Insomnia (Self-reported, Non-diagnosed)

The goal of this study is to evaluate the feasibility and the effect of self-acupressure on improving insomnia among the elderly with hypertension who reported insomnia (using the Insomnia Severity Index questionnaire) The main questions it aims to answer are: * Is the proposed intervention feasible to deliver to the target population in terms of recruitment, retention, adherence, and completion of outcome assessments? * Does self-acupressure improve insomnia among the elderly with hypertension? Researchers will compare participants in the self-acupressure group (practice acupressure at home for 28 days) and the enhanced standard care group to see the effectiveness of acupressure in improving insomnia for hypertensive elderly individuals. Participants in the self-acupressure group will be instructed how to locate and perform acupressure, then they will be asked to practice acupressure at home for 28 days (once a day). Participants in the enhanced standard care group will receive training on how to apply sleep hygiene rules and will be asked to follow sleep hygiene rules for 28 days.
