What is Alpha State?
Alpha state refers to a specific pattern of brain activity characterized by electrical oscillations in the 8–12 Hz frequency range, measurable through electroencephalography (EEG). This state occurs when a person is both relaxed and awake, representing what neuroscientists describe as a balance between active focus and deep rest. Unlike the higher-frequency beta waves associated with active thinking or the slower theta waves of drowsiness, alpha represents a distinctive middle ground—conscious but not striving, present but not engaged in effortful mental work.
Alpha waves are seen predominantly when a person is awake but relaxed, especially with eyes closed. The state manifests during daydreaming, meditating, or the serene moments just after waking up, as well as during routine tasks like pottering in the garden, taking a shower, putting on makeup, doing light housework. Practitioners and researchers sometimes refer to alpha as the bridge between the conscious mind and the subconscious mind.
The alpha state is not merely an absence of mental activity. Historically, alpha waves were interpreted as an “idling rhythm,” reflecting cortical inactivity, based on observations that alpha activity increases during rest and decreases with sensory stimulation, but contemporary research recognizes alpha waves as an active mechanism in brain processing, involved in the inhibition and gating of sensory information. Current neuroscience understands alpha oscillations as playing a central role in sensory gating, attention, and working memory.
Origins & Lineage
On July 6, 1924, German psychiatrist Hans Berger first recorded electric signals from the human brain via scalp electrodes, marking the beginning of electroencephalography. Berger spent five years refining his technique in secret before publishing his first paper in 1929, fearing ridicule from the scientific establishment. He published the first report of the human EEG in 1929 and described the terms “alpha waves” and “beta waves” and the abolishment of alpha with the eyes open.
Berger is best known as the inventor of electroencephalography in 1924 and as the discoverer of the alpha wave rhythm, which has been eponymously referred to as the “Berger wave”. From 1930 onwards, the ‘large amplitude, first-order waves’ with a frequency of between 8 and 11 Hz were termed alpha, whereas smaller amplitude waves of higher frequencies were termed beta. Hans Berger in 1929 found that alpha power increases during eyes closed especially at rest and decreases with eyes open (the “Berger effect”).
Initially, Berger’s findings met with skepticism in German medical-scientific circles, but by the end of the 1930s his achievements were widely accepted, thanks to reproductions of EEG recordings by Lord E. Adrian (Nobel laureate in 1932), who stressed that alpha waves were called Berger waves.
The modern conception of alpha state as a trainable, therapeutically useful condition emerged in the 1960s. One of the first neurofeedback experiments was conducted in the late 1960s by Joe Kamiya at the University of Chicago. Kamiya found that by using a simple reward system, people could control their brain waves; he trained people to achieve an alpha state by rewarding them with the sound of a bell, the first time real-time feedback was given to humans based on their EEG monitoring. Kamiya focused on training alpha waves that created a relaxed, meditative state in patients, leading some subjects to have transcendental experiences, and this ability to relax the brain caused media frenzy in the late 60s.
By 1975, an individual interested in purchasing an alpha monitor had at least 16 options from which to choose, reflecting the rapid commercialization of alpha biofeedback technology during the 1970s.
How It’s Practiced
Alpha state can be accessed through multiple pathways, both traditional and technological. Meditation remains the most widely practiced method. Research shows that regular meditation rewires the brain to enter the alpha state more easily. Studies show that meditation can change brain activity, with alpha waves increasing in the back and moving forward with practice.
Gentle physical activities such as yoga, tai chi, or even nature walks can stimulate alpha waves. Simple behavioral interventions also trigger alpha production: alpha power increases during eyes closed especially at rest, making eyes-closed relaxation one of the most accessible entry points.
Technological approaches include neurofeedback training, where subjects observe and ultimately gain volitional control over their own brain activity through recording of neural activity, extraction of neural features of interest, transformation of these features, and feeding the resulting signal back via visual, auditory or tactile modalities. These simple EEG apparatuses provide audible feedback when a user’s brain produces alpha waves, thus reinforcing the frequency and providing a form of technologically-guided meditation.
Contemporary alpha training protocols vary in sophistication. In thirty-minute sessions, eyes-closed, practitioners feed the brain information about its own state—whether it is in alpha or theta state—and the brain inevitably chooses to slowly oscillate between meditative alpha and more dream-like theta. Some protocols combine alpha training with guided imagery to address and process more complex, specific issues.
