Wearing a continuous positive airway pressure (CPAP) mask at night could help people who are pre-diabetic, according to studies.
Researchers have determined that the mask keeps the airway open and prevents sleep interruptions. The CPAP mask is already used by people who suffer from sleep apnea.
They supervised 39 adults in a sleep lab for two weeks and found those who wore the mask were better able to use their body's insulin.
The study suggest as many as two-thirds of type 2 diabetic patients may not realize they have sleep apnea.
