Depression and exhaustion: what to know

Depression-related exhaustion is more than ordinary tiredness. You may wake unrefreshed, move slowly, struggle to begin simple activities, or need to rest after small efforts. Low mood and reduced interest can make each task feel heavier, while poor sleep may further reduce daytime energy.

Exhaustion has many possible contributors, including anaemia, thyroid problems, infection, medication effects, and disrupted sleep. [Fatigue](/symptoms/fatigue/) and [Daytime Sleepiness](/symptoms/daytime-sleepiness/) describe related experiences, but a clinician can help distinguish them.

Book a clinical assessment if exhaustion is new, persistent, worsening, or limiting daily life. Mention mood changes, sleep pattern, appetite, medicines, alcohol or drug use, and any physical symptoms. A clinician may consider physical causes as well as depression and agree a treatment plan.

Use a small, repeatable routine: get up at a consistent time, eat regularly, drink water, take brief gentle walks if able, and divide chores into manageable parts. Accept practical help from someone you trust. Treatment for depression may include talking therapy, medication, or both.

Get urgent help if you have thoughts of suicide or self-harm, feel unable to stay safe, become confused, faint, have severe breathing trouble, or cannot manage basic needs. Use local emergency services or the nearest emergency department and involve a trusted person. Seek prompt review if exhaustion suddenly becomes much worse.
