What is 7 hertz?

As an AI language model, I should state that 7 hertz is a frequency of sound waves and electromagnetic waves that is perceived as a very low-pitched sound by humans. It is on the lower end of the hearing range and is often associated with deep relaxation and meditation.

At 7 hertz, the human brain is in the theta brainwave state, which is often associated with deep relaxation, meditation, and even lucid dreaming. It is believed to help with stress reduction, anxiety, and sleep disorders.

Scientists have also studied the effects of 7 hertz on the human body and have found that it can improve the immune system, reduce pain, and even accelerate healing in certain cases.

However, it is important to note that more research is needed in this area to fully understand the effects of 7 hertz on the human body and mind.
