Why do we shiver when we are cold?
You're standing outside on a winter morning, and suddenly your body starts doing something weird. Your muscles shake. Your teeth chatter. You didn't decide to do this — it just happened. What's going on?
Your body is an incredibly precise machine that runs best at exactly 98.6°F (37°C). Too hot or too cold, and your cells can't do their jobs. When cold air touches your skin, temperature sensors in your body sound the alarm: "We're losing heat!"
