Good quality sleep is linked to good health, including cognitive health, said the Alzheimer’s Society.
The health charity added: “Researchers have also investigated whether there are effective treatments for poor sleep and whether these treatments can affect dementia risk.
“Some drug treatments for poor sleep, such as benzodiazepines, have been linked to an increased risk of dementia although the evidence behind this link is conflicting.
“Many treatments that have been suggested to improve quality of sleep involve lifestyle changes.
“Regular sleep regimes, eating schedules and diets, exercise, and ensuring exposure to bright light in the morning are all ways that you can improve your sleep quality.”
