1. A method of maintaining an affective state in a subject (12) comprising:

  • measuring one or more physiological parameters of the subject (12),calculating, using the measured parameter(s), a value (26) representing a relaxation state of the subject (12),determining if the calculated value (26) is below a lower threshold (20) or above an upper threshold (22), wherein the lower threshold (20) represents the lower limit that the subject (12) is allowed to reach and at which the subject (12) becomes too relaxed and wherein the upper threshold (22) represents the maximum alertness that the subject (12) is permitted and at which the subject (12) becomes too aroused, andgenerating an output to the subject (12), comprising generating a first output for initiating to reduce relaxation if the calculated value (26) is determined to be below the lower threshold (20) and generating a second output for initiating to increase relaxation if the calculated value (26) is determined to be above the upper threshold (22), the second output being different from the first output.
