Pune Nights Stay Hot, Doctors Warn Heatstroke Risk Rising Even After Sunset

Experts say warm nights, humidity and lack of cooling recovery are increasing heat stress in Pune as summer intensifies.

Pune is facing a new heat concern this summer — not just scorching daytime temperatures, but unusually warm nights that are preventing the body from cooling down. Public health experts and doctors have warned that rising night temperatures can sharply increase the risk of heat exhaustion and heatstroke, especially for the elderly, children and people with existing illnesses.

While daytime temperatures in the city have remained around 39°C to 41°C, the bigger concern is that nights are no longer offering relief.

Night Temperatures Staying High

Recent readings showed daytime highs touching 39.9°C in Shivajinagar and 41.1°C in Lohegaon. Minimum temperatures also remained elevated, with Lohegaon recording 27.5°C, Chinchwad 26.9°C, and Shivajinagar and NDA both at 23.4°C.

Humidity levels also climbed overnight, making conditions more uncomfortable and reducing the body’s ability to cool naturally through sweating.

Why Warm Nights Are Dangerous

Doctors say the body normally recovers at night after daytime heat exposure. But when nights remain hot and humid, that recovery process gets disrupted.

This sustained thermal stress can build over several hours and may trigger heat-related illness later, even if a person was active earlier in the day.

Experts say heatstroke risk is not based only on temperature. Poor ventilation, trapped indoor heat, humidity and warm sleeping conditions can raise the body’s “felt temperature” significantly.

Early Symptoms Often Ignored

Doctors say many people dismiss early warning signs such as:

• Excessive thirst
• Tiredness
• Headache
• Dizziness
• Nausea
• Heavy sweating or weakness

If ignored, these symptoms can progress into heat exhaustion or heatstroke.

Who Is Most at Risk

The following groups need extra caution:

• Senior citizens
• Children
• Outdoor workers
• People with heart disease or diabetes
• Residents in poorly ventilated homes
• People without access to cooling

What You Can Do

Health experts recommend simple precautions:

• Drink water regularly through the day
• Use ORS if sweating heavily
• Keep rooms ventilated
• Use fans to push hot air out through windows
• Wear loose cotton clothes
• Use cool cloths or baths before sleep
• Avoid heavy activity during peak afternoon heat

Emergency Signs

Seek urgent medical help if someone develops confusion, fainting, very high body temperature, seizures, or stops sweating despite heat exposure.
