While the heat wave and virtual sauna over the Northeast and Midwest has broken few records, multiple days and nights of high humidity and light winds with the event are leaving an impression.
For many locations, Thursday was day five of the heat wave, which began last weekend. And in some areas there are a couple more days of sweltering to go.
"The duration of the heat index being 97 to over 100 degrees has diminished the population's ability to respond to the heat," Dr. Kevin Baumlin, associate professor and vice chair for Clinical, Operations, Quality and Finance in the Department of Emergency Medicine at the Ichan School of Medicine, said. "We urge people to drink lots of fluids and go to air conditioning if possible."
Mostly older people over the age of 65 are being seen for heat-related illnesses in the emergency department at Mount Sinai Medical Center in New York City, Baumlin said. Twelve patients were treated Tuesday and Wednesday.
Patients with heat illnesses are presenting symptoms of weakness, dizziness, dehydration and nausea, Baumlin said.

"Several older people in our geriatric emergency department have shown signs of minor confusion," he said.
The heat wave is hitting around what is typically the hottest part of the summer, when the days are long, the sun is intense and the nights are short. (On Thursday, Alaska was the only state that did not reach 90 degrees).
With limited time to cool down at night, temperatures will get a jumpstart during the midday.
As anticipated by AccuWeather.com meteorologists, record high temperatures have been scarce, while the nights have been especially rough for those without air conditioning, especially in the major cities.
