Seasonal Affective Disorder (SAD) and winter blues
Animals react to the changing seasons with changes in mood, metabolism and behaviour and human beings are just the same. Many people find they eat and sleep slightly more in winter and dislike the dark mornings and short days and this is commonly referred to as 'winter blues'. For some, however, symptoms are severe enough to disrupt their lives and to cause considerable distress. These people are suffering from SAD.
How does SAD affect people?
Symptoms tend to start from around September each year lasting until April, but are at their worst in the darkest months. Symptoms include:
Sleep problems - oversleeping but not refreshed, cannot get out of bed, needing a nap in the afternoon
Overeating - carbohydrate craving leading to weight gain
Depression, despair, misery, guilt, anxiety - normal tasks become frustratingly difficult
Family / social problems - avoiding company, irritability, loss of feeling
Lethargy - too tired to cope, everything an effort
Physical symptoms - often joint pain or stomach problems, lowered resistance to infection
I have it. Bad. Hey-I have SAD, bad.
Lights aren't working.
Would someone please tell me a joke or a riddle. Something. Anything.
My brain needs to go on life-support. I can't take the gray much longer.
Yes, I am using my very own, personal blog to vent. Vent, vent, vent.
There. Now I feel better.
