Regular salt intake is essential for the human body to function properly. As a guideline, the recommended daily allowance in Germany is 6 grams. If you are experiencing pain, due to strong physical activity or illness, for example, symptoms of deficiency can occur. Signs of sodium deficiency include low blood pressure and muscle spasms. This is especially true at very high temperatures and during high intensity sports. This is because we lose a lot of salt while sweating. The level of salinity in our blood and bodily fluids is 0.9%.
As well as the differences in origin and method of extraction (rock salt, evaporated salt, sea salt), there are differences in the minerals, the purity, the grain and the taste, for example.
Humans need salt for survival. It ensures the transport of water and nutrients in the body and controls the blood pressure. The salt also plays an important role for the nerves; it ensures that stimuli between nerves are passed on correctly.
We experience the way our body deals with the intake of salt and liquids on an everyday basis: If we eat a lot of salt, we are increasingly thirsty. If we drink abundantly, we expel a lot of water as well. If it is hot or if we do sports, we lose water and salts through sweat, which manifests itself in increased levels of thirst. We do not like salty drinks or foods; this shows how the body has a number of mechanisms that regulate its salt intake.
It is almost exactly 0.9% in the blood and bodily fluids. This value must always be kept constant, as many body functions depend on it. The concentration of 0.9% corresponds to the salt concentration in the ancient oceans and was maintained throughout the evolution process from unicellular organisms to humans.
Our bodies self-regulate the salt and water balance. An excessively high or low salt consumption can easily be compensated for in healthy people. This is thanks to the kidneys and the recently discovered salt stores in the deeper layers of the skin.
If you suffer from high blood pressure, it is recommended to reduce your salt intake for a prolonged time. However, this statement has become somewhat controversial in scientific circles, since it is thought that such measures could actually worsen health problems.
It is best to consult with your doctor about salt consumption in relation to elevated blood pressure.
Iodine is a vital trace element and is consumed with food. Our body needs it for the formation of important thyroid hormones and for many metabolic functions.
Fluoride contributes to the maintenance of tooth mineralisation, ensuring that your teeth are protected.
Folic acid is not only important during pregnancy; the B vitamin is needed for cell division and cell regeneration.
Definitely! Gentle peels help the skin to rid its pores of dead cells more quickly. You can make peels yourself using ingredients that are available in most households.
Using salt and olive oil, for example:
Stir some salt with a little olive oil until you get a thick paste that is easy to apply. With coarse salt you get a strong exfoliation, for example, for rougher areas like feet or elbows. When using fine salt, the peeling effect is slightly lessened; the exfoliation is gentler and is perfect for the thighs and upper arms, for example.
Apply the salt-oil mixture to the skin and massage in gently. While the salt mainly takes over the mechanical part, depending on the intensity with which you apply it, the oil soothes the skin. On the feet and on any rougher skin, a little bit of rubbing should be done to stimulate the blood circulation and to remove dead skin cells.
Rinse off any peeling residues with lukewarm water.
If you have chronic cold feet or if you are feeling a little cold, you should try to get warm with salt socks. This old home remedy promotes blood circulation, stimulates the metabolism and warms you up.
And this is how it’s done: Put a pair of clean cotton socks in about a 3 to 5 percent saline solution (30 to 50 grams of salt per litre of water) and let them soak. Remove the socks, wring them out, put them on and put on a pair of woollen socks or wrap a dry towel over the top of them. Put your feet up for about half an hour. As an alternative, the salt socks can be worn overnight in bed.
Important: After removing the salt socks, rinse your feet thoroughly with lukewarm water.
