When we are mentally active various groups of neurons will be firing and the EEG will look like a jumble of different waves at different frequencies. When we are in a relaxed state, however, our brains settle into a steady rhythm – when fully awake this is the alpha rhythm, which as a frequency of 8-12 hz and other recognizable features. When drowsy our brainwaves slow to the theta range, 6-7hz, and when in deep sleep into the delta range, 4-5hz.
There are five main categories of brainwave frequencies: Gamma (40Hz+), Beta (13 – 40Hz), Alpha (7 – 13Hz), Theta (4 – 7Hz), and Delta (<4Hz). Each category is associated with a different state of mind; so, for example, when you’re in a peak state of performance, your brain produces Alpha Waves, and when you’re in a deep sleep, your brain produces Delta Waves.
According to an American Psychological Association (APA) survey, more women than men (one in three) turn to comfort food such as ice cream and cookies to ease stress. It's common for women to deny themselves favorite foods because they're trying to lose weight. But under stress, the urge for them becomes even stronger. In fact, researchers at Montclair State University in New Jersey recently confirmed that dieters are more likely than non-dieters to overeat when under pressure, bingeing on the very same high-fat foods they normally try to avoid. The key is to not deprive yourself. Keep three or four healthy snacks on hand that you know you'll probably want--peanuts, if you like salty; string cheese, if you crave protein; a small piece of chocolate for something sweet--so you aren't tempted to binge.
According to a recent study published in the British journal Heart, slow or meditative music is a proven stress buster, so set your dial to a soothing station during your commute. And, if you're stuck in a traffic jam, sneak in this quick exercise: Grab your steering wheel and clench the muscles in your fingers, arms, shoulders and back. Do this until your muscles begin to tremble (about 45 seconds), then release. You'll produce a wave of relief in your upper neck and arms all the way down to your fingers. Just make sure your foot is on the brake when you let go of the wheel! (FYI: pink noise is the newest tool for reducing stress.)
From a brainwave entrainment effectiveness perspective, it’s my understanding that the response from isochronic tones stimulation starts to diminish over 30Hz and that 40Hz is about the limit for using them. So from what I’ve read on the topic a 100Hz beat wouldn’t work, probably because it’s too fast for the brain to process and synchronise with it.
Hi Et, In all the feedback and studies I’ve read and looked into over the years, I’ve seen lots of feedback from people talking about how they don’t like the sound of the tones, or they find them irritating in some way. Unfortunately, there doesn’t seem to be any particular reason why one person likes it and the next doesn’t. It’s a bit like normal music, one person’s sweet symphony is another person pneumatic drill. It’s common for people to find it weird and maybe annoying at first, which is how I felt in the beginning. But usually after a few listens you can start to get used to it and appreciate the sound, and especially the feeling it gives you. Personally, I think it can help if you try to embrace the sound, psychologically speaking beforehand. It can also help to have the sound playing at a very low volume, to begin with, then building it up as you get more used to it.
Respectfully ask others to change their behavior. And be willing to do the same. Small problems often create larger ones if they aren't resolved. If you're tired of being the target of a friend's jokes at parties, ask him or her to leave you out of the comedy routine. In return, be willing to enjoy his or her other jokes and thank him or her for humoring you.
However, with this integration will come upheavals as the mind is forced to integrate areas of the brain that were previously sequestered. Repressed memories and unpleasant emotions from the past will often rise to the surface of the mind to be processed and healed. This is sometimes referred to as "processing the shadow" within one's mind and emotions.
The studies included in the recent reviews of Tai Chi and yoga indicate that sessions between 60 and 90 minutes performed 2 to 3 days per week were effective in reducing stress and improving feelings of well-being (7,14,17). A study conducted in a worksite environment showed that 15 minutes of chair-based yoga postures was effective in reducing acute stress when assessed by self-report and with physiological measures (e.g., respiration rate and heart rate variability parameters). This finding indicates that shorter duration sessions can be effective in reducing acute stress with this type of exercise (15).
Gamma brainwaves occur during creative thinking and processing of memory and language and in many learning activities. These brainwaves are not present at all when a person is under anesthesia, but return as soon as the person becomes conscious again. Multiple scientific studies have shown gamma brainwave entrainment to be helpful for reducing distractibility, improving short-term memory, improving motor coordination, and relieving migraine headaches.
Binaural beats must be listened to using headphones. You definitely should not use them while driving or operating heavy machinery as you will be in an altered state of mind. Brainwave entrainment is a form of meditation and designed to be very passive, in fact, all you need to do is sit back, put on your headphones and let the technology do the work for you. It is best to find a session that you find soothing to listen to, as binaural beats on their own are a very strange sound that can be disturbing to some listeners. This was actually what inspired me to invent Trypnaural as a way for brainwave entrainment to be more bearable to listen to for long periods of time.

Another common misconception is that entrainment is going to force your brain into doing something beyond its native capabilities, or at least beyond what it is accustomed to doing. This mistaken belief is often the root that leads to comments like, “When I meditate with LifeFlow my face gets flushed (or my hair vibrates or I develop x-ray vision, or any of the other things we come across). If I meditate without LifeFlow the face flushing doesn’t happen. LifeFlow must be causing it.”
Stress can either be perceived as feeling good/positive or bad/negative depending on the context, and the body reacts differently to both kinds. However, where the body isn’t so clever is distinguishing between very serious threats (like being robbed or starved) and events that are stressful but not actually life-threatening. Unfortunately, whether a problem is very serious or not, the body usually has no way of knowing the difference− — anything that causes you to worry, anticipate, regret, overthink or panic can send your stress levels through the roof.
The I-Doser claims it can emulate prescription drug-like effects by listening to MP3's, to get stoned. This is largely a moral panic by parents who flunked science fueled by the eternal quest by teenagers to get stoned, and stupid ones convincing their friends it works. It is really more of wishful thinking and making yourself disoriented by playing discordant sounds really damn loud. If you want to experience it yourself, you can always listen to Bjork Captain Beefheart dubstep.
Participants in the included studies were children and adults, either healthy or with conditions such as learning disabilities, attention deficit hyperactivity disorder, migraine, stress, anxiety and myofascial pain. Interventions included single, alternating, ascending or descending frequencies of photic or auditory stimulation or audiovisual entrainment selected either by the participant or by the investigator. Nearly half the studies used single sessions and the rest used multiple sessions ranging from nine to 100. Length of session varied from 0.5 seconds to 60 minutes. Frequency of session varied from twice daily to weekly. Outcomes reported in the review included cognition (including verbal skills, performance skills, attention, memory and overall intelligence/achievement), short- and long-term stress, pain, headache/migraine, mood, behavioural problems and premenstrual syndrome (PMS).
