Isochronic tones work just the same in delta as they do in alpha, theta and beta and they are widely used in the brainwave entrainment community to help people sleep. Like you, I’ve also seen some websites saying they don’t work in delta, but it’s a bit like the game of Chinese Whispers, where someone makes a comment and then after it gets passed around and shared a lot the message gets distorted and appears to be a fact. I don’t know of any scientific reason why they wouldn’t work in delta. I remember some people talking about this on a brainwave entrainment forum many years ago. They were saying they found isochronic tones a bit too abrupt for using to help them sleep and they preferred binaural beats, as they thought they were a more soothing sound. That was just a personal preference shared by a couple of prominent forum members at the time and some people then took that as a fact for everyone. That’s where I think that belief originated from.
You know how movie characters always look themselves in the restroom mirror when faced with a tough situation? Well, giving yourself a quick pep talk in the looking glass can actually help relieve stress. “‘Mirror work‘ is done by looking in a mirror and vocally speaking positive affirmations to yourself with affectionate conviction, to release worry or to improve your self-confidence,” Whitaker says. To relieve stress in the moment, she suggests using a restroom mirror, your car’s rear-view mirror, or even a compact. “Calm your mind by saying encouraging affirmations aloud to yourself, such as, ‘I am excellent at what I do,’ ‘I’ve got this! I am amazing,’ ‘I am an asset to this company,’ or ‘I am awesome!’” she says.
When combined with the right diet and exercise, progesterone cream and herbal products can help you balance your hormones and get through menopause without the life-disrupting side-effects. Just remember, all of these techniques work together. A few herbs aren’t going to overcome a bad diet and sedentary lifestyle. Your body wants to move and be active. Support it by using proper nutrition and proper exercise. Then add the herbs to give you the last little boost to make sure everything is balanced and healthy.
When work deadlines begin piling up and your social calendar is booked, the last thing you want to hear is to steer clear of the vending machine. Who has time for healthy eating? But when it comes to combating stress levels, what you eat may actually help relieve your tension. Indeed, some foods may help stabilize blood sugar or, better yet, your emotional response. Here, 12 foods to reach for when you've just about had enough.
Tennis, anyone? One of the best ways to fit exercise into your schedule is to round up friends and family and organize a game of football, basketball, or soccer — just three of many choices. You get a double dose of stress relief from participating in team sports: Not only are you having fun with loved ones, but you’re also working up a sweat and releasing endorphins. Exercising with friends or co-workers can also motivate you to push yourself a little harder in order to stay competitive.

It's tempting to reach for a cheeseburger when stressed, but go green at lunch instead. "Green leafy vegetables like spinach contain folate, which produces dopamine, a pleasure-inducing brain chemical, helping you keep calm," says Heather Mangieri, RDN, a spokesperson for the Academy of Nutrition and Dietetics. A 2012 study in the Journal of Affective Disorders of 2,800 middle-aged and elderly people and found those who consumed the most folate had a lower risk of depression symptoms than those who took in the least. And, a 2013 study from the University of Otago found that college students tended to feel calmer, happier, and more energetic on days they ate more fruits and veggies. It can be hard to tell which came first—upbeat thoughts or healthy eating—but the researchers found that healthy eating seemed to predict a positive mood the next day.
Anabel debuts in the Emerald chapter. She is one of the seven Trainers hired by Scott to be a Frontier Brain at the Battle Frontier. Anabel is first seen watching the Battle Frontier's opening ceremony. The ceremony is interrupted by Emerald, who announces that he wishes to conquer the Battle Frontier. The press mistakenly report the incident as allowing an ordinary Trainer to take part in the Battle Frontier before it officially opens a week later. The Frontier Brains decide to use this assumption as free publicity and allow Emerald to challenge the Battle Frontier under the condition that he completes it before it officially opens.
I have seen 1.5Hz being linked to HGH, but also 4 or 5 other frequencies as well, so it’s difficult to know what may work if any. I haven’t seen any research relating to HGH and brainwave entrainment. It’s widely believed that 40Hz is the limit for achieving a brainwave entrainment effect, which is also where many believe the gamma frequency range begins. Once you get over 40Hz into gamma your brainwave activity isn’t likely to stay in sync with it. So from a brainwave entrainment perspective, I recommend high beta frequencies for increasing energy during workouts.
With each pulsed tone, the brain produces an electrical response. The effects one experiences are the creations of the brains reaction to the “tones”, what neurologists call the “cortical evoked response” (the electrical response of the top most cortical layer of the brain). The brain is a mass of neurons, each taking part in storing, retrieving and transmitting electro-chemical impulses: information, colors, images, sounds, smells and tastes. Brainwave entrainment stimulates different areas of the brain allowing for the awakening and subsequent release of various levels of stored material. It also has an effect of  quietening the mind for clearer thought and process.
Applying brainwave entrainment in the alpha range may result in benefits similarly found with Zen or Transcendental Meditation. These benefits extend throughout the body and include improved breathing patterns, higher physical energy levels, an improved outlook, increased sports performance, improved relationships, and increased workplace satisfaction and performance … just to name a few.
Although there is a general stress response pattern, there can be variations in the response according to the characteristics of the stressor (10). Individuals tend to respond differently based on the familiarity of the stressor. For example, the perceived level of stress and physiological response when giving a presentation to a group of work colleagues will likely be less than when presenting to an unfamiliar group. The stress response also varies depending on the level of perceived control one has over the stressor (10). If there is a way for one to actively cope with the stressor that is reasonable, then the individual usually perceives more control over the situation. Consider an individual who has to take a certification examination for work and has 6 months to prepare. He can adjust his schedule to accommodate study time. However, waiting for medical test results that show whether one has a serious illness does not allow a sense of control over the stressor, and the individual passively endures the stressor or may try to avoid the stressor. With this uncontrollable type of stressor, there is a more negative reaction with greater productions of cortisol, which can have damaging health effects because of the suppression of immune function (10).

