At least 12 people have died as a result of heat-related issues in parts of the United States over the last few weeks.

Last week, the National Weather Service Weather Prediction Center issued an excessive heat warning for 28 states, warning that temperatures nearing 100 degrees Fahrenheit will “increase the risk of heat-related illnesses.”

Several states and cities, including New York and Boston, issued heat-related warnings, advising residents to stay inside as much as possible and to be aware of heat-related issues.

According to WNBC in New York, the city’s medical examiner’s office announced that one person died due to heat exposure over the weekend. The individual, who was not identified by the medical examiner’s office, already had some underlying medical issues, such as heart disease, according to WNBC.

Similarly, at least one heat-related death occurred in Pennsylvania and Dallas over the weekend.

According to WCAU news in Philadelphia, the Lehigh County Coroner’s Office announced last Thursday that a 73-year-old man died from “excessive heat exposure, complicated by underlying medical conditions.”

The Dallas County Department of Health and Human Services (DCHHS) announced on Thursday that a 66-year-old female Dallas County resident with underlying health conditions died as the county’s first heat-related death this year.

“We are deeply saddened to report our first heat-related death this season,” DCHHS Director Dr. Philip Huang said in a press release. “We are experiencing extreme heat this season, which reminds us how important it is to take every precaution possible.”

The Pennington County Sheriff’s Office in South Dakota announced that a hiker, Maxwell Right, 22, died after collapsing and running out of water on an unmarked trail.

“Maxwell Right, 22, of St. Louis, Missouri, collapsed and died as a result of suspected dehydration and exposure. His 21-year-old Missouri companion was located by Park Rangers and flown to Monument Health by Life Flight air ambulance “On July 21, the sheriff’s office announced the arrest.

The Maricopa County Public Health Department in Arizona released a report on the number of heat-related deaths in the county since the beginning of 2022. As of July 16, there had been at least 29 confirmed heat-related deaths, according to the report. According to KNXV-TV in Arizona, there were at least 12 heat-related deaths in Maricopa County between July 10 and July 16.

Jonathan Porter, chief meteorologist for AccuWeather, told Newsweek last week that the current wave of high temperatures across the United States is expected to last several days.

“There does not appear to be much of a break in the heat or any significant opportunity for drought-busting rain on the horizon for the Southern Plains and the places experiencing extreme drought conditions.” “AccuWeather expects above-average temperatures to persist over Texas and the Southern Plains through August,” Porter told Newsweek. “In general, it appears that the dry and hot weather will continue, as AccuWeather meteorologists have accurately predicted for months.”

According to a report commissioned last year by the city’s health department, New York City sees an average of ten heat-related deaths per year. According to the report, a lack of home air conditioning “continues to be an important risk factor for heat stress death.” It is not known whether the person who died of heat exposure Saturday had access to air conditioning.
