A method for automatically monitoring consciousness of a person and triggering an alarm if the monitored person is not in a state of full consciousness is provided. The method comprises the steps: monitoring at least one aspect of the behavior of the person (S1) analyzing whether the monitored behavior of the person corresponds to an expected behavior for a state of full consciousness or not (S2, S2&prime) triggering an alarm if the analysis results in that the detected behavior does not correspond to the expected behavior (S3).
