As summer approaches, health experts are alerting the public to an expected surge in thrush cases, a common fungal infection affecting approximately 75% of women in the UK at least once in their lifetime. Thrush, caused by an overgrowth of the yeast Candida, thrives in warm, moist environments—conditions that become more prevalent during the hotter months.
Amie Anand, a pharmacist at Well Pharmacy Online Doctor, explains, “Thrush flourishes in warm, damp areas and often results when the natural balance of bacteria and yeast in the vagina is disrupted. Increased sweating, frequent swimming, and higher temperatures during summer—especially when traveling—can upset this balance.”
To reduce the risk, Amie advises wearing breathable, loose-fitting clothing, choosing cotton underwear, and avoiding remaining in wet swimwear for extended periods.

Key factors leading to a rise in thrush during summer include:
-
Increased Heat and Sweat: Elevated temperatures cause more sweating in areas like the vagina, underarms, and beneath the breasts, creating ideal conditions for yeast growth. Opting for loose, breathable fabrics such as cotton helps minimize moisture buildup.
-
Wet Swimwear and Clothing: Prolonged exposure to damp swimwear or sweaty exercise clothes traps moisture against the skin, disrupting natural bacterial balance and encouraging Candida growth. Changing into dry clothes promptly after swimming or working out is essential.
-
Tight and Synthetic Clothing: Wearing tight garments made from synthetic materials like polyester and nylon limits airflow and traps heat and moisture. Choosing looser, natural-fiber clothing can significantly lower the risk.
-
Hormonal Fluctuations: Changes in hormone levels due to the menstrual cycle or birth control pills can alter vaginal pH, making the area more vulnerable to thrush.
-
Diet and Sugar Intake: Summer events often include sugary treats and drinks, which can fuel yeast growth. Reducing sugar consumption and incorporating probiotic-rich foods like yoghurt and kefir supports a healthier vaginal environment.
-
Travel and Hygiene Disruptions: Being away from home can interfere with regular hygiene habits, exposing the skin to sweat longer and different products that may disturb pH levels. Packing breathable underwear and maintaining good hygiene routines while traveling is recommended.
Recognizing early symptoms—such as itching, irritation, burning sensations, thick white discharge, and redness—allows prompt treatment, helping prevent the infection from worsening.
Amie concludes, “If untreated, thrush can cause significant discomfort. Taking preventive measures during summer and seeking treatment at the first signs will help keep the infection at bay.”
