SAD (Seasonal Affective Disorder) – what really is the ‘winter blues’?

It is a known fact that the winter months can affect our mood, for better or worse. But are we experiencing Seasonal Affective Disorder, or have we just got a case of the ‘winter blues’? 

Seasonal Affective Disorder (SAD) is a type of depression which is affected by the change in seasons; it is more commonly known as ‘Winter Depression’ because the majority of those diagnosed with SAD experience their symptoms during the winter season (from September to as late as April). 

SAD is a medically recognised disorder and can vary in seriousness from person to person. It is estimated that around 6% of people diagnosed with this disorder experience symptoms so severe that they could not continue with their day-to-day life. However, the majority of people across the globe experience some form of SAD in the winter months. It is scientifically proven that a lack of sunlight, dull weather and shorter hours (daylight savings) causes a chemical imbalance in the brain that causes symptoms of SAD. 

Before continuing, it is important to note that it is common for the dull weather and lack of sunlight to dampen your mood, and many people may suffer from a mild version of SAD. However, diagnosed Seasonal Affective Disorder is when your mood is so low that you are unable to continue with aspects of your daily life due to the symptoms listed below.  

What are the symptoms of Seasonal Affective Disorder?

According to the NHS, the symptoms of SAD are as follows:

  1. A persistent low mood
  2. A loss of motivation or interest in everyday activities
  3. Low self-esteem
  4. Feeling irritable, stressed or anxious
  5. A reduced sex drive
  6. Becoming less sociable
  7. Feeling lethargic 
  8. Sleeping for longer than normal, or finding it harder to wake up in the mornings

If you experience these symptoms and notice a persistent change in mood during the winter months, you could be experiencing SAD and you should contact your GP for further advice. 

It is important to note that it is very difficult to diagnose this disorder as it can take a long time to examine and there are many other forms of depression with the same, or similar, symptoms. 

How can it be treated?

For diagnosed SAD, you may be prescribed certain medication to alleviate your symptoms (such as antidepressants or CBT). Some scientists also suggest therapy or, more specifically, Light Therapy (where you sit under an artificial light source for 30 minutes to an hour each day).

At-home treatments of SAD (not medically prescribed by a doctor) can be:

  • Regular exercise – fresh air is super important!
  • Especially since most people are working-from-home, try and make your bedroom and workspaces as light and airy as possible: sit next to an open window, decorate your room with lights and make sure it’s nice and clean!
  • Some people find sun light alarm clocks really useful!
  • You’ve heard it too many times before but, eat a balanced and healthy diet! I promise it will be worth it.
