The present invention relates to sleeping aids, and more particularly, to methods and devices to monitor and manage a user's sleep.
A prevalent and often overlooked cause to many secondary health and social problems is insufficient and/or poor-quality sleep. Estimates show that that 65% of the population has at least a few nights a week suboptimal sleep. Humans require considerable rest each night and if the sleep is broken, brain function, problem-solving, cognitive skills, and reasoning are affected. Other potential consequences of insufficient sleep include short and long-term memory loss, mood changes, a weakened immunity, high blood pressure, weight gain, insulin control, which increases the risk for Type 2 diabetes, heart disease, poor balance, and a lower sex drive. Insufficient and poor-quality sleep will also affect a person's work performance, and likely disrupt their social behavior and social interactions, potentially damaging relationships.
Various methods of improving a person's sleep include physical exercise, breathing exercises and optimizing the user's ambient conditions such as music, light, temperature etc. A variety of monitoring and sleep improvement products have been (or are) on the market, including wearable devices such as wristwatches, armbands, head mounted devices, and non-contact products.
It is an object of the present invention to provide methods and devices for wakeup management for a user to provide improved wake experience
The present invention provides devices, systems, and computer-implemented methods relating to measuring, managing and/or improving sleep. In certain aspects, the wakeup management aspect of the disclosure provides methods for transitioning from sleep to wake depending on the stage or state of sleep one is in at the scheduled time, and if it is determined that at the scheduled time the user is in a deep sleep state, the present system can provide certain transition methods to provide an improved wake experience.
In one aspect, the present invention provides a method of awakening a user, comprising: by using at least one processor, determining the sleep state of the user; and automatically activating one or more selected stimuli to wake up the user in response and according to the determined sleep state of the user. The stimuli can include light, sound, or scent stimuli, for example, audio, visual or video instructions for the user to follow. In some embodiments, determining the sleep state of the user is at least partly based on body movements of the user. In some embodiments, if the user is determined to be in deep sleep state at the scheduled time, one or more stimuli are activated to prompt the user to perform a certain exercise. In some embodiments, if the user is determined to be in deep sleep state at the scheduled time, the system prompts the user to perform a test on his or her alertness or vigilance.
In a further aspect, the present invention provides a system or a monitor device comprising at least one computer processor and an associated memory, where the memory stores instructions which when executed by the at least one processor, cause the system or monitor device to perform the various embodiments of the methods as described herein.

In some embodiments, such auxiliary sensors 25, 26, 27 may be used to detect conditions within the user's bedroom. Processor 12 of monitor 10 may be used to determine if any measured parameter or condition within the bedroom exceeds a predetermined value. In such instance, the user can be informed and corrective measures suggested automatically. For example, if the illumination level in the bedroom is measured by light sensor 26, and the value exceeds a certain predetermined level (as decided by the user or as determined using historical data of the user's bedroom), the present system will inform the user (either by text, email, or through the present software program) of the excessive light condition. In this example, the present system will provide an appropriate suggestion to the user, such as turning off all lights before going to bed, providing a sleep partner with a book-light, if appropriate, using an eye mask, or installing blackout blinds to prevent light from entering the room through windows. If loud sounds are detected in the bedroom at bedtime or during sleep time, the present system may suggest that the user locate the source of the sound and try to eliminate it. If this is not possible, the present system will suggest that the user use ear plugs or an appropriate sound-cancelling device.
In some situations, it may be determined that a user's measured movements while sleeping consistently increase or otherwise change, possibly indicating a level of restlessness, whenever the user's sleep-partner enters the bed. In such instance, the present system would suggest a new bedtime for either the user or the partner so that the user would more likely reach a deep sleep stage when the partner enters the bed and therefore would be less likely to be disturbed. In more extreme cases, separate beds may be required, or at least the use of separate mattresses, box springs and frames, combined together with a common thin mattress topper. This arrangement would allow two bed partners to sleep in a common bed and be close to each other, but at the same time would help mitigate the migration of vibration or strong displacements across the bed.
As mentioned above, based on known factors of a common good sleeping environment, monitor 10, according to the present invention, uses auxiliary sensors 25, 26, and 27 to analyze the environment of the user's bedroom and calculate an “environmental sleepability” rating. According to the invention, the user performs an environment test at an initial installation time (or any other time) and be given not only an environment score, but also suggestions on how to improve the score, i.e., what can be done to the bedroom environment to make the sleeping conditions better for the user. This information is helpful not only for self-assessment of sleeping conditions, but also for property management, property sales, vacation rentals, etc. For example, a landlord can provide a certified environment sleeping score (assuming it is a good score) to prospective renters to show that a particular apartment has a good sleeping environment. Multiple monitors 10 can also be linked within a large house to rate multiple rooms and the information can then be used to map a floor-plan to track inter-room disturbances.
