For those dealing with Seasonal Affective Disorder (SAD), increasing your intake of Vitamin D can be a game-changer for improving both mood and daily functioning. During the colder, darker months, many individuals with SAD experience feelings of sadness, fatigue, and a lack of energy, which often leads to disrupted sleep patterns and a decrease in appetite. The “winter blues” can feel overwhelming, making it harder to stay motivated and enjoy your usual activities.
So, can Vitamin D for Seasonal Affective Disorder help combat these wintertime struggles? Absolutely. Vitamin D plays a crucial role in boosting overall well-being by supporting healthy serotonin levels in the brain. This essential nutrient has been shown to lift mood, promote feelings of positivity, and help reduce the emotional and physical toll of seasonal depression.
As daylight hours shrink, particularly in areas with long winters like Alaska, the body’s natural production of Vitamin D declines, making supplementation especially beneficial. Adding Vitamin D to your routine can help you maintain a more balanced mood, improve energy levels, and keep your spirits up through the darker months.

What is Seasonal Affective Disorder?
Seasonal affective disorder (SAD) is a type of depression that happens due to changes in seasons, such as early winter or late fall. It is often associated with winter blues where people feel a bit down after being stuck inside with little to no exposure to sunlight.
The disorder is known to begin in adolescence or early adulthood and usually occurs more often in women than in men. It should be noted that “cabin fever” or just the plain “winter blues” are not to be confused with SAD. According to the National Institute of Health, people who reside in locations with long winter nights are not necessarily more likely to have SAD.
Symptoms of SAD include:
- Afternoon slumps with decreased energy and concentration
- Increased appetite with weight gain
- Trouble sleeping or insomnia
- Excessive daytime fatigue
- Lack of energy
- Loss of interest in work and other activities
- Slow and sluggish
- Lethargic movement
- Social withdrawal
- Unhappiness and irritability
Differences between regular depression and SAD as far as symptoms are concerned include weight loss as opposed to weight gain and problems sleeping instead of increased sleep.
Causes of SAD
Research suggests that the causes of SAD are linked to depression. Although the primary cause of SAD is unknown, there are some contributing factors, including ambient light, body temperature, and hormone regulation.
Hormone Regulation
Seasonal Affective Disorder (SAD) is often linked to lower melatonin levels, though it’s not the primary cause. Melatonin is a hormone produced by the pineal gland in the brain, playing a vital role in regulating the body’s circadian rhythm—a 24-hour internal “clock” that governs sleep-wake cycles and other important functions, like mood and energy. During the darker winter months, reduced exposure to natural light can disrupt melatonin production, which in turn affects sleep quality and overall well-being.
While melatonin imbalances contribute to the symptoms of SAD, it’s just one piece of the puzzle. In areas with long winters, the lack of sunlight can disrupt serotonin levels and your circadian rhythm, making it harder to stay energized and upbeat. Strategies like light therapy can help restore the balance of melatonin, reset your internal clock, and improve both sleep quality and mood, providing a much-needed boost during the darker months.
Less Sunlight Exposure
When the world outside is dark, your body naturally produces more melatonin, the hormone that helps you relax and prepare for sleep. As daylight returns, melatonin production drops, signaling to your body that it’s time to wake up and get moving. This delicate balance of light and dark is essential for maintaining a healthy sleep-wake cycle and keeping your circadian rhythm in sync.
However, disruptions in this natural process—such as exposure to bright lights in the evening or not getting enough sunlight during the day—can throw your melatonin production off course. This imbalance can lead to sleep difficulties, fatigue, and mood disturbances, which are common symptoms of Seasonal Affective Disorder (SAD).
In regions with long winters or extended periods of darkness, like Alaska, this disruption can be particularly pronounced, making it even more important to regulate light exposure throughout the day to support your body’s natural rhythms and promote better sleep and overall well-being.
Lack of Social Interaction
Isolation can be a significant trigger for those dealing with Seasonal Affective Disorder (SAD), often causing individuals to retreat into themselves, much like the hibernation instincts of animals during the colder months. This tendency to withdraw from social interaction is common, as the gloomier days can make even the simplest social interactions feel overwhelming. However, this sense of isolation only intensifies feelings of sadness and disconnection, making it even harder to lift your spirits.
It’s crucial, especially during the long winter months, to actively seek out the company of others to maintain a positive outlook. Social connections help keep the mind engaged and uplifted, providing much-needed emotional support.
