Caffeine found in coffee and tea, meanwhile, can stimulate the apocrine glands, which are responsible for producing sweat in areas like the armpits and groin. This increased sweat production can create a more favourable environment for bacteria to thrive, potentially leading to stronger body odour, says Beeson. Plus, one study showed that caffeine molecules can be found all the way in sweat too – but there's no data about whether the caffeine itself affects body odour.
