Often "disco dancing" is harmful to health, prone to tinnitus, persistent low-grade fever, cough and other symptoms, inducing limb tremor. The main symptom is that the patient's legs and head always shake involuntarily whether sitting or standing. Disco dancing is the chief culprit of neurological diseases. Teenagers are in the period of growth and development, and they are often exposed to deafening music and dazzling lights, which will do great harm to their health. Being in such an environment for a long time will also lead to neurological disorders in the brain, insomnia and dreaminess, memory loss and headache.
