Happy Sunday!
During the hot summers growing up, my mom would sequester the whole family into the one room in the house that had an A/C. We'd hang sheets in the doorways to keep the air trapped in and play video games all day. I remember the wall of stifling air that I'd face when I'd pull back the curtain to run to the bathroom, always surprised by how hot it could get in our hometown. Now, I appreciate her ingenuity of keeping us cool.
Today's daily newsletter looks at the relationship between extreme heat and COVID-19, a new and formidable opponent in our global fight against the devastating impact of this disease.

July was a particularly rough month for America’s battle with COVID-19. With over 150,000 reported deaths, most states are seeing either a second surge or sustained first surge since March. 42% of all known cases in the U.S. were reported in July alone, and as states grapple with the ended of increased unemployment, moratoriums on rent and utilities, and the difficult decision of back-to-school, another silent factor is driving the spread and severity of COVID-19: extreme heat (NYTimes).
It might not garner the same level of attention as other natural disasters, but extreme heat is one of the most deadly types of weather-related events in the US, killing an average of 702 people each year. The CDC reports that extreme heat kills more than hurricanes, floods, and tornadoes on average each year (excluding major natural disasters they cause). When people become overheated for extended periods of time, their bodies may lose the capacity to cool itself down. This leads to spikes in body temperature that can damage the brain and other organs (CNN).
Extreme heat is getting more extreme here on Earth. Since the Industrial Revolution nearly 200 years ago, the global average temperatures have risen by nearly 2 degrees Fahrenheit (UCSUSA). A new study on global warming indicates that, due to the reckless pace of human-caused carbon emissions, global temperatures could increase by 4.1 to 8.1 degrees Fahrenheit over the next five decades (Washington Post). And recent reports of unprecedented heat from Siberia to Antarctica (Washington Post), Britain (The Financial Times), and the Middle East (NYTimes) proves that the heat is here to stay.
This is a problem for everyone, but particularly communities of color, who are more likely to live in U.S. counties threatened by extreme heat (UCSUSA). The neighborhoods where they live are often concrete-heavy, dense urban areas with few pockets of greenery. These spaces, referred to as “heat islands” in a recent comprehensive study, can have temperatures as much as 22 degrees higher than their surroundings (Pew Trust). These spaces don’t just exacerbate heart, lung, and kidney disease – health conditions people in these communities are more likely to be afflicted with. They exacerbate the impact of air pollution, another critical topic we’ve analyzed in our COVID-19 newsletter series. And people of color have been corralled in these heat islands for generations because of historical practices of redlining, segregating non-white people into limited and inadequate spaces (Pew Trust). The elderly, already susceptible to the virus, are the most impacted by these disparities.
If Americans stay home, they might be able to beat the heat. A Citylab study from 2015 found that nearly 90 percent of American households have air conditioning of some sort (Bloomberg). These numbers drop slightly based on the age of the home itself; newer residential spaces are more likely to have central air, for example, and older buildings may have a window unit. And even for lower-income communities the number only drops to 75% of households with A/C (Bloomberg).
But lower-income communities, in particular, are struggling to make ends meet, and rising energy costs are a hefty addition to the budget. Estimates indicate that running an A/C all day can cost approximately $12/day, adding $370 to a monthly bill. I used the calculator to estimate my cooling costs for the year, including equipment, in a small space in Brooklyn, NY, and got a range of $3,600 - $5,600 (hvac.com). Millions of people are already behind on paying their power bills since COVID-19 started, so adding hundreds of dollars for lowering the temperature indoors might be impossible (NPR). And because most families are spending more time at home than they would have before COVID-19, they’re facing increased costs in power regardless if they’re running the A/C or not (NPR)
To counter this issue, many states implemented power shut-off moratoriums earlier this year – alongside eviction moratoriums and other initiatives to protect financially-strapped communities. But most of these power-shut off moratoriums were set to expire July 15 or August 1. Some states have extended, but 17 states – including Georgia, Florida, and Arizona – have no official moratorium in place at all, although some power service providers have created moratoriums of their own (NEADA). As extra unemployment benefits end, analysts fear we may be approaching a “tidal wave” of power shutoffs in the midst of this extreme heat (NPR).
So these communities would spend time elsewhere – gathering at the local library or mall, hanging with friends, or frequenting coffee shops or restaurants. In some places, these spaces are closed altogether. But most cities have tried to keep them open to offer respite from the heat. These spaces, often referred to as “cooling centers,” may be a risky place to visit. New reports indicate that airborne transmission “plays a major role” in spreading the virus. Infected droplets can take about 30 minutes to sink from the mouth of an adult of average height to the floor (NYTimes).
To counter airborne viruses, ventilation is key. But ventilation is tricky in common residential or commercial spaces focused on keeping precious cool air in. Simple A/C and HVAC units may accelerate the spread of the virus by constantly circulating the infected air around a room. Benjamin Cowling, the head of epidemiology and biostatistics at the University of Hong Kong School of Public Health, studied a case of infections at a restaurant in Guangzhou where an asymptomatic COVID-19 patient infected nine other people. The people infected were at other tables and never came into contact with the patient. But each sat in the direct line of the air conditioner, which was blowing air from one end of the restaurant to the other (The Atlantic).
Solving ventilation problems can be relatively easy – locations can upgraded filters in their HVAC systems, or use portable HEPA filters to catch airborne particles as they circulate (The Atlantic). The CDC has offered an additional list of precautions for “cooling centers” to protect others, including buying PPE for guest use, cleaning frequently, maintaining social distance, and raising awareness. And as temperatures lower across the country, it will be easier for locations to open windows to encourage fresh air. But closed and cool spaces can still be dangerous, and may themselves be impacted by the growing burdens of power costs.
Extreme heat isn’t just a public health issue. It’s a key part of the disparities that make racism a public health crisis. August tends to be a hot, if not hotter, month across the country so we can expect the burden of extreme heat and its intersection on COVID-19 to persist. We’ll see the same disparities come into play in the winter, when it’s warmth – not cooling – that’s costly and difficult to navigate with ventilation. We must rally for the people in our communities most impacted by the fluctuations in temperatures in the months ahead.
