Taking short naps during the day could well be the key to helping to protect the brain's health as we age and help to reduce the risk of developing dementia.
It's thought the practice helps preserve brain volume, a quality linked with healthy cognitive functions and a lower risk of not just dementia, but also other diseases.
Previous research suggested long naps could be an early symptom of Alzheimer's disease, but the latest research reveals that brief snoozes can improve people's ability to learn and fight against brain shrinkage.
