Does holding an onion while stepping out really prevent heatstroke? Here’s what you must know

Many of us must have heard our parents or grandparents ask us to hold an onion or put one in the pocket while stepping out, for prevention from heatstroke during the summer season. However, now as grownups we wonder whether it really works.

Does holding an onion while stepping out prevent heatstroke?

The idea of carrying an onion in your pocket to prevent heatstroke is a popular folk remedy in some cultures. However, according to experts there is limited scientific evidence to support its effectiveness in preventing heatstroke as heatstroke occurs when the body's temperature regulation system fails, leading to dangerously high body temperatures. So, the efficacy of carrying an onion in one's pocket seems mostly anecdotal.

Other benefits of onion during summers

Onions contain compounds such as quercetin, which have antioxidant properties and may potentially have some health benefits. Some proponents of the onion remedy suggest that the onion's cooling properties could help regulate body temperature and prevent heat-related illnesses.

5 prevention measures you must take while stepping out in the sun

Use sunscreen: Apply a broad-spectrum sunscreen with an SPF of at least 30 to all exposed skin, including your face, neck, ears, and hands. Reapply sunscreen every two hours or more frequently if swimming or sweating.

Wear protective clothing: Opt for lightweight, cotton clothing that covers as much skin as possible. Cover your head with caps, wide-brimmed hats, and wear sunglasses with UV protection to provide additional protection against harmful UV rays.

Limit going outdoors: Limit your time in direct sunlight, especially during peak hours between 10 a.m. and 4 p.m. Plan your workouts early mornings or evenings.

Stay hydrated: Drink plenty of water to prevent dehydration. Avoid excessive consumption of alcohol and caffeine, as they can lead to dehydration.

Protect your eyes: Wear sunglasses that block 100% of UVA and UVB rays to protect your eyes from sun damage and reduce the risk of cataracts and other eye conditions.
