Breathe Easy

When feeling congested it’s easy to resort to breathing through your mouth, but did you know that could be making your congestion worse and even increase the likelihood of catching colds and chest infections?

That’s because, according to GP, Dr Roger Henderson1, the nose produces a gas called nitric oxide which is both anti-viral and anti-bacterial – so can help fend off nasty bugs2. So, even when bunged up, it’s best to try and breathe in and out through your nose.

According to our recent survey3, 13%3 of British adults typically breathe through their mouths, and this increases to 18%3 when asleep. And of these self-confessed mouth-breathers, nearly one in three (31%)3 admit they experience nasal congestion often, with 38%3 saying it keeps them up at night.

To help the nation breathe easy, we asked leading GP, Dr Roger Henderson1 what effect nasal breathing can have in our fight against congestion. Read the Olbas Breathe Easy Guide here which offers tips to help big and little noses when congestion hits.
