Worry and
Exhaustion
Q. Why does worry cause exhaustion and depression?
A. Worry is a sort of mental short-circuiting which
rapidly exhausts the nerve centers, draining them of their energy and unfitting
the body for useful effort. Experiments have demonstrated that depressing
emotions are far more powerful causes of wear
and tear to nerve centers than is healthy brain work.
According to Mosso's observations, the
effect of vigorous intellectual activity upon the brain is far less than that
of a disturbing emotion. Mental work, combined with worry and anxiety, tears down the nerve centers, exhausts their
stores of energy, and cripples their ability to
recuperate; but it is not the work itself which does the mischief; it is the cross-fire, the
short circuit, the confusing and harassing influence of disturbing emotions,
which exhaust the nerve forces and prevent the brain from repairing its losses.
