The present disclosure, in one embodiment, is a computer-implemented method for the detection of and intervention in traumatic nightmares. In one embodiment, a user wears a watch wirelessly connected to a phone. The watch may include an accelerometer, gyroscope, and heartrate monitor. The application may monitor these sensors and intervene with haptic feedback if the application detects a traumatic nightmare. In one embodiment, the application may include a monitoring module that collects data from the watch's accelerometer, gyroscope, and heartrate sensors. The application may then estimate and record stress levels based on these sensors. The application may also include an intervention module that responds to high stress levels with haptic feedback that increases in intensity of previous efforts to intervene were unsuccessful.

According to an aspect of the invention there is provided a system for use in monitoring one or more physiological states of a user, the system comprising one or more processors configured to: receive a pressure signal representing pressure within a cushioning layer supporting at least a portion of a user and an acoustic signal representing acoustic vibrations within the cushioning layer; and determine, based on the pressure signal and acoustic signal, the one or more physiological states of the user.

Provided is a configuration capable of executing a detection test for a comfort level including the quality of sleep, which is measurable at home without requiring the measurement of brain waves or electrocardiogram. The respiratory waveform of a subject during sleep is continuously measured and recorded from the respiratory gas flow, etc., and is window-Fourier transformed at each measurement time to generate a frequency spectrum, and a bandwidth including a respiratory frequency is extracted. The index indicating the regularity of the respiratory period of the subject is also calculated at each time point during the sleep, and the time-dependency of this index during the sleep is represented as a graph. A medical device includes a sleep evaluation system equipped with a control means for performing control so that a sleep cycle repeated at a cycle of about 90 minutes is clearly observed if the comfort level including the quality of sleep of the subject is favorable.

Embodiments provide physiological measurement systems, devices and methods for continuous health and fitness monitoring. A wearable strap may detect reflected light from a user's skin, where data corresponding to the reflected light is used to automatically and continually determine a heart rate of the user. The wearable strap may monitor heart rate data including heart rate variability, resting heart rate, and sleep quality. The systems may include a processing module that generates an indicator of physical recovery based on the heart rate data. The recovery indicator may be used to determine strain related to an exercise routine, qualitative information on the user's health, whether to alter a user's exercise plan, and so forth.

In one embodiment, a method for generating a message to a friend of a user is provided, comprising: processing activity data of a first user measured by an activity monitoring device to update a value of an activity metric for the first user; identifying a change in an inequality relationship between the value of the activity metric for the first user and a value of the activity metric for a second user; in response to identifying the change in the inequality relationship, prompting the first user to generate a message to the second user.

A mattress has a first support portion configure to receive and support a first user and a second support portion configured to receive and support a second user. The first support portion and the second support portion are adjacent to each other such that the first user is capable of rolling over from the first support portion to the second support portion while sleeping on the first support portion. A sensor is configured to sense first pressure in the first support portion and sense second pressure in the second support portion. The sensor is further configured to transmit data of the first pressure and the second pressure. The controller is configured to receive the data and from the data of the first pressure and the second pressure, determine if the first user has rolled over from the first support portion to the second support portion.

A system includes a medical device that regulates delivery of medication to a user, a sleep detection system configured to generate user status data that indicates sleeping status of the user, and configured to communicate the user status data, and at least one controller that controls alerts associated with operation of the medical device. The at least one controller receives the user status data generated by the sleep detection system, determines, from the user status data, that the user is sleeping, activates a sleep mode alerting scheme of the medical device when it determines that the user is sleeping, and, after activating the sleep mode alerting scheme, controls generation and outputting of alerts associated with operation of the medical device in accordance with the sleep mode alerting scheme.

A method of managing and reducing the recall frequency of disturbing dreams comprises monitoring (100; 200; 300) electroencephalography (EEG) activity of a subject, detecting (102; 206; 302) an indicator of a disturbing dream of the subject based on power in a theta or alpha band of the EEG activity of the subject, and providing stimulation (104; 212; 308) to the subject at a frequency lower than the theta band in response to detecting the indicator of the disturbing dream.

A system and method create a framework for personalized sleep hygiene self-experiments to allow users to derive their own discoveries on how the self-experiment has affected their sleep.

A system for obtaining and providing enhanced PAP metrics of a patient's sleep period includes: a pressure support device for use in providing a flow of breathing gas to the patient; a processing unit; and a number of auxiliary devices in wireless communication with the processing unit. Each auxiliary device of the number of auxiliary devices is structured to detect and collect sleep-related data of the patient. The processing unit is programmed to: receive data obtained by a number of sensors of the pressure support device during operation of the pressure support device in providing the flow of breathing gas to the patient; receive supplemental data obtained by the number of auxiliary devices while the pressure support device is not providing the flow of breathing gas to the patient; and determine the enhanced PAP metrics of the sleep period of the patient utilizing the data and the supplemental data.
