Older adults, very young children, and those who are sick or overweight are at a higher risk for heat-related illness. [10] The chronically ill and elderly are often taking prescription medications (e.g., diuretics , anticholinergics , antipsychotics , and antihypertensives ) that interfere with the body's ability to dissipate heat.
Heat exhaustion is a precursor to heat stroke, a severe form of heat-related illness. Heat stroke is more likely than heat exhaustion to cause pallor, hot and dry skin, syncope, and dysfunction of the central nervous system (e.g., altered mental status, loss of spatial awareness, loss of bodily movement control, seizures, etc.).
Heat stroke or heatstroke, also known as sun-stroke, is a severe heat illness that results in a body temperature greater than 40.0 °C (104.0 °F), [4] along with red skin, headache, dizziness, and confusion. [2] Sweating is generally present in exertional heatstroke, but not in classic heatstroke. [5] The start of heat stroke can be sudden or ...
A study from the Centers for Disease Control and Prevention published in April found that there were nearly 120,000 heat-related emergency room visits in 2023, and 90% of them happened between May ...
The CDC defines “extremely high” as being in the top 5% of busiest days for heat-related illnesses over the last five years, from 2018 through 2023. ... Other patients have been older adults ...
This sobering statistic underscores a 117 percent surge in heat-related deaths since 1999, with over 20,000 lives claimed by blistering temperatures over the past two decades.
An early stage of hyperthermia can be "heat exhaustion" (or "heat prostration" or "heat stress"), whose symptoms can include heavy sweating, rapid breathing and a fast, weak pulse. If the condition progresses to heat stroke, then hot, dry skin is typical [ 2 ] as blood vessels dilate in an attempt to increase heat loss.
