Nature sounds5/19/2023 ![]() Then the spacecraft beamed the recordings home, where scientists put on some headphones and pressed “Play.”Īt first, they heard nothing. The Perseverance rover arrived last year, stretched its wheels, and got to work examining interesting-looking rocks, with the mics listening in. They put two microphones on a Mars rover and dispatched it to the red planet, dropping it off at the edge of a crater, near an area that was a river delta billions of years ago. So it might seem strange that anyone would want to send a microphone to deep space, but scientists and engineers have done just that. Sound, or the absence of it, is one more way our home fulfills Carl Sagan’s description of Earth as “a lonely speck in the great enveloping cosmic dark.” The moment is meant to soothe the worried character, but it is also a reminder to all of us that our planet is very noisy and the rest of the solar system-the rest of the universe, really-is not. When the physicist puts the buds in, he and the audience hear the distinct sounds of Earth: crickets, rain, the low rumble of thunder. You may find that, like the research study participants, not only will you be able to sleep better but also more when you listen to nature’s symphony.There’s a lovely scene in Interstellar-one of the best space movies in history don’t argue with me-when the NASA pilot tasked with saving the day hands a pair of headphones to his fellow space traveler, a physicist, who’s having a difficult time on their perilous journey through space. Enjoy listening to different sounds to hear what appeals to you. Free nature sound apps such as Noisli or Slumber are available for download onto your smartphone. Participants were productive at focused tasks when listening to nature.įor a restful night’s sleep, you can easily bring the sounds of, say, a rainforest or a waterfall into your bedroom. Additionally, reaction time while on task was slower.īy contrast, when hearing nature sounds, the brain decreased the fight-or-flight reaction and increased the rest reaction. This kind of attention includes worrying, depression, and forms of anxiety. ![]() ![]() During this time, they received brain scans and their heart rates were monitored for changes in their nervous systems.įrom studying the fMRI results, researchers noticed that when listening to artificial sounds, the brain began a pattern of inward focused attention. Seventeen study participants listened to alternating sounds of natural and manmade environments as they performed tasks. This research study, published in Scientific Reports, is noteworthy for the use of heart-rate monitors, functional magnetic resonance imaging scans (fMRI) and social experiments to determine why the body reacts so positively to natural environments. This opposite response to “fight-or-flight” helps the body relax and fall to sleep. Researchers at Brighton and Sussex Medical School in England have determined that nature’s sounds, in contrast to artificial noise, build up the “rest-digest” response instead. These stress hormones make a good night’s sleep very difficult. The nervous system prepares to fight or flee a threatening situation by releasing the hormones cortisol, adrenaline, and noradrenaline. Researchers have discovered that nature sounds change the connections in our brains, taking down the body’s fight-or-flight response. Fight or flight happens when we are under extreme stress. Nature’s music can restore us by helping us relax, and now we know why. We already know the soothing power of nature’s sounds: When we hear a mockingbird trill or a brook babble, our minds calm and our racing hearts slow down. ![]() Listening to nature helps us sleep better.
