How Extreme Heat is Reshaping Lives

Fast Summary

• The human body uses mechanisms like sweating and blood vessel dilation to adapt to heat, but rising global temperatures are straining these systems.
• Hyperthermia leads to protein malfunctions, changes in DNA structures, and accelerated biological aging.
• Heat shock proteins help protect cells by refolding damaged proteins and aiding autophagy,but their effectiveness diminishes under extreme conditions.
• Older adults exposed to heatwaves exhibit signs of cellular stress, reduced immunity, increased apoptosis (cell death), and inflammation.
• Long-term exposure to high temperatures induces epigenetic changes linked to faster aging; individuals living in hotter regions experience more than a year of added biological aging annually compared to cooler areas.
• Researchers are exploring ways to increase heat tolerance through exercise or potential drug interventions; however, extreme heat remains a major health risk globally.

Indian Opinion Analysis

India’s vulnerability to rising temperatures poses serious challenges given its long summers and increasing frequency of severe heatwaves across states like Rajasthan and Odisha. Urban areas with dense populations may face heightened risks due not only to environmental factors but also systemic deficiencies such as inadequate healthcare infrastructure for managing hyperthermia-induced illnesses.

Epigenetic studies revealing connections between prolonged exposure and accelerated cellular aging add an extra layer of urgency for policymakers-heat-related health repercussions could strain an already overstretched public healthcare system while also affecting labor-intensive sectors where physical endurance is paramount.Proactive measures integrating technology-driven cooling innovations along with awareness campaigns might reduce the impact on sensitive groups such as older adults or low-income workers heavily reliant on outdoor tasks during peak temperature months.
