Men are more sleep-deprived as they find sleeping less is masculine, researchers say.

Authors Nathan B. Warren and Troy H. Campbell, from the University of Oregon, conducted 12 experiments involving 2,564 US participants.

In one test, the men were asked to describe attributes of a male character, one who was "very masculine and manly" and another who was "not very masculine and not very manly".
