1. A bed exit warning system for monitoring a user on a bed including a mattress, the system comprising:
a base station configured to issue a warning that the user is about to get out of the bed; one or more sensors placed in a position selected from one of beneath the mattress and in the mattress, and configured to continuously and directly measure one or more physiological characteristics of the user; and a processor configured
to determine a likelihood that the user is about to get out of the bed from changes in the measured one or more physiological characteristics, andto notify the base station of the likelihood, wherein the processor is configured to determine the likelihood by comparing the changes in the measured one or more physiological characteristics to previously collected one or more physiological characteristics during which bed exits by the user occurred.
