Seasonal Affective Disorder 101

By Posted in - CPR Office on October 21st, 2015 0 Comments

Seasonal Affective Disorder (SAD) is on the rise as the sun finds itself setting earlier and earlier. This form of depression gradually appears in the fall and winter, the two seasons in which people tend to receive the least amount of exposure from the sun. SAD differs from Major Depressive Disorder (MDD) in that the symptoms typically go dormant in the spring and summer – but that doesn’t lessen its severity. For those who suffer from SAD, the fall and winter can seemingly go on forever, and it can be difficult to function during everyday life.

Typical symptoms of SAD include:

• Fatigueseasonal affective disorder 2_v_Variation_2
• Lack of interest in normal activities
• Social withdrawal
• Changes in appetite, such as craving foods high in carbohydrates
• Weight gain
• Irritability
• Low energy
• Hypersensitivity to rejection
• Oversleeping
• Feelings of depression, hopelessness, or worthlessness

Unsurprisingly, these are also common symptoms of MDD. About half a million Americans are negatively affected by the changing seasons and darkening of the summer light, so it’s important for sufferers to know they’re not alone and can receive assistance that can help push them through the darker days.

Here are some more facts about SAD:

1. SAD more commonly affects women
Women between ages 15 and 55 are at the highest risk of developing SAD, and SAD is about three times more common in women than it is in men.

2. It’s about sunlight – not the temperature
Some experts believe that reduced sunlight increases the body’s production of a body chemical called melatonin, which is what helps regulate sleep, and it can also cause symptoms of depression. An excess of melatonin can cause one to oversleep and to have low energy. In fact, melatonin is often recommended to MDD sufferers who have trouble sleeping.

While light therapy may not have long-term effects, it can be a great resource to help those affected with SAD to be exposed to more light. This kind of therapy involves exposure to a specialized light box for a prescribed period of time, and is more effective when used in the morning.

4. SAD can run in the family
Just like MDD and other mental illnesses, SAD can be hereditary. Studies suggest this because there is a genetic connection between serotonin secretions and a person’s ethnic background. Those of Northern European decent are at a high risk.

5. SAD can occur in the summer, too
It’s not as common, but summer depression is another form of SAD. Those affected usually start to experience symptoms like poor appetite, weight loss, and sleep disturbances stemming from things like the heat and humidity.
