Lack of sleep ‘increases heart disease and stroke risk’
Researchers in the US have discovered that a lack of good quality sleep has been linked to a higher risk of stroke and heart disease.
According to the study, inadequate slumber is connected to increased levels of inflammation in blood vessels, which has been demonstrated to be risk factors in such conditions.
The team from the Emory University School of Medicine in Atlanta, Georgia, found improving sleep quality and duration could lower the threat of cardiovascular disease.
Dr Alanna Morris, who led the study, presented her findings at the American Heart Association’s 2010 Scientific Sessions and called for more investigation into the subject.
A total of 525 individuals of middle age were studied for the research, which discovered that levels of inflammatory hormones were up to 25 per cent higher in those sleeping for six hours or fewer per night.
Those seeking more comfortable bed frames and mattresses to improve their rest may also be interested to learn that another study presented at the same event by US specialists suggested the risk of cardiovascular disease was higher in women whose jobs involved high levels of strain compared with those whose roles did not.
