I toured Stanford Bridge in the middle 2010s, they actually found uncomfortable away dressing rooms weren't the most effective as it either got the other team to go out and start warming up or riled them up.
When Mourinho started he brought in a sports psychologist who made the dressing rooms slightly heated with light pink walls and a comforting atmosphere. They ended up going 2+ years without a loss at home after that.
