BEWARE! IT’S TIME FOR SAD (SEASONAL AFFECTIVE DISORDER)

Seasonal Affective Disorder (SAD) affects about 5% of us

severely and perhaps 25% of us more mildly. Women and

young adults are more likely to suffer from it.



It’s a form of depression that, according to the National Mental

Health Association (NMHA), is a real illness with sometimes

severe symptoms. It’s worse in January and February, though

starts as early as September.



SAD is believed to be caused by melatonin, a sleep-related

hormone secreted by the pineal gland in the brain. Melatonin

production increases in the dark, so in the winter, when the

days are shorter and darker, production increases, causing

symptoms of depression.



SAD is extremely rare for people living within 30 degrees of the

Equator, where daylight hours are long and extremely bright.



The Symptoms?

Sleep problems, lethargy, overeating, depression, social

problems, anxiety, loss of libido, mood changes, and a

weakened immune system. For complete description, go here: http://www.sada.org.uk/symptoms.htm.



The Cure?

Light suppresses the secretion of melatonin, so for lighter

cases, get outside more, exercise outside, and arrange for

more light at work and at home.



Phototherapy has been helpful in more severe cases. A light

box can be used that emits very bright light through a filter.



Please check with your personal physician if you think you

have SAD.
