Insomnia Linked to Higher Risk of Stroke, New Study Finds

People with one or more self-reported symptoms of insomnia have a 16% increased risk of developing stroke, according to a study by scientists in the US. The link was stronger in participants under 50, where those with five to eight symptoms had nearly four times the risk of having a stroke. The study suggested that improving sleep quality through therapies could help reduce this risk. The research involved more than 31,000 participants, with an average age of 61, who had no history of stroke at the beginning of the study and were followed for an average of nine years.
