It’s something you probably think about before you get ready to go outside to exercise.

What’s the weather out there? Is it hot? Is it cold? Is it raining? Does it really matter?

The answer is YES! Weather can impact your outdoor workout in many ways. Heat, cold, rain, and wintry precipitation all have important effects on the human body. In many cases, clothing and other gear can lessen the effects; in other cases, it can be downright dangerous to be outside. Understanding the science of weather and the human body can help you be prepared to have the best outdoor workout possible or know when its time to hit the gym.
