Extended sleep is associated with decreased pain sensitivity

PortraitA study published in the journal Sleep, has shown that increased sleep may reduce pain sensitivity.  Eighteen healthy, pain free adults, aged 21-35, took part in this 4 night study.  Nine of the participants maintained their normal sleep habits and the other participants stayed in bed for 10 hours.  Pain sensitivity was measured by the amount of time participants could keep their finger on a heat source.  Those in the extended sleep group slept around 2 hours more per night and had decreased pain sensitivity indicated by a 25% increase in the length of time to touch the heat source. What other benefits are associated with increased sleep?
