Hike, Climb, Mountaineer? Exercise in the Cold? 14ers in Winter? A Heat Exchange Mask Helps
The cold makes it harder to bring in oxygen and have that oxygen circulate around your body. Whether you hike, climb, backpack, exercise, or just camp, this can put unnecessary strain on your heart and lungs. Scientists have found that a heat exchange mask can help avoid these issues. I've been using one on my mountaineering and climbing expeditions for years. It's helped me keep cold-induced asthma under control as well as helped my non-asthmatic friends perform at their best when we are in extreme conditions.
