Onion in your pocket vs 50°C heat? Minister's claim sparks debate

A viral heatwave "hack" meets hard science- and reveals why surviving extreme summer is no place for shortcuts.

In Short

• The remark echoed a long-held rural belief about summer survival
• Experts said onions may help only when eaten, not carried
• Doctors found no clinical evidence linking onions with heatstroke prevention

The crowd in Pichhore had gathered for a routine inauguration on Sunday, the kind that usually fades from memory by sunset. But this one didn’t. Not after Union minister of Communications Jyotiraditya Scindia reached into his vehicle, pulled out an onion, and held it up like a quiet talisman against the blazing sun.

“I may look young, but my soul is old,” he said, half in jest, half in conviction. Then came the advice that would ripple far beyond Shivpuri: carry an onion in your pocket, and the heat won’t harm you.

For a region simmering under a brutal heatwave, the idea landed somewhere between folklore and hope.

HEATWAVE MEETS BELIEF

Across large parts of India, the sun has turned unforgiving. Roads shimmer. The air feels heavy. Stepping outside between late morning and afternoon is less a chore and more a calculated risk. In that context, Scindia’s suggestion didn’t sound entirely out of place – it sounded familiar.

Because it was.

In many rural pockets, carrying an onion during peak summer is an old belief, passed down without footnotes or studies. It sits alongside other inherited wisdom: drink buttermilk, cover your head, avoid the angry hours of the sun. The onion, in this story, isn’t just a vegetable. It’s a shield.

And when a public figure echoes that belief – adds his own endorsement, even a personal anecdote about relying on “Chambal skin” instead of air conditioning – it gives the idea new life.

Curiosity followed. So did questions.

SCIENCE PUSHES BACK

Strip away the symbolism, and the onion does have some science behind it-but not the kind that fits in a pocket.

When eaten, onions contain compounds like allyl sulfides and quercetin. These can encourage mild perspiration, helping the body cool itself through evaporation. Their high water content adds a small hydration benefit. Ayurveda has long considered onions a “cooling” food-for consumption.

But that’s where the evidence stops.

There are no clinical trials showing that even eating onions significantly protects against heat stress, pointed out Dr Anoop Misra, a veteran internal medicine specialist, whose work also involves research in nutrition.

And more importantly, there is no scientific basis whatsoever for the idea that carrying one – untouched, unconsumed – can prevent heatstroke.

Clinician-researchers are blunt about it: the body doesn’t absorb protective compounds from an onion sitting in your pocket.

“Heatstroke is physiological, not symbolic. It doesn’t negotiate with tradition,” said a physician at AIIMS, Delhi who specialises in heat-related illnesses. He underlined that exposure to severe heat, when not coupled with scientifically proven measures, can be serious, even life-threatening.

"Over the last few years, these deaths are growing as both daytime and nighttime temperatures are rising during the summer months and those who worked outdoors – such as street vendors - who spend long hours in oppressive heat are particularly susceptible," he said.

What actually works isn’t mysterious, even if it’s less charming than a pocket remedy.

Hydration matters – consistently, not just when thirsty.

Foods with high water content help. Electrolyte balance keeps the system stable. And perhaps most crucially, avoiding direct sun exposure during peak hours – roughly 10 am to 4 pm – can make the difference between discomfort and danger.

The onion, it turns out, belongs on the plate, not in the pocket.

The moment in Shivpuri will likely linger – not because it solved anything, but because it tapped into something deeper: the human urge to find simple answers in extreme situations.

But when the temperature climbs past 45, even touching 50 degrees, survival isn’t about belief – but biology.
