What Are The Signs Of Seasonal Affective Disorder?

Low Energy

One of the first symptoms of this condition seems to be low energy. It may be the only sign for some patients. Low energy may start in the fall. The lack of energy and fatigue may worsen as the days get shorter. It appears that this symptom occurs due to the lack of direct sunlight in the winter. The patient's brain may find it harder to stay awake. However, this symptom should disappear once winter has ended.

Patients may try light therapy for this symptom. Special lamps should mimic the effects of direct sunlight. However, these lamps do not seem to treat vitamin D deficiencies. Unfortunately, a lack of vitamin D can be a trigger for seasonal affective disorder. This may be because a strong source of vitamin D is the sun.
