Researchers in Trinity have identified a possible link between sleep deprivation among older adults and poor health.
The study also found that people aged 50 and older who are retired, unemployed or taking antidepressant medication sleep more than those outside these categories.
The research was carried out by The Irish Longitudinal Study on Ageing (TILDA), which is based in Trinity, and was published in the Journal of the American Geriatrics Society.
The research found that the amount of sleep a person gets increases with age, with adults aged 50 and older sleeping for an average of seven hours and 42 minutes per night.
In a press statement, TILDA researcher and lead author Siobhan Scarlett said: “While sleep duration is not recognised as a public health concern, this research highlights an important subset of Irish adults who are not meeting the recommended guidelines for sleep duration and are at increased risk of negative health outcomes.”
“Awareness of the impact of sub-optimal sleep duration and factors potentially driving these patterns, particularly those which are modifiable, is important”, she added.
number of behaviours which if changed, can improve sleep quality and duration.
“Addressing the underlying causes of undesirable sleep patterns may help to facilitate improvements in the health and well-being of our older population.”
Some 14 per cent of participants recorded sleeping less than the recommended nightly amount. The recommended sleep range for adults aged 65 years and older is seven to eight hours.
TILDA’s principal investigator, Prof Rose Anne Kenny, said in a press statement: “Sleep duration is an important contributor to physical and mental health.
“There are a number of behaviours which if changed, can improve sleep quality and duration.”
“These apply to all age groups but particularly mature adults, almost one third of whom experience impaired sleep duration according to our recent data”, she added.
