How to adjust changeable mood in foggy days?

Me too, but I'm used to it now. I do this: 1. It will be much better to open the window first every morning to let the indoor air circulate. If there is fog, try not to go out. If you have to go out, you should do personal protection. If there is fog, try not to smoke indoors. 4. Pay attention to drink plenty of water in foggy days. 5. Eat more fruits and vegetables. thank you
