Understanding the Impact of Seasonal Affective Disorder (SAD)

As the seasons change, so can our moods. For some, shorter days and colder temperatures bring more than just a preference for cosy blankets—they can trigger Seasonal Affective Disorder (SAD), a type of depression linked to changes in daylight exposure. Below, we answer common questions about SAD and how to manage its effects.

What Is Seasonal Affective Disorder?

SAD is a form of depression that typically occurs during winter when daylight hours are shorter. Symptoms often include:

• Persistent low mood

• Fatigue and lack of motivation

• Difficulty concentrating

• Increased need for sleep

• Changes in appetite, often craving carbohydrates

Why Does It Happen?

• SAD is believed to be linked to:

  • Reduced sunlight exposure, which affects melatonin and serotonin levels.

  • Disruptions to the body’s internal clock, leading to changes in mood and energy levels.

  • Vitamin D deficiency, as sunlight is a primary source of vitamin D production.

How Can You Manage SAD?
Some ways to help mitigate the effects of SAD include:

• Maximising daylight exposure – Spending time outside during daylight hours can help regulate mood.

• Creating a bright environment – Using light therapy lamps or keeping curtains open can increase light exposure indoors.

• Maintaining a routine – Sticking to a regular schedule for sleep, meals, and exercise can help stabilise mood.
