As winter’s icy fingers grip the country, some of us find ourselves diving into a vortex of lethargy and despondency. As much as we’d like the chilly season to be just about being in the blanket and sipping hot cocoa; for some, it is accompanied by Seasonal Affective Disorder (SAD). SAD is a form of depressive disorder that aligns itself with the seasons, primarily kicking in when autumn arrives and then lingering throughout the darker, colder months. The culprit? The sun’s elusiveness. With shorter daylight hours, our internal body clock gets haywire, messing up the levels of serotonin (our feel-good neurotransmitter) and melatonin (the hormone that regulates sleep).
Picture a constant battle against fatigue, a craving for carbs that goes way beyond mere comfort eating, and a severe lack of motivation. Add in some mood swings, irritability, and the insatiable need to sleep excessively— there is a high possible chance that it is SAD.
While it is more common in women, men can also be affected, and symptoms typically begin between the ages of 18 and 30. Women in their 20s and 30s seem to be particularly susceptible to this condition as they are more likely to experience fluctuating estrogen levels, which again, can affect the production of serotonin. Although, the reasons for this are not well understood.
The Key Triggers
Aditi Kumar, a counselling psychologist at Pause tells us that there are multiple factors that contribute to the development of SAD. Reduced exposure to natural light is a major cause, especially during the fall and winter months. The lack of sunlight affects the body’s internal clock, or circadian rhythm, disrupting the production of neurotransmitters like serotonin and melatonin. This can lead to decreased serotonin levels, which can influence mood regulation. In addition, lower light levels can disturb the body’s melatonin production, leading to disruptions in sleep patterns and contributing to feelings of lethargy and fatigue.
During colder months, people often engage in less physical activity due to harsh weather conditions and shorter daylight hours. Regular physical exercise stimulates the release of endorphins, neurotransmitters that can boost mood and reduce stress. A decrease in physical activity can lead to lower endorphin levels, worsening feelings of fatigue and low mood associated with SAD.
Dietary changes during winter months can also contribute to SAD and people may crave high-carbohydrate and high-sugar foods to feel comforted. While carbohydrates increase serotonin production, which can temporarily improve mood, excessive consumption of such foods can lead to energy crashes and weight gain, which can affect mood stability. Insufficient intake of certain nutrients, such as vitamin D due to reduced sunlight exposure, has been linked to an increased risk of depression and SAD, and can even impact mood regulation.
A skilled psychiatrist or mental health professional can diagnose SAD post conducting a thorough mental health exam and medical history assessment, after which the path to treatment and recovery gets clearer.
Management, Treatment, & Getting Better
Living with SAD can be tough, but there are a variety of effective treatments available to help you feel better.
SAD symptoms are similar to major depressive disorder, and exercise, nutrient-rich foods, and vitamin D are effective strategies for treating both. Regular exercise stimulates endorphin release, which combats lethargy and fatigue. Foods high in omega-3 fatty acids, like salmon and walnuts, have been linked to improved mood, while adequate vitamin D levels are essential due to reduced sunlight exposure.
While monitoring diet and exercise is important, mindfulness and stress reduction practices, such as meditation, yoga, and deep breathing exercises, can also help manage stress levels. These techniques promote relaxation and may reduce symptoms of anxiety or depression associated with SAD. If these feel a bit overwhelming, start small by picking simpler tasks such as walking around the house or a park, stretching in between work, are helpful too.
A commonly witnessed sign when someone is dealing with SAD is isolation. Maintaining social connections and seeking support from friends, family, or support groups can alleviate feelings of isolation and improve mood during the darker months. Therefore, it is important to stay connected and seek support when necessary.
Since lack of light is a key trigger for SAD, one of the primary strategies for combating SAD is increasing exposure to light. Light therapy, or phototherapy, involves using a light box that emits bright, artificial light mimicking natural sunlight. This exposure helps regulate the body’s internal clock and boost the production of neurotransmitters like serotonin, which influences mood.
To get the most out of a light box, it’s important that it provides exposure to 10,000 lux of light while producing as little UV light as possible. Ideally, it should be used within the first hour of waking up in the morning for about 20 to 30 minutes. Make sure to keep it about 16 to 24 inches (41 to 61 centimetres) from your face, and follow the manufacturer’s instructions about distance. While using the light box, keep your eyes open but avoid looking directly at the light.