Whether it’s spending time with family, joining community events, or simply checking in with friends, surrounding yourself with the warmth and presence of others can be a powerful antidote to the isolation that often accompanies SAD. By fostering these connections, you can help balance the darker, more solitary days with moments of joy and shared experience, ultimately boosting your mood and helping to combat the effects of seasonal depression.
Effective Ways to Deal With SAD
There are various ways to conquer SAD, including exercising regularly and maintaining a balanced diet. Meanwhile, light box therapy is an effective SAD treatment where people having depressive episodes can get ample sunlight from specially designed lamps that can emit the right amount of light the body needs.
Exercise Regularly
Regular exercise is one of the most effective ways to manage the symptoms of Seasonal Affective Disorder (SAD), but it can be challenging to maintain a routine, especially during the long, cold winter months. When the days are short, and the temperatures drop, stepping outside for physical activity might feel daunting, but staying active is key to boosting both your physical and mental well-being.
If outdoor exercise feels too overwhelming, plenty of indoor alternatives can still make a significant impact. A simple yet effective way to stay active is by walking around an indoor mall—aim for four to five trips around the space, which can be equivalent to a brisk walk outside. Alternatively, consider joining an affordable local gym or community center where you can access fitness equipment and classes without committing to an expensive membership.
Keep a Positive Outlook
While the cold, dark days can take a toll, maintaining a hopeful perspective can make all the difference. Dr. Christian Holle, an associate professor of Psychology at William Paterson University, suggests a simple yet powerful mindset shift: “You must keep thinking that winter is almost over and that spring and summer will be here very soon.”
Holding onto the idea that brighter days are ahead can help ease the weight of winter and provide a sense of anticipation for the renewal that spring brings. Every day you push through winter’s challenges, you’re one step closer to the light and warmth of sunnier months.
Take Vitamin D
Registered Dietitian Karen Goldberg from the YM-YWHA of North Jersey in Wayne emphasizes the importance of Vitamin D supplementation, especially for individuals struggling with SAD. She explains that many people, even without SAD, don’t get enough Vitamin D on a daily basis, making supplementation all the more important during the darker months when sunlight is scarce.
“Typically, 400 international units (IU) of Vitamin D are recommended for most people,” Goldberg shares. “However, as research continues to evolve, many doctors now suggest that a daily intake of 1,000 to 2,000 IU is even more beneficial, particularly for those with SAD.” Incorporating Vitamin D into your daily routine can make a significant difference, improving your overall well-being and helping to restore balance during the darker months.
Consult a Mental Health Professional
Dr. Christian Holle, an expert in psychology, advises that if symptoms persist and begin to interfere with your daily life—especially work or relationships—it might be time to speak with a healthcare professional.
Seeking guidance from a doctor or therapist can help pinpoint the root cause and provide the tools necessary for managing the condition effectively. For those who have loved ones showing signs of SAD, it’s crucial to keep a close watch on their mood, particularly when it starts to decline.
As Dr. Holle points out, “Thoughts of suicide should especially be paid close attention to, although warning signs can be subtle.” Recognizing these early signs and encouraging open communication can make a world of difference, ensuring that support is in place when it’s needed most.
Frequently Asked Questions
Does Vitamin D help seasonal depression?
Vitamin D plays an important role in balancing out serotonin, the hormone responsible for producing positive emotions. During winter, your Vitamin D levels decrease, making you feel random bouts of sadness.
Does Vitamin D help solve insomnia?
If you lack serotonin, you are also insufficient in melatonin, which regulates sleep-wake cycles. Having increased Vitamin D levels can help avoid mood changes and control sleep patterns, thus reducing SAD symptoms.
How do I include Vitamin D in my diet?
A proper intake of Vitamin D can be found in certain types of fish, including salmon, which has 794 international units; Mackerel (388 international units, but is high in mercury); and tuna fish, which has 302 international units. At least three ounces should be digested to acquire the necessary amount of Vitamin D.
Fatty fish and fish oils are very important to your daily diet. You can also take a tablespoon of Cod Liver oil daily, although it’s usually not the first choice of taste. A multivitamin or Vitamin D on its own is also helpful as is dairy-based products such as milk or yogurt fortified with Vitamin D.
What is the best source of Vitamin D?
Most foods contain Vitamin D but are inadequate to treat SAD. It’s best to get it from sun exposure or supplementation.
Does light box therapy help the body produce Vitamin D for SAD?
Yes, sitting in front of a specialized lamp can help your body get the Vitamin D it needs from the sun. At Alaska Northern Lights, we have different types of light boxes for people suffering from SAD, winter blues, and depression.
