temporarily it will be cold and if you have sensitive skin it can itch and turn red since salt makes the temperature go wayyy down, long term is bad because the tmeperatures can get to the negative dgrees, you can definitely get frostbite

"In one of his books Dr. Raju explained about the cells in our body logically and scientifically. He proved how the salty food we eat, spoils the thousands of cells in our body that affects our health, causing many diseases. He proved it with examples in an appealing way.\n\nConsequently I gave up salt three months ago. I have been eating saltless food, drinking 5 liters water per day, eating sprouts as breakfast and drinking a glass of vegetable juice. Ever since I started doing it, I could find good changes in my health.\n\nI am 65 years old. Right from childhood I was allergic to certain things like sour curries, tomato juice, limejuice, soups with onion etc. For that matter cool breeze (even fan breeze) coldwater bath, smoke from the vehicles affected me at once with severe cold and blocked nose. I had a running nose most of the time. If that persisted through out the night in the morning I sneezed heavily and the isnophilia count increased. Every cold season was a nightmare to me. “cold is equal to 10 diseases”, I realized.\n\nOnce I started eating saltless food and drinking 5 liters of water, within 15 days I felt relief from allergic problems. Now, after three months, even if I eat the things that didn’t suit me earlier, I find no problem. Lemon juice, tomato, onions, sour curries etc, how much ever I ate, I feel no allergy for them. Cool breeze, the smoke from the vehicles, head bath daily, none of these are trouble for me now.\n\nFurther, I reduced my weight from 76 kgs to 69 kgs within 15 to 20 days. I am able to go for brisk walking for a hour without any tiresomeness."

Salt lowers the freezing point of water.  That is why the spread salt when it is cold and snow is falling.  The water will stay liquid at lower temperatures.

Salt when dissoved in water dissociates an forms Sodium+ and Chlorine- ions.Sodium in free state immediately reacts with oxygen and burns.That's the reason why sodium is stored under kerosene.When the water containing salt comes in contact with a wound,the Sodium gets deposited on our wounds and starts oxidising and burns our skin which hurts us.

The answer to this problem lies in colligative properties.  The salt ice solution will have a lower freezing point because by adding the salt, the solution is going through freezing point depression, which means that the solute is spreading apart the molecules of the solvent, thus requiring a lower temperature to freeze.

Yes.  Adding salt to frozen water lowers the melting point.  \n\nConsider that snow and ice are really the same thing, in different mass quantities - water in solid state due to ambient temperature.\n\nBest to you.

Salt decrease the melting point of water so adding salt to ice wich is fresh water will make it melt at a lower temperature than 0 celsious.

I haven't found that eating alot of salt creates more sweat but you lose more salt through sweat. Leaving some links for you to read up on the subject...\n\nWhen the water in the sweat evaporates, it leaves the salts (sodium, chloride and potassium) behind on your skin, which is why your skin tastes salty. The loss of excessive amounts of salt and water from your body can quickly dehydrate you, which can lead to circulatory problems, kidney failure and heat stroke.

You can pull ANY muscle.  Try using Aleve or Advil for the pain, an external analgesic such as Icy Hot or Ben Gay would work, and alternate heat and ice.  20 minutes of heat followed by a 20 minute rest then 20 minutes of ice, etc.  Always make sure that neiother the heat or the ice is touching the skin directly as this can cause burns or frostbite.  Be sure to rest the area.  Good luck!!

it's frostbite. the water melting off the ice cube is because salt lowers the freezing point and so the water on your skin is very cold <32 so it freezes the skin. kinda like making ice cream except more painfull

Couple good answers there. The ones about lowering the freezing point are good, but not quite there. If it just lowered the freezing point (which is true) it would never melt the ice/snow, since it nothing has affected the temperature yet. What happens is that the first interaction of salt and ice/snow (water) causes heat to be released, it is an exothermic reaction. That little bit of heat allows more ice to melt, reacting with more salt, creating more heat, melting more ice, etc. So it is the exothermic reaction that causes the melting, the lower freezing point keeps it from refreezing.

When we feel cold or frightened, tiny bumps causing a tingling sensation appear on our skin. Attached to each hair inside the skin is a tiny muscle. When you get scared or feel the cold, messages go shooting off from nerve endings that pick up the cold feeling. In a flash, signals come back to the muscles, and as a result each muscle gets taut. The skin around each hair also gets pulled up. The result is little bumps.

Water IS absorbed through the skin.  Evidence of this is when you get wrinkled skin after taking a long bath or after being in a swimming pool.\n\nThe problem is that water moves slowly into the skin.  In saltwater, the process of osmosis is essentially balanced, which in turn negates water absorbtion.

Balance Your Body Chemistry.\n\nIf you've ever taken chemistry in high school you're familiar with this simple experiment to test the conductivity of salt. Two ends of an electrical wire are attached to a light bulb. The other ends are submerged in a glass of water. Because water alone is not conductive, the bulb does not light up. But when we add a little salt to the water the bulb starts to glow.\n\nIt's the same with our body. When we lack the natural elements in salt we suffer from a chronic energy deficit, or deficit of information. Salt is a core essential nutrient with exceptional abilities and qualities fundamental for keeping us alive.\n\nScience and medicine have tried to define the precise roles of salt in the healthy and diseased human organism. Blood, sweat, and tears all contain salt, and both the skin and the eyes are protected from infectious germs by the anti-bacterial effect of salt. When salt is added to a liquid, particles with opposite charges are formed: a positively charged sodium ion and a negatively charged chloride ion. This is the basis of osmosis which regulates fluid pressure within living cells and protects the body against excessive water loss (as in diarrhoea or on heavy sweating).  Sodium and chloride ions, as well as potassium ions, create a measurable difference in potential across cell membranes. This ensures that the fluid inside living cells remains separate from that outside. Thus, although the human body consists mainly of water, our "inner ocean" does not flow away or evaporate. Sodium ions create a high pressure of liquid in the kidneys and thus regulate their metabolic function. Water is extracted through the renal drainage system. The body thus loses a minimal amount of essential water. Out of 1500 litres of blood which pass daily through the kidneys, only about 1.5 litres of liquid leave the body as urine. \n\nSalt is "fuel" for nerves. Streams of positively and negatively charged ions send impulses to nerve fibres. A muscle cell will only contract if an impulse reaches it. Nerve impulses are partly propelled by co-ordinated changes in charged particles.

Dry ice is frozen carbon dioxide.  The temperature at the surface (where it is sublimating back into gas) is -79 degrees Celsius (about -109 degrees Fahrenheit).\n\nSo yeah, it's really really cold, and if you touch it for too long the tissue damage it creates feels almost exactly like a burn.

By "salt," I'm assuming you are talking about rock salt. It lowers the necessary temperature for which the ice cream will freeze, allowing the ice cream to congeal (come together). This provides the texture that we all have come to know and love. People also use rock salt on snow to melt it. The lowering the freezing point of the water combined with the temperature of the snow remaining the same, causes the snow to melt.

The goosebumps you get on your skin are from special muscles contracting and pulling the skin together. If you notice, it doesn't stay that way forever.  And placing ice on injuries to prevent swelling have nothing to do with reducing the amount of skin you have.\n\nDepending on your age, skin elasticity, and other factors, most likely you need to lose the fat under the skin to make it go away.  You'll have to work out and do cardio for this.\n\nFor others that have lost a significant amount of weight and their skin is unable to return to its former size, the only real answer is cosmetic surgery to remove excess skin.  Once the skin loses its elasticity, you cannot magically get rid of your skin.
