Seasonal Affective Disorder

SAD stands for Seasonal Affective Disorder. Although most people feel a little down when winter hits, SAD sufferers have symptoms that are severe enough to disrupt their lives.

Is the weather affecting your mood more than usual?

What is Seasonal Affective Disorder?

It is common for dull weather and short daylight hours to dampen your mood. Seasonal Affective Disorder (or SAD) is when the winter weather affects your mood so much that you feel depressed.

Symptoms:

  • Sleep problems: oversleeping (but not feeling refreshed) and difficulty staying awake, or in some cases disturbed sleep and early morning wakening
  • Lethargy: too tired to cope, everything becomes an effort
  • Overeating: craving for carbohydrates and sweet foods leading to weight gain
  • Depression: feelings of despair, misery, guilt, anxiety, hopelessness, normal tasks become frustratingly difficult
  • Social problems: avoiding family and friends, irritability, inability to handle stress, feeling emotionally numb, loss of libido
  • Physical symptoms: often joint pain or stomach problems and a lowered resistance to infection
  • Behavioural problems: extemes of mood and short periods of overactivity in spring and autumn.

When does it start?

The symptoms tend to start around September and last until April. They are at their worst in the darkest months.

What causes it?

It is said to stem from the lack of bright light (daylight and sunlight) in winter, causing a biochemical imbalance in the brain.

Who does it affect?

Roughly 2% of the population of Northern Europe suffer badly, with many more (10%) suffering milder cases. Across the world the incidence increases with distance from the equator, except where there is snow on the ground when it becomes less common. More women than men are diagnosed as having SAD. Children and adolescents are also vulnerable.

What treatment is there for SAD?

A perfect cure is going to a brightly lit climate, whether skiing or somewhere hot (any excuse for a holiday!)

Otherwise, exposure to bright light every day by using a light box or a similar bright light therapy device may help. For most people, sitting in front of a light box for between 15 and 45 minutes a day (not staring at the light but allowing it to reach their eyes) will be sufficient to alleviate the symptoms. Some sufferers also need treatment with antidepressant medication.

Should I talk to my doctor?

Yes. They can tell you where the NHS specialist SAD clinics are in the UK, and help you seek treatment.
