Light, Sleep and Rhythm Planner: A Free Winter Light and Sleep Routine Worksheet
Depression · CBT · Practice-informed
A planner for the light, sleep and rhythm part of CBT for seasonal affective disorder. It builds a morning light plan, a gentle clock-change bridge and a weekly tracker. Bright light has meta-analytic support in seasonal affective disorder, although a 2024 network meta-analysis rates the quality of that evidence as low. Using it before an episode has not been directly trialled.
Underlying mechanism: Morning Light, Clock-Change Bridge and Sleep-Rhythm Tracker for Seasonal Low Mood
What it helps with
- Making morning daylight and a steady wake time a concrete plan before the clocks go back.
- Easing the clock change by moving wake time and bedtime by about 15 minutes a day, then holding a consistent wake time.
- Making wind-down routines specific, so they are repeated and not just intended.
- Showing client and clinician the real pattern of sleep, light, energy and mood in a weekly tracker.
How clinicians use it
- Review the evidence honestly with the client, then build the light plan around what they will actually do.
- Fill in the four-day bridge in the room, or use the Winter Watch micro-tool to work out the times.
- Ask the client to track for a week or two and review the pattern at the next session.
Clinical Implementation Guide
- Ask about elevated mood and medical cautions before any light box talk.
- Fill in the bridge so the first step lands on the day your client can start it.
- Review the tracker at the next session and ask what the client notices.
What the worksheet looks like
| Part of the sheet | What the client does | Notes |
|---|---|---|
| Morning light plan | Ticks and times outdoor light and bright-window options | Daylight is often far brighter than indoor light |
| Light box note | Reads the cautions and checks with the GP | Standard device rated at 10,000 lux, used in the morning |
| Clock-change bridge | Plans four days of about 15 minute steps | Practice-based, not trialled |
| Winding down | Dims lights, limits screens and repeats a calming routine | Optional slow breathing from W3 |
| Weekly tracker | Records wake, outdoors, bedtime, energy and mood | Look for patterns, not perfection |
Clinical cautions
Ask about past elevated, irritable or unusually energised periods before any light advice, because light can be unsuitable in bipolar spectrum presentations. Light boxes need a GP or pharmacist check, especially with eye conditions, light-sensitising medication or migraine. Stop and seek advice with headache, eye strain, agitation or unusually elevated mood. The clock-change bridge is a practice-based approach and has not been trialled. Sleeping far more than usual or lying awake for hours most nights needs a conversation with the GP. This tool is not a substitute for individual face-to-face therapy or for emergency crisis support.
