The air in São José dos Campos feels a bit heavy today, like a mild haze is hanging around. Breathing is still perfectly fine for most people, but you might notice a slight thickness in the air if you step outside.

It's not the best day for a long, strenuous jog or bike ride, but a gentle walk or some light gardening is absolutely fine. Keep the windows mostly closed, especially during the busier parts of the day, as the air is just a little muggy and still.

Children and anyone with asthma or sensitive lungs might want to take it a bit easier and avoid prolonged outdoor exertion. The same goes for older folks or those with heart conditions, just a more relaxed pace today.

Don't worry, it's nothing serious at all, just a touch of stillness in the atmosphere. By tomorrow, a breeze should come through and freshen everything up, so just take it easy today and you'll be just fine.
