what are the disadvantages of head-mounted and hand-held sleeping devices?

First of all, the disadvantages of the head-mounted sleeping instrument are obvious. As mentioned above, the conduction medium in the head is much more complicated than the earlobe. Although it is close to the brain, it is difficult to stimulate the central nervous system of the brain with specially designed micro-current.

Secondly, most head-mounted sleeping devices on the market do not have CES therapy, and they are only used for massage by electric current stimulation on their heads, and the cost is less than 1 yuan. Therefore, its sleep aid effect can be said to be negligible.

In addition, the hand-held sleeping instrument is also a kind of sleeping aid product that has attracted high attention recently. Although some of these products have CES therapy, its action site is only on the hand, which is far from the thalamus, so it is difficult for micro-current to stimulate the action point, which greatly reduces its sleeping aid effect.
