Doctors have refuted online claims that consuming or carrying onions can protect against heatstroke, particularly as extreme heat affects South Asia. This popular folk remedy, amplified by social media and some public figures, is considered dangerous health misinformation by medical experts.
Experts caution that relying on onions may cause individuals to forgo proven methods of heat protection.

Preventable measures against heatstroke include staying indoors during peak heat hours, maintaining cool homes, and wearing light clothing. The WHO advises regular water intake and seeking immediate medical attention for severe heat illness symptoms.
