Memory is a crucial part of our cognitive function, providing an essential backdrop for learning, thinking, comprehension, and really, who we are. However, memory problems are common, especially in those over 65. In fact, 40 percent of seniors experience some form of age-associated memory impairment, according to a 2002 study in the journal BMJ. Thankfully, there’s some good news for those who hope to retain their memory: a simple, brain-boosting health habit may help reverse your memory’s decline. Experts say by doing this one thing at night, you can significantly improve your memory, and reap other benefits, too! Read on to find out which health habit should become a part of your nightly routine.
Getting uninterrupted deep sleep can boost your memory
Scientists have long believed that a good night’s sleep is associated with the consolidation of memories. Now, a new study published this month in the Nature partner journal NPJ: Science of Learning has confirmed that longer durations of slow-wave sleep can measurably improve memory.
Your brain also seems to do this naturally.
Sleep occurs in two forms, REM sleep (which accounts for 20 percent of sleep) and non-REM sleep (which accounts for the remaining 80 percent). Non-REM sleep is broken up into four stages: stage one being the lightest sleep and stage four being the deepest. Slow-wave sleep—the stage in which we seem to consolidate memory—occurs in the third and fourth stage.
Experts believe that the brain also does this naturally while you sleep. “Over a typical night of sleep, a multitude of such memories are presumably consolidated, each reactivated to improve future retention,” says a 2021 study published in the journal Communications Biology.
Here’s how to get better deep sleep.
According to The Sleep Association, there are several things you can do to achieve longer periods of deep sleep. “The most important thing that you can do to increase your amount of deep sleep is to allow yourself adequate total sleep time. Often, individuals will deprive themselves of adequate total sleep. In addition to reducing deep sleep, REM sleep is also shortened,” their experts explain.
Additionally, they suggest building some period of “vigorous exercise” into your daily routine, noting that several studies have found that it helps to “increase or consolidate deep sleep.” Following a healthy diet—in particular a lower carb diet—has also been shown to increase slow-wave sleep, the sleep authority says.
Clearing your mind is important, too.
Experts say that your psychological state before bed can also affect how long you achieve slow-wave sleep. The ideal mental state for sleep is one of “serenity,” in which you feel “safe, comfortable and loved,” Rafael Pelayo, a clinical professor of psychiatry and behavioral sciences at the Stanford Center for Sleep Sciences and Medicine, recently told Newsweek.
For this reason, it’s important to resolve as many minor issues as you can before bedtime in an effort to ease your mind. Keeping a journal or writing up a “to-do” list for the next day may help you set your worries aside until the following day. “For most people, the only time they are alone with their thoughts is when they’re in bed. So, they’re in bed saying, ‘I gotta take care of this, I can’t forget to do this.’ Now you’re telling your brain to remember something, which is not allowing your body to go to sleep,” Pelayo warned. Instead, let the little things go for a better night’s sleep—and improved memory.
