It’s important for everyone’s safety that we wear our masks properly, covering nose and mouth.
If you wear glasses, you have likely experienced problems with fogging while using your mask. There are some things that you can do to help reduce fogging:
1) Use a form fitting mask. Ones with flexible nose-bridge strips can help.
2) Wash your glasses with soapy water. A thin film left behind can reduce fogging.
3) Use an anti-fogging spray or wipe.

If your mask gets uncomfortable from moisture build-up during workouts, bring along some extras so you can exchange a damp mask for a dry one.
