![]() ![]() A difference of 0.1-4 Hz are associated with deep sleep. When that difference is between 5-8 Hz, you get Theta waves that are associated with deep relaxation and certain stages of sleep. When the brain hears these different frequencies, it perceives a third tone based on the difference between the two frequencies (in this case 5 Hz) and creates a low frequency pulsating beat. For instance 300 Hz in the left ear and 305 Hz in the right ear. My friend Brenda swears by "binaural beats." Binaural means “relating to two ears." In this case, slightly different frequencies of sound are played into each ear. It keeps the room cool while creating a hum that drowns out sounds. Or you could keep it simple and use an indirect fan. (Interestingly, the subjects were also able to recall almost twice as many word pairs shown to them the previous night after sleeping with pink noise, vs. Research has showed that compared with no noise, the pink noise corresponded with a longer duration of deep sleep. Pink noise is often found in nature, such as waves lapping on the beach, leaves rustling in the trees, or a steady rainfall. ![]() Then there's "pink noise," which is like white noise, but instead of having equal power across frequencies, pink noise comes out louder and more powerful at the lower frequencies (it has been likened to white noise with the bass turned up). There was even a study showed that patients in a coronary care unit were able to sleep much better when white noise blocked the sounds of the busy hospital ward. An old water heater or car going by can suddenly sound much louder in the still of the night, so this consistent sound blends it all together. Oftentimes, it's not the noise that is bothersome, but the change in noise frequency. It may also mask outside sounds such as a car door slamming or voices that can change frequencies and cause a disruption in sleep. The most popular colors of noise for sleep are white and pink.Ī "white noise" machine may help with a gentle constant whir in the background. The various colors of noise depend on the frequencies that affect the power spectrum of a noise signal. Pink, blue, violet, brown, white, black and gray. Speaking of blue, there’s colorful noise. Be careful about the videos that are available since screens may emit blue wavelength light that is stimulating and can have counteractive effects. Again they may work for some, but those different sounds can be distracting or have background sounds like birds or thunder that can be jolting. There are also sleep apps, stations and videos with different nature sounds like waterfalls, rain, animals, even city sounds. Others like listening to music, but some may get caught up in in it, may hum or sing along, or follow the beat. Guided meditation for sleep can certainly be a relaxing option with someone who is able to immerse themselves. Was it Emma Thompson – only with a slightly lower pitch and faint lisp? I’m not sure, but I just couldn’t get into the meditative state I was supposed to be in. ![]() I just couldn’t get over the fact that her voice sounded familiar. The female voice encouraged me to separate myself from my thoughts and get caught up in the present moment of relaxation. Sleep always catches my attention, and I was curious. I was recently on a flight and noticed one of the options for in-flight entertainment was an audio program for sleep. There are a number of different noise options. MORE ON SLEEP: Getting in sync with your circadian cycle is a key to healthy sleep How can you sleep when it’s so noisy? What’s the solution? It’s noise. So now the silence is broken with your neighbor’s car alarm or construction or the ice maker or barking, beeping, yelling, dripping, ticking. How can you sleep when the silence is so loud? When all you can hear is your breath and your thoughts? Light-emitting electronics like the TV and computer are off. Bedtime has arrived, and now it’s time to set the stage. ![]()
