Description

Method, system and device for sleep periodic detection quantification and auxiliary intervention
Technical Field
The invention relates to the field of sleep periodic detection quantification and auxiliary intervention, in particular to a sleep periodic detection quantification and auxiliary intervention method, system and device.
Background
Sleep is the basic physiological requirement and the basic guarantee of life and health of people, and the sleep time accounts for about one third of the life time of people. With the rapid development of social economy, the pressure of work, families, economy, society and the like is continuously increased, the sleeping problems of people are increasingly highlighted and raised, and the risk of diseases related to physiology and psychology is also continuously increased. According to the guidelines of the American society for sleep medicine, sleep stages of humans include a wake period, a non-rapid eye movement sleep period NREM (light sleep 1, light sleep 2, deep sleep), and a rapid eye movement sleep period REM. Good sleep is a cyclic process with good periodicity, with NREM and REM alternating, once a cycle and back and forth, typically for healthy adults each cycle lasts 90-120 minutes and goes through 4-5 cycles per night.
The sleep periodic intensity is different from a sleep circadian rhythm and a sleep time phase staging, the sleep circadian rhythm is widely defined as a 24-hour large-scale behavior rule of multi-day long-term sleep and wake-up, falling asleep and getting up, and the sleep time phase staging is defined as a small-cycle condition that light sleep, deep sleep and rapid eye movement sleep alternate with each other in the one-time sleep process; the sleep cycle strength is a comprehensive measure of the continuous change level of the sleep normal cycle alternating mode in the continuous change of the sleep state of the user and whether the user has the ability to maintain the normal alternating continuous change of the normal sleep mode, and is an indispensable index in the sleep practice evaluation.
At present, no matter in clinical diagnosis and treatment or health management, no clear method exists at home and abroad for accurately evaluating and quantifying the sleep periodicity strength of a user, the sleep quality and the sleep efficiency are difficult to be further scientifically judged and analyzed, and meanwhile, no data is used as a hand grip to realize auxiliary intervention on the sleep periodicity of the user, namely scientific evaluation and auxiliary intervention on the sleep baseline period change strength, the baseline period change trend and the change mode rationality of the sleep state of the user.
For example, patent document CN115525081A discloses an adaptive adjustment system and control method for indoor environment of building, wherein a data processing module is used for integrating posture information of a user and environmental acquisition information of a current period, determining instant photo-thermal comfort feeling of the user, generating a corresponding adjustment instruction, and sending the adjustment instruction to a corresponding execution module. CN114839890A discloses a sleep environment control system, a sleep state detection device, which is used for detecting physiological data of a user, where the physiological data includes body movement data, heart rate data, and respiration data; the analysis module performs the following calculation according to the detection data of the detection module: (1) Judging whether the user gets into bed or not and whether the user has a sleep desire or a sleep trend; (2) judging the sleep cycle; (3) Judging whether the time of falling asleep is consistent with the rhythm improvement plan; (4) Judging whether the environmental data is consistent with the preset environmental data; (5) Judging the conformity of the sleep, awakening and rhythm of the user in the month, week and day with the big data standard plan; but does not teach how to calculate the sleep period. It is also seen that the prior art only proposes a fuzzy assumption, and how to calculate the sleep cycle, how to scientifically measure the influence of environmental factors on the sleep cycle, how to accurately control environmental changes, and the like all have blind areas.
Therefore, the prior art needs to be improved to accurately quantify the sleep cycle variation and efficiently improve the sleep experience of the user.
