Stay Cool & Safe: Tips as Heat Wave Pummels U.S.

2024-06-19

WEDNESDAY, June 19, 2024 -- A record-breaking heat wave is spreading across the United States, baking the Northeast and Midwest with high temperatures and sweltering humidity.

Everyone is at risk for heat-related illness as body temperatures rise, experts warn.

Heat stroke, heat exhaustion and heat cramps can fell anyone who overheats. People who are outdoors for too long also might develop a heat rash or sun poisoning, which occurs with severe sunburn.

“Sadly, heat-related deaths and illnesses happen every year,” said Diane Calello, executive and medical director of the New Jersey Poison Control Center at Rutgers New Jersey Medical School.

The people most vulnerable to heat-related illness include children, older adults, people with chronic illnesses, the disabled, people without air conditioning and those who spend long times outdoors, experts say.

Signs of heat exhaustion or heat stroke can include painful cramps, fever, rapid heart rate, loss of appetite, nausea, vomiting, headache, fatigue, weakness, confusion, agitation, lethargy, hallucinations, delusions and seizures. Coma and death can occur if left untreated.

To stay safe, weather and health experts offer the following safety tips:

People also should be aware of the heat risk posed by illicit and prescription drugs, Calello said in a Rutgers news release.

Heat stroke “not only occurs when temperatures reach dangerous levels, but also from the use of certain therapeutic medicines, recreational [legal] drugs and illegal substances,” Calello said. “These can prevent the body from cooling down through sweating. Too often, this results in serious complications, including drug-induced fever, dehydration and death.”

Medicines like antidepressants, antihistamines, diuretics, antipsychotics and stimulants can cause heat-related complications, Calello said.

People should talk with their doctor, pharmacist or regional poison control center to see whether the drugs they are taking increase their sensitivity to heat, she said.

Those taking illicit drugs might not realize they are developing a heat-related illness, Calello added.

“Excessive heat combined with certain substances like ecstasy [MDMA], cocaine, methamphetamine, alcohol and heroin can be deadly,” Calello said. “Being under the influence of these substances can make it hard to recognize symptoms of overheating.”
