Now daylight saving time has ended, the days will start to get shorter and some individuals may experience Seasonal Affective Disorder (SAD).
What is Seasonal Affective Disorder?
SAD is a type of depression that comes and goes in a seasonal pattern.
SAD is sometimes known as “winter depression” because the symptoms are usually more apparent and more severe during the winter.
What causes it?
The exact cause of SAD is not fully understood, but it’s often linked to reduced exposure to sunlight during the shorter autumn and winter days.
The main theory is that a lack of sunlight might stop a part of the brain called the hypothalamus working properly, which may affect the:
- production of melatonin
- production of serotonin
- the body’s internal clock (circadian rhythm)
What are the symptoms?
Symptoms of SAD can include:
- a persistent low mood
- a loss of pleasure or interest in normal everyday activities
- irritability
- feelings of despair, guilt and worthlessness
- feeling lethargic (lacking in energy) and sleepy during the day
- sleeping for longer than normal and finding it hard to get up in the morning
- craving carbohydrates and gaining weight
- difficulty concentrating
- decreased sex drive
For some people, these symptoms can be severe and have a significant impact on their day-to-day activities.
Should I see a GP?
You should consider seeing your GP if you think you might have SAD and you’re struggling to cope.
Your GP can carry out an assessment to check your mental health. They may ask you about your mood, lifestyle, eating habits and sleeping patterns, plus any seasonal changes in your thoughts and behaviour.
Can it be treated?
A range of treatments are available for SAD. Your GP will recommend the most suitable treatment programme which could be:
- lifestyle measures
- talking therapies
- light therapy
- antidepressant medicine
