As the saying goes, always adopt the "tit for tat" way of living. Get yourself hotter from inside when you can't bear the heat outside.
Consume golgappe, masala chat with a lot of mirch when the heat starts getting unbearable around 10.30 AM. Rub some chilli powder on your body and have 4-5 red chillies with your lunch. Finish your dinner with 250 ml mirchi soup which should ideally constitute of 100 gm green mirch, 110 gm red mirch and 40 ml water.
