The Relationship Between Seasonal Affective Disorder & Addiction

Seasonal affective disorder, also known as SADs, is a type of depression that occurs during certain seasons, typically in the autumn and winter months. It is believed to be caused by a lack of sunlight, which can disrupt the body's natural sleep-wake cycle and lead to feelings of sadness, fatigue, and decreased energy.

SAD is a common condition that affects millions of people around the world, and it can have a significant impact on an individual's overall well-being. Due to the lack of sunlight in the UK, everyone should be taking Vitamin D between October and early March, this is especially important as a lack of Vitamin D may make SAD even worse for many.

The Link Between SAD and Addiction

There is a strong connection between SAD and addiction, and individuals with SAD may be at an increased risk of developing an addiction to drugs or alcohol. This is because substance use can provide temporary relief from the negative symptoms of SAD and can also help to improve mood. However, the use of these substances can also lead to a cycle of dependence and further worsening of SAD symptoms in the long term.

Risky Behaviours and SAD

In addition to the link between SAD and addiction, individuals with SAD may be more likely to engage in risky behaviours, such as binge drinking or drug use, as a way to cope with their negative emotions. This can further increase the risk of developing an addiction.

It is important for individuals with Seasonal Affective Disorder to seek out healthy coping mechanisms, such as exercise, therapy, and spending time with loved ones, rather than turning to substances as a way to cope with their symptoms. Treatment for SADs may include light therapy, medications, and talk therapy, which can help to improve mood and reduce the risk of developing an addiction.

If you or a loved one is struggling with SAD and addiction, it is important to seek professional help.
