However, they could not discover any conclusive links between multimorbidity and prolonged sleep durations in healthy individuals at age 50.
Long sleepers did have a 35% higher chance of having another chronic illness if they already had one at age 50, possibly as a result of underlying medical issues, the researchers hypothesise.
According to a press statement from Jo Whitmore, a senior cardiac nurse at the British Heart Foundation who was not involved in the study, "Sleeping sufficiently enables your body to recover.
She said, "There are a variety of additional ways that poor sleep might raise the risk of heart disease or stroke, including by raising inflammation and blood pressure.
The study "additionally contributes to a growing body of evidence emphasising the value of receiving a decent night's sleep."
According to Sabia, having a good night's sleep necessitates practising "excellent sleep hygiene, such making sure the bedroom is quiet, dark, and the right temperature before going to bed.
"Removing electronics from the bedroom and avoiding heavy meals before night are also recommended. Getting some exercise and being exposed to light during the day may also help you sleep well.
An increased risk of being identified with several chronic diseases is linked to receiving just five hours of sleep each night or less, according to a recent study that used data collected over a 25-year period.
Sabia observed that prior studies have revealed that sleep lengths above or below this advised range may be linked to particular chronic conditions.
Separate American research, released last week, revealed that Americans frequently experience poor sleep and have a greater incidence of heart disease risk factors.
Researchers claim that what Sabia and her colleagues discovered supports their hypothesis that there is a link between getting less sleep and the likelihood of acquiring a number of chronic diseases.
