What should you know about winter depression?

Some people notice a recurring change in mood, energy, sleep, appetite, motivation or concentration as the seasons change. Reduced daylight, changes in routine, less outdoor activity and social isolation can all affect how a person feels. Depression can present with persistent sadness, loss of interest, guilt, slowed thinking, irritability, fatigue, or thoughts of self-harm. A seasonal pattern is still worth taking seriously, particularly when it affects work, relationships, self-care, or sleep.

Poor sleep can both accompany low mood and make coping more difficult. A clinician can also consider physical health problems, medicines, anxiety and other factors that may be contributing.

Keep a regular wake time, plan daylight exposure and gentle activity into your day, and stay connected with people you trust. Break tasks into manageable pieces when motivation is low. Avoid relying on alcohol or non-prescribed substances to change mood or sleep, as they can worsen sleep and emotional symptoms.

Make an appointment with a GP or mental health professional if low mood persists, returns with the seasons, or limits daily life. They can discuss talking therapies, sleep support, medicine options when appropriate, and whether a structured light-based treatment is suitable for you.

Seek urgent help now if you have thoughts of harming yourself or someone else, feel unable to keep yourself safe, or are hearing or seeing things that others do not. Contact local emergency services, go to the nearest emergency department, or ask a trusted person to stay with you while you get help. Prompt support is also appropriate when severe insomnia, agitation, or inability to manage basic needs is developing.

Ask whether your symptoms suggest depression with a seasonal pattern, what treatments fit your situation, and how to make a safety plan if your mood worsens. Share when symptoms begin, how long they last, sleep changes, daytime sleepiness, and any family history of mood conditions.
