10 Hz alpha is the brain's natural idle frequency, linked to serotonin release, mood elevation, and relaxed focus. The classic meditation frequency.
Benefits of 10 Hz Frequency
Serotonin release and mood boost
Optimal relaxed focus
Mental clarity
Reduced anxiety and depression
Enhanced mind-body awareness
What Does the Science Say?
10 Hz is the centre of the alpha band and the closest thing the human brain has to a default rhythm. Close your eyes in a quiet room and alpha rises across the posterior cortex within seconds; open them and it drops away. Hans Berger recorded exactly this in 1924 in the first human EEG, which is why alpha is still sometimes called the Berger rhythm. Individual peak alpha frequency sits somewhere between roughly 8 and 12 Hz, varies from person to person, and correlates with some measures of cognitive performance — which is part of why 10 Hz gets singled out. Huang and Charyton's 2008 review of brainwave entrainment found alpha-range protocols among the more consistently reported, though the underlying studies are small and heterogeneous. Claims that 10 Hz raises serotonin specifically are not well supported and are best treated as folklore rather than physiology.
How to Use 10 Hz Frequency
The most versatile alpha frequency. Use for mood enhancement (15 min), relaxation (20 min), or light meditation (30 min). Safe for daily use. Many users report a noticeable mood lift within the first session.
Quick Start Protocol
- Put on stereo headphones (required for binaural beats)
- Open the Free Binaural Beats Generator
- Set the frequency to 10 Hz
- Adjust volume to a comfortable level (lower is better)
- Close your eyes and relax for the recommended session duration

Open Free GeneratorWhat Alpha Actually Is
Alpha is best understood as the rhythm of a cortex that is switched on but not being driven. It is not sleep, and it is not concentration — it is the idling state in between, and the one most people mean when they say they want to relax without switching off.
This makes 10 Hz the most generally useful frequency on the whole site. Delta is for sleep, theta for meditation, beta for work; alpha is for the far more common situation of needing to come down from something without going all the way under.
Session Protocols
Decompression, 15 minutes. After work, after a difficult conversation, after anything that left you wound up. Eyes closed, low volume. This is the highest-value use of 10 Hz and the one that needs no technique at all.
Pre-task calm, 10 minutes. Before something that makes you nervous — a presentation, an exam, a difficult call. The goal is not to get calm and stay there but to lower the baseline you start from. Pair it with slow exhales; our breathing pacer works well underneath.
Reading or light study, 30–45 minutes. Alpha suits absorbing material better than it suits producing work. For analytical output, beta is the right neighbourhood — see the beta guide.
Alpha and Anxiety
Alpha-range binaural beats are the most-studied part of this field for anxiety, and the picture is genuinely encouraging but modest. A 2019 meta-analysis by Garcia-Argibay and colleagues found a small-to-moderate effect on state anxiety — the in-the-moment kind, before a procedure or an exam — which is precisely what an acute intervention would be expected to help with. The evidence for trait anxiety, the persistent disposition, is much weaker.
Read that as: useful for taking the edge off a specific anxious hour, not a treatment for an anxiety disorder. If anxiety is affecting your daily functioning, cognitive behavioural therapy is the first-line intervention with the strongest evidence base, and this is not a substitute for it.

Understanding the Alpha Band
The 10 Hz frequency falls within the Alpha brainwave band (8-14 Hz). Learn more about this entire frequency range and its applications in our complete Alpha frequency guide.
Safety & Recommendations
- Always use stereo headphones for binaural beats to work
- Keep volume at a comfortable level - louder is not better
- Do not use while driving or operating heavy machinery
- Those with epilepsy or seizure disorders should consult a doctor first
- If you experience discomfort, stop listening immediately
- Binaural beats are a wellness tool, not a medical treatment
Frequently Asked Questions
Why is 10 Hz recommended more than any other frequency?
Because alpha is the brain's resting rhythm and 10 Hz sits at its centre, so it is the least specialised and most broadly applicable choice. It is also the range with the most supporting research, thanks largely to the work on state anxiety.
Does 10 Hz increase serotonin?
That claim circulates widely but is not well supported. There is no good evidence that a 10 Hz binaural beat measurably changes serotonin levels. Alpha is associated with a calm, settled state; the neurochemical story attached to it is speculation.
Can I use 10 Hz while working?
For reading, reviewing or absorbing material, yes. For demanding analytical work you generally want beta (14–30 Hz) instead — alpha is a relaxed state, and relaxed is not the same as productive.
How does 10 Hz compare with just closing my eyes?
Closing your eyes in a quiet room already raises alpha substantially — that is the Berger effect. The audio adds a steady anchor for attention and, if entrainment works as the EEG literature suggests, a push in the direction you are already going. It is an assist, not a separate mechanism.
Is 10 Hz safe to use daily?
For healthy adults, yes, at a comfortable volume through stereo headphones. Do not use it while driving. If you have epilepsy or a seizure disorder, are pregnant, or are being treated for a psychiatric condition, check with your doctor first.
