Narrative Information
(General)
EPA (Environmental Protection Agency) on Heat-Related Deaths (11-21-2023):
“When people are exposed to extreme heat, they can suffer from potentially deadly illnesses, such as heat exhaustion and heat stroke. Hot temperatures can also contribute to deaths from heart attacks, strokes, and other forms of cardiovascular disease. Heat is the leading weather-related killer in the United States, even though most heat-related deaths are preventable through outreach and intervention (see EPA’s Excessive Heat Events Guidebook at: www.epa.gov/heat-islands/excessive-heat-events-guidebook).
Unusually hot summer temperatures have become more common across the contiguous 48 states in recent decades…extreme heat events (heat waves) have become more frequent and intense… and these trends are expected to continue. As a result, the risk of heat-related deaths and illness is also expected to increase.[2] The “urban heat island” effect accentuates the problem by causing even higher temperatures in densely developed urban areas. Reductions in cold-related deaths are projected to be smaller than increases in heat-related deaths in most regions. Death rates can also change, however, as people acclimate to higher temperatures and as communities strengthen their heat response plans and take other steps to continue to adapt.
“Certain population groups already face higher risks of heat-related death, and increases in summertime temperature variability will increase that risk. The population of adults aged 65 and older, which is expected to continue to grow, has a higher-than-average risk of heat-related death. Children are particularly vulnerable to heat-related illness and death, as their bodies are less able to adapt to heat than adults, and they must rely on others to help keep them safe. People with certain diseases, such as cardiovascular and respiratory illnesses, are especially vulnerable to excessive heat exposure, as are the economically disadvantaged. Data also suggest a higher risk among non-Hispanic Blacks.”
Trent, CA Dept. of Health Services on Heat-Related (HR) Illness: “HR illness is described according to three stages of increasing severity:
- Heat cramps. Mild and easy to treat, this level involves fevers generally under 102 degrees Fahrenheit.
- Heat exhaustion: Involves fevers over 102 degrees Fahrenheit, often with vomiting, diarrhea, and fatigue.
- Heat stroke: A severe and life-threatening failure of body’s ability to cool (e.g., sweating ceases), with fevers over 104 degrees Fahrenheit. Heat stroke can result in organ and neurologic damage and lead quickly to death.” (p. 3)
“Exertional heat stroke tends to occur among younger (under 50 years old), healthier persons who develop heat stroke after strenuous activity and inadequate hydration. The result is dehydration and electrolyte imbalance. Exposures may involve work or recreational activities outdoors.
“Classic heat stroke tends to occur among persons who are older (over 50 years old), frail, and with chronic diseases. They may take medications, have psychological or cognitive problems, and live alone. They are assumed to have a compromised thermoregulatory response due to their age, illnesses, and medications. They generally are not in an air conditioned space when discovered with heat stroke symptoms or deceased.” (p. 5)
(Trent, Roger B., Ph.D. (CA Dept. of Health Services). Review of July 2006 Heat Wave Related Fatalities in California. Sacramento, CA: Epidemiology and Prevention for Injury Control Branch, California Department of Health Services, May 2007.)
Associated Press (Anita Snow and Kendria Lafleur), Mishmash of how US heat deaths are counted complicates efforts to keep people safe as Earth warms.” 8-13-2023:
“….Even when it seems obvious that extreme heat was a factor, death certificates don’t always reflect the role it played. Experts say a mishmash of ways more than 3,000 counties calculate heat deaths means we don’t really know how many people die in the U.S. each year because of high temperatures in an ever warming world.
“That imprecision harms efforts to better protect people from extreme heat because officials who set policies and fund programs can’t get the financial and other support needed to make a difference….Currently, about the only consistency in counting heat deaths in the U.S. is that officials and climate specialists acknowledge fatalities are grossly undercounted…
“ ‘It’s frustrating that for 90 years public health officials in the United States have not had a good picture of heat-related mortality because we have such a bad data system,’ said Dr. David Jones, a Harvard Medical School professor who also teaches in the epidemiology department at the Harvard T.H. Chan School of Public Health.
“There is no uniformity among who does the counting across U.S. jurisdictions. Death investigations in some places might be carried out by a medical examiner, typically a physician trained in forensic pathology. In other locales, the coroner could be an elected sheriff, such as the one in Orange County, California. In some small counties in Texas, a justice of peace might determine cause of death. Utah and Massachusetts are among states that do not track heat-related deaths where exposure to extreme heat was a secondary factor.
“The CDC, which is often several years behind in reporting, draws information on heat deaths from death certificate information included in local, state, tribal and territorial databases. The CDC said in a statement that coroners and others who fill out death certificates ‘are encouraged to report all causes of death,’ but they may not always associate those contributing causes to an extreme heat exposure death and include the diagnostic codes for heat illnesses.
“Hess, the Arizona coroner [Pima County medical examiner], said determining environmental heat was a factor in someone’s death is difficult and can take weeks or even months of investigation including toxicological tests. ‘If someone was shot in the head, it’s pretty obvious what happened there,’ Hess said. ‘But when you find a body in a hot apartment 48 hours after they died, there is a lot of ambiguity.’ Hess noted that Pima County this year began including heat-related deaths in its tally of environmental heat fatalities….”
