Abstract
One variation of a method—for controlling a breathing mask comprising a flow control module configured to mate to nostrils of a user and comprising an actuator configured to adjust obstruction to airflow out of the flow control module—includes: accessing a wake alarm time; accessing a sleep delay duration; at a first time, receiving an indicator that the user is preparing for sleep; in response to receiving the indicator, triggering the actuator to transition from a minimum-restriction position toward a maximum-restriction position at a second time succeeding the first time by the sleep delay duration, the actuator minimally obstructing airflow out of outlet port in the minimum-restriction position and maximally obstructing airflow out of outlet port in the maximally-restriction position; and, prior to the wake alarm time, triggering the actuator to transition back to the minimum-restriction position.
