A heatwave has settled over parts of Bangladesh, making life miserable for many, especially outdoor workers. Recent reports show temperatures in Rajshahi soared to 40 degrees Celsius, leading to at least one heat-related death. This is just one example of the health risks connected to the rising temperatures.
Meteorologists note that this is the third heatwave of the year. It started recently and might last until Saturday. Although the official stance categorizes the heat as ‘mild to moderate,’ the high humidity—between 60 and 100 percent—makes it feel far worse. Senior meteorologist Muhammad Abul Kalam Mallik explains that temperatures over 36 degrees, combined with other conditions, qualify as a heatwave.
For many workers, conditions are dire. Anower Hossain, a rickshaw puller in Dhaka, reports feeling drained after just a few hours of work. He highlights that even at home, the heat offers no respite. His reduced working hours translate into lower income.
Health professionals warn that extreme heat can seriously harm the body. Dewan Mashrur Hossain, from the Climate Change and Health Promotion Unit, emphasizes that high temperatures disrupt bodily functions, leading to dehydration and even organ failure. Elderly individuals and children are particularly at risk.
In Rajshahi, Abdul Alam, a bamboo trader, tragically collapsed and died from suspected heat stroke. Doctors confirm he arrived lifeless at the local health facility, emphasizing the urgency of addressing heat-related health issues.
Residents are also grappling with issues like power outages that can last up to 14 hours daily. Iqbal Hossain, an engineer at a local grid station, explains that electricity supply isn’t meeting demand, worsening the situation for families without cooling options.
Climate experts warn that such heatwaves are becoming more frequent due to climate change. A 2025 World Bank report found that 2024 saw rising temperatures cost Bangladesh around $1.78 billion—about 0.4 percent of GDP—largely due to health and productivity losses. Since 1980, maximum temperatures have risen by 1.1 degrees Celsius, while the perceived temperature has increased by 4.5 degrees, leading to more heat stress.
Rising temperatures have been linked to various health issues, from respiratory problems to mental health challenges like anxiety. Vulnerable groups—particularly women, children, and the elderly—are affected the most.
In Dhaka, which ranks as one of the world’s most heat-stressed cities, the situation continues to worsen. In 2024, heat-related health issues resulted in the loss of an estimated 25 million workdays. A recent report found that nearly 60 million people in Bangladesh faced dangerous heat for over 30 days each summer.
Experts stress that this escalating heat crisis presents an urgent public health challenge that requires immediate action, especially for the most vulnerable populations. As climate change continues to intensify these conditions, proactive measures are crucial for safeguarding health and well-being.
