You might find that it becomes easier to fall asleep when you are near
the forest or beach, or when it rains because of negative air ions (NAI).
NAI enables you to obtain rich slow wave sleep (deep sleep).

Scientific researches find that air humans breathe contains air ions,
which are essential to life and body functions. The imbalance between
positive ions and negative ions will have a profound impact on your
physical and mental health.

Surplus of positive ions or a deficiency of negative ions will induce the over production of neurotransmitter serotonin, which is responsible for insomnia and sleep disorders.

Negative air ions can regulate the balance of serotonin levels and
increase the biochemical reaction of melatonin, a main ingredient to help
people falling asleep quickly and prolonging the slow wave sleep time. Similar to the scenario staying next to forests and beaches, you are easily falling asleep and getting plenty slow wave sleep.

Nutri Air Solution Inc. has invented the NAI chip and developed the
world's first made-in Canada disruptive black technology - NAS slow wave
sleep machine after six year R&D and millions dollar investment. NAI filed

effect can convert surplus serotonin in your body and brain into a harmless
chemical substance, such regulates the serotonin levels. NAI increases the
biochemical synthesis reaction of melatonin (natural sleep hormone)
produced by the pineal gland in the brain, activates sleep biological nerves,
synchronizes the sleep rhythm clock, shortens the slow wave sleep latency,
and prolongs slow wave sleep time for a high quality deep sleep
