Seasonal Affective Disorder

Symptoms, Causes and Prevention


Seasonal affective disorder (SAD) is a form of depression that typically occurs in the winter months, and the “winter blues” are a milder form of SAD. Additionally, SAD is a recognised mental health disorder that affects 8% of the UK every year. Also, the “winter blues affects 21% of the UK’s population.

Seasonal affective disorder affects us both physically and mentally, and symptoms can be mild to severe. Depending on the weather, symptoms can start as early as August. But, usually, symptoms are worse from November to February and dissipate around April. Symptoms may include fatigue, irritability, and notable lack of concentration, depression and anxiety. As a result, for some people, SAD can have a significant detrimental impact on their lives.

Furthermore, we spend 90% of our time indoors unexposed to natural light and subjected to artificial light. Also, when we do go outside, we spend a considerable amount of time wearing sunglasses which blocks our exposure to sunlight. So, to reduce the effects of SAD, we need at least thirty minutes per-day outdoor exposure to natural light without sunglasses.
