Raw onion works as a natural cooling food during extreme heat. It contains high water content and compounds like quercetin and sulfur that help regulate body temperature and protect against dehydration. Eating raw onion also supports electrolyte balance, which reduces the risk of dizziness, fatigue, and heat stroke during hot weather.
The right way to eat it is to consume sliced raw onion with meals, especially lunch, when heat exposure is highest. You can add it to salads with lemon and a pinch of salt, mix it in curd, or eat it with roti and vegetables. Combining onion with lemon and salt helps replenish minerals lost through sweat and improves cooling effect.
Avoid eating too much at once, as it may cause acidity in some people. One small onion per day is enough. Drinking enough water along with it improves its cooling benefits and helps the body stay protected from heat stroke.
