If a wounded survivor comes to you and crouches, heal them. If you unhook someone, don’t automatically assume they want healing. If they want to be healed they will follow you. Don’t follow them unless they are immediately heading for a nearby gen that’s close to repaired. Don’t be pushy with healing others at the expense of getting objectives done. Tea bagging next to me to heal while I’m busy fixing a gen is super un-helpful. Want to help? Fix the gen! Maybe I don’t want to heal because I’m running a perk like resilience that only works when you’re wounded. Maybe I have Second Wind. Also, if Nurse is the killer, just assume that it’s unsafe to heal near her within her terror radius.
