From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it’s investigating the financials of Elon Musk’s pro-Trump PAC or producing our latest documentary, ‘The A Word’, which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.<\/p>\n
At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.<\/p>\n
The Independent is trusted by Americans across the entire political spectrum. And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.<\/p>\n

The ambient and steady, static-like tone from pink noise is similar to tapes of heavy rainfall or ocean waves, and aims to soothe the brain into a deep slumber. Pink noise contains lower frequencies of sound than white noise \u2013 which is the same as TV or radio static \u2013 and there are machines that provide people with both kinds of noise.<\/p>\n
Recent research on its effectiveness has been largely positive, with a 2019 Northwestern study finding that the noise could boost deep sleep in patients with mild cognitive impairment.<\/p>\n
But a new warning from researchers at Penn Medicine cautions that pink noise may actually be doing more harm than good for your sleep quality.<\/p>\n

REM \u2013 or rapid eye movement \u2013 sleep helps protect against dementia and improves brain development, learning and mood, according to Harvard Health.<\/p>\n
\u201cREM sleep is important for memory consolidation, emotional regulation and brain development, so our findings suggest that playing pink noise and other types of broadband noise during sleep could be harmful – especially for children whose brains are still developing and who spend much more time in REM sleep than adults,\u201d Dr. Mathias Basner, a professor of Sleep and Chronobiology in Psychiatry, said in a statement.<\/p>\n
The participants, who had not previously used these noises to fall asleep, sleep for eight hours a night under different conditions. <\/p>\n
They were exposed to aircraft noise, pink noise, both with and without earplugs. <\/p>\n
In the morning, the Penn doctors asked the participants to complete tests and surveys that would measure sleep quality, alertness and other health effects. <\/p>\n
Earplugs were found to be significantly more effective at protecting sleep against traffic noise, and the combination of pink and aircraft noise shortened deep and REM sleep compared to noise-free nights.<\/p>\n

This wasn\u2019t the case if they wore earplugs.<\/p>\n
The researchers said their results highlight that these noise machine sleep aids need to be studied more thoroughly, noting that white noise videos on YouTube have racked up hundreds of millions of views.<\/p>\n
For young children watching these videos to help them fall asleep, Basner added, the effects could be even more pronounced. <\/p>\n
And it is common that parents use sound machines to help their toddlers or newborns fall asleep. <\/p>\n
REM sleep makes up a quarter of infants\u2019 sleep.<\/p>\n
\u201cOverall, our results caution against the use of broadband noise, especially for newborns and toddlers, and indicate that we need more research in vulnerable populations, on long-term use, on the different colors of broadband noise and on safe broadband noise levels in relation to sleep,\u201d he said. <\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
