Dr. Margaret Austen B.A. (Hons. Psychology) PhD in Psychology Admitted to Doctor of Philosophy, December 2003 University of Tasmania, Hobart Winter Blues, also known as Seasonal Affective Disorder (SAD) is prevalent in locations of greater than 40⁰ N or S. Circannual biological rhythms are disrupted creating variations across the seasons to mood, sleep and eating patterns, and motivation. Vulnerability to changes with the seasons will be discussed as well as some self- help ways to overcome it. Emotions, energy level and performance have also been shown to vary with the seasons without any mood changes . AETIOLOGY • Prevalent in a high percentage of the population at latitudes of greater then 40 degrees N or S. • Known to have a biological basis • Thought to be the reduced amount of light each day in autumn and winter that disrupts circadian rhythms and biochemicals/ neurotransmitters •recurrent autumn/winter mood variations • hypersomnia, fatigue •carbohydrate cravings, weight gain • social withdrawal • lack of energy, unmotivated, concentration difficulties 11 Mean hours of sleep 10 9 Control S-SAD 8 C-SAD 7 6 Winter Spring Summer Autumn What are the risk factors that predispose people to getting SAD? What is it like to have the winter blues, as opposed to SAD with extreme depressions? How common is it? 1. Inherent vulnerability SAD runs in families, women more likely, ethnic groups? survival of the fittest, hunter-gatherers, symptoms of SAD are energy conserving, e.g., hibernating bears, squirrels, failure of intrinsic factors to cope with seasonal change 2. Light deprivation – style of home, elderly, grey days, those living in country, dark buildings 3. Stress – Demands of work don’t change with the seasons, stressful circumstances, relationship difficulties, etc Understanding SAD, and your own cyclic seasonal pattern of symptoms Changing the environment, the value of light, sun and warmth Holidays, Relocation Exercise, diet Pamper yourself, massage, warm spa, listen to music Stress management Avoid major decisions during winter Understand that what they are going through is real. Hear their pain, empathise with them No cliches! e.g., “oh, it’s all in the mind!”, “there’s always someone else worse off!”, “you need a good kick in the . . . To get you going!” Not helpful to point out there’s dust or the floor’s not swept, big pile of ironing etc. Helping them isn’t helpful – they’ll feel guilt and shame. You’ll feel more needed if you care for them rather than to reward yourself or pat yourself on the back Take them out for lunch (hearty soup?) or a walk in the park. Alternatively give them a pot of soup and/ or garden flowers If you feel they aren’t coping – ask them would they seek assistance Listen for any suggestion of suicide. SAD, WINTER BLUES autumn/winter depression MAJOR DEPRESSION Major Depressive Disorder hypersomnia insomnia overeating undereating weight gain weight loss low arousal e.g., sullenness high arousal e.g., anxiety • When should you consider entering therapy? a. Difficulty getting to work on a regular basis b. Marked reduction in your ability to think and concentrate c. Difficulty performing tasks that you could previously manage • Light Therapy • Psychotherapy • Cognitive Therapy • Behaviour Therapy • Anti-depressant Medications • Combined Therapies Tension and Effort Stress Inventory• Participants overall showed less relaxation, excitement, and placidity; and more anger, sullenness, humiliation, shame and guilt during the A/W months compared to S/S months. • The 2 SAD groups felt less relaxation and excitement, and more anxiety and anger than controls. Regardless of emotion, the SAD groups rated negative emotions greater than control participants Motivational Style Profile • Controls showed decreased measured for emotionality/ effortfulness in winter as compared to summer. All participants showed greater optimism than pessimism. • Regardless of group, all subscales showed more extreme measures for summer than winter. Stressor Scale All participants rated greater stress level following a stressor task (amithmetic) than priod to the task, but SAD groups reported stress greater in the A/W months Metabolic symptoms: • All participants report greater fatigue, as well as a lesser quality sleep in June • Tendency to crave carbohydrates in A/W, though greater for SAD groups than for controls. Cognitive Impairment: • Deficits to psychomotor speed, concentration, abstract thinking, and accuracy, IQ STM numerical tasks. Unclear whether impairment is related to neurophysiology or as a result of depressed ideation. • No differences shown on a verbal IQ task • RVF/ LH – verbal: LVF/ RH – spatial. Slowed reaction time to RH spatial task in winter months may relate to a competion between emotion and response time in the RH. Connection between seasonality, melancholy, and creativity • • • • • • • “No great genius was without a mixture of insanity”Aristotle, 12th C. Composers: Handel, Mahler, Schumann Artists: Michaelangelo, van Gogh Writers: Milton, Poe, Hemingway, Wolfe, Dickinson Politicians: Lincoln, Churchill Comedian: Spike Milligan Emphasis on winter themes: cold, black bile, death and gloom i comparison to spring themes: life, sunny, fragrant, cheeriness • • • • First named in Maryland, US in 1974 In early history, physicians emphasised the effect of the seasons on all illness, taught by Hippocrates (460-370 B.C.), known as the father of medicine In early 1st C. A.D., Galen saw emotion to be the result of biological processes, first to report association between lethargy in seasonal depression and hibernation Seasonality fell into disfavour mid 20th C when biological and medical theories dominated medicine “See! Winter comes, to rule the varied Year, Sullen, and sad.” From “Winter”. James Thomson, 1726 “To everything there is a season and a time to every purpose under heaven” Ecclesiastes 3:1 “. . . . . cold weakens the mental activities. This is evident in animals which are forced by the frost to hibernate” Galen (129-200 A.D.) (Galen, trans., 1976) “Ah, woe is me! Winter is come and gone, But grief returns with the revolving year.” Percy Bysshe Shelley Cont. There’s a certain Slant of light, Winter afternoonsThat oppresses, like the Heft Of Cathedral TunesHeavenly Hurt, it gives usWe can find no scar, But internal difference, Where the Meanings, are. We grow accustomed to the DarkWhen Light is put awayAs when the Neighor holds the Lamp To witness her Good-bye-… Either the Darkness altersOr something in the sight Adjusts itself to MidnightAnd Life steps almost straight. Emily Dickinson, 1830-1886 SAD has symptoms of mood variation, along with hypersomnia, overeating, weight gain, lack of motivation and decreased energy Thought to be the shortened daylight hours that create disruption to circadian rhythms and many physiological, biochemical, and psychological functions Vulnerability includes inherent factors, light deprivation and stress Ways for self help include gaining light/ sun, exercise, carbohydrates/ high protein diet Important to seek further help if not coping a day to day basis Non seasonal people still show some variation to sleep patterns. Motivation, stress, energy level and cognitive performance have been shown to vary with the seasons
