Cold Weather Workouts Burn More Calories: Study

If you’re heading outside for a frosty workout, there are a few things to keep in mind. To maximize the benefits, you want to be working out in a temperature somewhere between the high 40s and high 50s (experts say 50–53°F is ideal). When the weather drops below this, you’ll have to consider a host of other issues—like investing in cold-weather workout gear or navigating icy or snowy surfaces, which can mean poor footing and a greater risk of falling. Even at moderately cold temperatures, it takes your body some time to warm up. This can lead to an increased possibility of injury if you go too hard, too soon, warns Geisel.

The solution: Do some dynamic stretching before heading out. Then, once you’re outside, start slowly and give your body ample time to adjust.

Finally, you need to be cognizant of how long you’re outside after your workout—especially if your clothes are soaked in sweat. Even at a relatively mild 41°F, heat loss in wet clothes can be double that of dry conditions. This puts you at an increased risk of hypothermia, which can develop when heat loss exceeds heat production, causing a drop in core temperature. Early symptoms include feeling chilled, severe shivering, and feeling confused. If you start noticing any of these signs, head inside immediately.
