From minor side-effects like heat syncope, cramps, fatigue to heat strokes, which could be sometimes fatal, experts flagged the health issues related to rising mercury levels as several parts of the country are experiencing oppressive temperatures. Experts also said that heat waves could lead to sunburn and fungal infections.

Dr Dileep Mavalankar, Director of Indian Institute of Public Health, Gandhinagar, said the side-effects of heat waves could be minor as well as major, which may sometimes result in deaths or even permanent neurological damage. With regards to minor side-effects, Mavalankar said extreme heat can cause dehydration, for especially those who venture outdoors. It can also lead to heat cramps, fatigue. Extreme heat can also lead to heat syncope (fainting or dizziness).
