As the days grow shorter and the world outside becomes a sea of grey, many people find themselves struggling to muster the energy and enthusiasm that the warmer months effortlessly provide.


This annual phenomenon is known as Seasonal Affective Disorder, or SAD, a condition that affects millions of people worldwide. In this feature, we’ll explore the causes, symptoms, and treatment options for SAD, shedding light on this often-misunderstood disorder.

Understanding the Cause

SAD is a type of depression that typically occurs during the autumn and winter months when daylight hours are limited. Researchers believe that a combination of biological, psychological, and environmental factors contribute to its development. The primary cause is thought to be a disruption in the body’s internal biological clock, or circadian rhythm, due to reduced exposure to natural light. This disruption can lead to an imbalance in neurotransmitters like serotonin and melatonin, which regulate mood and sleep.

Symptoms of SAD

SAD can manifest in a variety of ways and may differ in intensity from person to person. Common symptoms include:

  • Mood Changes: People with SAD often experience persistent feelings of sadness, hopelessness, and irritability.
  • Sleep Disturbances: Oversleeping and difficulty waking up in the morning are typical symptoms of winter SAD. This is often accompanied by daytime fatigue.
  • Changes in Appetite: An increased craving for carbohydrates and a resulting weight gain are common. These cravings are believed to be linked to serotonin levels.
  • Social Withdrawal: Many individuals with SAD tend to withdraw from social activities and isolate themselves from loved ones.
  • Difficulty Concentrating: People with SAD may have trouble focusing on tasks and making decisions.

Treatment Options

The good news is that SAD is a highly treatable condition, and a variety of therapeutic approaches are available to help individuals manage their symptoms. Here are some effective treatment options:

  • Light Therapy: Light therapy, also known as phototherapy, is a widely used treatment for SAD. Patients sit in front of a specialised lightbox for a designated period each day, which mimics natural sunlight and helps regulate their circadian rhythms.
  • Cognitive-Behavioural Therapy (CBT): CBT is a talk therapy that helps individuals identify and change negative thought patterns and behaviours. It can be highly effective in managing SAD symptoms.
  • Medications: In some cases, doctors may prescribe antidepressant medications, such as selective serotonin reuptake inhibitors (SSRIs), to help manage the symptoms of SAD.
  • Lifestyle Changes: Simple lifestyle adjustments, such as getting regular exercise, maintaining a healthy diet, and managing stress, can also help alleviate SAD symptoms.
  • Vitamin D: Some individuals with SAD may benefit from vitamin D supplements, as a deficiency has been associated with the condition. However, it’s important to consult a healthcare provider before taking any supplements.

Seasonal Affective Disorder is a genuine and challenging condition that affects a significant portion of the population during the darker months of the year. Understanding its causes, recognising its symptoms, and exploring the available treatment options can make a significant difference in the lives of those affected by SAD.
