Will dieting or exercising help for depression?
Dieting
Depression is
not caused by problems with diet, although some believe that a balanced
diet would leave one less predisposed to difficulties handling stress and
thus possibly any mood conditions that result from that stress. Problems
with sleep as well are not considered causes of depression but can
predispose someone to depressive symptoms when chronically under rested.
Evidence exists for reduced concentration and irritability in persons
with less then 6 hours of sleep per night. In individuals with manic
depression, sleep hygiene is an important component of treatment, as
reduced sleep can sometime trigger a manic episode in a susceptible
individual.
Effects of Exercise on Depression
Recent
research has shown the effects of exercise on mood and anxiety. Although
the medical benefits of exercise are well known, the psychological
benefits are less understood. Adults who regularly exercise report lower
rates of depression and anxiety than the general population. Studies of
the effect of exercise on depression have demonstrated positive results.
There are many theories as to how exercise improves mental health.
Exercise causes changes in levels of serotonin, norepinephrine, and
dopamine and causes the release of endorphins (which masks pain). It may
reduce muscle tension, and adrenaline is released, counteracting the
effects of stress. Psychologically too, exercise improves self-esteem,
provides structure and routine, increases social contacts, and distracts
from daily stress. Although the degree of impact that exercise has on
depression needs more research, many good reasons exist for including
regular exercise as part of a treatment plan for depression.
