Some 500,000 people are affected by Season Affective Disorder (Sad) between September and April, according to a support organisation.

The condition is most likely to first affect people during their thirties and around twice as many women are impacted upon by the disorder than their male counterparts, the Scotsman reports.

Warning indicators of the condition that may occur during the colder months of the year may include depression, lethargy, problems interacting socially and anxiety, reports the association, which also states that a diagnosis can be made after three consecutive winters of the symptoms.

Techniques to help with the condition may be particularly useful to elderly people as they may already find it difficult to get out and about during the winter months.

Methods to remain upbeat throughout the winter months recommended by the Scotsman and Sad Association include exercise, illumination therapy with a light box, counselling to help with relaxation and eating a balanced diet.

In news that may also be of relevance to older people, Help the Aged recently stated that applications for winter fuel allowances must be made before September 21st to ensure that the financial help is received by Christmas.
