Greater Manchester, England, 8th October 2012: As the clocks go back, many of us look forward to toasty evenings filled with hot drinks, cosy slippers and great TV. But for others, the darker nights and mornings can really bring down their mood. While a lack of energy during the winter months is normal, Seasonal Affective Disorder is a genuine problem for many people. In fact, the Seasonal Affective Disorder Association claims that at least 7% of the population suffers from S.A.D between September and April. Symptoms can include depression, sleep problems, lethargy, over eating, loss of concentration, social problems, anxiety, loss of libido and mood changes.
