Why Am I S.A.D.?

Today’s guest blog was written by Kathleen Corcoran

The cold is pressing in, the days are short and dark, and colorful gardens are sleeping and gray. It’s easy to get a case of the Winter Blues, but you might also be dealing with something a little more insidious – Seasonal Affective Disorder. If you notice a pattern of depressed moods at the same time every year, you might have S.A.D.

What Causes Seasonal Affective Disorder?

Also known as S.A.D., this subset of mood disorders causes depressive symptoms at the same time every year. Unlike regular depression, S.A.D. comes and goes regularly with the changing seasons.

Though winter-pattern Seasonal Affective Disorder is more common, some people suffer from the mood disorder in the summer. In both varieties, the change in mood coincides with the change in temperature and length of daylight.

The causes of S.A.D. are not entirely clear, but researchers believe it may be related to serotonin, melatonin, or Vitamin D levels. Some scientists believe the change in daylight hours interferes with the brain’s ability to absorb serotonin. Others point to changes in daylight hours messing up melatonin and sleep schedules. Another common hypothesis is that lack of sunlight causes a vitamin D deficiency, leading to mood disruptions.

Other factors that may contribute to winter-pattern S.A.D. include environmental causes. Cold weather often forces people indoors, curtailing opportunities for exercise and social interaction. Fresh fruits and vegetables are less accessible, and those available in grocery stores are generally less nutritious after being force-ripened or shipped long distances. Winter holidays might also contribute to S.A.D., both in the stress leading up to them and the letdown after they’ve passed.

Symptoms of S.A.D.

The symptoms of S.A.D. are very similar to those of general depression, including empty moods, lack of energy, and loss of interest in usual pleasures and hobbies.

In addition, winter-pattern S.A.D. often includes symptoms that make the sufferer look a bit like a hibernating bear:

  • Oversleeping
  • Overeating, particularly of carbohydrates, leading to weight gain
  • Social withdrawal (feeling like “hibernating”)

On the other hand, summer-pattern S.A.D. can cause symptoms that are nearly the opposite:

  • Trouble sleeping
  • Poor appetite, leading to weight loss
  • Restlessness and agitation
  • Anxiety
  • Violent or aggressive behavior

S.A.D. History

Knowledge of Seasonal Affective Disorder goes back at least 2500 years! The Greek physician Hippocrates (c 460-377BCE) noted the correlation of seasonal changes and both mania and melancholia all the way back in the 4th Century BCE. Aulus Cornelius Celsus (c 25BCE-50CE) blamed bad weather for a spike in melancholia, madness, and epilepsy.

Some ancient physicians recognized the role of sunlight in treatment for S.A.D. The Greek physician Aretaeus of Cappadocia suggested treating lethargics by laying them in the light and exposing them to the rays of the sun.

Fast forward a few thousand years, psychiatrist Norman Rosenthal noticed that his moods fluctuated much more in the winter after moving from South Africa to New York in 1976. He conducted a study with the National Institute of Health on the relationship between melatonin, light, and mood. In 1984, the NIH research group published the results of their study, naming Seasonal Affective Disorder for the first time in print. The American Psychological Association recognized S.A.D. in 1990 as a mental disorder.

Since that time, many advances in science and medicine have created more effective S.A.D. treatments. Scientists were able to make full-spectrum lamps all the way back in the 1920s, with a combination of incandescent and fluorescent bulbs, but those bulbs are now easier to make and more effective to use. New anti-depressant medications have had promising results in trials for treating Seasonal Affective Disorder. People with S.A.D. can now download phone apps to track circadian rhythms, monitor hormone levels, or set a morning alarm that gradually increases light to mimic dawn.

S.A.D. Treatment

Treatment for Seasonal Affective Disorder overlaps in many ways with treatment for other forms of depression. However, the external factors involved in S.A.D. mean that there are some different options. For one thing, the seasonal nature may allow those affected by S.A.D. to anticipate and prepare for changes before symptoms start to occur.

  • Light therapy
  • Dawn simulators
  • Maintaining a regular sleep schedule
  • Exercising outdoors or next to a window
  • Seeking out socialization
  • Psychotherapy
  • Antidepressant medication
  • Vitamin D supplements

LET THERE BE LIGHT

As the Winter Solstice approaches, many people are feeling a little low—or a lot.  Fortunately, there are several holidays and celebrations around this time of year to add a little light to your schedule. Here are just a few:

Diwali or Deepawali is a festival of lights celebrated by Hindus, Sikhs, and Jains. It is celebrated in mid-October to late November, according to a lunar calendar.

