Medical Center of Aurora - November 05, 2018

While the cooler temperatures and shorter days of fall and winter mean relief from summer heat and sun, they can, for some people, bring changes in mood. These changes may take the form of seasonal affective disorder (SAD), a type of depression that occurs during particular seasons, then improves as the next season begins.

Do you think you may be effected by seasonal changes? The Medical Center of Aurora's Behavioral Health & Wellness Center is a great resource. Click here to learn more about services they offer.

In most cases, SAD is more pronounced during these colder months, says Christina Leal-McKinley, MD, of in Covington, Louisiana. Nearly half a million Americans experience symptoms of winter-related SAD each year and 10 to 20 percent of Americans have less severe symptoms, known as the winter blues.

While the exact cause of SAD is unknown, some people – including those who live in northern latitudes, those with a family history of SAD and those with depression or bipolar disorder – are at greater risk for SAD than others. Women are also more likely to have SAD than men.

Researchers have found that light has a lot to do with this disorder: a lack of sunlight may interrupt the body’s biological clock that usually controls mood, sleep and hormone levels. No matter what the cause, if left untreated, SAD can interfere with your everyday life and increase your risk of more serious health issues.

SAD signs to watch out for

A diagnosis of SAD is made if you have depression symptoms each season for two consecutive seasons. Symptoms of depression include:

  • Feelings of depression all day, on more days than not
  • Feelings of hopelessness
  • Decreased energy levels
  • Lack of interest in activities you once enjoyed
  • Sleep problems

 

There are also some signs that describe SAD specifically. In the winter months, those with SAD can expect to have:

  • Little energy
  • Exhaustion
  • A tendency to overeat and experience weight gain
  • Cravings for carbohydrates
  • Social withdrawal

 

Those with summertime SAD may notice:

  • Weight loss or decreased appetite
  • Sleeping problems
  • Anxiety
  • Irritability
  • Restlessness
  • Periods of violent behavior

 

How to ease symptoms of SAD

Symptoms usually improve as a new season begins, whether winter giving way to spring, or summer giving way to fall. But when you are at risk for SAD or have experienced symptoms in the past, it’s important to learn to identify and manage them so you can prepare for the changing seasons.

“Being cognizant of your seasonal shifts might help you become more aware of your mood fluctuations,” says Dr. McKinley. “We want to try to capture those changes when the season hits, so patients don’t suffer with the increased sleep issues, irritability and fatigue, which are all some of the downers that come with depression.”

She suggests getting regular exercise and sticking with the same wakeup and bed time every day (even on the weekends). She also suggests fueling your body with whole, nutritious foods that will help keep your energy levels up throughout the day. And be sure to get plenty of natural light: eat lunch at a park instead of your desk, open your blinds and sit closer to bright windows.

Beyond building a healthy lifestyle and sleep routine, here are some of the most common SAD treatment options:

Medication

This is usually prescribed as the first line of treatment for SAD. Medications are very effective on their own, or may work in conjunction with other treatment methods.

Certain antidepressants known as selective serotonin reuptake inhibitors (SSRIs) are typically used as the first drug of choice for SAD. It’s believed that they may help improve your brain’s serotonin levels, which can boost your mood.

“We will prescribe these medications to try and augment the neurochemicals that manage our behaviors and our mood,” says McKinley.

Your doctor may suggest that you take medication before the season begins and even after your symptoms have subsided to ensure they don’t return. It’s also possible that your doctor may try different medications to learn what works best for you and your symptoms.

Light therapy

This form of treatment has been around since the 1980s, and the main premise behind it is that increasing your exposure to bright, artificial light during the fall and winter months can ease the symptoms of winter-related SAD.

The treatment typically involves sitting in front of a light box that emits 10,000 lux of cool-white fluorescent light for 20 to 60 minutes each morning through the fall and winter months. Thankfully, there’s no need to worry about skin-damaging ultraviolet rays as long as you get a light box that filters out UV rays.

Psychotherapy

Known as talk therapy, psychotherapy can help with a wide assortment of mental and emotional health conditions like SAD, depression, anxiety, trauma or loss of a loved one.

There are many different kinds of talk therapy. Cognitive behavioral therapy (CBT) involves working to change behavior and thought patterns so that you can learn to focus on and solve problems. It also helps you recognize negative thoughts and learn to replace them with positive ones and can help you cope with the symptoms of SAD, as well.

Whether you’ve experienced SAD in the past, you’re currently dealing with symptoms of SAD or you’re looking to manage certain lifestyle factors to lower your risk of SAD, McKinley says regular appointments with your primary care provider are extremely beneficial.

You can discuss any mood fluctuations with her, and she can recommend therapies you should try or lifestyle changes you might need to make. And always, if you notice symptoms, don’t be ashamed to talk about them.

“See your doctor sooner rather than later,” says McKinley. “It’s important to know that you’re not alone and help is always available.”
