Furthermore, deaths can occur from exposure to heat (either as an underlying cause or as a contributing factor) that is not classified as extreme and therefore is often not recorded as such.The orange line shows deaths for which heat was listed as the main (underlying) cause.
The blue line shows deaths for which heat was listed as either the underlying or contributing cause of death during the months from May to September, based on a broader set of data that became available in 1999. As a result, data from earlier than 1999 cannot easily be compared with data from 1999 and later. This graph presents summer (May to September) death rates from 1999 to 2014 for three population groups in the 50 states and the District of Columbia. ![]() For example, during a severe heat wave that hit Chicago between July 11 and July 27, 1995, 465 heat-related deaths were recorded on death certificates in Cook County. However, studies that compared the total number of deaths during this heat wave (regardless of the recorded cause of death) with the long-term average of daily deaths found that the heat wave likely led to about 700 more deaths than would otherwise have been expected. Differences in estimated heat-related deaths that result from different methods may be even larger when considering the entire nation and longer time periods. Overall, a total of more than 9,000 Americans have died from heat-related causes since 1979, according to death certificates. Overall, the interaction of heat and cardiovascular disease caused about one-fourth of the heat-related deaths recorded in the underlying and contributing causes analysis since 1999 (see Figures 1 and 2). For example, studies of the 1995 heat wave event in Chicago (see example figure) suggest that there may have been hundreds more deaths than were actually reported as heat-related on death certificates. This limitation, as well as considerable year-to-year variability in the data, make it difficult to determine whether the United States has experienced a meaningful increase or decrease in deaths classified as heat-related over time. Hot temperatures can also contribute to deaths from heart attacks, strokes, and other forms of cardiovascular disease. 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. California Heat 1995 Professional Identifies TheEvery death is recorded on a death certificate, where a medical professional identifies the main cause of death (also known as the underlying cause), along with other conditions that contributed to the death. Dividing the annual number of deaths by the U.S. One method shows deaths for which excessive natural heat was stated as the underlying cause of death from 1979 to 2014. The other data series shows deaths for which heat was listed as either the underlying cause or a contributing cause, based on a broader set of data that, at present, can only be evaluated back to 1999. For example, in a case where cardiovascular disease was determined to be the underlying cause of death, heat could be listed as a contributing factor because it can make the individual more susceptible to the effects of this disease. Because excessive heat events are associated with summer months, the 19992014 analysis was limited to May through September. This graph includes deaths due to heart attacks, strokes, and other diseases related to the circulatory system. Figure 2 shows death rates for the overall population as well as two groups with a higher risk: people age 65 and older and non-Hispanic blacks. Like the underlying and contributing causes analysis in Figure 1, Figure 2 is restricted to the summer months, and it uses data that are available from 1999 to 2014. In many cases, the medical examiner might classify the cause of death as a cardiovascular or respiratory disease, not knowing for certain whether heat was a contributing factor, particularly if the death did not occur during a well-publicized heat wave.
