Excessive Heat: Causes, Health Risks, and Staying Safe in Hottest Summers

India is heating up—faster than almost anywhere else on Earth. In April 2025, temperatures pushed 44°C across multiple states, with Malegaon in Nashik recording mercury levels above 43°C. This excessive heat is no longer just a seasonal inconvenience; it is a public health emergency.

What is excessive heat?

Excessive heat refers to temperatures significantly above the normal range for a region, sustained over several days. In India, a heatwave is declared when plains reach 40°C with a departure of 4.5°C or more from normal. However, the real danger lies in the combination of high heat and rising humidity, which prevents the body from cooling itself through sweat.

How Excessive Heat Harms the Body

When excessive heat overwhelms your internal regulation, it can lead to a cascade of dangerous conditions:
Heat Exhaustion: Characterized by heavy sweating, dizziness, and nausea. Move to a cool area immediately.
Heat Stroke:A life-threatening emergency where the body temperature exceeds 104°F. If someone stops sweating or becomes confused, call 112
Chronic Impact:Prolonged exposure to excessive heat places a cumulative burden on the heart and kidneys, exacerbating existing conditions like diabetes and cardiovascular disease.

Who is Most Vulnerable?

While excessive heat affects everyone, certain groups face higher risks:
- The Elderly:Their ability to regulate temperature declines with age.
- Children:They produce more heat relative to their body size.
- Outdoor Workers:Those in construction or farming face 3 times higher odds of adverse health outcomes.
- Pregnant Women:High temperatures are linked to risks like low birth weight and preterm deliveries.

10 Ways to Beat Excessive Heat

1. Hydrate Early:Drink 3–4 litters of water daily; don’t wait until you’re thirsty.
2. Avoid Peak Sun:Stay indoors between 11 AM and 4 PM.
3. Dress Light:Wear loose, light-coloured cotton fabrics.
4. Cool Your Space:Keep curtains closed during the day to block direct sunlight.
5. Never Leave Kids in Cars:A parked car in the sun can reach 70–80°C in minutes.
6. Check on Neighbours:Ensure the elderly and those living alone are staying cool.
7. Eat Water-Rich Foods:Choose cucumbers, watermelon, and curd over heavy, oily meals.
8. Active Cooling:Use cool showers or damp cloths on your neck and wrists.
9. Store Meds Safely:High heat can degrade medicines like insulin or inhalers.
10. Know the Signs:Recognize the difference between heat cramps and a medical emergency.
