Shift Work Sleep Adjuster
Plan sleep and light exposure transitions when adapting your circadian rhythm to rotating shift work.
The Shift Work Sleep Adjuster generates progressive sleep shift programs. By calculating adjustments over available transition days, it provides sleep schedules and light exposure windows to mitigate roster changes.
How to Adjust Roster Sleep
- Enter your current typical wake time.
- Input your new target shift wake time.
- Set the number of available transition days.
- Review the daily calendar mapping sleep, wake, and light windows.

Frequently Asked Questions
How fast can the circadian rhythm adapt?
On average, the human circadian clock can adjust by about 1 to 1.5 hours per day. Trying to shift faster can trigger cognitive strain.
Why are light exposure windows important?
Light exposure suppresses melatonin synthesis in the pineal gland. Exposing yourself to light at the correct times anchors your new rhythm.
How should I manage sleep environment transitions?
During daytime sleep transitions, use blackout curtains, white noise machines, and keep bedroom temperatures cool.
