Binaural beats for anxiety: alpha beats for relaxation and stress relief

Do binaural beats help with anxiety

The clearest test is a moment when almost everyone is anxious: waiting for an operation. In a hospital in the United Kingdom patients waiting for day surgery were randomly split into three groups. One listened to a recording with binaural beats, the second to the same recording without them, and the third received no intervention. Anxiety was measured with a standard questionnaire.

Anxiety fell by 26.3% in the binaural group, by 11.1% in the group with plain audio and by 3.8% in the group without sound. The difference between the first two groups matters most: the same music, the same headphones, and more than twice the effect with the beats.

A meta-analysis of 22 studies later confirmed the picture: binaural beats reduce anxiety, and the overall effect across anxiety, attention, memory and pain is medium in size.

At the dentist and in the emergency department

Two more studies were done where anxiety is part of the day. In Turkey 60 patients waited for the removal of an impacted wisdom tooth. After the anaesthetic was given, half of them listened for ten minutes to tones of 200 Hz in one ear and 209.3 Hz in the other, a 9.3 Hz alpha beat. Their anxiety fell significantly; in the group that simply waited it did not change.

In an emergency department in Australia 170 patients listened for 20 minutes to one of several soundtracks made for the study, among them a composition with an embedded binaural beat. Anxiety fell by 10 to 15% with the sound compositions. This study shows something worth remembering: a well-made, quiet sound calms by itself, and the beat is an addition to it, not the whole effect.

Binaural beats anxiety frequency: which one to choose

Studies on anxiety used alpha, theta and delta beats. Choose by the moment of the day.

Avoid beta and gamma beats when you are tense. They are made for alertness and can make restlessness worse.

Binaural beats for stress relief: a 10-minute routine

In the dental study ten minutes were enough. This routine fits into a break at work or the time before a meeting.

• Sit down, put on headphones, set the timer to 10 minutes and start the 10 Hz alpha beat at a low volume.
• Close your eyes. Breathe in through the nose for a count of four and out for a count of six. A longer out-breath slows the heart.
• Relax the jaw, the shoulders and the hands, in that order. Tension hides there first.
• When thoughts return to the problem, do not argue with them. Go back to counting the breath and to the pulse of the sound.
• When the sound fades out, stay seated for a minute before you stand up.

Before an exam, an interview, a flight or a procedure

The studies have one thing in common: people listened shortly before the stressful event, not days in advance. The same timing works in everyday life.

Before an exam do not use theta or delta. They calm deeply, and you need a clear head afterwards.

What relaxation with binaural beats feels like

People expect a dramatic change and miss the real one. The usual signs are small: the breath becomes slower by itself, the shoulders drop, the jaw unclenches, thoughts still come but stick less.

Some people feel a light heaviness in the limbs or lose track of time. A few feel nothing the first time. Give it three or four sessions before you decide, and judge by how you feel in the hour afterwards, not during the sound.

Binaural beats for deep relaxation: what happens in the body

Relaxation can be measured. The variation of the heart rate shows which part of the nervous system is in charge: the sympathetic part, which prepares the body for action, or the parasympathetic part, which slows it down.

In a double-blind study 21 young adults exercised for 20 minutes and then rested for 20 minutes with headphones, once with theta binaural beats and once with a placebo sound. With the beats parasympathetic activity was higher, sympathetic activity lower, and people reported deeper relaxation. By the end of the rest period the two conditions no longer differed, which suggests that the beats speed up calming down instead of creating a state you would not reach otherwise.

That is a useful way to think about them: a shortcut to a calm you are capable of anyway.

Listening every day: what longer studies found

Two small studies followed people for weeks. In Montreal 15 mildly anxious patients listened to tapes with delta and theta beats at home for four weeks, about two times a week for 30 minutes. The anxiety they recorded in their diaries before and after each session fell significantly. Scores on the standard anxiety questionnaire also moved down, but that change was not statistically significant.

In Oregon eight healthy adults listened to delta beats every day for 60 days. Trait anxiety, the general tendency to be anxious, decreased, and quality of life scores increased. The study had no control group, so it shows a direction, not proof.

Both studies are small. They agree with the larger ones on one point: the effect is felt right after listening, and regular use does no harm.

Binaural beats for pain and headache

Pain and tension feed each other, so the question is natural. In a crossover study in the United States 36 adults with chronic pain listened to a 6 Hz theta beat for 20 minutes a day for 14 days, and to a plain 300 Hz tone for another 14 days. Perceived pain severity fell with the beat, and the effect was large compared with the plain tone.

The meta-analysis of 22 studies also found that binaural beats reduce the perception of pain.

For headache and migraine specifically there are no good studies yet. A quiet theta beat in a dark room may help you rest, but a new, severe or frequent headache is a reason to see a doctor, not to change the frequency.

Binaural beats for anxiety and 432 Hz

432 Hz is often mentioned next to anxiety, and it is a different thing from a beat. It is a tuning: music in which the note A is set to 432 Hz instead of the standard 440 Hz.

One double-blind pilot study compared them. Thirty-three volunteers listened to the same film music for 20 minutes on two days, once tuned to 440 Hz and once to 432 Hz. With 432 Hz the heart rate was lower by almost five beats a minute, and people felt more satisfied and more focused on the music. Blood pressure and breathing rate moved slightly in the same direction without reaching significance.

You can combine the two. Set the carrier of the generator to 216 Hz, an octave below 432 Hz, and the beat to 10 Hz.

Binaural beats for depression and panic attacks

People search for both, and the evidence does not support either as a treatment. There are no controlled trials showing that binaural beats relieve depression, and none on panic attacks.

During a panic attack sound is of little use: the body needs slower breathing and a sense of safety first. Afterwards a quiet alpha beat can help the nervous system settle.

If anxiety or low mood lasts for weeks, disturbs sleep or work, or comes with thoughts of self-harm, talk to a doctor or a psychotherapist. Binaural beats can accompany treatment; they cannot replace it.

Binaural beats for anxiety and sleep

When tension keeps you awake, use two steps: ten minutes of the alpha beat while you are still sitting up, then a 2 Hz delta beat in bed with a 30-minute timer.
