    Looks like we need to get it right, try telling this to a 15 yr old who has just emerged after 15 hrs kip
    WASHINGTON (AFP) - - Sleeping too little or too much can significantly increase the risk of mortality, according to a study conducted in Britain the results of which were published in the United States Saturday.

    A decrease in sleep duration among participants sleeping six, seven or eight hours was associated with a 110 percent excess risk of cardiovascular mortality, said the study authored by Jane Ferrie of the University College London Medical School in London.

    However, an increase in sleep duration among those sleeping seven or eight hours was associated with a 110 percent excess risk of non-cardiovascular mortality, it found.

    The study focused on 10,308 participants between 35 and 55 years of age.

    ""In terms of prevention, our findings indicate that consistently sleeping seven or eight hours per night is optimal for health," Doctor Ferrie said in a statement.

    She said mortality rates were lower in participants who first slept five to six hours or less but then reported extended hours of sleep.

    Meanwhile, higher levels of mortality for those who slept more than eight hours a day imply that sleep restriction should be considered, Ferrie said.

    The study is published in the December 1 issue of SLEEP, which is the official journal of the Associated Professional Sleep Societies, LLC.

    Yeah I've heard of this thing called "living" that apparently has a 100% mortality rate.

    There's a likely correlation between duration of
    sleep and life-circumstance, e.g. short hours with
    excess stress and long hours with depression or
    sickness (or teenagerhood ;)). The body is a complex
    time-keeper, messing with the proportions of activity
    and rest is bound to have some repercussions, or
    be caused by extraneous forces. It has been
    known for a while that night-time shift workers
    are more at risk of all sorts of trouble, I'm glad to
    see it more 'scientifically' verified.
