Understanding Heat Waves in India: Causes, Impacts & Prevention

A heat wave occurs when temperatures soar abnormally high for several days, posing serious health risks and disrupting daily life. In India, heat waves have become more intense and frequent – especially during late spring and early summer.

🌡️ Current Heat Wave Conditions in India (June 2025)

• New Delhi is currently under a red alert, with daytime highs reaching 46.3 °C, and “feels like” temperatures soaring to 52 °C. A yellow alert remains through June 13.
• Parts of Haryana (Sirsa, Rohtak, Hisar) are experiencing a severe heat wave, with temperatures between 46–48 °C .
• The broader Northwest India region has faced extreme heat since early April, with records hitting 47.3 °C in Sri Ganganagar.

Ashamedly, the India Meteorological Department (IMD) warns of continued oppressive conditions till mid-June, before relief arrives with rain and thunderstorms .

🧭 What Causes Heat Waves?

Heat waves in India are driven by multiple factors:

• Climate change: Rising greenhouse gas levels leading to hotter, longer summers.
• Deforestation and urbanization: Heat islands form as built-up areas absorb more heat.
• Weather patterns: Lack of pre-monsoon rain and high-pressure systems intensify heat wave conditions.

⚠️ Health & Environmental Impacts

• Extreme heat can cause heatstroke, dehydration, fatigue, and other heat-related illnesses. Vulnerable groups like the elderly, children, outdoor workers, and those with chronic conditions are at higher risk.
• Power outages, rising air pollution, and reduced crop yields are common during prolonged heat waves .
• Heat worsens physical and mental health, increasing stress, depression, and anxiety .

✅ Tips to Stay Safe During Heat Waves

1. Stay indoors during peak hours (11 am–3 pm).
2. Keep yourself hydrated; drink water frequently.
3. Wear light-colored, loose clothing and use sunscreen.
4. Avoid strenuous exercise in direct sun.
5. Cool the body using wet cloths or cold showers.
6. Consume fluid-rich foods like watermelon and cucumber.
7. Watch for heat-related symptoms: dizziness, nausea, excessive sweating.
