SAD: 10 Facts You Should Know

Fact #1: SAD is not a stand-alone disorder

Perhaps the biggest misconception about SAD is that it is a stand-alone disorder. In fact, SAD is considered to be a specifier within the larger workplace surveysspectrum of major depressive disorder (recurrent) that has seasonal attributes.

Translation – in plain-speak, you need to first receive a diagnosis of depression with a seasonal component in order to truly have SAD. It used to be that SAD was diagnosed as its own disorder however; changes in the new version of the DSM now place SAD as a kind depression offshoot. This is important because a specifier of SAD under the depression umbrella helps to further bolster the seriousness of this disorder and its impact on mood.

Fact #2: Cold weather does not cause SAD

While cold weather may cause many people to experience a case of the blues because they are forced to remain in doors, SAD really is not connected to outside, surface temperatures. Instead, the science tells depression winterus that SAD tells us that the onset of SAD is caused by a lack of natural sunlight. This lack of light somehow impacts brain chemicals, such as serotonin and melatonin, which influence mood.

It is important to note the correlation between weather changes and lack of sunlight. When days are shorter and sunlight is less available, people tend to head outside less. Isolating, lack of physical activity and lack of vitamin D can exacerbate symptoms of SAD.

Fact #3: You may crave carbs and chocolates

One of the symptoms of SAD relates to craving carbohydrates and chocolates. The reason is that carbs are sources of energy for the power of nobody. When we have a case of SAD, we typically feel less energy and less of desire to “move”. The urge to take in carbs may be your body’s way of trying to create more energy.

Chocolates are sometimes craved by people with SAD because they contain the amino acid, tryptophan, which is a precursor of the brain chemical, serotonin. Serotonin acts as a mood stabilizer and lifter within the brain. Lack of this chemical substance is thought to have a depressive impact on mood.

SAD Bonus Tip: The mood lifting benefits of chocolate should not be considered a permission slip to load up on lots of candy bars. While these little treats may taste good, they are often loaded with sugars and unhealthy fats. You may experience a temporary mood increase after gobbling down a bunch of chocolate but remember, what goes up, must come down – meaning your mood. It’s called a sugar crash.

Fact #4: Anxiety is a normal part of SAD

It is often said that depression’s best friend is anxiety. This is very much the case when working through a case of Seasonal Affective career counseling chicagoDisorder. While it is common to think that SAD makes us feel “down”, it is just as common to feel a bit anxious.

Anxiety in the context of Seasonal Affective Disorder often manifests in feeling restless, with pent up energy that can feel like it has nowhere to go. Some people experience the anxiety in the form of frustration.

SAD Bonus Tip: Cabin fever is not the same as SAD. While the cold weather outside may cause you to be sick and tired of sitting your home, it’s not the same as having SAD. They can feel the same but you have to look at the cluster of symptoms in their totality. Also, in order to be diagnosed with a SAD specifier for depression, you need to have at least a 2-year history of symptoms. Finally, the symptoms must remit when the seasons change.

Fact #5: SAD is not confined to winter

Fact #6: Higher latitudes more prone to SAD

While anyone can develop a case of seasonal affective disorder, it most commonly occurs in higher latitudes. For winter-type SAD, this means people living in Chicago, winter depressionNew York and Minneapolis are more prone to developing a case of “the winter blues” than folks living in Houston, Los Angeles or Miami.

This fact makes sense when you think about shortened days during the autumnal and winter solstice. Daylight savings time also impacts the number of hours we measure “daytime” and by extension, available sunlight.

Fact #7: Northern European decent SAD factor

Scientific research studies suggest that people of northern European 3d-abstract_widewallpaper_winter-sunrise_48384decent may be more prone to developing a case of seasonal affective disorder.

This fact is in line with fact #6, which relates to people in higher latitudes being more prone to coming down with a case of SAD.

Fact #8: Heredity may be a factor in SAD

Some lines of research studies suggest that heredity may be a factor for some people in the development of seasonal affective disorder. It iswinter-love-620x348 believed there is a genetic connection between serotonin secretions and a person’s ethnic background.

Levels of melatonin secretion and a person’s genetics and skin complexion (i.e. fair skin) seem to be related, according to these same lines of research. A lack of melatonin is thought to contribute to the onset of depression in SAD.

Fact #9: Women are more likely to develop SAD

Treatment of SAD

There are a number of effective treatments available for seasonal affective disorder, including several natural ones. Before continuing however, it is important to get evaluated by your medical doctor to rule out any physiological causes for depression.

Let’s look at a few of the treatment options:

Light Therapy

One of the most effective ways to combat seasonal type depression is through the use of a specially made SAD light-box. The light from the Incredible Naturebox artificially mimics pre-dawn natural sunlight, which in turn stimulates and then elevates the production of depression fighting brain chemicals.

You will want to get a light-box that has at least “10,000” lux. The term lux is a 25 cent phrase for lumen, which represents a unit of light measurement.

Typically, a person will use the light-box in the morning for about 30-minutes. Some people place their SAD lamp about a foot or so away from them while they sit on a couch. Others place the light-box next to their bed and then set a timer. While you do not need to sit directly in front of the light-box in order to experience benefits, it is important that you somehow face the light. For example, placing the SAD lamp on an angle so that it is in your peripheral vision is fine.

Potential side effects of SAD lamps, which are usually rare, can include increased irritability, eye strain, headaches and fatigue. These symptoms usually abate upon discontinuing usage of the light-box. You will want to talk to your medical doctor if these symptoms persist.

Finally on this point, it is important to note that SAD lamps emit all of the different colors of the light spectrum, which is required for effective light therapy. Tanning beds do not give off the same type of light. An easy way to remember this is that SAD LAMPS are created to mimic pre-dawn sunlight. Other artificial sources, like tanning beds, do not.

Although relief from SAD symptoms using a light-box can happen quickly for some, it may take several weeks for you to feel better. This is because it takes time for the brain to secrete the necessary chemicals to “push-back” against SAD related depression.


Physical Activity

There are a number of research studies that suggest physical activity and exercise are powerful combatants against depression. Strength training in particular may be a helpful natural remedy to consider in your struggle against SAD.

There exist a number of medications that are used for the treatment of depression, including SAD related depression. Currently, antidepressants, fluoxetine (Prozac) and bupropion (Wellbutrin) have been approved by the FDA for the treatment of SAD because the research indicates they are effective.

You will want to speak with your medical doctor or psychiatrist about the use of medications during a consultation to discover if medications are an option for your situation.


If you suspect you have seasonal affective disorder, you should make an appointment with your doctor. If your physician does not have experience with treating SAD, you may be offered a referral to another provider or to a psychiatrist. Your doctor will likely go over the potential risks and benefits of the various treatment options described here.
