How come when you've recently gone swimming you can still feel the waves at your arms and legs?

your nerves kinda get used to the feeling and keep on sending the same inpulses to the brain even a long time after you're out of the water

You may have been chilly.\nOr, after being in the water where your limbs were floating & supported by the water, they may have temporarily grown acclimated to being held up. So, when you got out of the tub, they suddenly had to support your frame again, & they were trembling as they adjusted back to this.

Basically your body becomes very warm, which causes vasodilation of  your blood vessels. Meaning your blood vessels "expand" thus there is less flow to your brain, hence your lightheadedness. If you sit in a really hot tub for 30min and then quickly stand up and jump around,  you might even pass out.

Now for the correct answer. It is due to the process of osmosis. The water outside your body has a higher concentration of dissolved solutes then the inside of your body. This means there is a higher concentration of water in your body than outside your body. Osmosis will cause water to move through a semi-permeable membrane from inside your body to the water outside. Thus there is a net water loss and your skins wrinkles.

Well, the temperature doesn't matter. What does matter is the concentration of the water outside of you. It's osmosis/diffusion. You have water in your body and there's water outside of you; but the water outside gonna have a higher concentration that the water inside of you. This is when you take into consideration that the water outside of you  will include dirt(some salts) and other chemicals like from your soap or shampoo, which is why it's concentration is higher. The whole process of your fingers shriveling-up is because the water inside of you leaves your body in attempt to balance the concentration outside to equal yours.

because the sound reverberates in your skull, and with the water acting as a sound proofing, there is very little distraction noise-wise and the whispering becomes clear.  Basically you are hearing from the inside out.  Now when you come out of the water, there is water in your ears, and you no longer have the insulation of the water around your head.  That, combined with the noise of sitting up, the water splashing around you, the ambient noise from your surroundings, causes you to not recieve the soundwaves, which are now outside of your head and "mixing" with the rest of the noise.\n\nGet it?

I was about 10 years old. and we all go swimming at the beach.  The beach was noisy; loud with color and swarming people.  Im deaf, but even I ehard the noise pervading the air. The low rumble of voices, the riot of color and teeming flesh...very aggravating.  \n\nThe sand was hot, but the waters of the Pacific were chill.  What a delightful feel!  I leapt into the waves and swam out.  Once beyond the breakers, I turned and rested my back upon the waters, floating arms spread out and eyes closed.  I breathed deeply, smelling the salt on the breeze.  I could feel the warm sun upon my skin and the cool waters on my back.  I was being rocked by the waves, a gentle bobbing, up and down, up and down....There was no noise, no riot of color, no chaos of teeming flesh invading my space.  just me, the sun, the wind, and the sea. \n\nI floated on those waters for a full 15 minutee, just enjoying the sensual experience of hot, cool, and wet. That was all i was concious of, what I was sensing.  I ahd no thoughts, no worries, not obligations.  I may have dozed off too, I cant remember...but eventually I swam back to shore feeling the most calm and refreshed I have ever felt in my life, before and since.\n\nI have never had a moment like that since, and I doubt I ever will again.  and thats okay.  The peace i gained that day is forever contained in that memory and will be with me so long as that memory lives still in my mind.  Even recalling it brings me back to that peaceful joy.

If you stay in the water TOO LONG then your skin is obviously going to because you've deepend the D.N.A lines\nToo much science stuff to understand? Ask your local neighbour!

Don't worry it happens to me too, all the time!\n\nNerves Know\nShivers are reflexes (say: ree-fleks-iz), which are things your body does automatically to keep you safe and healthy. Reflexes are controlled by your nervous system, which is made up of your brain, your spinal cord, and lots and lots of little nerves that stretch out all over your body. Nerves are like little strings or wires that carry information.\n\nWhat kind of information? Well, your nerves sense that the cool water of the lake has lowered your body temperature. Your body needs to stay at a toasty 98.6 degrees Fahrenheit (37 degrees Celsius) for you to be safe and comfortable. The nerves send signals saying, "I'm cold! Warm me up!"\n\nMuscles in Action\nThat's when things really start to get interesting. The signals go to your brain (telling you to wrap in the towel) and to your spinal cord, which sends a message to other nerves all over your body. What happens next? Your muscles tighten and loosen really fast. Why? They're trying to warm you up, just like taking a jog around the lake would do. Once you get all snug and cozy in your towel and your body warms back up, your brain and nerves tell your muscles to stop shivering.\n\nThere are other times when you might shiver, too. Sometimes you'll shiver when you're excited or afraid. When you feel these things, your brain and nerves send out messages through your body that cause your muscles to get excited, so you shiver.

This is weird. I can swim great but when i was 12 (i'm now 18), i was in a pool and my friends brother jumped on top of me and started choking me underwater. I guess mine would have to be drowing.

When you are cold, your blood goes to your body's core, away from the extremities.  Once you hit a warm shower, your body dumps blood back to your extremities when they're still cold.  This causes a drop in your body's core temperature, causing you to shiver.  This is experienced by Arctic/antarctic swimmers.  Once they get out of the water and into a warm bath or shower, their core temperature drops because their blood is running through relatively cool arms & legs.

There's nowhere else for them to go. Like, if you splash your hand in a bath, the disturbance in the water must spread until it hits the side. If you dive into a pool, the wave will reach the side of the pool.\nAlso, the wave height gets magnified when the water becomes shallower, as it usually does near the shore of a lake or sea. So if you look over a cliff into deep water, even if it's rough the waves are not so big as they hit the base of the cliff, but if there's a beach with shallow water just around the headland the waves there will be large breakers.

what is incredible about swimming is that it is horizontal exercise,and like flying in mid-air! For some people it might be the only horizontal exercise they ever get.. Because you are in the water you are able to move more weight with less resistance,and exercise your cardio-vascular system ( if you progress into laps,especially) A great body workout!!

in a calm sea, it should be easier to swim since the water density is higher allowing you to float easily.\nbut then depending on factors like waves and river speeds, your experience could vary!

Its because of static electric charge. This happens more when a person is on plastic chair or floor and because of some friction ones body is charged with static electric. If some other person shake hands he will feel electrical current moving through the body.

it may be circulation.\n\nmake sure you stretch before AND after you work out,\n\nalso, the constant motion or vibration can numb nerves, as long as feeling comes back within a few minutes, its no big deal.
