When I swim, if I just get out of the pool and dry off, it only takes me a minute to fully dry off.
If I take a poolside outdoor shower to get the chlorine off and then dry off, it takes considerably longer to dry off.
This confuses me - getting fully emersed in water should get make me more soaked… but the shower seems to get me more soaked…
I often think about this when taking a shower after swimming… the paradox of water
2 main factors here.
Time between getting out and wrapping yourself in a towel.
How much of your body is actually wetted.
The first means you have time to drop dry, before you grab your towel. It’s only 10s or so, but you can shed a lot of water in that time.
The second matters, since you tend to keep your head out of the water in the pool, but soak it in the shower. Wet hair can hold a lot of water. Even if you don’t dry your hair, the water will run down of the rest of you, as you dry yourself off.
Another point is that the air after a shower is VERY humid, compared to being under the sun after swimming
OP mentions fully submerged so the hair should not matter.
But even then, it’s very likely that your head left the water long before the rest of you.
