The ongoing heat waves across India pose significant health risks, particularly for workers in sectors like construction and manufacturing. Dr. Mayanka Lodha Seth, a senior onco-histopathologist at Redcliffe Labs, highlights that workers are vulnerable to heat-related illnesses, which often go unnoticed until severe. She identifies three stages of heat-related stress, starting with thermoregulatory stress leading to dehydration and potentially advancing to heat exhaustion and heat stroke if not addressed. To combat these risks, Dr. Seth recommends five essential tests: electrolyte and kidney function tests, blood sugar monitoring, complete blood count (CBC), liver function tests (LFT), and tests for vitamin D, B12, and iron levels. Regular health monitoring during peak summer can help detect early signs of dehydration and nutritional deficiencies, allowing for timely interventions. Dr. Seth emphasizes that awareness and proactive health measures, including hydration and structured rest, are crucial for ensuring worker safety in extreme heat conditions.
