Is it normal to have sweaty kneecaps?
Yep.Totally normal
Yes, sweaty kneecaps are normal. Your knees can sweat, especially when you’re hot, exercising, or feeling nervous.
Kneecaps have sweat glands too, even if they’re not as famous for sweating as your armpits or palms. Heat, exercise, stress, and snug clothing can all make them damp.
If it happens a lot, that can simply be your body’s normal sweat settings. Annoying, maybe; strange or embarrassing, no.
