Seasonal Affective Disorder (SAD) is a form of depression tied to seasonal changes, most commonly appearing during fall and winter months when sunlight is limited and days feel shorter. While many people brush off these symptoms as part of the season, SAD can significantly impact daily life, mood, motivation, and overall well-being. The good news is that it is a treatable condition, and there are multiple approaches that can help provide relief.
Why SAD Happens
Researchers are still uncovering the exact mechanisms behind seasonal affective disorder, but we do know that sunlight plays a major role. Less daylight means:
- disruption in circadian rhythms (our internal 24-hour clock)
- changes in serotonin (our mood-regulating neurotransmitter)
- reduced vitamin D levels (linked to both mood and immune function)
For some, winter is simply harder to navigate. Shorter days, cold weather, and limited outdoor activity can layer on top of stress, work, and family responsibilities. While SAD is most commonly experienced in the winter months, it can occur with different symptom patterns during the spring or summer as well.
Common Symptoms of SAD
Seasonal affective disorder can look similar to other forms of depression, but certain SAD symptoms are more season-specific, including:
- low mood or irritability
- fatigue or heavy “winter sluggishness”
- changes in sleep (often oversleeping)
- difficulty concentrating
- cravings for carbohydrates or sugar
- feeling disconnected or withdrawn
- loss of interest in activities once enjoyed
For many people, symptoms begin mildly as days get shorter and intensify as winter progresses. There is a link between the severity of symptoms and environmental changes.
Treatment Options for SAD
The best approach to SAD treatment depends on the person, symptom type and severity, and how long symptoms have been present. Here are the most common and evidence-backed treatment avenues:
Light Therapy
Light therapy involves sitting in front of a bright light box (typically 10,000 lux) for 20–30 minutes daily. It’s designed to mimic natural daylight and help regulate circadian rhythms. Light therapy is considered first-line for winter depression and can be especially helpful for those who notice energy dips or morning sluggishness during colder seasons.
Vitamin D Support
Low vitamin D levels are common during winter months and may contribute to mood changes. Vitamin D and depression research suggests that correcting deficiencies can support better energy and mental clarity, especially in individuals with limited sun exposure. While not a standalone cure for SAD, it often functions as a useful piece of the puzzle.
IV Hydration + Nutrient Support
IV hydration may help support seasonal depression by supporting hydration, electrolyte balance, and vitamin needs. IV therapy may help address low vitamin D levels, nutrient deficiencies, and low energy. Many people report increased energy, improved mental clarity, and fewer “winter slump” symptoms following treatment. Because IV therapy bypasses the digestive system, nutrients are fully absorbed into the bloodstream and utilized more efficiently. Learn more about our IV Infusion options.
Ketamine for Seasonal Affective Disorder
A more recent and promising option for treating SAD is ketamine therapy. Ketamine works differently from traditional antidepressants by targeting glutamate pathways and promoting neuroplasticity, which helps the brain adapt and form new connections. Ketamine for SAD may provide more rapid relief compared to SSRIs, which can take weeks to take effect, making it a compelling option during a short seasonal window.
At Evansville Ketamine, we offer ketamine treatment for seasonal affective disorder and other forms of depression. Many patients seek ketamine therapy when symptoms intensify suddenly during winter or when other treatments haven’t offered enough relief. Ketamine has been explored as a rapid relief depression treatment, especially for individuals with moderate to severe symptoms.
Don’t Brush Off SAD
SAD may be seasonal, but that doesn’t make it minor. If you notice patterns year after year of feeling low, withdrawn, tired, or unlike yourself, it’s worth addressing. With treatment, support, and the right tools, it is possible to feel better through the darker months.
