While in the room, the housemates must wear all white and drink and eat white food. Big Brother also keeps bright white lights on throughout the day.
Luke S has compared the room to a "mental institute".
"What time is it? I can't stay in here much longer," said Sara.
"It's driving me insane, I can't stay in here tonight."
The White Room housemates will take part in challenges with the other housemates during the week as part of a shopping task.
Big Brother continues daily on Channel 5.
