Moen Probes Biphasic Sleep for 3 Million UK Night Workers as Dementia Risk Rises 36%

Summary
11,000 paper summaries are being reviewed by Dr. Line Victoria Moen to test whether splitting sleep into two blocks can better support night-shift workers; full results are due later this year.
Arctic Circle tracking with Oura Rings showed many workers slept from about 9 a.m. to 1 p.m. and again later in the afternoon, suggesting the body clock may resist one long daytime sleep.
20-to-50-minute naps during or after shifts have already been linked in healthcare studies to better alertness, improved focus and less drowsy driving, but Moen says research on biphasic sleep remains fragmented and lacks a standard definition.
More than 40,000 UK Biobank brain scans and a 13,000-worker Swedish study add to concern over disrupted sleep, with shift work in midlife associated with a 36% higher dementia risk alongside evidence tying poor sleep to heart disease and cancer.

The Moen Probe (2026): Can Biphasic Sleep Transform Health Outcomes for Night Shift Workers?
Overview
Dr. Line Victoria Moen is leading 'The Moen Probe,' a new investigation exploring whether biphasic sleep—dividing sleep into two periods—can help night workers reduce health risks. This research aims to find practical solutions for people whose jobs disrupt normal sleep patterns, focusing on improving their well-being and health outcomes. The study highlights the urgent need for innovative strategies to support night shift employees, who often face serious health, social, and economic challenges. By proactively seeking evidence-based recommendations, 'The Moen Probe' could shape future workplace policies and improve the lives of night workers.
