To get you through the dark days until spring, psychiatrist
Edwin Tam at Columbia University\'s Center for mood disorders in the UK explains how seasonal mood disorders work. 1. What is it?
Seasonal Affective Disorder is a type of severe depressive disorder or bipedal disorder in which symptoms occur only during the fall/winter season.
These include excessive sleep, extreme fatigue, difficulty in concentration, a desire for carbohydrates, and increased weight resulting in changes in appetite.
With more serious events, people will have a feeling of no value or guilt, and people may have the idea of suicide.
\"We will diagnose it in the way we diagnose depression, that is, basically you have been frustrated for two weeks in a row, or just lost interest and lack of happiness, Tan said.
\"Did you slow down a little bit?
It\'s hard to find a job and you don\'t have so many social activities.
\"It can be sad if these five symptoms persist. 2. What causes it?
Studies have shown that light has an effect on the chemistry and function of the brain.
\"Dormant animals will actually be told how long it will take for a few days,\" Tam said . \".
\"You can fool the animals in the lab by artificially shortening the time and make them think it\'s winter --
Before turning off the lights (in the evening)
, Open them later in the day.
Tam said they believe some people have a similar reaction to the length of the day.
\"Other people, maybe jet planes. lag hypothesis;
You get up in the morning and it\'s dark in winter.
So even if your alarm clock says sevenm.
\"You look outside and your eyes may say no, my biological clock tells me to go back to bed and it\'s dark outside,\" he said . \".
\"Especially in winter, we didn\'t receive the morning light signal because it was too dark.
You always feel out of sync.
\"Others have found that this is not about the length of daylight, but how bright it is.
\"I already have some patients reporting that it will be eliminated if the winter is really sunny (depression)for them.
\"I don\'t know there is a model that works for everyone,\" said Tam . \". 3.
Is the rainy weather in Vancouver worse than elsewhere?
\"They have not yet found strict patterns of rainfall associated with more grief,\" said Tam . \".
\"The funny thing is, in my practice, someone swears when they come to B. C.
Vancouver, for example, Ontario.
Back to the east, the weather was much clearer and there was a lot of snow on the ground, so it was double bright.
Snow reflects light.
Tam said the survey showed that while fewer Florida residents were suffering from grief, as many as 10 per cent of Alaska showed symptoms.
Studies in Canada have shown that the number of patients is between 1 and 3 percentage points.
As many Canadians suffer from mild winter depression.
\"A lot of people will go through a winter depression themselves. ” 4.
The most common treatment?
\"Use light boxes or simple books brightly --
\"Light therapy is done in the morning,\" said Tam . \".
\"First of all, it makes the day longer and also gives you a signal for the morning.
Tam said that some patients who did not have time to take half an hour under the lights every day were prescribed anti-depression drugs.
Specially designed light boxes reduce the symptoms of people using light boxes from 60 to 100 at a cost of between 300 and US dollars.
\"They are much brighter than the lights in the room,\" said Tam . \".
The intensity of the indoor lights is between 600 and 700 Lux, while the light box used for SAD treatment goes out 10,000 lux.
You are not advised by the doctor to make your own lights.
The lights are shielded so that they do not emit UV rays.
\"We want it to be bright, but don\'t tan your skin.
\"The summer sun at noon can be as high as 100,000 lux,\" said Tam. 5.
What should I do if I think I\'m sad?
Everyone who is obviously depressed should be assessed by a family doctor because of some physical problems (
Such as thyroid disease)
Can be shown as depression.
A person with grief can be treated by a family doctor, referred to a psychiatrist, or (in Vancouver)
Ask Tam and his colleagues at UBC for further evaluation.
After the assessment of qualified health professionals, people should not treat themselves with light.
Remind people not to use sunbathing studios to treat grief.
The effect of light therapy is through the eyes, not through the skin, and due to the harmful effects of ultraviolet exposure, one should not open his eyes at the tanning booth.
