Disease description:

In recent months, I have noticed that I feel well during the daytime and am able to work and socialize normally. However, once night falls, I begin to feel down and depressed, even experiencing a闷痛 (stuffiness and pain) in my chest. This condition has persisted for several weeks, causing me considerable distress and concern that I might have a certain illness.

Nocturnal depression, also known as "sundown anxiety" or "evening mood lows," is a common manifestation of emotional disorders. Patients may feel unusually sad, helpless, or anxious at night, often accompanied by physical discomforts such as chest tightness and palpitations. This condition may be related to individual circadian rhythms, hormonal changes, life stress, or mental health issues. The symptom of chest tightness could result from either physiological responses triggered by depressive emotions or underlying heart problems.

It is recommended to seek help from a professional counselor to explore and address psychological issues through talk therapy and to learn effective strategies for managing nocturnal depression. Additionally, maintaining a regular sleep-wake schedule, avoiding caffeine and heavy meals in the evening, and creating a sleep-conducive environment, such as keeping the bedroom quiet and comfortable, are advised.
