After swimming into the sea, is it better take shower immediately or wait several hours?
I found this on yahoo.anwers:
Best Answer: Salt water can dry up the natural oils in your skin, and this in turn can lead to boils and pimples. When you have been in the sea, you need to wash off the salt as soon as you can, and as you so rightly say, not showering fo a week is gross.
But livestrong says:
The magnesium in seawater may also help hydrate and improve the appearance of your skin. According to a study in the February 2005 edition of the “International Journal of Dermatology,” bathing in a magnesium-rich Dead Sea salt solution helps promote skin moisture. People with atopic dry skin, or dryness on the skin’s surface, submerged one forearm for 15 minutes in a bath solution containing 5 percent Dead Sea salt and the other forearm in regular tap water. Researchers discovered that the salt solution improved skin hydration and significantly reduced skin inflammation symptoms such as redness and roughness when compared to tap water. Observed skin benefits were attributed to the high magnesium content of the Dead Sea salt.
I think that latter is correct, but just need confirmation.
