Abstract: Mood regulation enclosures and methods of use thereof are disclosed. The mood regulation enclosures include an interior space to contain a user, a closeable aperture and physical barriers which effectively sensorily separate the user from the outside environment. A person observing the enclosure from outside is unable to ascertain an activity of the user within. The enclosure may be specifically configured for aggression release or for passive relaxation. The method of regulating a mood includes providing a mood regulation enclosure as described hereinabove, allowing a user to enter the enclosure so that the user is effectively sensorily separated from the outside environment and preventing a person observing the enclosure from outside from ascertaining an activity of the user within.
