ELI5, Why does it appear we dry off faster after being totally submerged rather than partially wet? I.E. why is air drying off after a shower slower than a bath?

My hotel room has a bathtub/shower in it. Normally when I shower I have to consciously dry off with a towel for a long period, however after taking a bath I was nearly completely dry before the water even drained and I barely had to use a towel! Is there some… weird hydrodynamics at play?

I can think of two things that would affect it:

* Showering will increase the humidity of the air much more than taking a bath will. Humid air is less likely to absorb water, so you will dry slower.

* You will likely be warmer from the bath than from the shower, also speeding up the evaporatio.

Your idea about hydrodynamics is interesting, but I can’t come up with a theory for how that would work.

Your head and your upper body probably don’t spend much time submerged in the bath (not sure of your habits!). If so, you only have half your body to dry, and you don’t have water running all the way down your body.

Your lower body also generally has less tactile sensation (some exclusions apply) so you won’t be as conscious of not feeling dry.

Are you certain that this isn’t just a trick of perception?
