With extremely hot and humid weather covering a good part of the eastern US this week, it is important to know what that kind of temperature extreme can do to the human body. I’ve already heard a few stories about people who were affected by the heat as they worked outside today. Time posted a story that explains how heat illnesses are caused and how they can affect the human body over time. Make sure you understand how to spot heat stroke and other heat-related illnesses and treat them as soon as you see them. Better yet, take care of yourself and don’t get sick in the first place! Heat can also affect livestock and pets, so make sure that you can keep them cool as well.
