This study will test whether a personalized mobile application that provides temperature-related health risk warnings and protective recommendations can reduce acute exacerbations in people with chronic obstructive pulmonary disease (COPD). Researchers will compare participants who receive the mobile application in addition to usual care with those who receive usual care alone. The main question is whether the mobile application reduces the number of COPD acute exacerbation events over 12 months. The study will also evaluate secondary outcomes including quality of life, functional capacity, symptoms, psychological status, physiological and biochemical indicators, environmental temperature risk perception, and participants' use of the mobile application.
