By; Dr Sajid Ali Talpur

2. In order to produce the excitatory effects of the music the body needs to release
various substances like serotonin. Due to the prolonged listening the body can not
compensate to produce these substances at a rapid rate they are depleted such
that it leads to depression. This is the reason we give people of depression the
drugs like SSRI(selective serotonin reuptake inhibitors) which instead of
generating prolong the action of the preexisting agents.
