# Recurring Yeast Infections and Summer Training: What Works
A Runner's World contributor discovered practical strategies to prevent recurring yeast infections during summer training while preparing for a half marathon. Working with a women's health physical therapist, the athlete identified specific habits that reduce infection risk in hot, humid conditions.
Yeast thrives in warm, moist environments. Athletes who train heavily in summer face elevated risk because sweat-soaked clothing creates ideal conditions for fungal growth. The physical therapist outlined several evidence-based prevention methods.
Moisture management tops the list. Changing out of wet clothes immediately after workouts prevents prolonged exposure to sweat. This means showering soon after training and switching into dry garments right away. Letting skin air dry completely matters as much as the clothing change itself.
Fabric choice influences risk directly. Moisture-wicking synthetic materials move sweat away from skin faster than cotton, which absorbs and retains moisture. Athletes benefit from switching to performance fabrics for underwear and workout gear.
Hydration and diet play supporting roles. Excessive sugar consumption feeds yeast growth, so reducing refined carbohydrates during peak training season helps. Staying properly hydrated helps regulate body temperature and reduces excessive sweating.
Antifungal powder applied to vulnerable areas before training offers preventive protection. Some athletes use this during their heaviest training blocks as extra insurance.
The physical therapist emphasized that while these habits reduce frequency, they do not guarantee complete prevention. Athletes experiencing persistent infections should consult healthcare providers to rule out underlying conditions.
For endurance athletes training through summer months, the combination of rapid clothing changes, moisture-wicking fabrics, dietary awareness, and prompt hygiene creates the strongest defense against recurrent yeast infections. Starting these habits early in the training season, before hot weather peaks, gives athletes the best chance of staying healthy through race day.
