The Maryland Department of Health issued an alert on Thursday, July 13 advising of the man's death, though few details were released.
Each year, health officials monitor temperature conditions and incidents of heat-related illness and death between May and September, officials said.
"Marylanders should never leave children or pets in a car for any time during hot weather, even with the windows cracked, and are encouraged to check on elderly neighbors or relatives to ensure they have a cool place to stay," they continued.
The groups at the highest risk of suffering from a heat-related illness are residents under the age of 5 or over 65, as well as people with underlying illnesses.
In 2022, Maryland reported five heat-related deaths.
"We are very saddened to report our first heat-related death of the season,” Deputy Secretary for Public Health Services Nilesh Kalyanaraman said. “As we experience more hot days like today, this tragedy reminds us of how important it is to take every precaution to avoid overheating.
"Also, be sure to check on family and neighbors who are at risk for heat-related illness.”
