# Yeast Infections and How to Prevent Them in Everyday Life Yeast infections are a common health is
Yeast infections are among those unpleasant health problems that rarely get talked about, even though the vast majority of women will encounter them at some point in their lives – as will a significant percentage of men. They are caused by the overgrowth of the yeast Candida albicans, which is a natural part of the human body's microflora but can spiral out of control under certain conditions. And those conditions are the key to the whole issue: yeast infections are far from being related only to hygiene or chance – their triggers are hidden in everyday habits, from what we eat, to what we wear, to the way we care for our bodies.
The World Health Organization and numerous dermatologists point out that candidiasis – the medical term for a yeast infection – is strongly influenced by lifestyle. This may seem alarming at first glance, but it is actually liberating: if infection is largely caused by the way we live, then it can be prevented in the same way.

What's on our plate and why it matters
Few people eating a breakfast of white bread rolls and jam realize that this very meal may be contributing to the development of a yeast infection. Yeasts feed on sugars – and that is meant quite literally. Refined sugars, white flour, sweet drinks and alcohol create an environment in the gut that directly promotes the overgrowth of Candida. The intestinal microbiome plays a crucial role in whether the body can keep yeast in check, and a diet rich in simple carbohydrates disrupts this balance.
Research published in the journal Nutrients suggests that chronic consumption of sugar and processed foods is one of the main factors contributing to recurrent yeast infections. This is not limited to vaginal candidiasis – the same mechanism underlies yeast infections of the skin, oral cavity and intestines.
On the other hand, there are foods that act as natural allies. Fermented foods such as natural yogurt, kefir, kimchi or sauerkraut supply the body with beneficial bacteria – probiotics – that naturally compete with Candida for space and nutrients. Garlic contains allicin, a substance with proven antifungal properties, and coconut oil is rich in caprylic acid, which can disrupt the cell membranes of yeast. Including these foods in one's diet is no miracle cure, but as part of an overall preventive approach, they make good sense.
A telling real-life example: a woman who repeatedly struggled with vaginal yeast infections and found no lasting relief even after repeated treatment eventually discovered – following a consultation with a nutrition specialist – that her problem was a daily glass of fruit juice and a bowl of sugary cereal for breakfast. After switching to a lower-sugar diet and regularly incorporating probiotics, the infections stopped recurring. This is not an exceptional story – similar experiences fill online forums and gynaecologists' offices alike.
What we drink is just as important as what we eat. Dehydration weakens mucous membranes and thereby reduces their natural defences, while adequate intake of plain water helps maintain healthy pH levels in the intimate area and the gut. Alcohol, especially sweet wines and beers, also directly contributes to Candida overgrowth – not only because of its sugar content, but also because it disrupts the gut microbiome and weakens the immune system.
Clothing as a trigger nobody talks about
If we asked the average person what clothing has to do with yeast infections, they would probably shrug. Yet it is one of the most underestimated factors, playing a surprisingly significant role. Yeasts love warmth, moisture and lack of airflow – and these are precisely the conditions created by a whole range of fashion choices we consider perfectly normal.
Synthetic materials such as polyester, nylon or elastane wick away moisture very poorly. Wearing such underwear or clothing causes sweat and natural moisture to accumulate in the intimate area and in skin folds, creating an ideal environment for Candida to multiply. Tight jeans, leggings or shaping underwear amplify this effect further – they restrict air circulation and raise the temperature in the areas of the body they cling to.
Dermatologists and gynaecologists agree: cotton underwear is unquestionably the preferred choice for preventing yeast infections. Cotton is breathable, absorbs moisture well and does not retain heat. Natural materials such as linen or bamboo work similarly and also have inherent antibacterial properties. In the context of sustainable fashion, this is doubly good news: natural materials are healthier not only for the planet, but for our bodies as well.
As dermatologist and healthy lifestyle advocate Joshua Zeichner puts it: "The skin is the body's largest organ, and what we dress it in directly affects its microbiome and overall health." This idea applies doubly to areas where skin comes into contact with moisture and heat.
Post-exercise situations also deserve attention. Damp sportswear – whether after a workout or after swimming – should not be worn any longer than necessary. Changing into dry, breathable clothing as soon as possible after physical activity is a simple but effective step. Similarly, it is advisable to avoid sitting in a wet swimsuit for extended periods, as this too creates conditions favourable to the development of a yeast infection.
The choice of clothing thus becomes part of a conscious approach to health – and in this sense, the topic of yeast infections naturally connects with the broader philosophy of a sustainable and healthy lifestyle that prioritises quality and naturalness over fast fashion and synthetic materials.
Hygiene: less can be more
Perhaps the most widespread myth associated with yeast infections is the belief that they result from insufficient cleanliness. The opposite is true. Excessive or inappropriate hygiene is paradoxically one of the main triggers of yeast infections, particularly in the intimate area.
The vagina is a self-regulating organ with a naturally acidic pH ranging between 3.8 and 4.5, which protects against the overgrowth of harmful microorganisms, including Candida. Using harsh soaps, scented intimate shower gels, intimate deodorants or douches disrupts this natural pH and destroys the beneficial bacteria – particularly lactobacilli – that form the body's natural defence. The result is an environment in which yeast can proliferate unchecked.
Experts from the American College of Obstetricians and Gynecologists have long recommended washing intimate areas with warm water only, or at most with a gentle, fragrance-free soap that does not disturb the natural pH. Internal douching is considered medically inadvisable, and its regular use is associated not only with yeast infections but also with bacterial vaginosis and an increased risk of sexually transmitted infections.
Hygiene habits when using toilet paper or menstrual products are equally important. Scented toilet paper, sanitary pads with plastic surfaces or scented tampons can irritate mucous membranes and disrupt the natural microflora. Switching to unscented or organic cotton alternatives – or to a menstrual cup or reusable cloth pads – is a step that many women describe as significantly beneficial for the overall health of the intimate area.
The use of antibiotics also deserves attention. Antibiotics are essential in treating bacterial infections, but their side effect is the disruption of both intestinal and vaginal microflora – they kill not only harmful bacteria but beneficial ones as well. This is why so many women suffer from yeast infections following a course of antibiotics. In such cases, preventive use of probiotics – ideally containing Lactobacillus rhamnosus or Lactobacillus reuteri – can be an effective strategy for supporting the microflora. This approach is supported by research published in the journal FEMS Immunology & Medical Microbiology.
Care of the hands and nails is also an integral part of hygiene habits, particularly when there is a risk of transferring yeast from other parts of the body or from the surrounding environment. Regular handwashing and keeping nails trimmed reduce the risk of mechanically introducing Candida into the intimate area.
The overall picture that emerges from these findings is surprisingly consistent: yeast infections are not random, but are closely linked to everyday decisions about what we eat, what we wear and how we care for our bodies. This does not mean that changing one thing will make the problem disappear – the body is a complex system and yeast infections can have multiple triggers at once. But precisely because these triggers are so specific and manageable, prevention is within each of our own hands.
Conscious selection of probiotic-rich foods, a preference for natural and breathable materials in clothing, and gentle hygiene free of harsh chemicals – these are the three pillars on which the body's natural resilience against Candida overgrowth rests. And none of this requires radical change, but rather gradual, sustainable steps that fit naturally into a broader approach to a healthy and mindful lifestyle. Perhaps it is time to stop viewing yeast infections as an unpleasant coincidence and start seeing them as a message from the body – a message that is worth listening to.
