Why Candida Overgrowth Gets Worse in Colder Months (And What to Do About It)
If colder months always seem to knock you off your game, you’re not alone. As the days get shorter and the temperatures drop, millions of people feel their energy dip and their cravings take over.
In fact, two in five Americans say they feel worse this time of year, often describing lower energy, stronger cravings, and worse mental health. According to the American Psychiatric Association, 41% report a drop in mood, and 21% admit to eating more sweets to cope (American Psychiatric Association, 2024).
Some of that dip comes down to lifestyle and reduced sunlight, which can affect sleep, hormones, and mood. But there’s another reason some people feel off in the colder months: Candida.
What Exactly Is Candida?
Candida is a type of yeast that naturally lives in your body, primarily in the gut, mouth, and mucous membranes. In balance, it’s harmless. But when it multiplies out of control, it can disrupt digestion, suppress immunity, and trigger everything from stubborn fatigue to recurring infections.
Several factors can throw off that balance: antibiotics, high-sugar diets, stress, and a weakened immune system.
But seasonal changes also play a surprisingly big role, especially in the fall or winter.
How Seasons Affect Candida Growth
A 2025 study published in Antibiotics (Basel) by researchers at the University of Palermo found that the distribution of Candida species changes throughout the year, with different strains showing increased activity in colder or more humid seasons.
Environmental conditions alter how Candida forms biofilms, which are sticky layers that make it harder to eliminate, and these biofilms respond directly to changes in temperature and moisture levels (Di Carlo et al., 2025, PMID: 40426519).
In simple terms: when the environment changes, your inner ecosystem does too.
Fall and winter often bring:
- Dry indoor air and lower sunlight, which reduce vitamin D and weaken immune defenses.
- Heavier foods and more sugar, which feed yeast and slow digestion.
-
And less movement and sweating, which slows detoxification.
All of these make it easier for Candida to multiply, and make it harder for your body to keep it in check.
So, if you suspect that you may have Candida overgrowth, here’s what can do to help keep it in check.
1. Rebalance what’s on your plate
When the temperature drops, comfort foods take center stage: think breads, pastas, and sweet treats. But these are also Candida’s favorite foods. Too much sugar or refined carbohydrate gives yeast the fuel it needs to grow.
Instead, focus on warming, savory meals that don’t spike your blood sugar, like the ones we recommend for the Body Ecology Diet.
Some of the best anti-candida foods you can eat during this time of year are:
- Non-starchy vegetables like kale, cabbage, broccoli, cauliflower, celery, zucchini, and radishes
- Clean proteins such as wild-caught fish, pasture-raised eggs, turkey, chicken, and grass-fed beef
- Healthy fats, including coconut oil, ghee, olive oil, and avocado
- Fermented foods like InnergyBiotic, cultured vegetables, and young coconut kefir to repopulate your gut with good bacteria
-
Herbs and spices such as garlic, oregano, ginger, cinnamon, and turmeric for their natural antifungal properties
These foods work together to help stabilize blood sugar, support digestion, and create an internal environment where Candida can’t thrive.
2. Support your immune system naturally
Your immune system is your first line of defense against any kind of overgrowth, including Candida. And during winter, it naturally has to work harder since less sunlight means less vitamin D, which can weaken immune resilience.
One way to strengthen your immune system is by adding foods and nutrients that have natural antimicrobial and anti-inflammatory effects. Black cumin seed oil (Nigella sativa) is one of the best. It’s been used for centuries in traditional medicine to support immune health, and modern studies show that its active compound, thymoquinone, helps the body defend against harmful microbes while maintaining healthy inflammatory balance.
You can find black cumin seed oil in capsule form or liquid form, or sprinkle whole seeds onto soups and stews for a warm, peppery flavor.
Combine that with probiotic-rich fermented foods, lots of water, and plenty of rest, and you’ll give your immune system the steady support it needs to stay balanced all winter long.
3. Keep detox pathways open
When your body slows down in winter, so does elimination. Sweating less, moving less, and drinking less water can all make it harder for your system to flush out waste. But, as Candida dies off, those toxins can build up and worsen symptoms.
That’s why this time of year, light movement can make a big difference. Gentle yoga, stretching, tai chi, or even a short walk increase circulation and lymphatic flow, which helps your body move toxins out more efficiently. Breathwork can also help by stimulating the parasympathetic nervous system and supporting oxygen exchange, which aids in natural detoxification.
Hydration matters too. Warm water with lemon or herbal teas like ginger or dandelion root can support liver function and digestion. And eating fiber-rich, water-dense vegetables helps bind and carry waste through the digestive tract.
These small daily habits keep your internal pathways clear, helping your body eliminate toxins and maintain balance — especially when you’re rebalancing your gut after Candida overgrowth.
