Professor Mohamed Elmasry suggests that daytime naps can serve as a “reset” for our brains, enhancing memory and cognitive function. Recent research indicates that one simple daily habit—taking a short nap—could significantly reduce the risk of dementia.
Elmasry, an artificial intelligence expert and professor at the University of Waterloo, explains that short, regular daytime naps allow the brain to rest and subsequently improve its function when awake. This practice has been shown to enhance performance in memory tests, leading Elmasry to conclude that naps refresh our memories.
“Napping provides our brain with a midday rest to recharge, rewrite memory, and dream,” Elmasry said. “Without this break, our brain works continuously from morning until late at night.” He added, “You can’t force your brain and body to nap longer than needed. If you’re working, use part of your noon break for a nap, even if it’s just resting your head on your desk. If you’re retired, nap whenever you feel like it, preferably in bed.”
In his book, iMind: Artificial and Real Intelligence, Elmasry also argues that increasing reliance on AI may accelerate cognitive decline and elevate the risk of dementia. He likens the brain to muscles, which require regular exercise to stay strong. Overdependence on AI can leave our brains underutilized.
“Your brain-mind is the highest-value asset you have or will ever have. Increase its potential and longevity by caring for it early in life and keeping both your brain and body healthy,” he writes.
According to the CDC, over 5 million Americans over the age of 65 are living with dementia. Despite this, research into effective treatments and cures is ongoing.
