PROBLEM TO BE SOLVED: To provide a technique for suppressing the occurrence of disturbance of consciousness. One aspect of the present invention relates to a first estimation unit that estimates body fluid amount information, which is information on the amount of body fluid existing in a user's head, and an oxygen supply amount, which is the amount of oxygen in the user's brain. A second estimation unit that estimates oxygen supply amount information, which is information, and a pressurizing unit that is attached to the user and applies pressure according to the estimation result of the first estimation unit and the estimation result of the second estimation unit. It is a consciousness disorder reducing device including an oxygen supply unit that supplies oxygen to the user based on the estimation result of the second estimation unit.
