Socialising can cause sleep problems

London, Nov 1 (IANS) Extroverts who regularly socialise for half their day are more vulnerable to sleep deprivation than introverts, say researchers.

The study, which looked at 48 people, suggests that one’s waking experiences affects sleep quality, according to the journal Sleep.

The volunteers were assessed for personality type and then half were put into a socially enriched environment and half into isolation, reports the Telegraph.

Their quality of sleep was then observed by the researchers from the Centre for Military Psychiatry and Neuroscience at Walter Reed Army Institute of Research in Maryland, US.

“Extroverts exposed to socially enriched environments showed greater vulnerability to subsequent sleep deprivation than did extroverts exposed to an identical but socially impoverished environment,” said lead author Tracy Rupp.

“The ability of introverts to resist sleep loss was relatively unaffected by the social environment.

“Overall, the present results might also be interpreted more generally to suggest that waking experiences, along with their interaction with individual characteristics, influence vulnerability to subsequent sleep loss,” concluded Rupp.
