Feeling the “Winter Blahs”? Understanding Seasonal Affective Disorder
If you’re currently in the Northern Hemisphere, you might be noticing a familiar, heavy feeling. It’s that “blah” sensation that creeps in between the fall and spring equinoxes. Even though the days are technically getting longer after the winter solstice, the early darkness, the biting cold, and the layers of heavy clothing can take a significant toll on your mental and physical well-being.
This isn’t just “the winter blues” – for many, it is Seasonal Affective Disorder (SAD), a type of depression that relates to changes in seasons. Over my 15 years of practice and working with over 5,000 patients, I’ve seen how this seasonal shift impacts metabolism, immunity, and emotional health.
The good news? You don’t have to wait for the spring thaw to feel better. By understanding the physiological “why” behind these feelings, we can implement strategies to reclaim our energy.
1. Seasonal Nutrition: The Ancestral Case for Reducing Carbs
The first place we must look is the dinner plate. Interestingly, from an ancestral perspective, humans weren’t designed to consume high amounts of carbohydrates during the winter.
Why Biology Favors Fats and Proteins in Winter
Thousands of years ago, nothing grew in the winter. Our ancestors relied on dried stores, healthy fats, and proteins from hunting. When we consume refined carbohydrates and sugars during the winter months, we often experience “sluggish” metabolism and energy crashes.
- The Inuit Example: Populations in the far North traditionally subsist on high-fat, high-protein diets with almost zero carbohydrates, yet they maintain remarkable energy production.
- The Metabolic Shift: By reducing refined carbs and focusing on whole foods, you can stabilize your blood sugar and improve your mental clarity.
2. Vitamin D: The “Sunlight Hormone” and Immunity
Vitamin D isn’t just a vitamin; it’s a pro-hormone that plays a critical role in immunity, inflammatory response, and calcium absorption. During the winter, the sun’s angle prevents our skin from producing Vitamin D efficiently – and even if the sun is out, our skin is usually covered to protect us from the cold.
Knowing Your Levels
I recommend that everyone gets their Vitamin D levels tested. In my practice, I find that most people are insufficient (levels in the 20s or below).
- Optimal Range: Aim for 40–60 ng/mL (some practitioners prefer up to 80 ng/mL).
- Toxicity Warning: Vitamin D can become toxic if levels exceed 100 ng/mL. Always consult a provider before starting a high-dose regimen.
- The K2 Connection: If you supplement, look for Vitamin D3 with K2. Vitamin K2 helps ensure that the calcium absorbed by Vitamin D goes to your bones rather than your arteries. It can also help normalize your levels more quickly.
Research Note: A study published in the Journal of Nutrition suggests that Vitamin D receptors are located in areas of the brain involved in depression, suggesting a direct link between “D” levels and mood regulation.
3. Exercise: Stimulating Divergent Thinking
When we are in a depressed state, our thinking becomes “convergent” – we focus solely on the problem, feeling like we are staring at a locked door.
Exercise opens up divergent thinking. It stimulates the brain, increases blood flow, and fires up metabolic pathways that make us feel alert. By increasing your heart rate, you aren’t just burning calories; you are literally training your brain to see the “way around the wall” instead of just staring at the obstacle.
The Best Approach:
- If it’s a decent day, get outside. The combination of nature (a natural stimulant for divergent thinking), fresh air and movement is a powerful antidepressant.
- If it’s too cold, hit the gym. The change of environment is just as important as the physical exertion.
4. The Power of Human Connection (Oxytocin)
Winter often leads to isolation. Between the early sunset and the “flu season” scares, we tend to stay home and watch more TV. However, human connection is a physiological necessity.
Interacting with others releases oxytocin, often called the “cuddle hormone.” Oxytocin acts as a natural buffer against cortisol (the stress hormone) and can help dampen the heavy feelings associated with SAD. Whether it’s a gym class or a coffee date, don’t let the cold keep you from your community.
5. Quality Sleep vs. Quantity Sleep
You might find yourself sleeping 10 or 11 hours in the winter, yet still waking up exhausted. This is a red flag.
Longevity research consistently shows that the “sweet spot” for sleep is between 7 and 9 hours. Needing more than that often signals an underlying metabolic or inflammatory issue. To improve sleep quality:
- Avoid Blue Light: Turn off screens at least an hour before bed to allow melatonin production.
- Stay Hydrated: Winter air is dry; dehydration can lead to restless sleep. This becomes a bigger problem as we start to age – older people don’t hold onto their hydration as efficiently as younger people.
- Maintain a Routine: Go to bed and wake up at the same time to keep your circadian rhythm in check.
Bonus: Photobiomodulation (Red Light Therapy)
If you need an extra boost, consider Red and Infrared Light Therapy. These wavelengths help oxygenate tissues and can trigger the release of dopamine and serotonin – the “feel-good” neurotransmitters that are often depleted during the winter months.
Conclusion
The sun is coming back. Every day, the light lingers just a little longer. By adjusting your diet, checking your Vitamin D, moving your body, and staying connected, you can do more than just “survive” the winter – you can thrive through it.
