Relax, it helps with patience and health
Listen to music, make conversation.
Boredom
Poker is sometimes boring. Not often, but it can be. Don’t play looser for fun, as negative EV.
Online: Play more tables, listen to music.
Live: Conversation, look around, read book on phone (productive), listen to music
