Background
Sleep is the basic guarantee of human life processes such as physical energy and energy recovery, body growth and restoration, negative emotion elimination and the like. The difficulty in falling asleep for a long time, the easy arousal and multi-arousal of sleep, the poor sleep maintenance capability or sustainability, the poor sleep quality, especially the excessive sleep arousal or sleep interruption severely limit the work ability, the object execution and the emotional expression of people in the daytime, seriously affect the normal learning, work and life of people, and even lead to serious nervous system diseases and psychologic diseases and the rehabilitation process of related diseases.
The sleep sustainability or sustainability is distinguished from the sleep circadian rhythm, which is broadly defined as a 24-hour large-scale behavior law of multi-day long-term sleep and wake-up, sleep-in and wake-up, and the sleep phase staging, which is defined as a small-cycle condition in which shallow sleep, deep sleep and rapid eye movement sleep alternate with each other in one-time sleep; the sleep sustainability or sustainability is a comprehensive measure of the level of sleep interruption and the level of continuous change of the normal sleep mode in the continuous change of the sleep state of the user, and whether the user has the ability to maintain the normal sleep mode without continuous change of arousals, and is an indispensable index in the evaluation of sleep practice.
However, in the clinical diagnosis and treatment of sleep medicine and the health management of sleep behaviors, only the sleep circadian rhythm and the sleep phase stage are primarily analyzed and evaluated at home and abroad, the sleep interruption level, the normal continuous change level of sleep and the sleep maintenance capability of a user in the continuous change of the sleep state are not analyzed, evaluated and intervened, namely a scientific quantitative analysis method and an auxiliary intervention method for the sleep sustainability are lacked, data, evidence and plan guidance cannot be provided for the sleep health management or the sleep medicine clinic, and the sleep interruption event is identified and reduced, so that the sleep sustainability, the continuity and the sleep experience of the user are ensured.
For example, in the prior art, patent document CN104434068A discloses that the sleep stages of a human body are monitored by using body temperature and heart rate information, and the sleep quality of the human body is judged, but the decomposition of different sleep stages is discrete, the continuity is lacked, and the quantization error is large, so that the fine granularity of subsequent control is not high; only comprehensive analysis is mentioned for the environmental impact, but no specific embodiment is given. 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 user and environmental acquisition information of the same period, determining instant photo-thermal comfort feeling of user, generating corresponding adjustment instruction, and sending the adjustment instruction to corresponding execution module. It is also seen that the prior art only proposes a fuzzy assumption, how to use physiological detection information in the sleep regulation process and how to scientifically and accurately control all the physiological detection information in the sleep regulation process have a blind zone, and no proposal is proposed for completing subsequent regulation by utilizing the influence of a sleep sustainability index and an observation environment on the index.
Thus, the prior art remains to be improved to accurately quantify sleep sustainability, improving the user sleep experience.
