Dear Sydney: some tips for wearing masks....

* Invest in finding the right mask for your face. Some material may be irritating, some designs may be the wrong shape for your head, some ties may hurt your years. If you’re going to be wearing a mask every day have a think about what works best for you

* Get the seal tight to your face: it shouldn’t be bagging around your chin or cheeks.

* You can stop glasses fogging up by making sure the seal of the mask is close to your skin of your nose or using a little cloth tape to stick it down

* Brush your teeth before leaving the house. Chew gum or suck on a mint. Don’t eat anchovies and onion just before putting a mask on
