Physically go out to do non-work related tasks. Go to stores, go buy a drink, jogging, biking, go around the neighborhood, listen to non-work podcasts, video call friends, etc.

Actually here’s a thought. Someone can set up a service like meetup.com but for virtual social meetings. It sets up schedules for gatherings that people can join. It’s a good way to pull people away from work in after hours. It can even be called videoup.com
