How to Combat Seasonal Affective Disorder

How to Combat Seasonal Affective Disorder


 
When the nights draw in and the weather becomes colder, it can be common for us to feel a little 'fed-up', especially with all the trauma and stress we have had to endure with the pandemic this year.
 
We are often stuck inside, there isn't a lot of daylight and the weather can be less than desirable, the winter months can easily affect our mood.
 
However, this seasonal change can cause more severe mental and emotional stress for some people and can have a negative impact on their everyday life.
 
Seasonal Affective Disorder is commonly associated with low mood occurring in winter, but what is it?
 
Is it a real disorder or just another name for the 'winter blues'?
 
In this guide, we're going to explore everything to do with Seasonal Affective Disorder and what you can do to cope with it this winter.
 
 

Is Seasonal Affective Disorder real?

 
Seasonal Affective Disorder (also known as SAD) was first described as a mental health condition by Dr Norman E Rosenthal in a journal article in 1984.
 
However, the Diagnostic Manual of Mental Disorders classed SAD as a type of depression rather than a unique mental illness.
 
SAD is a recurring, seasonal form of depression that people experience at the same time every year - most commonly in the winter months.
 
Unlike the 'winter blues', it is a lot more severe than just feeling a bit low.
 
SAD can be debilitating and cause a lack of energy, low mood and may prevent you from carrying our normal day-to-day activities.
 
If you notice that you feel depressed at a similar time every year and that it is periodical, with long periods without depression, you may have Seasonal Affective Disorder and you should seek advice from your GP.
 
 

How is Seasonal Affective Disorder diagnosed?

 
As SAD can be similar to other types of depression, it can be a little tricky to diagnose, so it may take some time to identify if you have the condition.
 
Your GP may ask you questions about:

  • Your mood
  • Your diet, sleep and lifestyle
  • How your thought and behaviour changes during the year
  • The severity of symptoms - how are they affecting your life?
  • Family history of depression

 
The diagnostic criteria for Seasonal Affective Disorder are symptoms of depression starting and ending within a specific season every year for at least two years and not experiencing depression during other seasons.
 
It may be useful to keep a diary to track your mood and identify when your symptoms occur.
 
 

What does Seasonal Affective Disorder feel like?


 
SAD has the same symptoms as depression, but rather than being present all of the time, you will experience them during a season.
 
Symptoms of SAD include:

  • Sleeping much more than usual
  • Eating more than you normally do
  • Frequently feeling 'low'
  • Lack of interest in activities and hobbies you normally enjoy
  • Low energy
  • Lack of motivation
  • Low energy
  • Feeling hopeless or worthless
  • Difficulty concentrating
  • Socially withdrawal
  • Thoughts of death, harming yourself or suicide
  • Reduced libido (sex drive)

 
SAD may affect your life by putting strains on your relationships due to isolating yourself, mood changes and lack of sex drive.
 
You may also find it difficult to work due to difficulty with concentration and lack of motivation.
 
Seasonal Affective Disorder is commonly associated with feeling down and sluggish, but it can also make you feel anxious, irritable and stressed.
 
If you are frequently feeling stressed and anxious when struggling with SAD, you also may be more susceptible to tension headaches, as you may find it difficult to relax.
 
 

Why does Seasonal Affective Disorder occur?

 
Since it was first formally described in the 1980s, there has been quite a lot of research into SAD and how the condition is triggered.
 
One theory that has been discussed is the lack of sunlight, commonly experienced in winter, can affect the body's hormones and chemicals in the brain.
 
It has been discussed that this change in hormones and chemicals could cause the hypothalamus working properly, which can disrupt your mood, sleep and appetite.
 
Another possible cause is the effect of a chemical called Melatonin.
 
Melatonin is a chemical that makes you feel sleepy and is produced in a small gland in the brain.
 
During the winter months some people create high levels of melatonin which can cause symptoms, such as sleepiness and low energy levels that are associated with SAD.
 
Serotonin is a hormone that is commonly associated with depression, as low serotonin levels cause people to experience depressive symptoms.
 
Fewer hours of sunlight can cause less serotonin to be produced and therefore can cause Seasonal Affective Disorder symptoms.
 
