Understanding Seasonal Affective Disorder (SAD)

Seasonal Affective Disorder (SAD) is a type of depression that follows a seasonal pattern, typically worsening during the winter months when daylight hours are shorter. However, some people may experience SAD during the summer.

Symptoms

Common symptoms of SAD include:

• Persistent low mood
• Loss of interest in everyday activities
• Irritability
• Feelings of despair, guilt and worthlessness
• Lethargy and daytime sleepiness
• Changes in appetite
• Difficulty concentrating
• Decreased sex drive

These symptoms can significantly impact daily life and may vary in severity from person to person.

Causes

The exact cause of SAD is not fully understood, but it is often linked to reduced exposure to sunlight. This lack of sunlight can affect the production of hormones such as melatonin and serotonin, which regulate sleep and mood, respectively. It can also disrupt the body’s internal clock (circadian rhythm), leading to symptoms of depression.

Treatment

Several treatments are available for managing SAD:

Lifestyle Changes: Increasing exposure to natural sunlight, regular exercise and stress management.

Light Therapy: Using a light box to simulate sunlight exposure.

Talking Therapies: Cognitive Behavioral Therapy (CBT), Psychotherapy, counselling or psychological counseling provided by a psychologist or counsellor.

Medication: Antidepressants, particularly selective serotonin reuptake inhibitors (SSRIs).
