If you tend to take naps during the day, it could be good for your brain.
A latest study published in the journal Perspectives on Psychological Science claims young and middle-aged people who take short naps during the day or afternoon can retain their memory better. Moreover, their memory doesn’t decline as long as they night-time sleep is not skipped.
According to the study authors, sound sleep in young and middle-aged people helps memory and learning. Michael K Scullin, director of Baylor University’s sleep neuroscience and cognition laboratory, said that as people grow older they wake up more at night and have less deep sleep and dream sleep – both of which are important for overall brain functioning.
For the study, researchers’ extensive review started with studies as long ago as 1967. They looked at over 200 studies measuring sleep and mental functioning, with participants aged between 18 and 29 years who were then categorised as young; aged 30 to 60 as middle-aged; and older than 60 as old.
They found a connection between sleeping well and mental health. Those who were sleeping better also had better cardiovascular health and fewer, less severe disorders and diseases of many kinds.
