What the trial is, and whether it could suit you
Mental disorders have become a major contributor to the global burden of non-communicable diseases, with disability-adjusted life years (DALYs) attributable to these conditions continuing to rise. Although evidence suggests that environmental factors may account for up to 40% of the attributable risk for mental disorders such as major depressive disorder, anxiety disorders, and alcohol use disorder, the underlying mechanisms remain unclear, particularly regarding how dynamic environmental stress influences disease onset, progression, and relapse. Traditional research has primarily focused on individual-level psychosocial factors, including socioeconomic status and life events, while lacking real-time, multidimensional assessments of objective urban environmental stressors such as air pollution, noise exposure, and reduced green space.

3. Normal intelligence and ability to use a smartphone running the Android operating system;
4. Willingness to wear a wristband equipped with physiological monitoring functions (such as heart rate and electrodermal activity), download the study application, and upload data during the study period;
5. Participants with depression or generalized anxiety disorder who are taking medication must be on a single stable dose of a selective serotonin reuptake inhibitor (SSRI), specifically citalopram or escitalopram, and this medication regimen must have been maintained for at least 5 days. Participants with alcohol use disorder who are taking medication have no restriction on the type of drug, but the medication regimen should also have been maintained for at least 5 days. At baseline assessment, patients with depression or anxiety disorders should have a Hamilton Depression Rating Scale (HAMD-17) score \>7 or a Hamilton Anxiety Rating Scale (HAMA-14) score \>7.;
6. Voluntary participation in this study and signing of informed consent;
7. For patients with alcohol use disorder (AUD): AUD patients must have successfully completed alcohol withdrawal, confirmed by clinical standards or relevant healthcare professionals.

4. Voluntary participation in this study and signing of informed consent.
Exclusion Criteria:

3. Skin infection or severe skin damage on the wrist or upper limbs that may affect the normal use of monitoring devices;
4. Recent use (within 30 days) of medications that may interfere with drug metabolism, such as strong CYP450 inhibitors/inducers;
5. Severe physical diseases (such as brain tumors or injuries) or special conditions (such as current pregnancy or lactation) that may affect the study protocol;
6. HAMD-17 item 3 (suicide) \>3 points (severe suicidal behavior);
Exclusion Criteria for Healthy Control Group
1. Currently using benzodiazepines or opioid medications;
2. Currently receiving any form of brain stimulation therapy (including transcranial magnetic stimulation (TMS), electroconvulsive therapy (ECT), or other similar treatments);
3. Skin infection or severe skin damage on the wrist or upper limbs that may affect the normal use of monitoring devices;
4. Recent use (within 30 days) of medications that may interfere with drug metabolism, such as strong CYP450 inhibitors/inducers, or not reaching steady-state drug concentration before the study;
5. Severe physical diseases (such as brain tumors or injuries) or special conditions (such as current pregnancy or lactation) that may affect the study protocol.
