Questions

Before you enroll.

What do I actually have to do, and how long does it run?

Pick the circadian habits closest to what you already do — morning light, a steady wake time, a dark evening — and spend about a minute a day logging sleep, energy, and mood. Most protocols run 14 to 30 days. Report honestly, and let the numbers build against your own starting point.

Do I need special lights, glasses, or a device?

No. Morning sunlight and ordinary evening dimming are enough. If you already own light-therapy gear or a wearable, you're welcome to fold it in, but the study runs fine without any of it.

Is this safe, and what if I have a sleep or mood condition?

This study is for educational and informational purposes only. It does not provide medical advice, diagnosis, or treatment — talk to your clinician, especially if you have a diagnosed sleep disorder, bipolar disorder, or take related medication. You can withdraw at any time.

What if my schedule is irregular, or I work shifts?

You can still take part — you report what your days actually look like. Shift and irregular schedules are exactly the kind of real-world pattern the study is built to read, measured against your own baseline.

What will I see at the end, and who can see my data?

You see your own result first — your sleep, energy, and mood against your baseline — then the cohort report: the effect size, its uncertainty, and the open questions. Your raw data stays yours and is never sold; anything published is combined across members and stripped of names, and founding members keep theirs forever.
