Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sleep device for making human sleep more comfortable.

Conventionally, devices known as sleep-inducing devices, even if they were effective, only had the function of inducing sleep. In other words, it doesn't matter how many hours it lasted or whether you were able to sleep comfortably.

Therefore, in extreme cases, there was a drawback that even if a person fell asleep, he would wake up immediately.

This invention was made in order to eliminate the drawbacks of the conventional devices as described above, and it is a device that can promote comfortable sleep by changing the modulation of the light stimulation presented in accordance with the human's natural sleep rhythm. is intended to provide.

Here, matters forming the basis of this invention will be explained.

In general, sleep is divided into stages depending on the depth of sleep based on brain wave patterns, etc. In order of increasing depth, stages 1, 2, and 2 are divided into stages, with wakefulness as 0, stages
It becomes IV. In addition, there is a type of sleep called REM sleep accompanied by rapid n-ball movements, but to simplify the explanation, it is included in Stage I. There is a pattern (rhythm) in the sleep schedule of healthy people. Figure 1 shows a typical sleep rhythm. According to this, many times my sleep is light (natari (moves towards ■)) and deep (natarari (moves towards ■)).
I can see that it's off. Then, you can see that the cycle becomes progressively longer (and oscillates toward the shallower side), and then occurs.

It is known that this sleep rhythm is very important, as even if you are woken up in the middle of the day, it is relatively easy to wake up if you are woken up in stage I, but it is very bad if you are woken up in stage I or stage I. . Therefore, the reason you can't sleep well is because you can't reach a deep stage, or because you wake up in the middle of stage 2. In fact, people who suffer from insomnia may not be able to sleep at all (this is due to not being able to maintain a normal sleep rhythm, such as not being able to get deep sleep or not being able to sleep for a long time. Therefore, VC for comfortable sleep is only used when falling asleep. Instead, it is necessary to consider the entire sleep rhythm.

On the other hand, what is known as light-driven brain waves refers to the appearance of brain wave components corresponding to the presentation of a light stimulus whose intensity and frequency are modulated. Using this light-driven brain wave, normal brain waves can be drawn into sleep brain waves. In other words, generally speaking, the deeper the sleep, the lower the fundamental frequency of the brain waves, but if the normal brain waves are brought into the sleep brain waves, the sleep stage can also be changed by changing the modulation of yt and stimulation given from the outside. Therefore, this invention focuses on this phenomenon, changes the modulation of optical stimulation in accordance with the normal sleep rhythm, and causes the user's brain waves to show a normal sleep rhythm pattern, thereby promoting comfortable sleep.

An embodiment of the present invention will be described below with reference to the drawings. In FIG. 2, 1 is a user, 2 is an appropriate light source for providing appropriate optical stimulation to the user 1, and 3 is a recorder capable of reproducing the expected sleep rhythm pattern as shown in FIG.
Reference numeral 4 denotes a power source and its controller for modulating the light source 1 in accordance with the output of the recorder 3.

The normal sleep rhythm pattern (first
Alternatively, the target sleep rhythm pattern may be recorded, and the light source 2 and its controller 4 may modulate the light source 2 according to its output. As shown in FIG. 3, the light source 2 is suitably modulated in a sinusoidal manner with a ratio of offset to modulation of 30 to 40% for a certain offset. The intensity is then adjusted to such an extent that the user can perceive changes in the light source with his or her eyes closed. Since it is necessary to raise or lower the fundamental frequency of brain waves in response to changes in sleep stages, the fundamental frequency that modulates the light source 2 is changed. Specifically, the stage ■
4-7Hz when , 2-4H2 when II, I
1-2 Hz for II, 0.5-1 for ■
Let it be Hz. Finally, when awakening the user, the light intensity is extremely increased. Thereby, the user's brain waves can be changed according to each sleep stage, and a comfortable sleep can be obtained.

In the above embodiment, the light source l is shown as something like a lighting fixture that adjusts the light in the entire room, but it is not limited to this, and can be used, for example, by embedding the light source in something like an eye mask (goggles). It may be converted into a text.

Furthermore, a method can also be considered in which the user's brain waves are derived and a doctor or the like directly monitors them to adjust the modulation of optical stimulation.

As described above, according to the present invention, the user's eyes are stimulated with light that is modulated in accordance with the normal sleep rhythm to promote sleep, so that the device is comfortable, safe, and easy to use.
