“It’s hot, really hot,” said Leah Henderson.

“When it’s very hot and humid, it may not even take 20 or 30 minutes for people to feel the effects of the heat,” said Dr. Danielle Warren, associate medical director of Carroll Hospital’s emergency department.

WJZ spoke with Dr. Danielle Warren of Carroll Hospital, who warned of heat-related illnesses. Some people experience dizziness, nausea and shortness of breath. The symptoms of heat stroke are more severe and include confusion and loss of consciousness.

“You should stay indoors at least as long as you were outdoors to hopefully minimize symptoms and health risk,” Dr. Warren said.

According to Dr. Warren, her hospital sees between five and ten patients with heat problems every day.

Her most important tips are to limit the time spent outdoors and to drink plenty of fluids.

She says anyone with serious health problems should stay home.
