This year, the topic of "sleep" has been on the hot search, which shows that people are paying more attention to the health of sleep. With the advancement of science and technology, there are more and more types and quantities of sleep aids on the market, in which case how can we choose a product that really has the effect of helping us sleep and is suitable for us?
As a core member of the Sleep Research Institute, we have a long way to go! So you plan to find a number of popular sleep products on the Internet, for the majority of users to evaluate, these monthly sales of more than 10,000 sleep products is a miracle drug or IQ tax!
01 Unboxing - Experience
You have found a popular sleep egg in a treasure, the details page describes the product is exported to 26 foreign countries, improve the insomnia of 3205601 individuals, the price of 118 yuan, monthly sales of 1W +, the comments also have 1289, you feel a little powerful (wow!), so order + evaluation arrangement. , so the order + evaluation arrangement!
3 days later, YouYu received the courier, the strange thing is, obviously ordered a sleep egg, open when the box is the palm of the hand intelligent soothing instrument. It was puzzling, but it doesn't matter, as long as it helps you sleep, whatever works!

"Packaging and gifts": minimalist style product packaging, simple and clear instructions, too practical for handicapped parties like Youmons, but also additional gifts of earplugs and sleep eye masks, the feeling is still very thoughtful.

"Product Form and Function": This product, named Smart Palm Soothing Instrument, the product as a whole is white and silver metal-based, simple and generous. By pressing the M button on the surface, you can switch between excitement/sleep aid mode; the plate on the top of the product can be adjusted in power by twisting it from right to left; the two circles of round metal on the back are positive and negative sensing circles.
According to the detail page, this product can calm and relieve anxiety, and has the effect of sleep aid. After careful research, we found that the principle of this product is to "promote muscle contraction through microcurrent": the electric current touches the palm through the two round metal circles, forming a circuit, so that when you hold your hand, you can feel an electric current, and thus achieve body relaxation.
The product's efficacy is divided into two modes: "Sleeping mode" has a smaller current; "Excitement mode" has a relatively larger current, which feels like the electrotherapy treatment that YouYu went to the hospital for last month's lumbar muscle strain.

The manual describes holding the device in your hand for 20 minutes before going to bed, once a day in the morning, once in the evening, and once in the evening.
You said the trial of three nights, hand numbness and a little excited, froze. But the most unacceptable is the switch setting accompanied by a green flashing light, for YouYu such night can not accept the light of the insomnia patients is really too difficult!
02 Does brainwave activity change before and after product use?
The detail page says that the brainwave will change before and after using this product. For this reason, YouYu specially asked a teacher who is more authoritative in the field of brain technology - Dr. Rain.
Dr. Rain said, our brain consists of hundreds of millions of active brain nerves, the axon length of the total **** there are 170,000 kilometers, the brain nerves interact with each other to produce electrical signals, and the overall reflection of the electrical signals is the so-called brain waves, different brain waves correspond to different brain states.
Brain waves are mainly divided into four types:
Beta wave (Beta wave): the brain waves of people in a state of tension, 14-30Hz;
Alpha wave (Alpha wave): the brain waves of relaxation and meditation, 9-13Hz;
Theta wave (Theta wave): the brain waves of half-sleep/deep meditation, 4-8Hz;
Theta wave (Theta wave): the brain waves of half-sleep/deep meditation, 4-8Hz;
Theta wave (Theta wave): the brain waves of half-sleep, 4-8Hz;
Theta wave (Theta wave): the brain waves of half-sleep, 4-8Hz. 8Hz;
Delta waves: brain waves in deep sleep, 1-3Hz.

According to the AASM (American Academy of Sleep Medicine) standards for EEG interpretation. People will produce more beta waves in the state of tension, when gradually relaxing, more alpha waves will be produced, if they gradually enter light sleep, theta waves will be presented, and when they enter the state of deep sleep, more delta waves will be produced.
This product is described as having more δ waves before use, which means more deep sleep, and the person is in a very quiet state, and more α waves after use, which means relative relaxation. According to this logic, that is, after using the sleep egg people's state is gradually excited. No wonder Yuuu was getting more and more aroused when she used it before bed.
If the original article on the details page is understood, it is not in line with general medical facts. If it really helps sleep, there should be a gradual decrease in beta and alpha waves and a gradual increase in theta and delta waves.
03 Does the product really work?
In order to scientifically confirm whether the Sleep Egg is a sleep aid or not, with the help of Dr. Yu, YouYu decided to use the gold standard of sleep monitoring, which is polysomnography.
Polysomnography is the most commonly used means of sleep monitoring, and is the most important test for diagnosing snoring, as well as the internationally recognized gold standard for diagnosing sleep apnea and hypoventilation syndrome.
Nevertheless, polysomnography needs to be monitored in hospitals with large instruments, and it is impossible to monitor at home, and the operation is too troublesome.
So YouYou used the YouMonitor Sleep Recorder, which is shown on the FDA as having received a national Class II medical device license.

Can record, store, and analyze our sleep EEG, blood oxygen saturation, pulse rate, body position, body movement physiological parameters, but also can analyze and diagnose the sleep disorder related diseases. You can enjoy medical grade sleep monitoring at home with easy operation.

As shown in the above figure, it can be shown that the night before using the Sleep Egg, it took about 10 minutes to enter into sleep, 15 minutes to fall into light sleep, and 20 minutes to enter into deep sleep.

Figure on the left, shows YuYu holding this sleep product in his hand and turning on the sleep aid mode. The whole brain wave is in a smooth state, and there is no obvious change in the EEG signal before and after.
Figure from Umocean | Sleep monitoring when YuYu used the product for the second time
As shown in the figure above, YuYu was in the middle of wakefulness and light sleep repeatedly for 2 hours on the night of use, and the whole sleep structure was disturbed. Perhaps because of the first time to use this sleep aid products caused by the current caused by the arm numbness is not accustomed to, and the light has been flashing in the dark. It was a very difficult sleep for Yuyu!

The third time I experienced it, I hid the product under the covers so I couldn't see the flashing lights, but my hands were still a little excited. From the sleep monitoring display, it also took about 15 minutes to get to sleep.
04 Is it actually a sleep IQ tax?
From the results of the EEG monitoring above, this product is not obvious enough to help you sleep (probably because you measured less). However, this intelligent palm restorative device has the effect of "helping you sleep", and its microcurrent can promote muscle contraction to achieve the effect of relief, which is certain.
But for those who really have sleep problems, you are advised to go to the hospital to do a sleep EEG monitoring, to grasp their own sleep structure, sleep staging, body position, body movement, snoring, oxygen saturation and other related sleep conditions, and then go to do targeted sleep optimization.
Different people have different feelings, anyway, this product is not suitable for YouYou, is a sleep IQ tax, or a night sleep in front of the green light of the "IQ tax"!
