First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at whether working night shifts for just three nights in a row can disrupt bone health. Twenty healthy adults aged 20-40 either followed a normal sleep schedule or stayed awake at night and slept during the day. Researchers measured bone turnover markers to see if the body's bone-building and bone-breaking processes become unbalanced. The goal is to understand why shift workers face higher osteoporosis risk.
