Scientific evidence supports the use of the sleep app Calm for decreasing daytime sleepiness and fatigue and for reducing somatic and cognitive pre-sleep arousal. The use of Calm is also empirically substantiated as a means of improving sleep quality. Consequently, the Calm app may be an effective treatment modality for adults presenting with sleep disturbance. Moreover, the app is relatively affordable further suggesting that the data may have broad applicability and implication for community dissemination.
