Regular napping can significantly benefit the brain, according to a new study from University College London. Results showed that people who nap regularly have 15 cubic centimetres larger brains on average – the equivalent of staving off brain aging by three to six years. However, the research found that naps should be kept to under 30 minutes and may only be carried out by retired individuals and those not bound by the pressures of work. The study analysed 35,000 people aged between 40 and 69, with the genetic “nappers” having a 15 cubic centimetre larger brain volume on average.