Binaural beats are created from two different continuous tones, which when sent separately to each ear create a single beat inside your head. Isochronic tones are basically a single tone which is switched on and off at regular intervals. Imagine a single continuous tone playing on a stereo system and you’ve got your hand on the volume switch. Then once per second, you turn the volume off for half a second and keep doing that every second. For half a second the volume is off, for the other half a beat waveform is formed. The beat is cycling once per second per second, i.e. at a rate of 1Hz.

Robert Monroe, a radio producer and executive published a popular book called Journeys Out of the Body about his out-of-body experiences when using brainwave entrainment. He later founded an original brainwave entrainment audio company, Hemi Sync. In 1981, the book Mega Brain by Michael Hutchison brought brainwave entrainment information, techniques, and terminology into the popular press.
While people have full control of themselves when they are conscious, it’s a whole different ballgame when it comes to dealing with their subconscious. However, with regular production of Theta brainwaves, you’re able to eliminate any emotional blockages you may have, allowing you to accept suggestions and ideas more, helping you re-program your brain to suit your needs.

When the brain is stimulated with pulsed sounds (neuro-electrical activity via the nerves originating from the ears), the overall activity of the brain will respond to and align with these pulses. By selecting the desired rate, the brain — via the frequency following response (entrainment) — can be naturally induced towards the selected brainwave state.
Another study found slight improvements in trait anxiety as a result of entrainment. It was noted that the study with the most successful protocol started at 30 Hz beta and ramped the frequency down until the person experienced relaxation for 15 minutes. This was then followed with a session of 8 Hz to 14 Hz for 7 minutes. The results suggested that 75% of individuals improved on their measures of long-term stress.
I can’t thank you guys enough for saving my life. I tell everybody I know about your guys. I love you guys. I word of mouth advertise and give my testimony to the power of your technology almost everyday. I am only 30 years old, but since I was 17 teen years old my life was a miserable roller coaster ride. I ended up being diagnosed with fibromyalsia, bipolar disorder, adhd, manic depression, sever anxiety, severe depression, chronic fatigue syndrome, and you name it. Because of your product, I have never felt better in my entire life. I can cope and manage and more. I can finally sleep a full night without tossing and turning waking to knots in my back and stomach. I can finally stand straight and tall without feeling like I have a pinched nerve in my neck. I have energy again, and a renewed passion for life!
In much the same way, Christian fundamentalism is a parasitic ideology that inserts itself into brains, commanding individuals to act and think in a certain way — a rigid way that is intolerant to competing ideas. We know that religious fundamentalism is strongly correlated with what psychologists and neuroscientists call “magical thinking,” which refers to making connections between actions and events when no such connections exist in reality. Without magical thinking, the religion can’t survive, nor can it replicate itself. Another cognitive impairment we see in those with extreme religious views is a greater reliance on intuitive rather than reflective or analytic thought, which frequently leads to incorrect assumptions since intuition is often deceiving or overly simplistic.

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.
