 Summer is fully underway, and that means heat and humidity that comes with it here on Delmarva. Staying cool and comfortable isn't always easy, but officials from the Division of Public Health offer some tips. The best thing people can do, of course, on a hot day is find an air-conditioned shelter. If they don't have one in their home, they can go to a library, mall, theater, a house of worship, or other public locations. We also recommend, even in those locations, staying on the lowest floor possible and not relying on a fan alone for your primary cooling device.
