What are Alpha Waves?
Alpha waves are electrical brain activity in the 8 to 12 Hz range. They dominate when you’re awake but relaxed — for example after meditation, while daydreaming, or in those moments just before falling asleep.
They were first measured in 1929 by Hans Berger and were the very first brainwaves ever discovered.
Why are Alpha Waves so Important?
In the alpha state, several things happen:
- Cortisol drops: The stress hormone is reduced
- Parasympathetic activation: The nervous system shifts to recovery mode
- Creativity increases: Alpha waves are associated with creative thinking and problem-solving
- Heart rate variability improves: A marker for resilience and recovery
The problem: In a stressful daily routine, many people struggle to reach the alpha state. The brain stays in beta mode (13–30 Hz) — the mode for concentration, but also for stress and overstimulation.
How BE LIGHT Activates Alpha Waves
BE LIGHT uses the principle of Brainwave Entrainment: External rhythmic stimuli — sound frequencies through headphones and light pulses via the display — synchronize brainwaves to the target frequency.
For relaxation, this means: The session plays frequencies in the alpha range (8–12 Hz). The brain follows this signal automatically — a passive process that requires no practice or concentration.
The Flow of an Alpha Session:
- Minute 1–2: Frequencies start in the beta range and gently guide the brain down
- Minute 3–5: The target frequency in the alpha range is reached, the nervous system begins to shift
- Minute 6–8: Deep alpha activity, noticeable relaxation, cortisol drops
What the Research Says
Studies show consistent results:
- Thut et al. (2011) confirmed that rhythmic stimulation significantly increases alpha activity
- Klimesch (1999) demonstrated the connection between alpha waves and cognitive performance
- Basar et al. (2001) documented the role of alpha waves in memory and attention
Conclusion
Alpha waves aren’t an esoteric concept — they’re measurable brain activity that has been researched for nearly 100 years. BE LIGHT makes it simple to reach this state deliberately. 8 minutes, headphones on, done.
