Phase IFoundation

Background

Overview

UPSC frequently examines the impacts of climate change, disaster management strategies, public health challenges, and the role of governance in protecting citizens from environmental hazards. This concept integrates environmental science, public health, and policy responses.

Heatwaves are periods of abnormally high temperatures, often accompanied by high humidity, which can have severe impacts on human health, leading to heatstroke, dehydration, and exacerbation of pre-existing conditions. Effective public health management during heatwaves involves a multi-faceted approach to mitigate risks and protect vulnerable populations.

Facts & tables

Key facts

Health Risks

Heatwaves increase risks of dehydration, heatstroke, and impair the body's ability to regulate temperature.

Vulnerable Populations

Elderly, children, and individuals with chronic illnesses are particularly susceptible to heat-related illnesses.

Alcohol's Role

Alcohol consumption exacerbates heat-related risks by increasing urine production (dehydration) and dilating blood vessels (impaired thermoregulation).

Government Interventions

Measures include early warning systems, opening cooling centers, restricting high-risk activities (e.g., alcohol bans), and urban planning adjustments (e.g., 24/7 park access).

Post-2003More interventionist: cooling centers, checking on vulnerable, activity restrictions (e.g., alcohol ban, parks open 24/7)

Quick revision

  • Heatwaves: periods of extreme high temperatures, increasing in frequency/intensity due to climate change.
  • Health risks: dehydration, heatstroke, impaired thermoregulation, exacerbated chronic conditions.
  • Vulnerable groups: elderly, children, outdoor workers, chronically ill.
  • Mitigation strategies: early warning, cooling centers, activity restrictions (e.g., alcohol ban), urban green spaces.
  • Case study: France's post-2003 interventionist approach to heatwave management.
