Winter in the Pacific Northwest brings chilly mornings and shorter daylight hours—especially around the winter solstice on December 21, the darkest day of the year. This season also brings an increase in colds, flu, and overall immune stress.
The good news? Simple holistic habits, combined with supportive care like chiropractic, acupuncture, and massage therapy, can help keep your immune system strong all winter long.
How Winter Affects Your Immune System
As daylight decreases and temperatures drop, your body experiences a few key shifts:
- Less sunlight = lower Vitamin D levels, which can decrease immune function
- Colder weather tightens muscles and restricts circulation
- More time indoors increases exposure to viruses
- Holiday stress impacts sleep and weakens immunity
Research also shows that immune cells respond to circadian rhythms, meaning fewer daylight hours can influence inflammation and illness risk.
1. Chiropractic Care & Immunity
Chiropractic adjustments support the immune system by improving:
✓ Nervous System Function - Your spine protects the nervous system, which plays a major role in coordinating immune responses. When alignment is improved, nerve communication becomes clearer.
✓ Circulation & Lymphatic Flow - Adjustments reduce tension and improve mobility, helping lymph (your immune system’s drainage system) move more efficiently.
✓ Stress Reduction - Studies suggest that chiropractic care may lower stress hormones and support overall wellness.
Who benefits most? Anyone experiencing winter stiffness, stress, headaches, or poor sleep.
2. Acupuncture for Immune Support
Acupuncture has been shown to stimulate the body’s natural defenses in several ways:
✓ Boosts White Blood Cell Activity - Research indicates acupuncture may increase immune cell production and improve the body’s response to pathogens.
✓ Regulates Stress & Sleep - Chronic stress suppresses immunity. Acupuncture helps regulate cortisol, calm the nervous system, and promote better sleep—one of the most important factors for staying healthy.
✓ Improves Circulation - Warmer, healthier blood flow supports cellular repair and immune function.
3. Massage Therapy to Reduce Winter Tension
Massage isn’t just for relaxation—it plays a direct role in immune health:
- Reduces stress hormones like cortisol
- Increases circulation and lymphatic movement
- Improves sleep quality
- Helps loosen cold-weather muscle tension
4. Lifestyle Tips to Strengthen Immunity This Season
✓ Prioritize Sleep - Aim for 7–9 hours. Less daylight can naturally make you tired earlier—lean into it.
✓ Keep Moving - Gentle exercise (walking, yoga, Pilates) improves circulation and immune cell activity.
✓ Load Up on Winter Nutrients - Focus on:
- Vitamin D (sunlight + supplements)
- Vitamin C (citrus, peppers, broccoli)
- Zinc (pumpkin seeds, lentils, beans)
- Antioxidants (berries, leafy greens)
✓ Stay Hydrated - Dry winter air makes it easy to become dehydrated, which slows lymphatic flow.
✓ Manage Stress - Holiday overwhelm affects immunity. Try breathwork, mindfulness, or simply creating slower routines.
✓ Get Fresh Air Daily - Even a 10-minute walk outside—especially around the solstice—supports circadian rhythm, hormones, and mood.
As we move through the cold, dark stretch of winter and the busy holiday season, staying on top of your health becomes more important than ever. Prioritize the habits and treatments that keep your body balanced, your mind grounded, and your energy steady.
