Dryness associated with cold air is the root of many breathing issues. Bronchial passages start to dry out and expose people to illness and breathing difficulties. By passively humidifying each breath, ColdAvenger face masks mitigate the symptoms associated with cold weather induced asthma, COPD, and Cystic Fibrosis.
Besides humidifying, ColdAvenger masks also gently warm inhaled air to help maintain core temperatures. This allows blood in the body to maintain total flow, instead of concentrating on keeping vital organs warm. Because the body isn't working as hard to keep warm, it allows blood to flow to fingers, toes, and the brain. This keeps you warmer overall (much like wearing an extra base layer) and keeps you thinking clearly in the coldest of conditions.
