People most at risk are those over the age of 65, people with disabilities or pre-existing medical conditions and those working outdoors for long hours in non-cooled environments. Other factors that can increase risk include; limited access to green spaces, living in cities with high population density, living on a top floor and being homeless. Nowhere is immune to extreme heat but populations in the Europe and Eastern Mediterranean regions have been the most vulnerable of all the WHO regions, the 2020 Lancet report found.<\/p>\n
People with chronic or severe illness are likely to be at particular risk, including the following conditions:<\/p>\n
- \n
- Respiratory disease<\/li>\n
- Cardiovascular and cerebrovascular conditions<\/li>\n
- Diabetes and obesity<\/li>\n
- Severe mental illness<\/li>\n
- Parkinson’s disease and difficulties with mobility<\/li>\n
- Renal insufficiency<\/li>\n
- Peripheral vascular conditions<\/li>\n
- Alzheimer’s or related diseases<\/li>\n<\/ul>\n

\nOther impacts of heatwaves<\/h3>\n
The impacts of heatwaves extend beyond people\u2019s health; experts estimate that by 2030, lost productivity from heat stress at work, particularly in developing countries, will cost $4.2 trillion USD per year.<\/p>\n
\u201cAcross the globe, a potential 302 billion work hours were lost in 2019, which is 103 billion hours more than were lost in 2000. Thirteen countries represented 80.7 per cent of the 302,4 billion global work hours lost in 2019,\u201d The Lancet 2020 report found.<\/p>\n
The 2003 heatwave was estimated to have cost \u00a341 million in health-related costs and productivity losses in the UK alone. In the US, a 2014 study by economists Tatyana Deryugina and Solomon Hsiang looked at annual income data and daily weather data from 1969 to 2011 and found that years with more days above 59 F (15 C) are associated with significantly lower income per person: average per-day income declines by 1.5 per cent for each 1.8 F (1 C) increase in daily average temperature beyond 15 C (59 F).<\/p>\n
Several studies have also found links between extremely hot days and the worsening of people\u2019s mental health conditions. A study in Toronto associated the increased rates of emergency visits for mental health conditions to temperatures rising above 28 C (82 F).<\/p>\n
\nYet another equality issue<\/h3>\n
Like many public health issues, heatwaves do not impact everyone equally \u2013 they affect people of colour and lower socioeconomic status more than anybody else.<\/p>\n
\u201cThe people contributing to it least are suffering the most. There’s a link between hot communities and trees. Low-income communities don’t have trees whereas suburbs do. Trees help keep the temperature down and, more importantly, they absorb pollution,\u201d says Ms Baughman McLeod.<\/p>\n
\u201cBy contrast, people of lower economic status and of colour are more likely to be living next to industrial complexes that are emitting pollution. Most of the time in those areas there are no trees that can absorb pollution and heat is a key component of that.\u201d<\/p>\n
This was confirmed by a 2018 paper in the US that found people living in less vegetated areas had a five per cent higher risk of death compared to those living in more vegetated areas. Scientists at the University of California in 2017 mapped racial divides in the US by proximity to trees. Results were clear: black people were 52 per cent more likely than white people to live in areas of unnatural \u201cheat risk-related land cover,\u201d while Asian people were 32 per cent more likely and Hispanics 21 per cent.<\/p>\n
\nHeatwaves and climate change: a sign of what is to come<\/h3>\n
There are fingerprints of climate change all over the recent heatwaves. An overwhelming amount of scientific evidence suggests that climate change is already making heatwaves and extremely hot days more frequent and severe. The evidence also suggests that if immediate actions to reduce emissions are not taken, extreme weather events will become the norm. A 2019 report by the World Weather Attribution (WWA) found that the 2019 heatwave in western Europe \u201cwould have been extremely unlikely without climate change\u201d.<\/p>\n
More recently in 2020, Siberia hit a record-breaking temperature of 38 degrees celsius. Again, WWA found \u201cwith high confidence\u201d that the January to June 2020 prolonged heat \u201cwas made at least 600 times more likely as a result of human-induced climate change.\u201d<\/p>\n
\nWe must raise awareness<\/h3>\n
When Ms Baughman McLeod, along with international partners, decided to establish the Extreme Heat Resilience Alliance in summer 2020, their first priority was clear: raising awareness among decision-makers. \u201cWe found that heat was the place where there was not enough attention. I think it’s ironic that in 60 or 70 years of climate discussions, and we call it global warming, we’re not talking about heat. It’s killing more people than any other impact of climate change,\u201d she says.<\/p>\n
A report published in 2021 by the WHO concluded that public awareness of the health risk is relatively high in places that are regularly affected by hot spells. However, it also found that \u201cthe risk perception of heat among healthcare providers may be significantly lower than it should be, given the objective risks faced by their patients.\u201d<\/p>\n
Worryingly, the report also revealed poor levels of awareness of heat warnings among health professionals, including nurses in care homes, as well as a lack of knowledge of existing heat\u2013health plans among hospital front-line staff.<\/p>\n
Heatwaves are a silent killer, how can you solve a problem people don’t know about? In a landscape of crises, if something is not burning, people are not going to address it.<\/p>\n

How should we go about raising awareness and saving lives? The Extreme Heat Resilience Alliance believes that naming heatwaves can make a difference. Although Ms Baughman McLeod admits that this may not be as straightforward as naming hurricanes, she believes this can help save lives.<\/p>\n
\u201cWe’re trying to build a framework that can be adapted at a local met service and the existing heat health warning systems,\u201d she told Integrated Care Journal. \u201cWe’re piloting heatwave naming and we’ve put a science team together to help inform it. We’re also building a \u2018how to name heatwaves policy\u2019 toolkit for countries that we will take to the COP26 in Glasgow,\u201d she adds.<\/p>\n
