Objectives: The study purpose was to conduct a four-week randomized double-blind placebo-controlled crossover trial on adults with insomnia symptoms to examine the effectiveness of Natural Frequency Technology(®) (NFT), found in Philip Stein Sleep Bracelets, on sleep quality, anxiety/stress levels, and mood.

Methods: Adults (N = 44, M age = 41.9 years) were randomized to the Placebo Bracelet (PB) or NFT Sleep Bracelet (SB) for two weeks and then the alternative bracelet for two weeks. Self-reported mood, anxiety/stress, and sleep quality were completed at Day 0 (PRE) and following each condition; POST PB and POST SB).

Results: When the participants wore the SB, compared to the PB, they had improved sleep quality (i.e., Pittsburgh Sleep Quality Index), anxiety/perceived stress, and mood, p’s < .05.

Discussion: The SB may be simple, noninvasive, and non-pharmacological intervention to improve sleep quality and daytime mood.
