The air in サンパウロ feels a bit heavy today, like the city is wrapped in a gauzy blanket. It’s not a sharp, smoky sting, but more of a dull thickness that makes breathing feel slightly laborious, as if the air has lost its usual lightness.

It’s probably not the best day for a long, strenuous jog or a bike ride along the busier avenues, especially if you plan to be out for a while. You could still step out for a quick errand or a short, gentle walk, but you might notice your lungs working a touch harder than usual. Opening the windows wide for a full airing out might not help much right now.

If you have little ones, or if you’re an older person, or if you or someone in your home has a sensitive chest or a heart condition, it would be wise to take it easier today. That heavy feeling can be more of a burden for them, so keeping the windows closed and the car’s windows up while driving could make a real difference.

The good news is that this sort of day usually passes, and the air will clear again soon. For now, just take it a bit slower, maybe choose a quiet indoor activity, and know that tomorrow will likely feel fresher on the lungs.
