Binaural beats are used for various health and cognitive reasons, yet some people are sceptical about their safety and potential hidden side effects.
So, are binaural beats safe, or are there real dangers? Can binaural beats damage your brain or cause side effects that affect your health long term? This guide covers the risks, the warnings, and who should avoid them.
For the vast majority of healthy adults, binaural beats are safe, and there is no evidence that they cause lasting harm or damage to your brain. However, you shouldn't use binaural beats if you have epilepsy or a history of seizures. Pregnant women and parents of babies or young children should talk to a doctor first, because these groups have not been studied.
Are Binaural Beats Safe to Use?
Binaural beats are safe for the majority of people and can be beneficial. Some people use them to:
fall asleep more easily and battle insomnia;
feel more relaxed and less stressed;
ease the perception of pain;
improve focus and productivity;
boost creativity and imagination.
Some studies into this brainwave entrainment method suggest improvements in creativity, focus and relaxation, although research is still limited and results are mixed. Many people also say binaural beats help them manage stress or break difficult habits.
Therefore, listening to binaural beats is generally safe, and many people find them a useful addition to their routine.
Can Binaural Beats Be Harmful If You Use the Wrong Frequency?
When using binaural beats, the most important thing is to use the correct frequency for the task or habit you are working on.
If you apply a frequency that doesn't match what you are doing (for example, a sleep frequency while trying to focus at work), the beat is unlikely to work effectively, and you may feel drowsy, unfocused or uncomfortable. If that happens, stop and switch to a more suitable frequency.

Binaural Beats Warnings: Who Should Avoid Them?
There is a group of people who shouldn't listen to binaural beats, or who must seek professional advice before using them. Be careful if you:
have epilepsy or a history of seizures;
have a heart condition or a pacemaker;
are pregnant;
want to use them for babies or young children;
take medication for a mental health condition;
are driving or operating machinery.
If you notice any side effects or feel a binaural beat is unsafe for you, stop listening immediately.
Are Binaural Beats Safe for People With Epilepsy?
People who have epilepsy or regularly have seizures should not use binaural beats or other brainwave entrainment methods without medical approval. Binaural beats are designed to influence brainwave activity, and for people who are prone to seizures this could increase the risk.
Always ask your doctor about the risks of sounds or music designed to change brain activity.
Binaural Beats, Heart Conditions and Pacemakers
There is no strong evidence that binaural beats disrupt heart rhythm. Deep relaxation can slightly change your heart rate, which is harmless for most people. However, if you have a heart condition or a pacemaker, it's sensible to check with your cardiologist before using any brainwave entrainment method.
Are Binaural Beats Safe for Babies or Children?
Binaural beats have not been studied in babies and young children, and their brains are still developing. Because of this lack of research, it's best not to use binaural beats with them. A gentler alternative to help babies and children sleep is white noise played through speakers at a low volume.
Are Binaural Beats Safe During Pregnancy?
There is no evidence or documented case showing that listening to binaural beats has induced labour or harmed a baby. However, binaural beats haven't been properly studied in pregnancy, so many experts recommend caution.
Always speak with your healthcare professional before using binaural beats while pregnant.
Are Binaural Beats Safe While Taking Medication?
If you take tranquillisers or other medication for a mental health condition, talk to your doctor before using binaural beats. Brainwave entrainment can affect your mood and state of mind, and it may interact with how you feel on your treatment.
People with serious mental health conditions, such as schizophrenia or bipolar disorder, should only use binaural beats if their health professional approves.
Don't Listen to Binaural Beats While Driving
Never listen to binaural beats while driving, or while carrying or operating heavy machinery. They can change your state of consciousness and make you drowsy or less alert.
For example, relaxation and sleep frequencies can put you into a trance-like state, which could put you or other people in danger in a hands-on, physical environment.
Potential Side Effects of Binaural Beats
Even if none of the warnings above applies to you, there are still some potential binaural beats side effects you should be aware of:
Low mood. Some people report feeling more down or depressed after listening.
Irritability or anger. Short bursts of irritability can happen after a session.
Confusion or anxiety. Some listeners feel disoriented or anxious, especially after long sessions.
Headaches. Often caused by high volume or listening for too long.
Ear discomfort. Loud audio through headphones can strain your hearing.
It's also important to note that binaural beats can't replace conventional therapy. They can complement a treatment plan, but they are not effective enough on their own for certain conditions.
What to Do If You Have a Bad Experience With Binaural Beats
Stop listening straight away and take off your headphones.
Rest in a quiet place and drink some water.
Lower the volume and shorten your sessions if you try again.
Switch to a different frequency or try music without binaural beats.
See a doctor if symptoms are severe or don't go away.
Can Binaural Beats Damage Your Brain?
There is no scientific evidence that binaural beats cause permanent brain damage. The effect of binaural beats is temporary: when you stop listening, your brain returns to its normal activity.
The main real risks are seizures in people who are already prone to them, and hearing damage if you listen at a high volume for long periods. Keeping the volume moderate and following the warnings above removes most of the danger.
Brainwave Entrainment Dangers: Are Other Methods Riskier?
Binaural beats are only one type of brainwave entrainment. Other methods include isochronic tones, monaural beats and light-and-sound machines that use flashing lights.
Methods that use flashing lights carry a higher risk for people with photosensitive epilepsy than audio-only methods like binaural beats. Commercial "brainwave optimization" programmes can also have side effects, most often tiredness, headaches or emotional changes after sessions. As with binaural beats, check with a doctor first if you have any medical condition.
Binaural Beats: Do the Benefits Outweigh the Side Effects?
Now that you know the potential side effects of binaural beats, it's worth weighing up the benefits, so you can make an informed decision about whether you feel comfortable trying the method.
While binaural beats can occasionally worsen mood or trigger anxiety, many people with stress and mild mental health struggles find them helpful, because listening can promote calm and positive emotions.
Other possible benefits include:
More creativity, which is great if you feel stuck in a rut or want to tap into your creative side.
Better focus and concentration, useful if you have exams coming up or a job that requires quick thinking.
Longer attention span and better memory, helping you retain information.
Better sleep. Good quality sleep is essential for your health, so if you struggle in this area, binaural beats can be very helpful.
How Do Binaural Beats Affect the Brain?
For those who don't know, binaural beats are an auditory illusion your brain creates when you listen to two tones at the same time, each with a slightly different frequency, one in each ear.
Your brain perceives a third beat, with a frequency equal to the difference in hertz between the two original tones. For example, a 200 Hz tone in one ear and a 210 Hz tone in the other create a 10 Hz beat.
Your brain activity then tends to follow the frequency of that beat, in a process called the frequency-following response. The goal is to guide you into a certain mental state, such as relaxation, which is why binaural beats are often used in meditation.
How to Use Binaural Beats Safely
Keep the volume low to moderate.
Start with short sessions of 15 to 30 minutes.
Choose the right frequency for your goal.
Listen while sitting or lying down, never while driving.
Stop if you feel dizzy, anxious, or get a headache.
Talk to your doctor first if you have a medical or mental health condition.
