What is Seasonal Affective Disorder (SAD)?
SAD is a medically recognised form of depression which affects 8% of people
in the UK. A further 21% of people in the UK experience a milder form of SAD
often referred to as ‘Winter Blues’.
The ‘Winter Blues’ can lead to individuals feeling tired, lethargic and ‘fed-
up’. By contrast, SAD is a seriously debilitating condition, which can leave
sufferers medically depressed. SAD can lead to problems in relationships,
unemployment and even suicide.
Lack of light causes SAD. Symptoms are common during the darker months
from August through to April, but can equally be triggered during exceptionally
dull summers or dark home/work environments. SAD can occur anywhere, but
is more prevalent in those living further away from the equator.

often worsening as the days get darker. Initial symptoms can help the individual
