Origin
This expression is based on long-standing empirical observations that the human body and mind are closely connected. It describes how persistent worry or anxiety can weaken the immune system and make one more susceptible to illness, while a strong belief in recovery can speed up the healing process. Modern medical concepts such as psychosomatic medicine and the placebo effect can be cited as scientific validation for this principle.
