How it shows up

Low mood can last hours, days, or longer, often without a clear trigger: gray weeks, tired seasons, stretches when everything feels like effort. People may notice flatness, low energy, and less interest in usual pleasures. Causes can include sleep, stress, health, circumstances, or nothing obvious. It is common and not in itself a diagnosis; what sets it apart is that it lingers and spreads without needing one clear reason.

How it differs from Sadness

Sadness usually has an object, a loss or an unmet want; low mood is a flatter, lower-energy state that may not be about anything in particular.

Notice

Notice whether low mood shifts with sleep, light, company, or time of day.

Where it is felt

Felt most in the chest, shoulders and head.
