Hereinafter, a system for performing a sleep temperature control method for a good night's sleep according to an embodiment of the present invention will be described in detail with reference to FIG. 1.

In the temperature control system 100 for a good night's sleep for performing the sleep temperature control method, after receiving a user 200 setting temperature for the sleeping article from the user 200, after a predetermined time has elapsed, At least one of a control module 110 and a mattress, a blanket, a pillow, a pillow, a sleeping bag, and a control module 110 for controlling the temperature of the sleeping article to the first sleeping temperature and controlling the temperature of the sleeping article to the second sleeping temperature after a predetermined time. Sleeping article 140 including one or more, the sleeping article may further include the wearable device 130 to the body temperature of the user 200.

In this case, the control module 110 may include a timer 120 for checking the temperature control point and setting the time.

For example, the user 200 may set a specific temperature to a desired temperature and input it to the control module 110, and the control module 110 may be configured to fit the temperature input by the user 200. The temperature can be adjusted.

Thereafter, the control module 110 maintains the temperature of the sleeping article 140 corresponding to the temperature input by the user 200 for a preset time (30 minutes), and when the preset time passes, the user 200 inputs it. The temperature of the sleeping article 140 may be controlled from one temperature to two degrees lower.

Thereafter, the user 200 may maintain a low temperature of 2 degrees at the temperature input by 5 to 6 am, and increase the 2 degrees according to the weather time of the user 200.

The external environment, that is, by inducing a change in body temperature according to the temperature change of the sleeping article 140 used by the user 200, when taking a sleep, the time to enter the sleep phase (NREM, deep sleep) as the body temperature drops quickly This can lead to faster sleep.

Increasing the temperature of the sleeping article 140 during the wake-up time of the user 200 is that the body enters the sleep thermal regulation (body temperature automatic control function), the body warms up when the wake-up time, In order to restore the external temperature environment by increasing the temperature of the sleeping article 140 by 2 degrees, the thermal regulation (body temperature automatic adjustment function) can be easily performed to provide a good night's sleep function.

Hereinafter, the correlation between the sleep pattern analysis and the body temperature and the external temperature according to an embodiment of the present invention will be described in detail with reference to FIGS. 2 to 4.

There are two types of human body temperature: internal temperature and skin temperature. Keeping the internal temperature as low as possible during sleep time is closely related to improving the quality of sleep. When it starts. Therefore, the temperature of the sleeping article 140 is raised to 0.5 ℃-1 ℃ higher than the measured body temperature so that the internal body temperature falls quickly when the sleep starts can be helpful to start the sleep quickly after a certain time.

In other words, the more the internal body temperature drops, the longer the NREM sleep and DEEP SLEEP times may result in improved sleep quality.

The correlation coefficient between internal temperature and skin temperature varies depending on the person and the situation, but it is known to move in the same direction from 0.3 to 0.88, and humans have automatic thermoregulation (THERMOREGULATION). Because it reacts more sensitively to external environmental factors, such as the temperature of the sleeping article 140 or room temperature, it is possible to more actively utilize the temperature of the sleeping article 140 during REM sleep.

Referring to Figure 2, you can check the graph for the sleep cycle, when entering the sleep, it can be seen that repeat the NREM sleep state 320 and REM sleep state 310 four to five times.

Referring to the time series analysis graph of the body temperature of FIG. 3, it can be seen that the body temperature is changed to the same pattern as the sleep cycle according to the time change through the time series analysis-based sleep cycle pattern classification.

That is, the sleep cycle can be defined by the change in body temperature over time, and the temperature may gradually decrease and then rise again.

Sleep cycles typically consist of NREM (Light Sleep, Deep Sleep, Very Deep Sleep) and REM stages.

2 to 3 are sleep cycle pattern classifications consisting of NREM sleep state 320 and REM sleep state 310 as a result of analyzing body temperature data over time.

Referring to FIG. 4, when there is a deep sleep, the correlation between the body temperature and the external temperature may be confirmed.

Deep Sleep influence factors can be extracted through PCA analysis (Principal Component Analysis), but Deep Sleep (Sleep Stage) can only appear when the correlation between body temperature and external temperature (sleeping product temperature) is high.

As the optimal temperature range, it can be seen that the deep sleep stage is most expressed in the 18 ° to 20 ° distribution range.

Since the body temperature during the sleep time of the user 200 is a variable that changes with the passage of time, a time series analysis is performed using the measured body temperature as a time series variable, and then it is decomposed into elements of trend and seasonal, so that the sleep cycle and deep sleep You can check the time category.

In addition, through the above-described analysis, the length of the deep sleep time may be longer as the length of the sleep time is longer and the correlation between the internal body temperature and the external temperature (temperature of the sleeping article) is increased.

Hereinafter, a temperature control method for a good night's sleep according to an embodiment of the present invention will be described in detail with reference to FIG. 5.

After receiving the user 200 set temperature for the sleeping article from the user 200, and after a predetermined time has elapsed, the temperature for the sleeping article is controlled as the first sleeping temperature, and after a predetermined time, the sleeping article is The control module for controlling the temperature for the second sleep temperature and may include a sleeping article including at least one or more of mattresses, blankets, pillows, pillows, blankets, sleeping bags.

If it is determined that the height is high, the temperature of the sleeping article may be controlled by the first sleeping temperature. In addition, it is possible to determine when REM sleep starts and control to the 1-1 sleep temperature lower than the first sleep temperature.

In this case, the time point at which REM sleep starts may be derived based on a sleep data pattern derived using past sleep data analysis information. Preferably, the 1-1 sleep temperature may be a temperature of 2 degrees to 2.5 degrees lower than the body temperature of the user 200, and in the case of a healthy general person, a time point at which REM sleep starts may be 1 hour to 1 hour 30 minutes.

In addition, it is possible to grasp when the NREM sleep starts and control the temperature to 1-2 sleep higher than the 1-1 sleep temperature. In this case, the time point at which NREM sleep starts may be derived based on a sleep data pattern derived by using past sleep data analysis information. The first 1-2 sleep temperature may be 1.5 to 2 degrees lower than the body temperature of the user 200.

In addition, at each stage of the sleep cycle repeated three to four times until the preset time, the temperature of the sleeping article 140 may be changed in association with the body temperature in the manner of the additional embodiment of the present invention described above.

The preset time may be preferably from 5 am to 6 am.
