As the days grow shorter and temperatures drop, many people notice a shift in their mood, motivation, and overall energy. For some, these changes are mild and temporary. For others, they can develop into Seasonal Affective Disorder (SAD): a form of depression that follows a predictable pattern with the seasons, most commonly beginning in late fall or early winter and easing as spring returns.
At IntegriTMS, we see firsthand how seasonal changes can impact mental wellness. Understanding why this happens is the first step toward finding relief.
What Causes Seasonal Depression?
The biggest factor behind SAD is the reduction in natural sunlight during the winter months. Shorter days and longer nights can disrupt several important systems within the body:
1. Circadian Rhythm Disruption
Your internal clock relies heavily on light cues. When sunlight decreases, it can throw off your sleep–wake cycle and affect your mood and energy levels.
2. Serotonin Changes
Less sunlight can reduce serotonin, a neurotransmitter responsible for mood regulation. Low serotonin levels are strongly linked to depression.
3. Melatonin Increase
Darker days can trigger an overproduction of melatonin, the hormone that helps you sleep. Elevated melatonin can cause fatigue, oversleeping, and low motivation.
Common Symptoms of Seasonal Depression
While everyone’s experience is different, many individuals report:
· Persistent sadness or low mood
· Loss of interest in activities once enjoyed
· Increased sleep or difficulty waking up
· Low energy or chronic fatigue
· Carb cravings and increased appetite
· Difficulty concentrating
· Withdrawing from social activities
If these symptoms recur each year around the same time, they may indicate SAD rather than a temporary “winter slump.”
Who Is Most at Risk?
Seasonal depression is more common among:
· Individuals living in northern climates with long, dark winters
· People with a personal or family history of depression
· Those with limited outdoor exposure
· Individuals with vitamin D deficiency
· Women (who are statistically more likely to be affected)
Finding Support and Treatment
The encouraging news is that Seasonal Affective Disorder is highly treatable. Many people experience relief from lifestyle adjustments such as:
· Light therapy (using a specialized bright light lamp)
· Increasing outdoor time during daylight hours
· Regular physical activity
· Maintaining consistent sleep routines
· Engaging in counseling or talk therapy
For individuals who continue to experience significant symptoms or who struggle every winter despite these steps,Transcranial Magnetic Stimulation (TMS) offers an advanced, non-medication option.
How TMS Can Help
TMS is a non-invasive, FDA-cleared treatment that uses gentle magnetic pulses to stimulate the parts of the brain responsible for mood regulation. It helps restore healthier brain activity without medication side effects and is covered by most major insurance plans.
Many patients who experience seasonal or recurring depression find meaningful, lasting relief through TMS, especially when other treatments haven’t worked well enough.
At IntegriTMS, our team is dedicated to delivering compassionate, patient-centered care. We work with each individual patient to create a personalized treatment plan that supports long-term wellness, no matter the season.
If winter feels heavier than it should, you’re not alone.
Help is available, and brighter days are possible.
