What is Brainwave Entrainment?
Brainwave Entrainment describes the brain’s ability to adjust its electrical activity to external rhythmic stimuli. When you hear a rhythmic tone or see a pulsing light, neurons in the brain begin to synchronize with that frequency.
This phenomenon was first scientifically documented in 1934 by Adrian and Matthews and is known as the Frequency Following Response (FFR).
How does it work?
The brain constantly produces electrical signals — known as brainwaves. These can be categorized into five frequency bands:
- Delta (0.5–4 Hz): Deep sleep and recovery
- Theta (4–8 Hz): Creativity and meditation
- Alpha (8–12 Hz): Relaxation and calm
- Beta (13–30 Hz): Focus and concentration
- Gamma (30–100 Hz): Peak performance and learning
When an external stimulus — such as a binaural beat or light pulse — is presented at a specific frequency, the brain begins to align its own activity to match.
Why does BE LIGHT use Brainwave Entrainment?
BE LIGHT combines sound frequencies with visual light pulses for an amplified effect. Audiovisual stimulation uses two sensory channels simultaneously, which accelerates and intensifies brainwave synchronization.
The result: After just 8 minutes, the nervous system shifts to the desired state — whether relaxation, focus, or flow. No practice, no experience, no concentration needed.
85% of users report a noticeable effect after their first session.
The Research
Brainwave Entrainment is not a new concept. Research spans more than 80 years:
- Chaieb et al. (2015) showed significant reduction in anxiety and stress through binaural beats
- Garcia-Argibay et al. (2019) confirmed positive effects on attention and memory in a meta-analysis
- Abeln et al. (2014) documented improved sleep quality in elite athletes
Conclusion
Brainwave Entrainment is a scientifically validated principle that has been researched for decades. BE LIGHT makes this technology accessible as an 8-minute app — for everyone, everywhere.
