Early Heatwave Grips Kerala, Summer Diseases on the Rise

As summer approaches, Kerala is grappling with an unusual early heatwave, with temperatures soaring to 38 degrees Celsius, exceeding the average for March. The heatwave, attributed to the El Niño phenomenon causing warming of the equatorial Pacific Ocean, has led to a sudden increase of three to four degrees Celsius in various regions. Kannur, in particular, has experienced the highest temperatures in the country for nine consecutive days, reaching 37.9 degrees Celsius.

The rising temperatures pose concerns, not just for water reservoirs but also for public health. The scorching weather has contributed to the surge in summer diseases, with reports of 1701 cases of chickenpox, 19,632 cases of diarrhoea, and instances of jaundice. The health department recommends avoiding outdoor work between 11 am and 3 pm to minimize heat-related health issues.

The El Niño-induced heatwave is expected to persist, potentially pushing temperatures above 40 degrees Celsius if the current trend continues. The looming water shortage, aggravated by diminishing reservoir and well levels, adds urgency to the situation. The advisory includes precautions such as reducing tea, coffee, and alcohol intake, avoiding direct sunlight, using sunscreen, and maintaining hydration.

Meteorologist Rajeevan Erikkulam suggests that the El Niño phenomenon remains active, indicating a likelihood of further temperature increases despite the possibility of rain in March. Dr. AV Jayakrishnan from the Indian Medical Association emphasizes the importance of staying vigilant in extremely hot climates, advocating for measures such as avoiding direct sunlight and staying hydrated to mitigate the spread of summer diseases.
