The nose is the gateway to your immune system.

​Looking for the best ways to keep yourself healthy this winter?

Close your mouth and breathe through your nose!
The function of the nose is to filter and warm air as well as removing bugs. Your nostrils are lined with tiny hairs called cilia which constantly bring bacteria and viruses back out of your body to stop you getting sick.

Interesting note: breathing through your nose also stimulates the release of nitric oxide from the nasal sinuses, which effectively dilates (or widens) the blood vessels to all the organs and tissues of the body. This allows better oxygen absorption and improved efficiency.
Chronic mouth breathers commonly suffer from anxiety and chronic pain. These symptoms can improve with breathing pattern retraining.  

Travelling this winter? 
When travelling by plane, the cilia can dry out and cause this protective barrier to fail. Keep your nasal cilia hydrated with saline sprays every 2 hours before and during your flights.
