Do you dread the bleak winter months? If you find that your mood changes drastically during winter, you could be suffering from Seasonal Affective Disorder (SAD). Mental health issues such as low mood and depression can occur all year round, but new cases of low mood in winter could actually be due to SAD. Whatever the case, our kind and experienced private doctors are always happy to help.

What is Seasonal Affective Disorder?

This is a type of depression that is experienced by some people at the same time each year. If you have SAD, you may find that your symptoms start in the autumn and continue through the winter, improving markedly when the spring arrives. SAD is not the same as clinical depression, although the two are related.

SAD vs Depression: What's The Difference?

The difference between depression and SAD is that people who suffer from SAD often have normal mental health throughout the year, but notice that they suffer depressive symptoms at the same time each year, usually when the nights begin to get dark and the weather worsens. A smaller number of people are affected by SAD during the summer months.

What Causes SAD?

Seasonal Affective Disorder seems to develop as a result of inadequate exposure to bright light during the winter months.

Factors which may increase your risk of developing SAD include:

  • Female gender
  • Younger age
  • Having a relative who suffers from SAD or depression
  • Suffering from another mental health condition
    • such as bipolar disorder or depression
  • Your location
    • SAD appears to be more common amongst people who live far North or South of the equator, where there is less sunlight available during the winter


Symptoms of Seasonal Affective Disorder

As with depression and other mental health conditions, the symptoms of SAD should be taken seriously, as it is a real mental health condition which is very treatable.

Watch out for the following symptoms:

  • Feeling a persistent change in mood
  • Loss of energy
  • Loss of interest in hobbies that you used to enjoy
  • Wanting to sleep or eat more than usual
  • Feelings of pessimism or hopelessness
  • Wanting to be alone
  • Weight Gain
  • Difficulty concentrating, or inability to finish tasks
  • Decreased sex drive

Like any mental health or medical condition, SAD can get worse if it's not treated, and in some severe cases it can lead to problems at school and work, social withdrawal, or even suicidal thoughts or behaviour. Thankfully, with the help of a professional who understands your condition, there is a lot you can do to ensure this doesn’t happen to you.

I Think I Have SAD: What Should I Do?

The first step is to tell someone who can help you, and your doctor is a great place to start. Your GP may carry out a psychological assessment to check your mental health. You might be asked questions about your mood, eating and sleeping patterns, your lifestyle, and your personal and family history. Your GP will likely want to distinguish between your functioning in these areas during the winter months vs the rest of the year.

You may also undergo a brief physical examination, or maybe even some blood tests to rule out possible physical causes of your symptoms. For example, anaemia is a common cause of tiredness, which can in turn lead to low mood.

SAD can be a tricky condition to diagnose because there are other types of depression that have similar symptoms. It may take a while before you and your GP realise that your symptoms are forming a regular pattern.

A diagnosis of SAD may be considered if:

  • you have suffered similar symptoms during the same season for at least two years in a row
  • the periods of low mood are followed by periods when you feel much better
  • there are no other obvious explanations for your seasonal mood changes


How To Improve Your Mood

There are a number of simple lifestyle changes you can make to improve your symptoms:

  • Maximise your exposure to natural, bright light - get outside during the daylight hours, make your home and work environments as bright as possible, and sit near windows when indoors
  • Exercise - especially outside! Physical activity is a well-known mood booster
  • Eat a healthy, well balanced diet
  • Get support - talk to your family and friends about your condition, and help them to understand why your behaviour changes in the winter months. Understanding this can help them to support you more effectively

Outdoor exercise, to treat SAD, depression

Outdoor activities, such as running or hiking, are a great way to combat SAD - by getting both exercise and essential sunlight at the same time
