Bored or Nightmare?
Falling asleep at your desk?
Canadian researchers found that sitting all day can set you up for sleep apnea, a condition that usually causes daytime drowsiness.
The link: When you sit for long periods, water and blood pool in your legs. Later, when you lie down to sleep, gravity causes the accumulated fluid to flow to your neck, putting pressure on your upper airway that can cause it to collapse, says study author Douglas Bradley, MD.
The resulting mini-suffocations can leave you sleep deprived. To reduce your risk, take a walk each hour.
