This 1 Lifestyle Change Can Drastically Reduce Your Risk Of Catching A Cold

Breathing in cold, dry air outside (or even in your home) can make you more susceptible to catching a cold. And it’s all because of the way our noses are set up to protect us.

When the air outside the nose is too dry, it causes the nose to work harder to humidify the air you breathe in, and it can’t always keep up. 

Rhinologist and sinus surgeon Dr. Peter Hwang, head of the Stanford Sinus Center and SoundHealth founder, told HuffPost, “Healthy nasal function relies on both proper anatomy to enable good airflow and a well-hydrated mucus layer which helps to keep the nose humidified and clean.”
