What Is Seasonal Depression?
Seasonal depression is also known as Seasonal Affective Disorder (SAD). This is when you experience a change in your mood that is impacted by the seasons changing. Most people refer to this as the "winter blues" or “winter depression” because they experience it towards the end of fall and throughout winter. However, there are also people that experience seasonal depression in the spring and summer instead of the winter.
Who Is Likely to Experience SAD?
While it can impact anyone, some people are more likely to be diagnosed with seasonal depression than others. This includes people that are older than 20 years old. However, as you continue to age your chance of experiencing SAD continues to decrease. Another risk factor of SAD is the location where you live. According to American Family Physician, you are seven times more likely to be diagnosed with seasonal depression living in the state of Washington compared to living in Florida.
What Causes Seasonal Depression?
There are a few factors that are believed to contribute to someone experiencing the symptoms of seasonal depression. Since the majority of people experience the symptoms in the fall and winter, it's believed that the shorter days make the impact. People are getting less sunlight due to shorter days. Many areas get more cloudy days in the fall and winter months. During the winter, many people that work full-time arrive at work when it's dark and doesn't get to leave until it's dark again for the night. That means they are missing out on the beneficial vitamins that they can get from natural sunlight.
Time spent outdoors, and natural sunlight are natural mood boosters. When you stop getting the same amount that you are used to it can hurt the chemicals in your brain thus leading to a higher chance of depression.

SAD Light Therapy Box
One of the most popular forms of treatment for seasonal affective disorder is light therapy. These boxes go by several different names including bright light therapy boxes, phototherapy boxes, and simply light boxes. Even though they are called different names, they all do the same thing.
The purpose of light therapy boxes is to mimic the natural sunlight that you get outdoors. Since it's believed that natural light has an impact on your brain chemicals and mood, it's also believed that these light therapy boxes can do the same thing.

Many people use the light first thing in the morning within an hour of waking up for about 20 to 30 minutes. When you are using the light, you should stand with your face between 16 inches and 24 inches away. You will keep your eyes open, but you will not stare directly at the light.

The first considerations that you should make when considering light therapy boxes are the recommendations that came from your therapist or doctor. After that additional considerations could include:

- Eye damage - Some lights come with special features that will help protect you from eye damage
- Design - There are many different types of styles and designs that you can choose from. This is strictly a personal preference, but something you'll want to consider as you select your therapy light.
- How bright the light box is - If you are choosing a brighter light it will generally need to be used for a shorter period.
- UV light - You want to find a box that filters out the most amount of UV light possible to protect your skin while you expose yourself to the light.
The side effects of using light boxes are generally mild but could include eyestrain, headache, nausea, irritability or agitation, and mania, euphoria, hyperactivity or agitation associated with bipolar disorder. If you live with bipolar disorder, your doctor may recommend light therapy as a way to manipulate your circadian rhythm.

Instead, it's important that you take care of yourself. Open up your blinds and get whatever natural light you can even while you're inside. Make good choices with your eating, get in some exercise, and try to get the right amount of sleep.
