Wearing a mask may can affect how you breathe. You might find yourself taking shallow breaths, or even holding your breath. This can cause you to breathe in more carbon dioxide, which can cause headaches and nausea.
Moving around while wearing a mask can also be fatiguing, because you have to breathe harder to do regular tasks.
And masks may make you feel claustrophobic and anxious, which cause hyperventilating (taking rapid breaths). This will make you feel dizzy, lightheaded, cause numbness and tingling of your lips, and possibly spasms in your hands and feet. You might be hyperventilating and not even realize it.
If you notice any of these symptoms, try some mindful breathing exercises or find a place to be alone without your mask for a few moments while you return your breath to normal.
If you find yourself with an aching head after beginning to wear a mask day in and day out, it could be related to two things: caffeine intake and hydration.
