Why Some People Carry Onions in Their Pockets During Indian Summers: A Blend of Tradition, Belief, and Natural Heat Protection  

An age-old tradition meets modern science in the battle against heat

As temperatures soar across the country during peak summer, most people turn to water bottles, hats, and umbrellas for relief. However, in many parts of India, there’s a lesser-known tradition that continues to pique curiosity: carrying onions in pockets. Though it might sound unusual, this practice is deeply rooted in cultural beliefs and folk remedies passed down through generations.

Cultural Beliefs Behind the Practice

In Indian households, particularly in rural areas, it’s long been believed that keeping an onion in your pocket can help prevent heatstroke and protect against the adverse effects of extreme heat. While there is no conclusive scientific evidence to validate this claim, the tradition remains popular, especially among older generations.

The belief is that onions have a natural ability to repel heat and shield the body from sudden temperature changes. These customs have helped onions become more than just a kitchen staple—they’re also seen as protective talismans during the summer months.

Scientific Insights: Cooling and Medicinal Properties

From a scientific perspective, onions do possess several qualities that support the body’s response to heat. Rich in sulfur compounds and antioxidants such as quercetin, onions stimulate perspiration—an essential mechanism for natural cooling. As sweat evaporates, it helps regulate body temperature.

According to studies referenced by the National Institutes of Health (NIH), onions contain antioxidants that help reduce oxidative stress caused by heat-induced free radicals. These compounds may also offer anti-inflammatory benefits that can relieve common summer issues like allergies and respiratory discomfort.

Some traditional beliefs suggest that the volatile oils in onions absorb body heat, offering relief even when the onion is not consumed. This is believed to contribute to the comforting effect many people experience when carrying an onion in their pocket.

Fact or Folklore?

Although modern science hasn’t confirmed the effectiveness of carrying onions for heat protection, incorporating onions into the diet does offer real health advantages during the summer. Eating raw onions, for instance, helps maintain electrolyte balance and hydration due to their high water content.

A study published in the Journal of Chemical and Pharmaceutical Research also highlights that onions may reduce the risk of heart attacks, further underlining their overall health benefits.

A Blend of Tradition and Wellness

Whether viewed through the lens of cultural belief or nutritional science, onions remain a valuable ally in the Indian summer. While carrying one in your pocket may not be a medically approved solution, the symbolism and potential benefits of onions make them a respected part of seasonal well-being.

So the next time you step out into the blazing sun, don’t be surprised if someone reaches into their pocket and pulls out an onion—it’s not just tradition, it’s a reminder of how deeply culture and health are intertwined.
