What should you know about spring depression?

A seasonal change does not make persistent sadness, loss of interest, or hopelessness something to dismiss. A person may also notice fatigue, irritability, anxiety, daytime sleepiness, difficulty sleeping, or trouble concentrating. Changes in daylight, routine, sleep timing, allergies, stress, and an existing depressive illness can overlap, so the pattern and its effect on functioning matter more than the season alone.

Keep track of mood, sleep, energy, appetite, and activities for several days. This can help a clinician distinguish a temporary adjustment from depression or another problem such as insomnia.

Keep a regular sleep and wake schedule, eat routinely, and choose gentle movement that fits your health. Morning daylight and time outdoors may support a steadier routine, while reducing alcohol and protecting quiet time can help sleep and mood. Tell someone you trust what you have noticed. Arrange a primary-care appointment if symptoms persist, recur each spring, or interfere with work, study, relationships, or self-care; treatment may include talking therapy, medication, or both after assessment.

Seek urgent help now if you may harm yourself, cannot stay safe, feel unable to care for basic needs, or develop severe confusion or unusual agitation. Contact local emergency services or a crisis service, and stay with a trusted person if possible. Prompt medical review is also appropriate when sleep loss, anxiety, or low mood is rapidly worsening.

Ask whether your symptoms fit depression, how sleep or medicines may contribute, which treatment options suit you, and what plan to use if the pattern returns next spring.