Other causes that could potentially trigger SAD symptoms include:

  • Circadian rhythm - our body uses light sources to time various bodily functions, so a lack of light in winter can disrupt this rhythm
  • Genetic factors - a history of depression within your family could mean you are more likely to experience depression
  • Childhood trauma
  • Social factors, such as your relationships with your friends and family

 
Although SAD is commonly associated with winter it can, rarely, happen during other seasons, including summer.
 
No matter when you experience these symptoms or whether you have noticed a pattern in your symptoms, you can seek help and advice from your GP to identify why you are experiencing depression symptoms and what treatments are available to you.
 
 

How to treat symptoms of Seasonal Affective Disorder


 
There is no cure for SAD, but there are steps you can take to help manage your symptoms.
 
The first step you can take is visiting your GP to discuss your symptoms and what is the best treatment for you.
 
It has been recommended by the National Institute for Clinical Excellence (NICE) to treat SAD in the same way as other types of depression.
 
This means that treatments, such as antidepressants and talking therapies, like Cognitive Behavioural Therapy can be used to help manage symptoms.
 
Common treatments for Seasonal Affective Disorder include:

  • Cognitive Behavioural Therapy (CBT)
  • Counselling
  • Antidepressants
  • Light therapy

 
 

What is the difference between Cognitive Behavioural Therapy and Counselling?

Cognitive Behavioural Therapy is a talking therapy that aims to change your thought processes and behaviour when faced with certain situations.
 
It involves a number of sessions with a trained therapist who will talk through your symptoms and behaviour and create a programme to help you change your behaviour to manage your symptoms.
 
Counselling is another type of therapy that involves speaking to a trained counsellor about your problems and worries.
 
It encourages you to open about your feelings and emotions with the therapist who is there to listen and support your thoughts and concerns without judgement.
 
Unlike Cognitive Behavioural Therapy, the aim is for you to gain a better understanding of your feelings and thought processes rather than a therapist telling you what to do.
 
The words 'therapy' and 'therapist' tend to conjure up mental images of lying on a couch talking about your feelings and your childhood whilst a person sitting in a chair takes notes.
 
This can be the case in some circumstances, but technology and approaches to talking therapies have moved on and now therapy can take place in a variety of settings such as:

  • 1 - 1 meetings face-face with a therapist
  • Group meetings with other people who feel similarly to you
  • Over the phone
  • Online through live chats and websites
  • Couples sessions if your symptoms are affecting your relationship

 
 

How can antidepressants help to manage SAD

Antidepressants are a type of medication that are used to manage depression symptoms and are also sometimes prescribed to treat severe symptoms of SAD.
 
The type of antidepressants that are usually prescribed by doctors for SAD are called Selective Serotonin Reuptake Inhibitors (SSRIs).
 
They work by increasing levels of serotonin in your brain to lift your mood.
 
However, they are not a magic tablet that can instantly make you feel better, as they can take between 4 - 6 weeks to take full effect.
 
It may also be recommended by your doctor to use a talking therapy, such as CBT alongside using medication to manage SAD.
 
 

How does Light Therapy work?

 
Light Therapy is a form of treatment of SAD that has been used since the 1980s.
 
It involves using a bright lamp (also known as SAD Lamps, Light Boxes or Daylight Therapy Lamps) which works by bringing more light into your environment during the day.
 
They come in different sizes and styles including desk lamps and bedside lamps.
 
SAD lamps tend to be around 20 times brighter than normal indoor lights and filter out harmful UV rays, so are safe to use for most people.
 
It is thought that Light Therapy Works by simulating sunlight which encourages the brain to reduce the production of melatonin and increase the production of serotonin to prevent you from feeling sleepy and lift your mood.
 
 

Do SAD lamps work?

 
Although it is a treatment that is commonly associated with SAD, there is mixed evidence regarding the effectiveness of Light Therapy using SAD lamps.
 
The treatment is based on the theory that a lack of light can affect the hormones and chemicals released in your brain.
 
It is difficult to prove how effective SAD lamps are, as research has been carried out using different light sources and experiments to test the effectiveness of Light Therapy has been conducted over short periods of time.
 
However, there is some evidence to suggest that Light Therapy can be effective especially when used first thing in the morning.
