MUMBAI, May 27 -- As the summer heat continues to bear down on the city, the worst affected are those compelled to work in the open - construction workers, gig workers, traffic police personnel and officers on census duty. Everyone who is directly exposed to the heat has said that this year's weather feels harsher and more exhausting than usual. Temperatures have hovered between 33 and 35 degrees Celsius and humidity at 65%, in Colaba, and 64% in Santacruz observatories on Tuesday, with the maximum being 35 degrees and minimum 28 degrees. The maximum temperature on Wednesday is expected to be 34, while the minimum 29, with light rain and thunder shower expected. Thereafter, the weather is expected to become drier, with partial cloudy skies. Meanwhile, those spending long hours outdoors said prolonged exposure to the sun leaves them drained, forcing frequent breaks with an increase in spends on water and cooling drinks. The heat brings along heat stress, particularly when humidity is high, as moisture in the air reduces sweat evaporation, the body's primary cooling mechanism. Adequate hydration, ventilation and avoiding prolonged exposure to heat are important precautions. "While healthy individuals can manage these conditions with normal precautions, vulnerable groups such as the elderly, children, outdoor workers and people with existing health conditions should remain cautious. Prolonged heat stress and dehydration can lead to health complications, including heat exhaustion and, in extreme cases, heatstroke," said a scientist from the India Meteorological Department, requesting anonymity. Healthcare personnel said the impact is already visible. "We are seeing more people reporting symptoms of acidity, headaches and general fatigue due to the heat. People should stay well hydrated and take basic precautions to manage the impact of rising temperatures," said Vikhroli-based Dr Yogesh Bhalerao. The NGO Jan Sahas, in collaboration with insurance companies Go Digit, K M Dastur Insurance and Reinsurance Brokers Pvt Ltd, and Good & Green (CSR initiative of Godrej Properties Limited), is also working to cushion informal workers from extreme weather conditions through a multi-peril parametric insurance product. "This year, over 1,308 workers in Mumbai enrolled for the insurance, which triggered a pay-out of Rs.2,500 per individual when heat stress thresholds were met," said Shailesh Acharya, director, Jan Sahas. All beneficiaries received the pay-out on Wednesday, to face the city's prolonged hot and humid conditions....