According to guidelines established by the American Academy of Sleep Medicine, sleep is clinically defined by four distinct stages, as determined predominantly by measured degrees of brain activity, muscle activity, and eye movement. The four stages are referred to as stages N1, N2, N3 and REM. Stage N1 and stage N2 is often referred to as Light Sleep, stage N3 as deep sleep (or deep state) and the REM stage as “Dream Sleep.”
Sleep is a very dynamic process, with a sleeper moving between different states throughout the night, usually in a somewhat predictable order, and defining a sleep cycle.
A sleeping person typically experiences several sleep cycles each night, moving from being awake to stages N1, N2, to N3, and then finally to the last REM stage, and then repeating (but starting with stage N2), with some occurrence of becoming awake possible between REM and the following light sleep. Typically the episodes of stage N3 sleep are longer in the beginning of the sleep period, whereas the REM sleep periods tend to be longer at the end of the sleep period.
It is usually not recommended to wake a person who is asleep in N3 sleep. If a person is awakened from stage N3, the body is put under extra physiological and cardiovascular stress. This level of stress is strong enough to potentially trigger cardiac irregularity or arrest in some more vulnerable sleepers. Once awake from a deep sleep, it may take 30-40 minutes for a person's body and mind to be fully functional, alert and aware. If a person is awakened from REM stage, he or she might feel confused for a while, the feelings being influenced by the typically irrational content of dreams, commonly occurring during REM stage. Studies have shown that it is much safer to wake a person who is in light or transitional sleep stage.
The present system using the above-described sleep monitor 10 keeps track of the time that a sleeping user enters each stage of sleep, and also the duration that the user resides in each stage. Monitor 10 can monitor minute movements of the sleeping user to establish the particular sleep stage, based on established sleep-stage body-movement and sound signatures. The present system learns sleep patterns and trends of the user over time and uses the stored sleep history of the user to estimate which state of sleep the user will be in a short time window prior to a planned or scheduled wakeup time (e.g, set by the user via an alarm clock). The user will more likely awake fresh and alert when waking up from a light or transitional sleep stage. According to the invention, if it is determined that the user is in a deep sleep stage near a scheduled wakeup time, the present system (by the monitor device, user's smartphone, or other devices) automatically introduce certain programmed light, auditory, and/or tactile stimuli to encourage the user to exit the deep sleep stage and enter a light sleep stage, and then, from the light sleep stage, slowly be awakened. This slow transition from deep sleep to a light sleep stage before awakening will help the user be awakened safely, fresh and alert.
If a user is awakened during a deep sleep stage, the present invention, according to some embodiments, provides a feature in the present software program wherein a wakeup coach appears on the user's smartphone display and instructs the user to perform well-described physical exercises to help him or her to become more alert. Also, the user's display of his or her smartphone can be controlled by the present system so that the display emits a particular color of light and brightness level. The user is asked to stare at the screen for a predetermined amount of time.
If it is important that a user be fully alert as quickly as possible after awakening, various methods can be used to quickly increase a user's alertness and cognitive skills. A program running on the user's smartphone can be used to test the progress of so-called recovery exercises, including the use of a psychomotor vigilance test, which is the “gold standard” used in the industry to measure alertness or vigilance of a person. In use, once a person awakens, he or she may continue to lie in bed holding their smartphone to take the various tests using the phone. The tests will include simple games that although are simple, require a medium-to-high level of cognitive skill, reaction, and dexterity. The background scene of the game (or just a blank background) can be illuminated at a certain wavelength of light and intensity. By exposing the user to light in the green-blue bandwidth with preferably a high brightness, for example, for a set period of time, the user will become more alert more quickly. According to some embodiments of the invention, an aromatherapy feature can be introduced to the present sleep monitor, wherein a specific and repeatable scent is released for the user to smell in response to any of various actions, functions, or events occurring. For example, the scent of fresh roses may be released into the air from a local supply adjacent the sleeping user, close enough that the user will smell the scent, but not so close as to “suffocate” the user in “roses.” In this example, the rose scent is released around the time that the user typically wakes up so that the user is provided with a pleasant fresh scent as he or she awakens. Another example is to release a lavender scent if the user's sleep score is above average and another scent if it is below average. The user will learn to associate the particular message by just smelling the particular scent, once they awaken. Conventional scent-release technology can be used in combination with the present sleep monitor, or can be a separate device that is connected to either the present software application running on the user's smartphone, or the sleep monitor, by WIFI or Bluetooth or similar.
