My 7-Step Winter Longevity Checklist: Reduce Inflammation, Support Your Immune System, and Protect Your Mood

November 15, 2026

Every year around this time, I see the same pattern in my patients. More colds. Lower moods. Stiffer joints. And a slow slide away from the habits that kept them feeling great all summer.

What gives?

Well, it’s not just one thing.

Shorter days, colder weather, less light, fall viruses, end-of-year stress, and holiday desserts tend to tilt our bodies toward inflammation and infection—and often have us collapsing on the couch with comfort food rather than prioritizing veggies and gym time.

So even though it can be tempting to treat winter as something to survive, I treat it as an opportunity to double down on the foundations.

Think of it like a training block for your longevity.

Here’s the exact winter checklist I follow to keep myself as healthy and strong as possible: 7 habits that you can now use to protect your sleep, immune system, metabolism, and mood until spring.

#1. Anchor Your Body Clock

Your circadian rhythm runs nearly every system in your body, including immune repair, which happens largely while you sleep. Winter’s late sunrises, plus erratic eating schedules and long evenings spent on screens under artificial lights, can throw that rhythm off.

▶ What I do:

• Keep the same sleep window seven days a week, weekends included.
• Get outside for 10–15 minutes of morning light within an hour of waking. A cloudy sky still delivers far more light than your kitchen.
• Keep my bedroom as dark as possible with blackout shades. A sleep mask can also work surprisingly well and is one of the easiest hacks out there. (I personally use BON CHARGE’s Classic Blackout Mask.)

#2. Eat Protein-Forward, Anti-Inflammatory Meals

Winter cravings pull toward bread, pasta, and sweets. Instead, focus on building meals that help keep blood sugar steady, bring inflammation down, and build muscle up.

▶ What I do:

• Build every meal around a high-quality source of protein, then fill half my plate with non-starchy vegetables. (My 10-Day Detox offers a powerful anti-inflammatory plan that can support you here.)
• Cook with ginger, garlic, turmeric, and other herbs, which are anti-inflammatory powerhouses. Soups, stews, and curries make this easy in cold weather. (You can try my Sesame Ginger Tofu or Cardamom Beet & Beef Stew if you need some inspiration.)
• Eat fermented foods daily, like sauerkraut, kimchi, or unsweetened yogurt or kefir. These help feed the gut, where much of your immune system lives.
• Have wild salmon or sardines a few times a week for omega-3s.

#3. Be Intentional with Seasonal Eating

Between Thanksgiving and New Year’s, there’s often more alcohol, more sugar, heavier meals, and late-night eating. Alcohol disrupts sleep, excess sugar can contribute to inflammation, and eating too close to bedtime can interfere with rest and recovery.

Of course, I want you to enjoy the holidays. Food is part of how we celebrate and connect. The key is to make indulgences intentional, rather than letting them become your default for the entire season.

▶ What I do:

• Keep alcohol to an occasional glass, not a nightly habit.
• Avoid sugary desserts. They’re generally not worth it to me—but find what works for you.
• Close the kitchen early. I aim to finish dinner 3–4 hours before bed.

#4. Train for Muscle and Metabolism

Muscle is your body’s biggest glucose sink and one of the strongest predictors of healthy aging. Winter is when most people lose it.

▶ What I do:

• Strength train two to three times a week. This is a non-negotiable for me.
• Add zone-2 cardio on most other days. I particularly love biking, hiking, and playing tennis. To hit zone-2, aim for a pace where you can talk, but you can’t necessarily sing. Shoot for 150 minutes per week.
• Take a 10–15 minute walk after meals. Even a short walk measurably blunts the blood sugar spike that follows eating.

#5. Use Heat and Cold on Purpose

Thanks to a biological process called hormesis, brief, controlled stress makes your body more resilient. Heat and cold are two of the easiest ways to get it.

▶ What I do:

• Use the sauna a few days a week, staying long enough to feel somewhat uncomfortable, usually 5–20 minutes. A hot bath works too. (My Sunlighten sauna is a core part of my health and longevity routine.)
• Save cold exposure for earlier in the day. A cold shower or plunge lifts mood and alertness, which is what you want in the morning, not at bedtime. Start with 30–60 seconds and build to two or three minutes.

(If you have a heart condition or are pregnant, check with your doctor first.)

#6. Test, Don’t Guess: Vitamin D, Magnesium, and Omega-3s

In much of the country, winter sunlight is too weak for your skin to make meaningful vitamin D, which supports immune function, mood, and bone health. Omega-3 fatty acids help regulate inflammation and support brain and cardiovascular health, while magnesium is involved in hundreds of essential processes, including blood sugar regulation, muscle function, and sleep.

Getting enough of these nutrients year-round matters, but winter is a good opportunity to assess where you stand and address any gaps.

▶ What I do:

• Check my vitamin D and keep it in the range I consider optimal: 50–80 ng/mL. This may warrant supplementation, depending on results.
• Check my Omega-3 Index through Function Health and aim for 8% or higher. This can be shifted with both omega-3-rich foods (e.g., salmon, herring, chia seeds, flaxseeds) and a supplement if needed.
• Keep my magnesium topped up through food (e.g., leafy greens, pumpkin seeds, almonds) and a supplement if needed. It supports sleep, stress, and blood sugar.

#7. Have a Plan for Sick Season

The goal isn’t to never get sick (that’s generally not realistic). It’s to give your immune system the support it needs to fight infections and recover well when illness strikes.

▶ What I do:

• Stick to a simple hygiene routine. I wash my hands when I get home and before eating, and keep my hands away from my face.
• Prioritize rest at the first hint of symptoms. Sleep is one of the most important tools for supporting immune function.
• Eat lots of fresh, colorful produce, which is full of phytonutrients that support immune health. I also add mushrooms like shiitake and maitake, which contain beta-glucans, natural compounds that help regulate immune activity.
• Supplement for immune support, as needed. Check out The Best Supplements to Strengthen Your Immune System for more information.

Make Winter Work for You

Winter doesn’t need to be a season of setbacks. With the right approach, you can go into spring stronger, sharper, and more resilient than you were in the fall.

To get started, pick the two strategies that would make the biggest difference for you this winter and begin practicing them consistently. After a couple of weeks, add another one. Keep building as it feels good for you.
