Every autumn, as the light gets thin and the mornings turn crisp, my clinic fills up with the same question in a dozen different forms: “Dr. Smith, how do I get through flu season without falling apart?” It’s a fair question. For anyone living with an autoimmune condition, the change of season isn’t just a matter of digging out a warmer coat — it’s a genuine test of resilience.
I’ve been walking this road with patients for thirty years now, since 1996, first as a physician and professor, and also as a patient myself. So let me be clear about something before I share a single tip. What follows are supportive lifestyle habits — the kind of everyday, sensible things that help your body do its own good work. They are not a substitute for medical care, and they are not a substitute for vaccination or any of the conventional prevention your doctor recommends. Think of these tips as the soil, not a replacement for the whole garden. If you’re already doing the standard-of-care things to protect yourself, wonderful. Let’s build on that.
Within The Epigenetic Autoimmune Protocol (the Epi-AIP), immune support isn’t one heroic trick. It’s the quiet cooperation of several pillars working together — Good Food, Supplementation, real rest, and calmer stress physiology. Flu season is simply the time of year when those pillars earn their keep.
Start with the Fifth Pillar: Supplementation
I’m a fan of laying a nutritional foundation before the season gets going, not scrambling once you already feel that first scratch in the throat. For most adults I work with, that foundation looks something like this:
- Vitamin D3 with K2 (around 1,000 IU) — the sunshine you’re not getting in November, with K2 to keep the calcium where it belongs
- Vitamin C (around 1,000 mg)
- An Omega-3 fatty acid (around 1,000 mg) to help steady the body’s inflammatory tone
- Zinc Picolinate (around 50 mg), which I like to take in the morning
- Magnesium Threonate (around 500 mg) in the evening, for the nervous system and for sleep
The reason I keep coming back to these is simple: they help your body make its own antiviral peptides — the small defensive proteins that meet a virus at the door and keep it from settling in deeper. You are not trying to out-muscle a virus. You are trying to be well-supplied enough that your own defences show up on time.
A gentle note on dosing: bodies are not identical, and neither are needs. What suits a healthy adult may be wrong for a child, for someone who is pregnant, or for anyone on medication that interacts with these nutrients. Please treat the numbers above as a starting point for a conversation with your own clinician, not a prescription from a stranger on the internet.
A Warm Remedy from the Old Traditions
When a patient tells me they can feel something coming on — that heavy, achy, “uh-oh” feeling in the first day or two — I often reach for a remedy that predates all of us by a very long time. It comes out of Traditional Chinese Medicine, and I love it because it’s cheap, it’s food, and it’s comforting on a cold evening.
- Slice up the white parts of 3 green onions
- Add one tablespoon of minced and crushed fresh ginger
- Simmer them together for about 10 minutes in 2 cups of water or, better still, bone broth
Sip it warm. Ginger and green onion are warming and gently diaphoretic — they coax a little heat and circulation to the surface, which is exactly what the body seems to want in the earliest, chilliest stage of feeling unwell. And doing it in bone broth means you’re getting easily absorbed minerals and gelatin at the same time. It’s the kind of remedy your great-grandmother might have recognized.
For genuinely high-exposure situations — a long flight, a sick household, a packed clinic waiting room — some people like Oil of Oregano for its antimicrobial character. If you use it, dilute it in a little coconut oil first. Undiluted, it’s fierce stuff on the mouth and gut, and coconut oil makes it far kinder to take.
Eat with the Season (the First Pillar: Good Food)
Winter food should look like winter. This is where the Good Food pillar does its part.
- Bone broth — mineral-rich, gut-soothing, and the base for that ginger-onion remedy above
- Organ meats — nutrient-dense in a way that few modern foods can match
- Fermented vegetables — a little living support for the gut, where so much of your immune system actually lives
Here’s a small principle I find people enjoy: let your cooking time echo the growing time. A quick-growing summer green wants a quick cook. A dense root vegetable that took a whole season to grow rewards a long, slow simmer — that’s what actually unlocks its nutrients and makes them available to you. Winter cooking is slow cooking, and that’s not an accident.
Many patients also find that a gentle approach to intermittent fasting suits the season — giving the digestive system regular rest so metabolic energy can be spent on repair. This is very individual, though. If you are underweight, depleted, managing blood sugar, or in an active flare, fasting may be the wrong tool. Ask before you leap.
Sleep, Mornings, and Stress: Where Immunity Is Actually Built
You cannot supplement your way out of a sleep debt. Flu season is really a sleep-and-stress season wearing a costume.
- Follow the season’s cycle. The nights are long for a reason. Let yourself go to bed earlier than you would in July. Your immune system does much of its finest work while you’re unconscious.
- Wake the body up on purpose. A short morning practice — a cold shower, a few minutes of resistance training, some deliberate breathwork — nudges your nervous system toward resilience and adaptability rather than sluggishness. A little controlled stress in the morning helps your body handle the uncontrolled kind later.
- Turn the stress dial down in the evening. Chronic, humming stress keeps your body in a defensive, alert state, and that state quietly spends the very reserves you need to fight off illness. Real rest — genuine, horizontal, screen-free rest — is not laziness. It’s part of the protocol.
None of this is glamorous. It’s the ordinary stuff, done consistently, that keeps the pillars standing when the wind picks up.
When to Stop Reading and Call Your Doctor
Supportive habits are for the ordinary sniffles and the “I can feel something coming on” moments. They are not for emergencies, and I would be failing you if I didn’t say so plainly.
Please seek medical care promptly for a high fever, difficulty breathing, chest pain, confusion, or symptoms that are getting worse rather than better. And if you or someone you love is in a more vulnerable group — the very young, the elderly, those who are pregnant, or anyone with a serious underlying condition — lower your threshold for reaching out to a professional. There is no prize for toughing it out. Asking for help early is the wise move, not the weak one.
None of what I’ve shared is about blaming you if you get sick. You can do everything “right” and still catch a bug — that’s biology, not a moral failing. The goal is simply to give your body a well-stocked, well-rested foundation, and then to add good medical care on top of it, not instead of it.
Stay warm, sip your broth, sleep like it’s your job, and be kind to yourself this season.
