You may have heard the tern "SAD",
which stands for Seasonal Affective Disorder. It's a kind
that the pineal gland, a small structure located near the
center of the brain,
plays a role in SAD. The pineal gland is activated by light. Many people who suffer from SAD
have been able to relieve their symptoms through exposure to a special artificial light for thirty
minutes or more each morning and evening.
|SAD is also
referred to as "winter blues". The lack of
sunlight in winter
causes a reaction and the person develops mild or major depression from late
fall until early spring. This condition is more commoj the further away from
the equator you go. For the Northeren hemisphere the worst minths are
December, January, and February.
