I am not advocating smoking, but perhaps if people took that smoke break as a short walk break it would help.

Back in Australia I had a small team of people I managed in retail. A couple of them smoked, but I sent them all out on "smoke breaks" and covered them on the shop floor. Especially when really busy, it made a big difference to their day.

sometimes it is good to get away for a bit but then if it is stress that needed to be worked out all one does is delay the inevitable.

I think a lot of people have delayed the inevitable and those who have been locked-up due to Covid restrictions, have been forced to face it.

I am okay under "normal" stressful conditions, but I have to pay more attention when things start to mount up rapidly. One of the first skills to learn is identifying it early.
