The number, drawn
Why it matters
- In general sleep guidance, morning daylight helps set the body clock.
- Trouble falling asleep is more common in adults with ADHD, so this is a reasonable low-cost habit to try.
- Ordinary outdoor light is not the same as prescribed bright-light therapy, and a reliable ADHD symptom benefit has not been established.
How to do it
- Find a safe chance to go outside in the morning.
- Start with however much daylight fits comfortably into your morning.
- If your sleep keeps running late, talk to a clinician instead of buying a treatment lamp on your own.
This means normal daylight, not looking at the sun or using a light therapy device.
Putting it into practice
In real life
- Sit outside briefly after getting up if that is accessible.
- Take an ordinary morning walk when weather and mobility allow.
Watch out for
- Common mistakeA light box is a separate treatment. Ask a clinician before using one for a sleep disorder.
- Common mistakeBad weather doesn't have to break a streak. Use the next safe chance.
