Sleep is an essential physiological process that is influenced not only by mental and behavioral functions, but also by the surrounding sensory conditions. Emerging but mixed evidence shows that sensory-based interventions, such as light, sound, and temperature, can aid sleep for some individuals, though effects vary by population and outcome. Light therapy influences circadian rhythms and has clinical applications for sleep-wake disorders. Auditory interventions including white, pink, and brown noises, autonomous sensory meridian response, music, and natural sounds can mask environmental disruption, though they are most effective when tailored to the individuals’ sensory profiles. Ambient temperature control particularly in populations facing night sweats or menopause also influences the initiation and maintenance of sleep. However, how these modalities can be integrated together to increase adherence and success in individual patients have not been extensively reported. In this narrative review, we highlight recent research on light therapy, auditory intervention, and thermal regulation in improving sleep health, and suggest integration of these modalities to supplement Cognitive Behavioral Therapy for Insomnia. While evidence quality varies considerably, integrating sensory approaches may complement established behavioral therapies and broaden accessible, non-pharmacological options for improving sleep health. Continued research is needed to determine optimal combinations, timing, and individual responsiveness.
