Anyone else struggling with the air quality?

For 4 days this past week, the air quality in my city was at 165 (unhealthy for sensitive groups). I was diagnosed with Hashimotos in December of last year so this is my first time experiencing poor air quality since then.

The air has been better since about midday yesterday, but I still feel awful, almost like im recovering from a cold. I am sore, fatigued, nauseous, anxious and feel super tense/jumpy.

Does anyone else struggle with this? Should I look into buying a respirator for the next time this happens?
