“We need to study this further – one explanation could be that a more negative outlook influences both. However, it could be a sign that addressing sleep difficulties could promote a better perception of aging, which could have other health benefits.”
This study built on the PROTECT study, which is led by the University of Exeter and the Institute of Psychiatry, Psychology, and Neuroscience at King’s College London and funded by the National Institute for Health Research. Using online cognitive tests and lifestyle questionnaires, the PROTECT study investigates what factors contribute to people’s cognitive health in later life. In filling out the questionnaires, many PROTECT participants commented on their sleep patterns, according to the researchers.
