Does keeping an onion in your pocket prevent heatstroke? The truth behind this viral summer remedy

New Delhi: As temperatures rise during peak summer in North India-often reaching 45-50°C-the risk of heatstroke also increases significantly. In such conditions, people often turn to traditional home remedies that have been passed down through generations. One such belief has recently gone viral after a public statement by Union Minister Jyotiraditya Scindia, suggesting that keeping an onion in your pocket may help protect against extreme heat.

But does this practice really work?

Can an Onion in Your Pocket Prevent Heatstroke?

Medical science clearly states that there is no evidence to support the idea that carrying an onion in your pocket can prevent heatstroke. Heatstroke (commonly called loo) occurs when the body overheats due to prolonged exposure to high temperatures, direct sunlight, and dehydration. In such cases, the body loses its ability to cool itself down effectively.

Simply keeping an onion in your pocket has no impact on body temperature or heat regulation. While this belief is widely followed in some rural areas, it is not recognized as a scientifically valid method of protection against heatstroke.

Are Onions Beneficial in Summer?

Onions do have nutritional value. They contain antioxidants and sulfur compounds that may support overall health. Eating raw onions in summer is sometimes believed to have a mild cooling effect and may help stimulate sweating, which can assist the body in regulating temperature.

However, it is important to understand that eating onions alone cannot prevent heatstroke. They may be part of a healthy diet, but they are not a protective treatment against extreme heat.

Where Did This Belief Come From?

This tradition likely originated in rural communities where access to modern healthcare was limited. People relied on natural and practical observations to deal with seasonal illnesses. Over time, onions became associated with cooling properties, and the idea developed that keeping them close to the body could absorb heat. This belief continued to spread through generations, even without scientific backing.

Proven Ways to Prevent Heatstroke

Instead of relying on unverified remedies, it is important to follow medically recommended precautions:

• Stay well hydrated by drinking plenty of water throughout the day
• Use ORS, lemon water, or other fluids to maintain electrolyte balance
• Wear light-colored, loose, and cotton clothing
• Cover your head with a cap, scarf, or umbrella when stepping out
• Avoid direct sun exposure between 12 PM and 4 PM
• Eat seasonal fruits and vegetables to keep the body cool

Final Verdict

While onions are healthy food items, there is no scientific proof that keeping them in your pocket prevents heatstroke. The best protection against extreme heat is proper hydration, smart clothing choices, and avoiding prolonged exposure to the sun.
