Obstructive Sleep Apnoea Syndrome in Train Drivers

Obstructive sleep apnoea syndrome (OSAS) is a sleep disorder in which the back of a person’s throat closes up during sleep and they stop breathing until their brain wakes them up. OSAS is an important health issue for the rail industry because when the condition goes unrecognised in individuals and remains untreated it can result in excessive sleepiness and increased risk.
