With the intensifying aging population, the demand for caregiving has grown significantly, while the number of caregiving professionals has not kept pace. This study aims to assess the effectiveness of Mood Plants, a customized flower delivery service, in alleviating stress among caregivers. Over a three-month period, 30 caregivers from a care facility in Henan Province, China, participated in the study. Their real-time mood, burnout levels, and attitudes towards Mood Plants were evaluated using the Visual Analogue Scale (VAS), Maslach Burnout Inventory (MBI), and semi-structured interviews. The results demonstrated significant improvements in caregivers’ mood, reductions in burnout, and positive shifts in attitudes towards the intervention. By providing a personalized flower delivery service, Mood Plants effectively enhanced the psychological well-being of caregivers, offering a simple yet impactful solution to address the mental and emotional challenges faced by those in the caregiving profession. The study highlights the potential of Mood Plants as a valuable tool for reducing stress and promoting mental health among caregivers in demanding work environments. These findings encourage further exploration and broader implementation of Mood Plants to support the well-being of healthcare professionals.
