That's a problem, since a lack of sleep can negatively affect your physical and mental health. In a Good Housekeeping Institute sleep survey of more than 4,000 people, 76% reported they weren't sleeping well, and 56% felt they slept too little. Then again, sometimes it's silence that's hard to sleep through. Noise can keep you up at night, from your partner's snoring to a neighbor dragging out their garbage cans. We added two new choices, Sound+Sleep SE and Yogasleep Hushh+, and updated our Homedics pick to the SoundSleep. Original article on Live Science.We updated this article in March 2023 to ensure that all sound machines previously tested and vetted by the Good Housekeeping Institute were in stock and correctly priced. "I sleep really well to that."įollow Live Science, Facebook & Google+. "I'm a big fan of light rain and medium-distant thunder," Buxton said. If you're not one of those people, Buxton said, then go ahead and enjoy the soothing melody of a quiet storm. Some folks, Buxton also noted, react to gurgling water by having to go to the bathroom. "You can think you've got every notification off, every beep and boop for text and updates and whatever else, but if that phone is not off, you have a decent likelihood of an unintended interruption." "Phones are really terrible at protecting your privacy and quiet," he said. Nevertheless, given his study's and other studies' findings, Buxton cautions against would-be insomniacs coming to rely too much on a mobile device for cutting some Zs. "I think apps are wonderful for being able to dial those sounds in and they clearly anecdotally help people sleep," Buxton said. "Having a masking form of noise can also help block other sounds you don't have control over, whether someone is flushing a toilet in another part of the house, or there are taxis or traffic outside - whatever the acoustic insult is," Buxton said.Īll of which makes it understandable that water-themed sleep aids have proved so popular over the decades, across media ranging from cassettes to compact disks to MP3s to the mobile device apps of today. In either case, a sudden noise is good reason to stop sawing logs and see what the heck is going on.Īnother reason watery sounds can help us sleep? Non-threatening noises, especially when relatively loud, can drown out those sounds that might otherwise raise red flags in the brain's threat-activated vigilance system. "Primates will call to alert their troop about threats," or, in the case of primitive humans living in groups in the wild, "a scream might be someone in the tribe being eaten." "We're mammals, but we're specifically primates," Buxton said. We humans, it appears, are biologically hard-wired to respond to noises that come out of nowhere because they can be very bad news.
Meanwhile, the sounds of a helicopter and traffic, when reaching the level of a shout at 70 decibels, still did not wake participants as frequently as alarms, ringing phones and even relatively quiet human conversations, which again can feature that jarring, no-noise-to-peak-noise delivery. Even at low volumes of around 40 decibels - a whisper, essentially - alarms from hospital equipment aroused study participants from shallow sleep 90 percent of the time, and half the time from deep sleep. This key acoustic distinction between abrupt threat and gradual non-threat was borne out in a 2012 study by Buxton in a hospital setting. "With a scream or a shout, it's 'no noise' and then it goes directly to high pitch," Buxton said. That's in stark contrast to a scream or a ringing phone suddenly piercing a silence, reaching peak loudness almost instantly. "The type of noise defines if you will wake up or not, controlling for the volume, because the noise information is processed by our brain differently," Buxton said.įor instance, although the sounds of crashing waves can vary considerably in volume, with quiet intervals followed by crescendos, the waves' hubbub smoothly rises and falls in intensity.
