Using wearable technology (closed loop acoustic stimulation) to improve sleep quality and work outcomes

Area of Science:

• Neuroscience
• Sleep Science
• Organizational Behavior

Background:

• Employee sleep quality significantly impacts workplace behaviors and performance.
• Traditional methods to improve sleep duration face practical challenges.
• Advancements in sleep technology offer potential for novel interventions.

Purpose of the Study:

• To investigate the effects of closed loop acoustic stimulation on employee sleep quality.
• To examine the subsequent impact of improved sleep on work engagement, task performance, organizational citizenship behavior (OCB), and counterproductive workplace behavior.
• To identify potential boundary conditions, such as age, for the effectiveness of this intervention.

Main Methods:

• A 4-week within-subjects field experiment involving 81 employees.
• Participants used headbands in either active mode (closed loop acoustic stimulation) or sham mode (control).
• Sleep quality and next-day work behaviors were measured.

Main Results:

• Closed loop acoustic stimulation significantly improved next-day work engagement, task performance, and OCB.
• No significant effect was found on counterproductive workplace behavior.
• The intervention demonstrated greater efficacy in younger employees.

Conclusions:

• Closed loop acoustic stimulation is a viable, cost-efficient method to enhance employee sleep and related work outcomes.
• This intervention offers benefits without requiring increased sleep duration.
• Age moderates the effectiveness of closed loop acoustic stimulation, highlighting a key boundary condition.
