which shattered all previous high-temperature records for the month. This isn’t just a seasonal anomaly—the past eleven months have all ranked among the hottest in recorded history for their respective time periods, indicating a clear pattern of accelerating climate change across the subcontinent.
The Central Research Institute for Dryland Agriculture reports that since 1901, India has experienced a significant temperature increase of 0.7°C, with heat waves becoming more frequent and intense, particularly in the last decade. In major cities like Delhi, temperatures frequently exceed 45°C during summer months, making outdoor activities nearly impossible during peak hours.
While the physical consequences of extreme heat are well-documented, emerging research suggests that climate change is having profound psychological effects. A 2023 study published in The Lancet Planetary Health found that for every 1°C increase in average temperature above regional norms, mental health-related hospital admissions in India increased by approximately 7.9%.
The human brain has evolved to function optimally within a specific temperature range. When ambient temperatures exceed these limits, our neural circuits—which rely on precise electrochemical processes—begin to malfunction. Just as fever affects cognition during illness, rising external temperatures disrupt normal brain function on a population level.
Research from the National Institute of Mental Health and Neurosciences (NIMHANS) in Bangalore indicates that extreme heat exposure impairs cognitive function, decision-making abilities, and emotional regulation. These effects are particularly pronounced in urban heat islands, where concrete structures amplify temperature increases, and in rural areas where agricultural workers have no choice but to work through the hottest parts of the day.
Vulnerable Populations: The Unequal Burden of Climate Change
The psychological impacts of climate change are not distributed equally. India’s large population of outdoor workers—street vendors, construction laborers, agricultural workers, and traffic police—bear the brunt of this crisis. According to the International Labour Organization, India could lose 5.8% of its total working hours by 2030 due to heat stress, equivalent to 34 million full-time jobs.
The inequity extends beyond economic factors. A report by the Centre for Science and Environment reveals that while the wealthiest 0.01% of the global population contributes disproportionately to carbon emissions, it is the common citizen who faces both the blame and the consequences. Corporate greenwashing strategies often shift responsibility to individuals—encouraging recycling, reduced electricity usage, and public transportation—while the largest industrial emitters continue business as usual.
In Bihar, a recent report documented a six-fold increase in dog bite incidents within a single month—not due to rabies but because the animals themselves are suffering psychological effects from extreme heat. Similar behavioral changes have been observed in typically non-aggressive animals like cows and goats, highlighting how rising temperatures affect all living beings.
As India confronts the reality of climate change, we must expand our focus beyond physical infrastructure and adaptation strategies to include the mental health crisis that looms on the horizon. The evidence suggests that without immediate and decisive action to address climate change, we may be heading toward an era of mass psychological distress. This calls for comprehensive climate policies that address both emission reductions and psychological support systems, particularly for vulnerable populations. The time to act is now—before the heat changes not just our environment, but our very minds.
