 They live in the communal House and share cooking and cleaning chores among themselves, which usually provides plenty of tension.Housemates are forbidden to sleep during daylight hours (unless unwell) - Big Brother plays the wake-up call persistently in the morning if housemates do not wake up and will play an alarm clock noise into the house if a housemate falls asleep during the day.Housemates must also live by the fundamental rules of Big Brother; if the rules are broken it can result in formal warnings, various punishments or even a housemate's removal from the House.
