Cognitive behavioral therapy for insomnia (CBTi) has been shown to be effective in several previous studies. This systematic, face-to-face therapy has significant benefits for aiding restful sleep.

Research indicates that the same type of therapy can be delivered with a smartphone app.

The study, reported in the Journal of Medical Internet Research, involved more than 150 volunteers with mild insomnia who used the app for 6 to 7 weeks or were placed on a waiting list.

The program, called “Sleep Care,” employs sleep diaries, relaxation methods, and other educational material for improving sleep hygiene.

Volunteers using the app had significant reductions in the severity of their insomnia and improvements in their sleep efficiency.

A follow-up assessment showed sustained benefits three months after the therapy.
