Cold, dry air causes the upper airways to narrow, which makes it harder to breathe and it can irritate the airways and lungs and increase your risk of catching a cold or a virus.
When you breathe air in through the nose, tiny hairs in the nasal passages help filter out germs as air passes through to the sinuses. Nasal breathing slows down air intake and provides more time to warm and humidify the air before it reaches the lungs.
Warmer air means the bronchial tubes are more open, resulting in better oxygen intake.
When air is breathed in through the mouth it goes directly to the lungs without being filtered, warmed or humidified.
During the day, protect yourself by wearing a mask or scarf and always breathe through your nose while outdoors.
At night, apply sleepQ+ to your lips to ensure you maintain nasal breathing while you sleep.
