Key Takeaways
- 01Staff from a UK higher education institution ( n = 28) with short sleep duration (<7 h) and elevated cardiometabolic risk were randomised to SEI or SI. [Du Preez A (2026)]
- 02Workplaces offer a key setting for health improvement interventions, given their reach and potential to promote lasting behaviour change. [Du Preez A (2026)]
- 03While diet and physical activity (PA) are common targets, sleep remains an underexplored yet influential factor in employee health. [Du Preez A (2026)]
- 04These disturbances occur despite adequate opportunity and conditions for sleep [], and they result in general dissatisfaction with sleep quality and various daytime impairments. [Żełabowski Kacper (2025)]
