Binaural beats can be used by most people with no risk of any harmful side effects, however there are specific issues where caution is required when using this technology.
Seizures & Mental Illness: People with an existing medical history of mental illness or epilepsy should not use binaural beats due to the risk that the process of entrainment can trigger seizures. It is also not recommended to use this therapy with children as they can be more prone to seizures even when there is no previous history of epilepsy.
Pregnancy: Binaural beats are not recommended for children for reasons given above and the same advice and considerations should apply to the un-born baby. It is very unlikely that binaural beats would cause any ill effects to a pregnancy but it is advisable to be cautious and avoid to brainwave entrainment at this time.
Heart Problems: Changing brainwave patterns can affect the rhythm of your breathing and heartbeat. This is usually beneficial and therapeutic but anyone who has irregular heartbeats or a pacemaker should get medical advice before using binaural beats.
Operating Machinery: Binaural beats, in common with other therapies such as hypnosis and meditation, can bring about a deeply relaxed, hypnotic mind state. It should therefore never be used whilst driving or operating machinery or when undertaking any vital task that needs close attention.
