At present, I am pregnant for 30 weeks, and I see many expectant mothers discussing the pain relief of musical instruments in the mother group. What is the analgesic principle of musical instruments?

Daole Musical Instrument is an original three-way analgesia method, with multi-point synchronous output. It can rapidly induce nerve fiber conduction aiming at the trigger points of pain portal, radial nerve and median nerve of spinal cord, promote the rapid release of a large number of endogenous opioid peptides (EOP) and block the transmission of pain information. In other words, musical instruments actually stimulate the human body's own analgesic system by means of electric current, and at the same time block the information transmission of pain to the brain, so that people can't feel pain in the brain, so musical instruments are harmless to the body.
