Sleeping for an extra hour a night 'helps beat pain'
Sleeping for an hour or more extra a night can dramatically improve an individual’s alertness and reduce their sensitivity to pain, say scientists.
In fact, say the researchers, getting nearly ten hours a night – rather than the recommended eight – is more effective at reducing pain than taking the drug codeine. The study used 18 healthy, pain-free volunteers who were randomly assigned either four nights of their normal sleep pattern or four nights of ten hours in bed.
The American researchers measured daytime sleepiness using the multiple sleep latency test – a standard method used by doctors to diagnose sleep problems in which brain waves, eye movement, heart rate and muscle tone are measured. Pain sensitivity was assessed using a heat source.
