There’s something that goes around every year, and it affects roughly 10 million Americans.
Seasonal Affective Disorder, or SAD, is a type of depression that shows up as the days get shorter with less daylight, with places located far from the equator, like Alaska or Canada, experiencing a higher prevalence of SAD.
While the cause of SAD isn’t completely known, it likely has to do with our sleep-wake cycle. Lack of sunlight during the shorter days of fall and winter can disrupt our circadian rhythm, which is responsible for regulating sleep, this change can decrease the body’s levels of serotonin, a brain chemical that affects mood. Additionally, increased darkness can increase a sleep-regulating hormone called melatonin, which can cause sleepiness and fatigue.
While adults are more affected, it’s important to recognize that students can be affected by SAD as well. Although the symptoms of sluggishness and feeling down are similar in children, they might present differently. For example, kids may feel irritable, grumpy, or angry instead of feeling sad. They may have trouble falling or staying asleep, which can result in trouble concentrating in school or losing interest in social activities they enjoy. Any mental illnesses the student might already live with may be worsened during times of reduced sunlight.
Watch out for the kiddos who seem “off,” sluggish, or excessively grumpy; their mental health might be challenged by SAD. As an educator, you’ve taken the first steps to support students with SAD by reading this blog! Other ideas include recognizing the signs, being flexible with assignments and due dates, and integrating movement breaks to restore balance and energy. Encourage physical activity in small doses, along with healthy eating.
Through empathy and understanding, we can help our students through this tough time of the year!
