One study found that it lowered brain activity and led to more stable sleep. Another study found people who used it slept more deeply. Studies are limited, but pink noise may also boost your memory. A recent study found that older adults who used it at night did better on memory tests the next day.

What does pink noise do to your brain?

Pink noise appears to amplify the power of the slower brain waves during deep sleep. When administered at night, it may help people fall asleep faster and get deeper, less fragmented sleep.

Is pink noise good for studying?

This same study also found that the slow brain wave activity produced by pink noise can help improve the brain's memory retention areas that are dependent on sleep to work. This means that pink noise could help your brain get to sleep, stay asleep, wake feeling rested, and be more productive when you're awake.
