Abstract: A sleep-retraining method includes monitoring, via a sleep-retraining beanie, electrical brain-activity of a user during an initial sleep session. The electrical brain-activity is reflected in the form of brain-activity data. The method further includes receiving, via an electronic device, physical-activity data for the user that is indicative of a physical activity of the user occurring after the initial sleep session. The method further includes, based on the brain-activity data and the physical-activity data, suggesting an optimal sleep session for the user that has an improved sleep quality relative to the initial sleep session.

Abstract: A wearable air treatment system includes a user interface configured to be coupled about at least a portion of a face of a user. The wearable air treatment system also includes an air treatment module coupled to the user interface. The air treatment module in turn includes an air inlet configured to receive ambient air therethrough. A light source is positioned distal of the air inlet and is configured to emit light to treat at least a portion of the received ambient air. The air treatment module also includes an air outlet positioned distal of the light source. The air outlet is configured to direct at least a portion of the treated ambient air towards an interior of the user interface.

Abstract: A method includes generating, by a control system, a plurality of sleep scores for a user, wherein the plurality of sleep scores for the user are associated with a plurality of days. The method also includes receiving, by the control system from an external device, a plurality of activity indicators, wherein the plurality of activity indicators are associated with the plurality of days. The method also includes determining, by the control system based on the plurality of sleep scores and the plurality of activity indicators, correlations between the sleep scores and the plurality of activity indicators. The method also includes generating, by the control system, a visual presentation, wherein the visual presentation indicates the correlations between the plurality of sleep scores and the plurality of activity indicators. The method also includes causing presentation, by the control system via a display device of a user device, the visual presentation.
