Your vagina is home to beneficial bacteria that maintain a slightly acidic environment and help protect against infections. It also contains opportunistic microbes that are usually harmless. But when the environment changes — like with excess moisture, heat, or disrupted pH — these microbes can overgrow and cause infections. Maintaining a healthy balance is key to preventing discomfort. Expert insight provided by OB-GYN Prof. Kristina Jariene, MD, PhD, who consulted on this article.
Heat + moisture = a greenhouse for pathogens
Excessive sweating, wet swimsuits, and tight synthetic clothing create a warm, damp environment. These conditions disrupt the vaginal microbiome and allow opportunistic pathogens to grow — such as Candida or bacteria linked to bacterial vaginosis.
Tampons + heat = higher risk of imbalance
In the summer, leaving a tampon in for too long in warm conditions can disrupt the vaginal pH and bacterial balance, potentially leading to infections such as bacterial vaginosis or, in rare cases, toxic shock syndrome. Timely changing and proper hygiene are crucial, particularly in hot weather.
Chlorine can irritate the vaginal lining
Chlorinated pool water can reduce the amount of good bacteria in the vagina. If the microbiome is already unbalanced, this increases the risk of infections.
Synthetic fabrics = more moisture, less airflow
Synthetic fabrics trap heat and moisture, preventing the skin from "breathing”. This creates conditions that encourage the growth of opportunistic microbes and disrupt the vaginal microbiome balance.
Tips for summer
- Change out of a wet swimsuit as soon as possible
- Wear breathable cotton or TENCEL™ underwear
If you choose menstrual products like period panties, be aware many contain synthetic materials. It’s better to choose menstrual underwear that is breathable and free from harmful chemicals, such as GENIAL, which is made without PFAS, ensuring both comfort and a healthier, more sustainable option for your body.
- Change tampons every ~3 hours and after swimming, or use a menstrual cup.
An excellent alternative to tampons could be the GENIAL menstrual cup made of TPE, offering a safe and eco-friendly option for managing your period while reducing the risk of irritation or infection.
- Avoid synthetic liners and opt for breathable alternatives.
GENIAL DAY liners are an excellent choice as they not only allow your skin to breathe but also incorporate a unique FAR-IR Anion Strip that effectively combats bacteria growth and neutralizes unpleasant odors, providing long-lasting comfort and superior hygiene throughout the day.
- Use highly absorbent, breathable pads during your period.
GENIAL DAY pads not only offer superior absorbency and allow your skin to breathe but also feature a FAR-IR Anion Strip that helps reduce bacteria growth and neutralize odors, ensuring long-lasting comfort and hygiene throughout the day.
- Wash with a gentle, fragrance-free intimate cleanser
Take care of your health this summer!
