Ion Sleeper

Ion Sleeper

Developed to support good sleep

It is a negative ion generator.

Negative ions speed up the metabolism of the brain hormone serotonin, which improves the quality of sleep, and activate the parasympathetic nervous system, increasing the relaxation effect and leading to deep sleep.

Negative ion generation rate: 340,000 ions/cm3

The Ion Sleeper constantly generates 340,000 negative ions per cm3, which is about 35 times the amount of negative ions produced by a waterfall, and has been certified as Class 5 by the Japan Functional Ion Association.

Patented power metal!

The back of the Ion Sleeper is equipped with a patented power metal, which allows negative ions to be absorbed into the body more efficiently. (Patent No. 5062706)

Safe without electromagnetic waves!

Ion Sleeper does not emit electromagnetic waves that are said to disturb sleep, so it is safe to place it next to your pillow.

Comes with a magnet for peace of mind!

The Ion Sleeper can be secured in place with a magnet and plate on the back of the unit, so you don't have to worry about it tipping over while you sleep.

Lightweight and compact

The Ion Sleeper weighs just 28g and fits in your hand, making it easy to carry around.

It can be carried around in the included drawstring bag.

Test results using Ion Sleeper

Please install the device so that the emission hole faces people and exposes them to negative ions.
By attaching it directly to your pillow or sheets, negative ions can penetrate more easily.
Simply switch it on and place it next to your pillow to fall asleep while bathing in negative ions.

It can also be used to have negative ions rain down from high above your head.
*Negative ions can also be released by air purifiers, air conditioners, and natural wind, so we generally recommend using it next to your pillow.
