Newly published research suggests that getting less than the recommended seven or eight hours of sleep each night might not be as harmful as expected for some people's brains.
In light of new research about sleep and napping, specialists are urging Canadians not to get too fixated on finding the perfect sleep habits.
But sleep science is still a relatively new field, with much more research still to be done on how sleep patterns intersect with human health, according to a range of Canadian experts who weren't involved in the two new studies. That's a view shared by Dr. Ram Randhawa, a psychiatrist with the University of British Columbia's sleep disorders program.
Napping is something that sleep doctors traditionally advised against for their patients, the specialists consulted for this story said. The thinking was that sleeping during the day contributes to problems patients had sleeping at night.June 19 paper in the journal Sleep Health But the larger overall brain volume in habitual nappers "could suggest that napping regularly provides some protection against neurodegeneration by compensating for poor sleep," the researchers wrote.Dr. Brian Murray, the head of neurology at Sunnybrook Health Sciences in Toronto, pointed out that previous studies have also shown napping can help with cognition in people learning new things.
"If you feel groggy and sleepy during the daytime, you might choose to take a short nap and then if you respond well to it, that might be something you choose to do on occasion," Mak said.Randhawa noted that napping is common in many cultures around the world, but anyone who doesn't enjoy a midday slumber shouldn't feel compelled to change their routines.
