Some fascinating research out of the Netherlands just challenged how hospitals (and probably many other 24/7 operations) organize night shifts.
The study — picked up by RTL Nieuws — explored what happens when you align schedules more closely with our natural circadian rhythm. In short: fewer mistakes, better rest, and happier employees.
What they discovered
Traditionally, many hospitals used shift patterns like:
- 11 PM – 7 AM (night)
- 7 AM – 3 PM (day)
- 3 PM – 11 PM (evening)
The researchers tried something different. Instead of having the night shift run until 7 AM — when the sun is already up — they ended it earlier, at around 4 AM. The early-morning hours were then covered by the day team starting sooner.
That seemingly small change allowed night-shift workers to get more dark hours of sleep, because they could go to bed before sunrise. The result? Better rest quality, improved alertness, and overall wellbeing.
Why it matters
When night workers finish at 7 AM, they often get home just as daylight peaks. Even with blackout curtains, it’s hard for the body to fully adjust — light exposure suppresses melatonin, disrupting the sleep cycle.
Ending the night shift at 4 AM, on the other hand, lets workers fall asleep while it’s still dark. Over time, that small shift can make a big difference to health and cognitive performance.
Building a tool to explore it
After reading the study, we wanted to see what that looks like in practice — how light and darkness overlap with typical shift schedules throughout the year.
So we built a small experimental ChronoRoster Tool to simulate it.
You can adjust:
- Location (to account for daylight variation across regions)
- Date (to see how winter vs summer affects sleep opportunities)
- Shift times and duration (to compare traditional vs. chrono-optimized schedules)
It’s not perfect, but it visualizes something important: the relationship between work, sleep, and light exposure — a factor often missing from workforce management systems.

Could workforce management software go “circadian-aware”?
At Soon, we’re thinking a lot about how data like this could shape better schedules. Imagine if your scheduling system not only balanced fairness and coverage but also factored in:
- Local sunrise and sunset times
- The amount of dark-sleep opportunity per shift
- Seasonal daylight changes based on location
We believe this kind of chronobiological intelligence could become a key ingredient in healthier, higher-performing workplaces — from hospitals to contact centers.
What’s next
The ChronoRoster experiment is just a start. We’d love to hear your thoughts:
- Should workforce software include circadian insights?
- Would you want to visualize daylight and darkness in your team’s schedule?
Let us know — and try the prototype tool to explore how simple timing adjustments might make a real difference in wellbeing and performance.
Would you like me to adapt this into a version optimized for SEO (with keywords like “healthy shift scheduling,” “circadian rhythm workforce management,” etc.) or keep it as this more narrative, product-linked version?
