Breaks
Time for food, dog walking & coffee brewing
People will not take a break unless you call one, and a tired group is the fastest route to a session that falls flat.
Breaks are scheduled pauses where participants step away from the screen. That sounds obvious but online they carry more weight than in a physical room. In person people can stretch, refill coffee, and chat without anyone stopping the session. Online the only way to do any of that is to stop the session.
Video call fatigue is real and it compounds through a day. Attention drifts faster online than in a room, and people who are tired do not say so; they just quietly disengage. A break at the right moment resets the room.
