Do you want to perform better at work? A small change can make all the difference
We have reviewed a study published in the Harvard Business Review by Christopher M. Barnes that presents compelling evidence on the benefits of wearing blue-light-filtering glasses to improve sleep and work performance.
As we have pointed out on numerous occasions at Apricotte, the study examined how blocking blue light before bedtime affects sleep quality and work performance. Exposure to this light, which is common in electronic devices, inhibits melatonin production, making it harder to fall asleep. Wearing blue-light-filtering glasses allows melatonin levels to rise naturally, promoting a more restful night’s sleep.
The study was conducted with two groups of employees in Brazil: 63 managers and 67 customer service representatives. The participants alternated between wearing blue-light-filtering glasses and placebo glasses (with the same frames but without an actual filter) for just two weeks, and the results were remarkable:
- Increase in sleep duration: 5% more for managers and 6% more for customer service representatives.
- Better sleep quality: 14% higher among managers and 11% higher among sales representatives.
- Greater commitment to work: 8.5% higher among managers and 8.25% higher among sales representatives.
- Increase in helping behavior: 17% higher in both groups.
- Reduction in negative behaviors: 11% less in both groups.
- Improved work performance: Among managers, 7.1% based on self-assessment. In customer service, a 9% increase in customer ratings.
These findings suggest that a small change, such as wearing orange and red glasses with a blue light filter, can offer a significant return on investment in terms of productivity and well-being.
At Apricotte, we believe in the importance of blue light protection and its health benefits. If you’re looking to improve your sleep and daily performance, exploring blue light-blocking solutions could be a great first step.