Binaural beats represent another technological method. Binaural beats are a great way to use brainwave entrainment to promote alpha brain waves, though isochronic tones are a single frequency that can be listened to with speakers, unlike binaural beats which require headphones.
The Silva Method is a mixture of meditation techniques and exercises developed by Jose Silva in the 1940s, now translated and taught across the world, designed to help people get into the alpha state and improve their creativity and intuition.
Alpha State Today
Alpha state has moved from laboratory curiosity to mainstream wellness practice. Contemporary seekers encounter alpha training through multiple channels: consumer EEG devices, meditation apps with real-time feedback, clinical neurofeedback programs, and traditional meditation instruction that implicitly cultivates alpha-dominant states.
EEG technology has improved, making brain monitoring easier and more affordable; biofeedback tools are now small, simple, and available for home use, using EEG sensors to measure brain activity and showing different wave patterns, helping users control and stay in the alpha state meditation. The Muse S meditation headband costs $249 and offers real-time feedback; Flowtime, priced at $199, combines EEG monitoring with guided meditations and personalized training.
Clinical applications have expanded beyond the original stress-reduction focus. Methods like transcranial alternating current stimulation (tACS) and neurofeedback training can increase alpha waves, which might help with symptoms of major depressive disorder and generalized anxiety disorder. Alpha-neurofeedback is a novel therapy which trains individuals to volitionally increase their alpha power to improve pain.
Research continues to refine understanding of alpha’s role in learning and cognition. A recent study showed that electrical oscillations in the alpha frequency band are able to predict up to 64% of the observed variability in the learning outcome in a perceptual task.
Common Misconceptions
Alpha state is not a mystical frequency or universal panacea. The 1970s popularization of alpha biofeedback led to inflated claims that damaged the field’s credibility. Some saw neurofeedback as a panacea to treat stress, but with opposition from vested interests and seemingly incredible claims by some proponents, academic funding dried up.
Alpha is not synonymous with meditation or relaxation itself—it is one measurable correlate of certain mental states. Not all meditation produces increased alpha; different practices generate different brainwave signatures. Studies involving clinical populations reported no differences in alpha power with eyes closed while attending to auditory clicks, with a time production task, and with an eyes-open session watching a video, though one study found lower levels of alpha compared to a problem-solving task.
The “alpha blockade” phenomenon—the suppression (substitution by faster beta waves) when the subject opens the eyes—means that alpha naturally diminishes during visual engagement and active thinking. This is normal brain function, not a failure to maintain a meditative state.
Alpha waves were historically interpreted as an “idling rhythm”, but this passive characterization has been superseded. Alpha reflects active neural processes of sensory inhibition and attention control, not mental vacancy.
Finally, alpha training efficacy remains debated. Although the first experiments on alpha-neurofeedback date back nearly six decades, the effectiveness of this paradigm in various experimental and clinical settings is still a matter of debate. Alpha power was overall higher during upregulation compared to downregulation training during training itself, but there appeared to be no “offline” transfer as measured during resting-state recording post-training.
How to Begin
The most accessible entry point requires no technology: close your eyes and rest in a quiet environment for 5–10 minutes. This simple practice naturally increases alpha activity for most people.
For structured guidance, mindfulness meditation instruction (available through local meditation centers, apps like Calm or Insight Timer, or teachers in the Vipassana or Zen traditions) provides systematic training in the attentive relaxation that correlates with alpha states.
The Silva Method is designed to help people get into the alpha state and improve their creativity and intuition, offering workshops and courses for those interested in a structured alpha-focused program.
Consumer neurofeedback devices offer real-time feedback for those drawn to technological approaches, though the scientific support for home devices is less robust than for clinical neurofeedback protocols. Clinical neurofeedback practitioners (locatable through the International Society for Neuroregulation and Research or the Biofeedback Certification International Alliance) can provide professionally supervised alpha training.
For historical and scientific context, Kamiya’s 1971 paper “Operant Control of the EEG Alpha Rhythm and Some of its Reported Effects on Consciousness” (in Biofeedback and Self-Control: an Aldine Reader) remains foundational, though primary research papers assume technical background in neurophysiology.
