The short explanation
A smell that builds up through the day when you sit for long hours is often from sweat on the skin of the groin and vulva rather than from the vagina itself. The groin has many sweat glands, and warmth, tight clothes and synthetic fabrics let sweat and skin bacteria build up and produce odour. Other people usually notice it much less than you do. Breathable cotton underwear, looser trousers, getting up to move during the day, washing the outer area with plain water or mild unscented soap, and drying well usually help. A vaginal smell that is fishy, strong, or comes with unusual discharge is different and worth checking.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Panty liners worn all day can trap heat and moisture; if you use them, change them often or try going without.
- A rash in the skin folds with itching, especially in humid weather, may be a fungal infection of the skin.
- Avoid deodorants and perfumed sprays on the vulva, as they can irritate the skin.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This cannot tell you whether the smell is from sweat or from a vaginal infection. If you are unsure, a clinician can check quickly.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Does this sound like a sweat smell or a vaginal infection?
- Is there a skin rash in the groin that needs treatment?
- What daily habits do you suggest for long working hours?
When to seek help
Clinician-approved guidance for this topic. When in doubt, being seen is never the wrong choice.
Book an appointment soon
- See a clinician within a few days if there is a fishy or strong vaginal smell, unusual discharge, itching or a rash.
Raise it at a routine appointment
- Bring it up at a routine visit if you would like reassurance. You can ask for a woman doctor, and you can bring a friend or relative into the room with you if that helps.
