The function of sleep is to enable the body to rest and
restore itself, but failure to get a proper night's shut-eye could
significantly impede this process, an expert has stated.
Marianne Davey, director of the British Snoring & Sleep Apnoea
Association, said restful sleep is one of the most important daily
functions the body has to go through, as during this time a number
of hormones are released that stimulate the body's cells to repair
These hormones cannot be released during the time a person is
awake, as other chemicals are needed to keep a person alert and
ready to tackle whatever the day throws at them.
As a result, without a proper amount of restful sleep, the body
will be unable to effectively repair itself and therefore people
could become more prone to ill health.
Ms Davey commented: "Brain function suffers most from lack of
sleep as it reduces the capacity for decision making, impairs
judgement, affects memory and concentration.

and there is increasing evidence that there is a link between lack
of sleep and a higher risk of major illnesses such as heart
disease, diabetes, some cancers and obesity."
She added that poor sleep patterns can therefore be a major worry
for individuals, as if the proper hormones are not released during
sleep, people can wake up feeling sluggish and less able to
function properly during the day.
Ms Davey's comments follow the publication of new research from
Ofcom as part of its annual Communications Market Report, in which
it highlighted the growing problem of technology interfering with
the ability of people to switch off effectively from their
According to the findings, the average person now sends more than
200 text messages per month and this increasing intrusion of
technology into people's lives means they are less able to wind
