Research published earlier this year in the journal Scientific Reports found that listening to sounds from nature, like a rainforest soundscape or a babbling brook, can trigger a relaxation response in the brain. Soothing background sounds can also cover up manmade sounds like voices or traffic, which were shown in the study to have the opposite effect.
This secret was revealed in a 1981 book called "Relax and Win: Championship Performance," but has gained traction online in recent months. It's a meditation method designed specially for soldiers trying to fall asleep in difficult conditions. It's said to work for 96 percent of people after six weeks of practice. Here's how the Independent describes it:
Adjust the thermostat. If you’re too hot or too cold at bedtime, sleep isn’t going to come easy. While there’s no ideal temperature for everyone, most people sleep comfortably when the bedroom is between 60 and 67 degrees. As you start to feel drowsy, your body temperature drops, which in turn helps you drift off to sleep. A cooler bedroom facilitates that. Don’t cool it off too much, though — shivering in bed isn’t conducive to a good night’s sleep.
So I can confidently say this decades-old technique worked for me. Mind you, it didn’t work every night. Some nights during that second week I didn’t get that “release” after my visualization. But as the weeks went on, the trick seemed to work more often than not. And it seemed to work more effectively when I visualized myself in a velvety hammock instead of in a canoe, so it helps to switch up visualizations to see what works best.
Sleep is an important part of your daily routine—you spend about one-third of your time doing it. Quality sleep – and getting enough of it at the right times -- is as essential to survival as food and water. Without sleep you can’t form or maintain the pathways in your brain that let you learn and create new memories, and it’s harder to concentrate and respond quickly.
