A system comprising: an electronic interface configured to receive first physiological data associated with a user during a first sleep session, second physiological data associated with the user subsequent to the first sleep session and prior to a second sleep session, and third physiological data associated with the user during the second sleep session; a memory storing machine-readable instructions; and a control system including one or more processors configured to execute the machine-readable instructions to: determine, based at least in part on the first physiological data, a sleep-wake signal for the user during the first sleep session; determine, based at least in part on the sleep-wake signal, one or more sleep-related parameters for the user during the first sleep session; determine, based at least in part on the one or more sleep-related parameters, that the user experienced insomnia during the first sleep session by comparing at least one of the one or more sleep-related parameters to a predetermined threshold; responsive to the determining that the user experienced insomnia during the sleep session, identify, based at least in part on the one or more sleep-related parameters, a type for the insomnia experienced by the user; and adjust the predetermined threshold to an adjusted threshold at least in part on the second physiological data. an electronic interface configured to receive first physiological data associated with a user during a first sleep session, second physiological data associated with the user subsequent to the first sleep session and prior to a second sleep session, and third physiological data associated with the user during the second sleep session; a memory storing machine-readable instructions; and a control system including one or more processors configured to execute the machine-readable instructions to: determine, based at least in part on the first physiological data, a sleep-wake signal for the user during the first sleep session; determine, based at least in part on the sleep-wake signal, one or more sleep-related parameters for the user during the first sleep session; determine, based at least in part on the one or more sleep-related parameters, that the user experienced insomnia during the first sleep session by comparing at least one of the one or more sleep-related parameters to a predetermined threshold; responsive to the determining that the user experienced insomnia during the sleep session, identify, based at least in part on the one or more sleep-related parameters, a type for the insomnia experienced by the user; and adjust the predetermined threshold to an adjusted threshold at least in part on the second physiological data. determine, based at least in part on the first physiological data, a sleep-wake signal for the user during the first sleep session; determine, based at least in part on the sleep-wake signal, one or more sleep-related parameters for the user during the first sleep session; determine, based at least in part on the one or more sleep-related parameters, that the user experienced insomnia during the first sleep session by comparing at least one of the one or more sleep-related parameters to a predetermined threshold; responsive to the determining that the user experienced insomnia during the sleep session, identify, based at least in part on the one or more sleep-related parameters, a type for the insomnia experienced by the user; and adjust the predetermined threshold to an adjusted threshold at least in part on the second physiological data. <EOS>
