About this trial
Insomnia is a prevalent sleep disorder associated with substantial negative health consequences, including fatigue, irritability, and impaired daytime functioning. Although effective pharmacological and psychological treatments exist, fewer than half of individuals with insomnia seek professional treatment, highlighting the need for accessible and acceptable non-pharmacological interventions. Sleep hygiene education (SHE) has the potential to address this gap due to its simplicity, low cost, and ease of self-administration. However, previous studies have often underestimated the efficacy of SHE by using it as a passive control condition rather than an active, structured intervention. To address this limitation, the proposed pilot study aims to evaluate the feasibility and effectiveness of a theory-based, structured SHE program integrated with behavior change techniques.
