Is It Ever Too Cold to Exercise Outdoors?

It may surprise you that scientists have actually suggested that no temperature is too cold when it comes to exercising outdoors. It’s true. Almost everyone is safe to work out in cold weather. You should probably choose some heat generating high-intensity workouts instead of a more chill workout like yoga, but your body will do its darndest to maintain a core temp of 98.6 degrees no matter what you choose to do—as long as we follow a few necessary precautions.

In fact, according to Dr. Castellani, lead author of a 2012 paper on Health and performance challenges during sports training and competition in cold weather, it turns out that even though cold can be thought of as dangerous and uncomfortable, more people are injured exercising in the heat than exercising in the cold.

One of the great thing about our human meat sacks is that when we exercise, our bodies generate enough heat to make us feel much warmer than it really is

One of the great things about our human meat sacks is that when we exercise our bodies generate enough heat to make us feel much warmer than it really is outside. Research suggests no matter what the thermometer says, the body will work hard to maintain the healthy and happy temperature of 98.6˚F. That work backfires on us a little since it can lead to a higher level of perceived exertion, but we’ll get into that later.

What Happens When We Get Cold?

When your core (or your torso) is nice and warm, it allows blood to flow to the extremities. But when your core gets too cold, your body stops sending as much blood to the extremities and hoards it for your vital organs and brain. So, what is the best way to keep your hands and feet warm? Heat up your core through physical activity!

It’s not just the core heating up that keeps us safe either. The body has many mechanisms that protect us from the cold. Even that runny nose is helping to keep you safe. When you are cold, the inside of your nose moistens itself to help humidify the cold, dry air that you are inhaling. The runny nose part comes from the excess fluids that end up dripping out of your nostrils.

We’ve all probably heard a story of someone’s cousin’s friend who froze their lungs while exercising outside. Well, please don’t give any credence to that tale or worry about icy cold air hitting your lungs because it is basically impossible for cold air to damage your lungs. Kenneth W. Rundell, the director of respiratory research and the human physiology laboratory at Marywood University says that...
