Is Seasonal Depression Common?
Seasonal depression, also known as
seasonal affective disorder, is a mood disorder and a set of annually recurring
symptoms that affects people who enjoy otherwise normal health during the rest
of the year. The symptoms come mostly during the winter and they are most
common in geographic regions that get long, cold winters.
The causes of seasonal depression
can be linked to the shortness of winter days and to the scarcity of natural
light during the cold months. Sunshine triggers the production of certain
mood-enhancing chemicals, especially serotonin and melatonin, in the human body
– when we see very little of the sun, our bodies cannot produce the hormones in
sufficient quantities. The shortage generates symptoms that range from sleeping
too much, fatigue, the lack of energy and motivation to do anything and, in
most severe cases, depression.
Some patients experience seasonal
depression in spring and in summer. While winter depression usually takes the
form of lost interest and feelings of sluggishness, spring and summer
depression usually takes the form of insomnia, agitation and anxiety, the exact
opposite of the symptoms associated with winter depression.
The Littleton counseling treatment for seasonal depression usually includes psychotherapy and medication, in the case of winter
depression accompanied with phototherapy, that is, with the exposure to light
in order to induce the production of more melatonin and serotonin.
