Intervention: Sueña component 1: Sleep Hygiene Promotion
Description: The nursery staff will be instructed to promote sleep hygiene. Nurse technicians will: inform patients of the efforts to ensure a healthy sleep environment, verify the minimization of light and noise after 23:00 PM, favour natural light after 07:00 AM, and foment patient's activities and participation in group therapy. Nurses will: reduce sleep interruptions to a minimum, to only perform actions (i.e. blood testing, clinical controls, medicine administration) deemed strictly necessary between 23:00 PM and 07:00 AM. A list of commonly used medications with their pharmacodynamic and pharmacokinetic properties tailored by a pharmaceutical chemist will be provided, to ensure optimal medication administration while protecting the guaranteed sleep hours, to be coordinated with the treating physician.
