No, you are not dreaming. You really can boost your brainpower while you snooze. Try these seven tips.
CHANGE THE COLOR OF YOUR NOISE
White noise (such as the hiss of a radio tuned to an unused frequency) can help you sleep more soundly, but what scientists call pink noise could help you remember more. According to a small study from Northwestern University, the lower-frequency sounds of pink noise, such as the rush of a waterfall or steady rain, improved older adults’ deep, slow-wave sleep, the stage considered important for consolidating memories. When study participants listened to pink noise while they slept and then took a memory test the next morning, they scored three times higher than participants who didn’t sleep with that kind of background sound. Don’t live near a waterfall? Download an app such as the aptly named Pink Noise.
