Heat Stress: The Third Deathly Hallow after Environmental Degradation and COVID-19

Our body maintains a core temperature of 37.5°C, whether we’re in a snowstorm or a heat wave but as the temperature increases, our body works harder to keep its core temperature down. The result of which is sweating. To keep the body cool, the sweat evaporates, which vehemently increases the heat loss from the skin. This puts strain on the body and can lead to dizziness, fainting, confusion, nausea, muscle cramps or worse organ failure.

Old age and some long term conditions such as heart diseases, diabetes type 1 and 2 can leave people more vulnerable to heat stress. Children and babies who are less mobile will also be at risk and people suffering from dementia will be left unaware and helpless to do anything about it. The violent pace of global warming will make the conditions too hot for humans to work in. Especially, the daily wagers such as farmers, mine workers, construction workers, rickshaw pullers and cab drivers. Currently the worst sufferers are the doctors and the health workers who have to wear protective equipment to avoid contacting infection. They can’t turn on the air conditioners as it will increase the probability of infliction to COVID-19.

In India, heat waves have killed about 6,167 people over a period of eight years ending in 2018. Moreover, India does not recognize heat wave as a disaster under its Disaster Management Law, thereby cutting it off from the government’s Disaster Response Fund. It is predicted that the annual average temperature will increase up to 1.5°-2°C by 2030. It had already risen by 2°C in the past 200 years till 2006.

At least 1.2 billion people in India will be living in areas as hot as the Sahara in the coming 50 years if the greenhouse gas emissions keep rising. The impact of heat stress is not limited to sectors where employees are directly exposed to sunlight. Small industries, such as cloth-weaving units, which cannot afford air-conditioning, are also vulnerable to production losses due to a rise in temperatures, found a 2018 study prepared by the Energy Policy Institute at the University of Chicago, a think-tank. For every 1°C rise in temperature beyond 27°C on a hot day in India, productivity of workers drops by as much as 4 per cent, the study stated.
