In simplest form, they are an audio technology which are used for (safe) brainwave entrainment. Our subconscious mind operates, throughout the day and night, in various brainwave state frequencies, measured in cycles per second (Hz) These frequencies range from the slowest (Delta) frequencies experienced in deep, dreamless sleep and in deep meditation where your conscious-awareness is fully detached, to the fastest (Gamma) frequencies associated to stimulating flow states, high-level thinking and information processing. There are actually 5 known brainwave state frequencies each having their own set of unique characteristics:
I also believe that the dangers of brainwave entrainment should be further explored as well. There are relatively vague benefits, but it remains unclear as to whether entraining certain frequencies may be detrimental to performance or induce harm. Despite the fact that brainwave entrainment has existed for a long term, it remains an understudied niche in neuroscience.
7. Connecting with nature. Whether it’s finding a window with a good view or tackling a hike up a beautiful mountain peak, there is just something about being outside that can be grounding. You can walk on the grass with bare feet, watch snow fall or listen to birds chirp in the distance. Utilizing your five senses is a stress-reducing technique that’s versatile enough to exercise anywhere.
When blended with musical sounds, brainwave entrainment frequencies induce specific states of mind, which are the result of those brainwaves, delivering them in pleasing and relaxing audio tracts for use with and without stereo headphones. For example, alpha and theta waves, because they exist at the borders between conscious and unconscious thought, are especially rich and useful for tapping into and stimulating subconscious processes.
Some research suggests that the benefits from brainwave entrainment can last a lot longer, and still be seen for some time after you've stopped using it. Study participants have still maintained improved test scores a few weeks after the stimulation had ceased. Research on the long-term benefits has so far been minimal though, so how long the effects last is still up for debate.
When stress attacks, it can feel like your whole world is crashing down. Remind yourself what’s good in your life with a quick gratitude round-up. “Studies show gratitude techniques like counting your blessings can be a significant stress reducer,” Dr. Serani says. “Gratitude research reports that those who utilize daily gratitude reflections have higher levels of positive emotions, life satisfaction, vitality, optimism, and lower levels of depression and stress.” Reminding yourself of the good things in life can put stress in perspective. “Studies show that cultivating an optimistic mindset can help you maintain a positive mood,” Whitaker says. “When you are positive and grateful, you are able to handle difficult situations better.” Just look out for these stress relievers that actually backfire.
Brainwave entrainment is a field of study and endeavor founded in the same physiological and psychological processes that make music, drumming, and chanting so powerful as methods for transforming the mind and spirit and aiding in healing of the body. These processes involve how the electrical energy in our brains synchronizes with sounds and visual stimuli, producing a particular brainwave frequency and its associated mental states.
This session shifts from the 14Hz sensormotor rhythm through beta to 40Hz gamma, and repeats the pattern over and over, constantly “revving up”the mind with each repetition. The process is stabilized with a 10Hz background alpha beat, allowing the brain a place to relax instantly, whenever a let up allows. Use this session any time, and for as long as required to get the job done. Take in a High Energy Espresso on long-hauls for a welcome lift. Works without headphones, but the best benefits can be found with them. The session finishes at a fast, revving 18Hz beta. For use mainly with eyes open, engaged in activity - with benefit to be gained from periodically closing your eyes briefly and relaxing.
