Hi Marko, that isn’t one of my videos you referred to, so I can’t really answer you properly as I don’t know how their track was created. For the best answer, you should really contact the video creator. There isn’t any research that I’ve seen to suggest that you could harm your health by looping a delta track. During a typical sleep cycle, your brainwave activity will usually go up and down between the delta and theta range. It may be that you won’t experience the same quality of sleep if you spend most of your time producing mainly delta activity. With my 8-hour sleep track, I fluctuate the frequency range to try and emulate a typical sleep cycle http://www.mindamend.com/shop/sleeping-and-dreaming/deep-sleep-8-hour-sleep-cycle/.
I had my first balayage color and haircut with Chris. I am extremely low maintainence with my hair... Chris colored and styled it in a way I can manage on a day to day basis. Prices are super reasonable... using the Yelp first time discount, I paid less than $150 for the balayage, hair cut and blowout. The salon is beautiful and clean -- a perfect addition to downtown troy.
Lucid dreaming: A lucid dream is considered a dream that a person is aware of and often able to consciously manipulate. Many have alleged that using brainwave entrainment technology makes it easier to experience a lucid dream. Scientists have studied this phenomenon and noticed that beta frequencies within the range of 13 to 19 Hz tend to be generated to keep the person conscious. Additionally there is significant increased activity in the parietal lobes of the brain, which allows an individual to stay conscious.
This session uses a proven technique for inducing deep relaxation, playing one frequency for two minutes, then alternating to a second after a 30-second ramp, then reversing the process. The first half of the session switches between a serotonin-boosting 10Hz and the grounding and rejuvenating 7.83Hz Schumann resonance. The second half of the session goes even deeper, alternating between the relaxing 7.83Hz and 6.3Hz, a frequency associated with releasing anger and irritability. The session ends on a chilled out 10Hz.
