Wake up sleepy head! A recent study of more than 13,000 Australians has found nearly 40 per cent of us have fallen asleep at their desk or during a meeting. The poll, by Central Queensland University, also found that more than 30 per cent of us have called in sick because of a lack of shut-eye.

Study author Professor Drew Dawson said that the survey, the largest ever done on the sleeping habits of Australians, showed that intrusions in our bedrooms are responsible for us nodding off on the job. The study participants, ranging from Gen Y to 70-year-olds, reported pets, laptops, iPhones and snoring partners as the main culprits for interrupting our slumber time.

“What used to be the bedroom, is now a room that happens to have a bed in it. There's so much else going on in people's bedrooms these days that it's very difficult for them to basically relax and get to sleep,” said Professor Dawson.
