Scientists at Northwestern University are studying how short pulses of pink noise can enhance the slow brain waves of deep sleep.

Kabosu, whose nickname was Kabocha — Japanese for “pumpkin” — died Friday morning after she “fell into a deep sleep,” her owner wrote in Japanese in a blog post, which was computer-translated.

The brain needs to wind down long before bedtime to get the restorative deep sleep that helps the body function, said Melissa Milanak, an associate professor at Medical University of South Carolina specializing in sleep health.

That suppresses melatonin production, delaying deep sleep.

University of California, Irvine biomedical engineering researchers have uncovered a previously unknown source of two key brain waves crucial for deep sleep: slow waves and sleep spindles.
