Unusual sleeping patterns due to work can lead to lower intelligence
Working unusual shifts, varying
between morning and evening is likely to result in a reduction in
brain power according to new research by the British Medical
A sample of 3,000 people were
studied to monitor certain aspects of brain function such as memory
and information processing speed. The research found that those who
worked unusual hours performed worse, on average, than those who
worked normal hours.
The difference became more
noticeable over time, with those who had been working shift
patterns for ten or more years revealing the biggest difference
compared to their normal-hour counterparts.
The disruption to the body's
internal clock caused by shift work is already known to cause
health problems such as ulcers, cardiovascular disease and
metabolic syndrome. But until now, little was known about the
potential impact of alternating sleep patterns on brain
Those who work unsociable shifts can find it
difficult to get a good quality sleep, especially when returning
home after a night shift. Our sleep expert Dr Nerina says
that creating a regular winding down routine before bed will give
you the best chance of a good quality sleep.
