SALT WATER

  This might be a dumb question,but does any1 know if being in sea water for long periods is harmful to your body.Like some of you know im new to this sport and im in the water on average 6 to 7 hours per weekend then about 3 hours during the week.Once i get my wet suit ill probably be in there much much longer.Salt water is corrosive to everything right,so could it be bad for us in any way.

  "seriously???"
  dont worry about it bro..... if anything its the sun that does the damage, so bath yourself in sunscreen if your worried about your skin> >>> (use any of the Footit brothers for an example, those kids were born in salt water and theyve turned out just fine.

  Yeah dude, like the man said, it's not going to worry you, if you ever cut yourself on rocks or have worsening fin-cuts or something and you don't treat it the salt water can give you sea ulcers if you surf for long enough but as long as you have no open wounds you're all good all the time...

  The reversible dependence of skin osmotic water permeability (L PD ) upon the ionic concentration of the outer bathing solution — which we have called ldquohydrosmotic salt effectrdquo (HSE) — was studied in the isolated skin of the toadBufo marinus ictericus. The skin osmotic water flow (J V ) was measured as a function of outer bathing solution osmolality (O e ).L PD , calculated as (J v /Deltapgr) tauP=0 (where Deltapgr and DeltaP are the osmotic and hydrostatic pressure differences across the skin, respectively) was constant whenO e was altered with sucrose, a nonelectrolyte. In contrast,L PD increased continuously in the hypotonic range asO e was raised from zero (distilled water) with NaCl or KCl. The HSE could also be evoked in the condition of reversed osmotic volume flow, with the outer bathing medium made hypertonic with sucrose.
  Diffusional14C-sucrose permeability, measured in theJ v =0 condition to prevent solvent drag of sucrose in the paracellular pathways, indicate that the hydrosmotic salt effect cannot be explained by assuming a paracellular permeability increase, due to tight junction opening, but might be interpreted as due to changes in the osmotic water permeability of the apical membranes of the most superficial cells of the epithelium.
  The hydrosmotic salt effect can be elicited in control skins and in vasopressin-stimulated skins, on top of the hormonal response.
  The time course of the hydrosmotic salt effect is substantially different from that of the hydrosmotic response to vasopressin. Its half-time is 4 to 5 times faster than that of vasopressin action, with individual values as short as 1.5 min.
  The time courses of the hydrosmotic salt-effect onset and reversibility are exponential, clearly contrasting with the typical sigmoidal shape of vasopressin onset and washout time courses.
  Based on time course data and on speed of response we postulate that the mechanism underlying the hydrosmotic salt effect is due to modifications of existing water pathways in the apical membrane, rather than to incorporation and removal of water permeability units in this structure.

  After much hypothesising and philosophysing that actually makes a lot of sense....NOOOOT!!!!????
