SAD in the UK
- Seasonal affective disorder (SAD) affects approximately 2 million people in the UK
- It causes depression, fatigue, carbohydrate craving, and sleep changes during winter months
- Treatment includes light therapy, antidepressants, and psychotherapy
- Medical cannabis may offer complementary benefit particularly for sleep and mood
The UK’s northerly latitude and limited winter daylight makes SAD particularly common.
Relevant Mechanisms and Access
- CBD has demonstrated anxiolytic and antidepressant properties in clinical studies
- Sleep regularisation with cannabis may help with the circadian disruption underlying SAD
- Evening dosing with a CBD-dominant oil is typically the first approach for SAD patients
- Light therapy should continue alongside cannabis — they are complementary approaches
SAD patients may find cannabis addresses sleep and mood components simultaneously, potentially with less side effect burden than antidepressants.