Hanukkah is a Jewish festival of lights celebrated in November or December, according to the Gregorian calendar.

Kwanzaa is a celebration of culture and community celebrated in late December. An important part of the celebration involves lighting the kinara.

Lussevaka or Santa Lucia Day is a celebration of light, community, and the triumph of good over evil. It is primarily celebrated in Sweden, but St Lucia festivals are also held in Croatia, Italy, France, Germany, and Norway on December 13.

Yule is celebrated in many different ways by Pagans and Wiccans. It is the celebration of the Winter Solstice, the return of the sun. This is often symbolically represented by burning a Yule log, signifying the rebirth of the Oak King and waning of the Holly King.

Don’t Be SAD

There is a term for those who suffer most when the days grow short: SAD (Seasonal Affective Disorder).  SAD increases in higher latitudes where the winter days are short. Light therapy, where you arrange a special wide-spectrum light therapy box device at an angle to your face. Using such a device for several hours at the same time every day can be used to treat SAD. It can also help treat those who have depression all year round, improving their overall well-being.

Anger management therapy can sometimes be combined with light therapy.

Scientists have also discovered that light therapy can lower nighttime agitation in Alzheimer’s patients and reduce symptoms in Parkinson’s patients, including sleeping problems and tremors.

Whether sick or healthy, light definitely affects your mood. According to research, one in four people in Alaska suffers from depression – and it’s mainly caused by a lack of sunlight.

Sunshine Cures Everything

Sunshine can also help with pain control. Research shows that patients whose beds are on a sunny side of a hospital experience less pain than those whose rooms are in the shade. As well as reduced pain, patients in sunny rooms tend to recover sooner, use fewer painkillers, and feel less stressed. One theory is that exposure to sunlight releases serotonin: a feel-good chemical in the brain.

High solar activity has been found to increase fertility rates. Furthermore, light can also give men a boost in the bedroom. Research has shown that higher testosterone is boosted by Vitamin D. The biggest source? The sun. A light box would have the same affect, but is possibly less romantic than a sunny picnic or stroll along the beach.

As far as I can tell, the health benefits of sunlight are all attributed to Vitamin D effects on/in the body.

Fake Light

Aside from the health benefits of light, many practical applications have lead to the creation of light when there is no sun—primarily the benefits of being able to see in the dark! 

Over the centuries, we’ve seen many advances in created light.

Until the 20th century, candles were most common in Northern Europe. In Southern Europe and the Mediterranean, oil lamps predominated.

Besides providing light, candles were used for the purpose of measuring time, usually in hours. The Song Dynasty in China (960-1279) used candle clocks.

A version of a candle clock is often used to mark the countdown of the days leading to Christmas. This is called an Advent candle.

Note: This term is also used for candles that decorate an Advent wreath.

Among the earliest forms of created light, candles have had the greatest staying power into modern times for numerous uses. An estimated 1 billion pounds of wax are used in the candles sold each year in the United States.

FYI: No candle wax has ever been shown to be toxic or harmful to humans.

As the days grow shorter and night falls like a rock earlier and earlier, many people light candles around the house, even when they have electric lights, simply because the warm glow is cheerful. Which brings us back to human craving for light!

Cold Light

Gas lights were developed in the 1790s and were in common use in large cities by the middle of the nineteenth century. Streetlamps made the night safer (in wealthy areas) and gas piped into houses allowed (wealthy) homeowners to ignore the setting sun.

Too bright!

The invention of the electric-powered incandescent light bulb was even more effective in making the sun obsolete. Since electric lights have become nearly universal, ideas like a 24 hour workday and cutting sleep to work more have become nearly as universal.

Newborn incubators, refrigeration, pacemakers, surgical lighting, heated houses, underground ventilation, and electric harp string tuning meters are undoubtedly beneficial to human society. However, humans in general have become increasingly sleep-deprived and overworked since the spread of electricity. Heated and lighted houses have also made humans more likely to stay indoors all winter, avoiding direct sunlight. This leads right back to the beginning of this blog – Seasonal Affective Disorder.

Bottom line: Humans need light for a multitude of reasons, and in a multitude of forms.

Massive forest fires can’t stop Oregoners from playing golf. Maybe it’s not giving off enough light.
