Can stress affect your vagina?

In short, it’s all about taking care of your genitals in a way that nurtures and encourages a balance of healthy bacteria and its environment. The mix of microbes, genes and environment are known as a microbiome.¹ We’ve all heard of ‘good bacteria’ to support other areas of the body – and intimate areas are no different. The species of bacteria most commonly found in a healthy vulva’s microenvironment is Lactobacillus – a crucial part to the vagina’s defence system.² 

However, there are so many other factors that contribute to your vaginal balance, and like a fingerprint, everyone has a unique microbiome.3 Especially with so many hormonal, hereditary, and lifestyle influences, such as the menstrual cycle, contraceptives, pregnancy, diet, ethnicity, and stress.¹ 

As individual as your eye colour, every vagina responds differently to these external factors, from particular period products irritating your labia (the folds that surround the opening of the vagina) to certain foods triggering an imbalance in your pH (naturally between 3.8 and 5). Stress might be just another of these factors to keep in mind when your vagina isn’t quite feeling its best.

As Lactobacillus helps to protect against germs, your vagina might be sensitive to infections such as bacterial vaginosis (BV), thrush, and sexually transmitted infections (STIs). Much of the research in this area has been done on animals, so more human studies are needed to explore the role of stress in affecting vaginal health. However, although we might not understand how this happens, many experts believe stress does impact vaginal health. 

Stress can cause vaginal dryness too. In fact, 17% of women aged 18-50 experience it. Dryness is sometimes down to a psychological reaction, as your body can go into ‘fight or flight’ mode. This mental distraction and increased blood pressure can hinder your arousal during intimacy. Certain soaps, washing powders, and even certain medications can also dry out the vagina’s natural moisture.⁶

Antibiotics can also cause disruption in your vaginal health. If you’ve been prescribed them, you should absolutely take your doctor’s advice and finish the course. However, there’s evidence that regular antibiotic use can create an imbalance in your body’s ‘good bacteria’ reserves. Probiotics such as D-lactic acid, glycogen, and oligosaccharide may stimulate bacterial growth and help restore the balance.⁷

So, when you’ve finished your medication, taking prebiotic supplements or eating probiotic foods might be a good route to consider, although evidence for probiotics is still growing, some studies have shown promising results. Please speak to your doctor before taking probiotics, especially if you have a weakened immune system or pre-existing conditions.⁸ 

If you notice dryness regularly, you might want to chat to your GP to help get to the root cause. If you’re just looking for occasional support with lubrication, there are water-based lubricants which can help.
