Lights Out for Late-Night Workers
For many employees—and especially for working parents—the best time of the day to get some quality work done comes when they are out of the office and the kids are asleep. This is the new 9–11 p.m. work shift, and although the short-term benefits of leveraging these two hours for work may seem to be in the best interests of employers and employees, new evidence suggests that the long-term problems associated with this practice outweigh its benefits.
In particular, research shows that working right up until it’s “lights out for bed” is highly disruptive of sleep, which in turn harms employee engagement and performance the next day. Lack of performance on that next day then prompts even more late-night work, which creates a vicious cycle of sleep deprivation. Indeed, the mere practice of looking at one’s smartphone after 9 p.m. has demonstrable negative effects on sleeping patterns. The blue light emitted by a smartphone is the single most disruptive band of light when it comes to inhibiting the sleep-promoting hormone melatonin. Combining this biological reaction with biological reactions caused by workplace stress is a recipe for disaster. As researcher Chris Barnes notes, “Smartphones are almost perfectly designed to disrupt sleep.”
The negative effects of sleep deprivation on employee performance and safety are well known, and for some...
