SAD? Or just blue?

PeaceWinter2By Dr. Micaela Wexler

Are you feeling the post-holiday let down? After all the parties are over and the guests have left, many people feel anxiety, disappointment and depression. That is normal.

However, if you are feeling depressed, tired, weak, achy or ANGRY, you might be SAD
The “winter blues” might be something more: you might have SAD – Seasonal Affective Disorder. This is a type of depression that occurs every year during the winter months. It’s not just the “winter blues,” which is a feeling of mild disappointment and irritation most people get as they cope with the challenges of winter.

How do you know if you’re SAD and not just blue?
People with SAD feel the following:
- worthless, guilty, tense
- fatigue
- down and depressed
- arms and legs feel heavy, achy
- increased headaches
- irritable
- worried, increased checking behavior
- indecisive
- increased urination, heart palpitations, stomach aches
- difficulty focusing
- suspicious, paranoid, think co-workers don’t like them
- increased difficulty starting the day
- increased insomnia

These symptoms go on for at least two weeks at a time and can recur. They start in late fall and fade away in early spring.

It isn’t in your head. Well, actually, it is: it is caused by your hypothalamus, a part of your brain, secreting more melatonin when your eyes are exposed to less sunshine. So, if you’re having insomnia, don’t take melatonin. When light hits are eyes, melatonin starts to go down.

There is also a decrease in serotonin caused by a decrease in physical activity. An additional contributing factor is the disruption of your circadian rhythms by the change in weather, shorter days and change in routine. Many people first notice these symptoms following the time change.

There are some dangerous symptoms you should not ignore:
- feeling suicidal, or feeling that life just doesn’t matter – get help right away
- irritability leading to behavior that is out of character: yelling at co-workers, engaging in physical fights or road rage
- social isolation that is out of character – missing the company holiday party even though you are known as a social person, for example

Why you shouldn’t ignore it:

- Decreased focus can lead to problems with work, increased debt, child neglect
- SAD can become major depression
- suspicious thoughts can cause irreparable harm: premature termination of a job or relationship. Many people file for divorce during these months.
- your immune system can become depressed

Treatment is easy and effective
- Increase physical activity – increases serotonin levels
- Watch your diet: beware of giving in to carb craving; eat more nuts and fruits – maybe this is why fruitcake is a traditional fruit at this time of year
- Eat more walnuts – have been shown to help make you less SAD
- Make home brighter
- Bundle up and step outside – nothing makes your home feel warmer than stepping in from the cold
- Light box therapy
Does light therapy work?

Yes. it is supported by at least two meta-analyses. It also works for non-seasonal depression. Most companies will your refund money in 30 days if symptoms don’t decrease.

What type of light works?

Bright sunshine in the morning works best – not available in the winter time
10,000 lux for 30 minutes
5,000 lux for 60 minutes

Light boxes – what to look for:

- beware of blue light – not proven to be effective, may cause macular degeneration
- light must shine in your face
- 10,000 lux – 30 minutes
- research shows the bigger the better, less lux requires longer exposure

Look at lux distance
- 22 inches: normal distance from computer when working
- 28 inches: distance from computer when you lean back in the chair

Dawn stimulators:
- require longer exposure
- effective – eyes more sensitive in the morning
- help reset sleep-wake cycle
- convenient – can use in bedroom

And, I can’t stress this enough, if you feel suicidal, please call 911 or go to the emergency room.
