The holidays are full of joy, celebration, and connection — but for many people, they also come with something far less festive: getting sick. Whether it’s a lingering cold, a sudden fever, or feeling run-down right after travel, it can feel like holiday illness is inevitable. But it isn’t. When you understand why this happens, you can take simple, science-backed steps to support your body — and stay healthy through the most wonderful (and busiest) time of the year.

Here’s what’s really going on behind those holiday sniffles, and how small daily habits — including nutrient-dense support from Vitaminis — can help keep your immune system strong all season long.

1. Stress Levels Peak During the Holidays

The holidays are joyful, yes — but they can also be stressful. Your schedule fills up, routines get disrupted, family dynamics get complicated, and expectations run high.

Biologically, stress reduces the effectiveness of your immune system. When you’re stressed, your body produces more cortisol, which in small doses is fine — but in prolonged doses can suppress immune cell activity and reduce your body’s ability to fight infection.

What to do:

• Protect 10–15 minutes per day for something calming: a walk, journaling, tea, stretching.

• Don’t overschedule — protect buffer time.

• Support your immune system with daily nutrients like Vitamin C, magnesium, and zinc.

Vitaminis Immune Support contains 200% of your daily vitamin C, plus magnesium and zinc — a powerful trifecta known to support a healthy immune response during times of stress.

2. More Socializing = More Germ Exposure

Between holiday parties, family gatherings, work events, travel, concerts, and crowded stores, the holidays dramatically increase how many people you come in contact with.

That means:

• More chances for viral spread

• More time indoors in close quarters

• More exposure to different households’ germs

Even if your immune system is strong, increased exposure raises your chances of catching something.

What to do:

• Wash hands more frequently than usual

• Avoid touching your eyes or face after being in public

• Support your microbiome, which is your first line of defense

Vitaminis Gut Health includes 5 grams of prebiotic fiber plus probiotics equal to 2 cups of yogurt, supporting a healthy gut — and because 70% of your immune system lives in the gut, this is one of the most important ways to strengthen overall immunity.

3. Colder Weather Weakens Your Defenses

Winter brings:

• Lower indoor humidity

• Dry air that dries out your nasal passages

• More time indoors and less fresh air

When your nasal passages dry out, they can’t trap viruses as effectively, making it easier for pathogens to enter your system.

In addition, colder temperatures may impair certain immune responses, giving viruses a better chance to replicate.

What to do:

• Use a humidifier at night

• Stay hydrated

• Get outside for fresh air when possible

• Take warm showers to keep the respiratory tract moist

Hydration is key because your mucous membranes need moisture to do their job. Vitaminis shots — whether Immune Support, Gut Health, or Daily Greens — provide a hydrating burst of liquid with a functional dose of nutrients.

4. Travel Fatigue and Changing Environments

Long flights, different time zones, unfamiliar bedrooms, late nights, and altered routines all take a toll on the body.

Travel affects the immune system by:

• Disrupting sleep (which weakens immunity)

• Increasing exposure to large groups of strangers

• Introducing air that’s extremely dry (especially on planes)

• Exposing you to new strains of viruses

What to do:

• Prioritize sleep before, during, and after travel

• Bring a small immune-support kit (hand sanitizer, tissues, Vitaminis shots)

• Avoid large doses of sugar or alcohol before flying, as they suppress immunity

Many travelers pack Vitaminis Immune Support as an easy, TSA-friendly option to stay on track with immune nutrition even while on the move.

5. Less Sleep and More Late Nights

Sleep is the immune system’s repair cycle. During deep sleep, your body produces cytokines — molecules that help fight infection.

During holiday weeks, sleep often decreases because of:

• Parties

• Shopping

• Cooking

• Travel

• Kids being out of school

• Stress

• Inconsistent bedtime routines

Even a few nights of poor sleep can weaken your ability to fend off a cold or flu.

What to do:

• Set a “wind-down time” at least 30 minutes before bed

• Keep your bedroom cool and dark

• Aim for 7–9 hours whenever possible

• If you’re up late, increase your vitamin intake the next morning

A quick morning Vitaminis Daily Greens shot can help fill nutrient gaps on days when life is chaotic and sleep is short.

6. Holiday Foods Aren’t Always Immune-Friendly

Between desserts, large meals, processed snacks, alcohol, and rich foods, your digestive system often works overtime during the holidays. The problem is that heavily processed foods and sugar can impair immune function, while fiber-rich, nutrient-rich foods support it.

Plus, many people don’t eat enough fruits and vegetables this time of year.

What to do:

• Add veggies to at least one meal a day

• Include fruit as a snack

• Balance indulgent foods with something fresh

• Increase nutrient density with whole-food-based vitamins

Vitaminis Daily Greens, packed with vitamins A, E, D, and folate, helps fill the nutritional gaps that naturally occur during holiday eating patterns.

7. Emotional Ups and Downs Affect Immunity Too

The holiday season can heighten emotions — joy, nostalgia, loneliness, overwhelm, or all of the above.

Emotional turbulence is real and has a direct impact on the immune system. Just like physical stress, emotional stress can weaken the body’s defenses.

What to do:

• Acknowledge your feelings

• Take mental breaks

• Practice mindfulness or gratitude

• Start the morning with a grounding routine

And because emotional stress depletes micronutrients more quickly, getting a daily dose of essential vitamins is especially helpful.

How to Stay Healthy Through the Holidays (the realistic version)

You don’t need perfection — just small, consistent habits:

✔ Get your daily vitamins

Vitaminis shots make this easy:

• Immune Support for vitamin C, magnesium, zinc

• Gut Health for fiber + probiotics

• Daily Greens for vitamins A, D, E, and folate

✔ Prioritize hydration

Even 1–2% dehydration can weaken immunity.

✔ Support your gut

A healthy microbiome is your strongest defense.

✔ Remember sleep is medicine

One good night of sleep can reset a stressed immune system.

✔ Wash your hands

Simple, but still incredibly effective.

✔ Pace yourself

You don’t have to do everything. Choose what matters.

The Bottom Line: Holiday Sickness Isn’t Inevitable

Most people don’t get sick around the holidays because they’re “unlucky” — they get sick because the season creates the perfect storm of stress, exposure, lack of sleep, travel, dry air, and nutrient gaps.

But with small daily steps and thoughtful nourishment — including a consistent routine with Vitaminis — you can support your immune system, protect your energy, and actually enjoy the season feeling your best.

Because your holidays should be full of memories, not medicine cabinets.
