The exact physiological mechanisms to explain how exercise improves stress have not been delineated. Human and animal research indicates that being physically active improves the way the body handles stress because of changes in the hormone responses, and that exercise affects neurotransmitters in the brain such as dopamine and serotonin that affect mood and behaviors (9,11). In addition to the possible physiological mechanisms, there also is the possibility that exercise serves as a time-out or break from one’s stressors. A study that tested the time-out hypothesis used a protocol that had participants exercise but did not allow a break from stress during the exercise session (5). Participants were college-aged women who reported that studying was their biggest stressor. Self-report of stress and anxiety symptoms was assessed with a standard questionnaire before and after four conditions over 4 days. The conditions were quiet rest, study, exercise, and studying while exercising. These conditions were counterbalanced across participants, and each condition was 40 minutes in duration. The “exercise only” condition had the greatest calming effect (5). When participants were not given a break from their stressor in the “studying while exercising” condition, exercise did not have the same calming effect.
Listen to the gentle rain fall as this brainwave MP3 ramps slowly down to the deepest Delta levels. This is one of the deepest brainwave entrainment meditations you will find. Many people using this session will fall asleep, since it resembles the sleep induction sessions. It differs from sleep induction in that there is an upward ramp at the end to help bring you out of the Delta state before the MP3 is completed. Delta Meditation with rain can be listened to with speakers or headphones.

The phenomena of brainwave entrainment was first described in the scientific literature in 1973 by Gerald Oster in results published in an article in Scientific American entitled, “Auditory Beats in the Brain”. He showed that a specific brainwave could be induced when a person heard two separate, but closely related, sound frequencies, one in each ear. He discovered that when the frequencies heard by each ear differed by about 10 hertz, the brainwave pattern of the person hearing the sound would synchronize to the difference between the two frequencies. For example, if the person heard a 410 hertz sound in one ear and a 400 hertz sound in the other ear, their brainwaves would stabilize at the difference between the two, or 10 hertz. This technique is called binaural beats, and it is a fundamental principle of brainwave entrainment methods.
Anabel first called on Alakazam in Talking a Good Game! to help her and Ash when they were attacked by Team Rocket. Alakazam was able to beat them with its powerful Psychic attacks. Ash then realized that Anabel was a Frontier Brain and that he would have to battle Alakazam. Ash chose Corphish for the match. Anabel had the ability to telepathically communicate with her Pokémon and give commands without saying a word. In the end, Alakazam easily defeated Corphish. Alakazam then went on to defeat Ash's Tauros before finally being defeated by his Pikachu, but not before weakening it.
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.
