Healthy sleep habits include sufficient sleep, regular bedtimes and established sleep routines. The responsibilities of paid and unpaid work that arise during the daytime are assumed to haunt us at night as well, eventually affecting these sleep habits. A long-term comparison of sleep duration from 1966 and 1999 time-diary data shows that sleep duration has not declined to the large extent that is generally assumed. Moreover, analyses of timing of sleep and sleep routines using time-diary data from 1999 and 2004 also do not show much evidence of this assumed decline. On the contrary, increasing work and family responsibilities positively affect regular bedtimes and sleep routines.
