The point of wearing a swim cap is not to keep your hair dry. It’s to keep your hair out of the way of your face and to make your body more aerodynamic (or, well, hydrodynamic, maybe, in this case). If you don’t want your hair to get wet, then don’t go in the water, or at least not any further than your chest. It’s that simple.
The Woe of the Long Haired Swimmer
If you’ve ever swum with long hair free, you can probably remember why you won’t do it any more. The hair is always in your eyes, your mouth and up your nostrils. This greatly reduces your chances of enjoying the swimming experience. You can’t see, can barely breathe and have to keep clearing the hair away from your face instead of swimming.
Keeping your long hair free for the occasional pool party is one thing, but if you want to swim laps, then long hair is a nuisance. When you swim regularly, you find that any hair winds up being a nuisance, which is why a lot of swimmers have short to no hair.
Wet hair is also heavy hair and any ounce of weight will slow you down, especially when you start to get fatigued. Heavy hair is not only of importance to competitive swimmers, but for people who really enjoy swimming. With heavy, wet hair, you can’t swim as long because you are too tuckered out.
Much Better Than Nothing
Although your hair will still get wet inside of a swim cap, there are still many reasons to wear swim caps when swimming whether you are a guy or a gal (or something in between). Although your hair usually gets a bit damp, it doesn’t become saturated. Your new do won’t be ruined by the pool water and will dry faster.
Also, as pointed out, your hair is out of your face. Being able to easily breathe while swimming can’t be emphasized enough.
Pool filters can get easily clogged with dead strands of hair. The human head sheds dead hair no matter what length it comes in, although long hair tends to clog up the filters faster than short hair. By wearing a cap, you can keep the filter from needing to be cleaned so often.
And swim caps help reduce your drag through the water, making you more dolphin-sleek. This can make you feel more at home in the water and make the act of swimming a lot more fun.
Besides, it’s fun to see other people in swimming caps. Now, we know what we’ll all look like bald. It’s a great equalizer in a public pool, where many people feel self-conscious about being in a revealing swimsuit. In one sense, when you’re feeling a bit insecure about your body, that you see that in some ways we are all alike – we all look goofy in swim caps.
