The overall conclusion was that brainwave entrainment is an "effective therapeutic tool". This binaural beat research paper nicely summarises 20 previous peer-reviewed studies into the psychological effects of Brainwave Entrainment. Proof: Therapeutic Qualities of Hemi-sync recordingsġ) "A Comprehensive Review of the Psychological Effects of Brainwave Entrainment", Tina L Huang, PHD, and Christine Charyton, PHD. For example, Alpha waves have a frequency range of between 7 – 14 Hz and by tuning the brain into the Alpha state by use of binaural beats it creates a link between the conscious and subconscious where the mind is far more responsive to information and hypnotic suggestion is far more easily absorbed. When listening to Hemi-sync recordings on headphones your brain will become entrained to the same frequency cycle and begin to function on the same level. Hemi-sync recordings are made up of two slightly differing frequencies, the difference of which your brain perceives as an oscillation. Or listen to the sound mix as you drift off to sleep.A 40 minute journey from Alpha through to Theta and finally resting in Delta, this recording is designed to induce deep healing sleep through binaural frequency brain entrainment. Add delta beats to your favorite meditation that prepares you for bed to enhance the onset of deep sleep. You can listen to them, but you can also mix the beats with music or other sounds you find relaxing and conducive to sleep.
There are a few ways to use binaural beats. You can use delta beats whenever you feel particularly stressed or anxious and want to sleep more deeply. In one study, delta frequencies in binaural beats had the greatest effect on anxiety.
Studies of binaural beats have found that they reduce anxiety in specific situations, such as before surgery. You can use sounds alone or with music that creates a beat to match any type of brain wave, including delta. Binaural beats are when two different frequencies combine so that the brain perceives just one beat or frequency. One way to do this is with binaural beats and delta wave music. Understanding what delta waves do, it might be possible to use them to get more high-quality, deep sleep. If your sleep gets disrupted throughout the night, you might not get through enough cycles or be jolted out of deep sleep too often. Poor quality sleep can lead to inadequate delta sleep. During deep sleep, the body releases human growth hormone, which explains some of the benefits of this sleep stage. It could be important for improving heart health, a functioning immune system, tissue repair, and metabolism. Sleep scientists believe this is when your brain cleans itself of waste.ĭelta sleep might also be when you consolidate memories and learning. Even though it accounts for much less time, deep, delta sleep is essential for proper rest and brain functioning. The Importance of Delta Wave Sleepĭuring a normal night of sleep, you spend most of your time in N2. Here your brain activity is similar to wakefulness. These are the lowest-frequency brain waves at just 1 to 3 Hz.įrom N3, you transition to REM sleep, and the brain becomes more active.
Non-REM sleep is divided into three substages: The stages of sleep include non-REM and REM (rapid eye movement). Delta waves are characteristic of deep sleep, and it might be possible to harness them to improve sleep.
When you sleep, your brain cycles through several stages, from light to deeper sleep and back again during each stage, your brain also shifts through different frequencies of electrical activity, known as brain waves.
