Description

A kind of sleep quality monitoring method and monitoring system

Technical field

The present invention relates to a kind of sleep quality monitoring method and monitoring system.

Background technology

The sleep of human body is divided into shallow sleep stage and deep sleep stages, penetration depth Sleep stages from the shallow stage of sleeping, and then gradually shoal, enter rem to sleep namely rapid-eye-movement sleep (REM sleep), and maintain a period of time, so just complete a sleep cycle, a night about has 4 ~ 5 sleep cycles repeatedly to replace in sleep.The quality of sleep quality is not the length depending on the length of one's sleep completely, even if the length of one's sleep is sufficient, but interrupted deep sleep stages, the longterm memory recovery that this stage carries out and important physiological metabolism process are by disturbed, long-term appearance is this to interrupt or wakes up being not suitable for the sleep of stage by people, will greatly affect physical and mental health and the brain memory function of people.If people just wakes up in the time of people's setting by alarm clock, the deep sleep stages be at that time may be interrupted, the longterm memory that this stage carries out can be had a strong impact on and recover and important physiological metabolism process, even if people is waken up, also be difficult to recovery waking state.So the today of day by day accelerating in rhythm of life, " waking up naturally " has become the extravagant hope of a lot of modern.

According to circadian Basic of Biology, find that Short Term Component sleep deprivation can cause endocrine and metabolic disorders, the biorhythm factor that prompting causes sleep to reduce may have important pathology sense.So people can be waken up the physical and mental health by directly having influence on people naturally in the suitable time.

Existing sleep monitor equipment comprises two kinds in the market, and a kind of based on acceleration transducer and physical button, another kind is the sleep monitor equipment based on brain wave.The shortcoming of the first sleep monitor is that the unification of its function causes the inaccurate of sleep monitor.Physical motion state merely based on user is difficult to differentiate different Sleep stages, sleeps from shallow, to sound sleep, then to the rapid-eye-movement sleep (REM sleep) stage.In addition, when equipment is placed in static environment, such as equipment is positioned over desktop, can is deep sleep stages by misjudgement.Use physical button to start and exit that sleep pattern more can bring user to use constant.The second sleep monitor equipment brings the sleep monitor precision improved than the first equipment, but requires that the necessary wearable device of user is peripheral in brain, and this makes ease of use be subject to considerable restraint.

Above carried sleep monitor equipment only possesses the alarm clock function based on absolute time usually, but cannot wake up according to user's sleep quality.Such as, sound sleep arousal function after 30 minutes.
