The Sound of ‘Pink Noise’ Improves Sleep and Memory

Deep sleep is critical to maintaining a robust memory, but both decline with age. A small new study published in Frontiers in Human Neuroscience suggests that one easy way for older adults to get deeper sleep and stronger memories is to listen to a certain soothing sound called “pink noise”—a mix of high and low frequencies that sounds more balanced and natural than its better-known cousin, “white noise.”

It may sound strange, but previous studies have found that playing so-called pink noise during sleep improves the memory of younger adults. “We wanted to see if it would work in older people, too,” says senior author Dr. Phyllis Zee, professor of neurology at Northwestern University Feinberg School of Medicine. Older people tend to get less slow-wave sleep and are at greater risk for memory impairment.

Zee and her fellow researchers had 13 adults ages 60 and older spend two nights in a sleep lab. On both nights, the participants took a memory test at night, went to sleep wearing headphones and an electrode cap, and repeated the memory test in the morning.

Never mind the state it's in as I tidy everything up prior to publication. Don't let good material go to waste - and so much does. In the interests of the environment we should always try to re-cycle everything, especially jokes. You know that makes sense! You may find some historical stuff here, but this does not really matter as humor is fairly timeless.
