February is the shortest month on our calendars. Psychologically, however, it is also the longest month. Leafless trees, barren landscapes, minimal sunlight, and frigid temperatures can wear a person down. For some, these environmental factors may produce symptoms of mild depression.
Seasonal Affective Disorder, or SAD, is a form of depression that impacts a person during the same season each year. If you feel depressed in the winter, but your mood and affect improve during the spring and summer months, you may have SAD.
SAD is quite common and can affect anyone, but it is more prevalent in women between the ages of 15 and 60. Anyone who lives in a climate with extended winter months where daylight is at a premium is at risk to develop symptoms associated with SAD. However, first onset symptoms are less likely to occur as you age. In other words, If you don’t experience SAD symptoms before the age of 40 you are unlikely to develop symptoms later in life. Keep in mind, SAD is a type of depression and should not be confused with mild or moderate depression.
There is no smoking gun to indicate a definitive root cause for SAD. The one apparent link that appears to be most prevalent is lack of sunlight. This may also disturb your sleep-wake cycle and circadian rhythms, and lack of sunlight may account for a drop in the brain chemical serotonin, which is linked to mood.
Some of the symptoms you may experience with SAD include a loss of interest in activities you normally find enjoyable, craving foods high in carbohydrates, such as pasta or bread, weight gain, feelings of sadness, irritability, constant worry, and drowsiness even after a full night’s sleep. Treatment may involve light therapy. Light therapy works very well for most people diagnosed with SAD, and it is easy to use. Typically, individuals report feeling improvements to mood within two weeks of starting light therapy. Like any other treatment, you must be consistent and use the therapy on a daily basis. Otherwise, results will not be as effective.
In Good Health,
