Lastly, knowing when to call it quits is of the utmost importance. When your core temperature reaches 95 degrees Fahrenheit, you’re hypothermic. Your body will begin to shiver to generate heat, and you’ll likely be unable to do much of anything. As your core temp drops beyond that you’ll encounter muscle stiffness, followed by involuntary contractions, and confusion. Being aware of these symptoms is the first step to preventing them. Being a “tough guy” (or gal) is all too often associated with motorcycling, but being cold can kill you, so putting aside these attitudes in exchange for some basic knowledge could very well save your hide.
