Daylight Saving Time: Enjoy the Extra Hour, But Watch for Seasonal Affective Disorder (SAD)
Getting that extra hour of sleep this weekend sounds fantastic, but unfortunately, the shift in time can signal a difficult time for many. Daylight saving time ends Saturday, Nov. 4, which often coincides with the onset of Seasonal Affective Disorder (SAD).
SAD is a type of clinical depression that follows seasonal patterns. Symptoms typically manifest during fall and winter and lessen in spring and summer. Kelly Rohan, a psychology researcher at the University of Vermont, explains, “SAD, or seasonal affective disorder, is a form of clinical depression that follows a seasonal pattern where the depression symptoms are in effect during certain seasons of the year and they resolve in the opposite seasons of the year.”
Understanding SAD:
Scientists have discovered that specialized cells within our eyes convert blue light wavelengths into neural signals which impact mood and alertness.
Sunlight is brimming with blue light, naturally influencing our circadian rhythm, and reducing daylight hours affect our bodies’ production of serotonin, a mood-boosting neurotransmitter, leading to SAD symptoms for some.
Fortunately, scientists are constantly learning more.
“There are many helpful treatments for seasonal depression. These include antidepressant medications, bright light therapy, and cognitive behavioral talk therapy, “
Rohan
Treat SAD:
Bright Light Therapy:
Bright Light Therapy involves devices emitting about 20 times stronger light than regular indoor lamps. These devices are widely recommended for 30 minutes daily, ideally in the morning, to mimic natural daylight and regulate your circadian rhythm.
Embrace the Outdoors:
Even amidst the shorter days, venture outside whenever possible. Despite the lack of sunshine we often associate with winter months, there’s ample light to be found – just dress warmly!
Rohan advises, “Try to get outside as much as possible. There’s plenty of light to be had in the wintertime. You just have to dress appropriately.”
While a summer version of SAD exists, research remains limited on this form of the condition.
If you struggle with symptoms of depression throughout the year, consult your doctor or a mental health professional for personalized guidance.
