FEATURES fact or fiction? By Estelle Morrison W hile winter holidays can be a time of joyous family and friend gatherings, for some they can lead to unrealistic expectations, social withdrawal and professional and person- al stressors ranging from year-end work projects to over-spending and fi nancial stress. In addition, Canada's high latitude makes exposure to sunlight shorter, meaning peo- ple are much more likely to develop season- al aff ective disorder (SAD) than residents of more southerly countries. Canadian winters are infamously long and arduous and about three per cent of Canadians become so depressed and weary because of SAD that they are unable to carry their full work load in January and February. e performance of an additional 10 per cent is impaired to a lesser degree, accord- ing to the Mood Disorder Association of Ontario (MDAO). About two to six per cent of Canadians will experience the disorder in their lifetime, while another 15 per cent have a less severe experience described as the "winter blues." Causes, symptoms While scientists are still not sure about the exact causes of SAD, here is what the stud- ies show: Our body clock or circadian rhythm: Everyone has an internal body clock that dictates when to be awake or asleep. Less sunlight in the winter is thought to aff ect our circadian rhythm, bringing on symp- toms of depression. Melatonin levels: e body's release of the natural hormone melatonin is aff ected by the light/dark cycle. e change of sea- sons can disrupt the balance of melatonin, which may result in more moodiness and depression. Serotonin levels: Reduced sunlight can cause a drop in serotonin, a brain chemical (neurotransmitter) that affects mood. People who suffer from depression are known to have low levels of serotonin. Employees living with SAD can be pro- foundly impacted by the condition, result- ing in decreased productivity and increased absenteeism. Symptoms of seasonal aff ective disorder, according to the MDAO, include: • oversleeping — sometimes an increase of two to four or more hours per day • lethargy (low energy) • intense craving for carbohydrates • weight gain • withdrawal from social contacts • depressed mood occurring over at least two consecutive winters, alternating with non-depressed periods in the spring and summer. Adults are at a higher risk of SAD than children or teenagers. After the age of 50, the risk of SAD starts to decline. Women are up to eight times as likely as men to report having the disorder and it tends to run in families — most individuals with SAD have at least one close relative with a history of depression. People in northern countries are more likely to experience SAD than those who live closer to the equator because the days get shorter the further north you go. Preventitive measures by employers, employees Here are some ways both employers and employees can mitigate the eff ects at this time of year: • Get the facts — Read about SAD and other mood disorders. • Enlist the support of an EAP provider — If you have an employee assistance pro- gram, ask how it can help with informa- tion and consultations. Promote the EAP, emphasizing the service's confidential nature. • Help reduce stigma — Many employees will resist seeking help, fearing they will be found out and seen as weak. Some believe that disclosing mental illness could aff ect their job or career. Posters, brochures and workshops available from a local mental health centre or through an EAP can encourage help-seeking behaviour. • Review benefi ts and policies — Ensure that the plans include adequate support for mental health concerns. Determine if there is coverage for a light box, a com- mon treatment for SAD. Examine policies such as substance use, personal leaves and illness and disability to ensure they refl ect the needs of those suff ering from a mental health issue. Communicate those policies to employees regularly. • Address performance issues and ob- servable changes — Discuss changes in behaviour and performance-related con- cerns with employees. Let them know what is being observed and ask how you can help. (And while it is important for every manager to be on the lookout for behaviours affecting performance, attendance and interactions with col- leagues, they should keep in mind it is up to a health-care professional to make a diagnosis.) • Recommend exercise and exposure to light — Sun or box lamps are sold to brighten workspaces, though natural light is stronger and more therapeutic than artificial lighting. An employee who is particularly affected by sea- sonal depression should ask for a desk closer to a window. Research shows physical exercise is also important to head off the symptoms. Taking a walk outdoors before work or at lunch can provide the dual benefi ts of movement and natural light. Establish a lunch- time walking group or other outdoor activity. SAD can prevent suff erers from func- tioning normally, seriously limiting their personal and professional potential. But with education, an awareness of the symp- toms and early treatment, those living with SAD can lead productive lives while being productive at work.
