2. How is depression different from everyday sadness? Sadness is a natural, temporary emotion triggered by specific events. Depression, on the other hand, is a medical condition characterized by persistent low mood, loss of interest in once‑enjoyed activities, changes in appetite or sleep, and feelings of hopelessness that last for at least two weeks. Unlike ordinary sadness, depression impairs daily functioning—making it hard to work, study, or maintain relationships. Evidence‑based treatments include psychotherapy, structured self‑care routines, and professional monitoring. If you suspect you or a loved one may be experiencing depression, consult a qualified mental‑health specialist promptly.
