are the hot bath & shower and soap.
The skin is the core of our health and energy. Taking the hot bath & shower carries away the vital part of the surface blood vessel structure - sea (natural) salt..
Soap effectively removes the main body defense - the natural skin protective oil. No any other oil is able to replace it.
Many health problems this day - back , joints, allergies, legs weakness, premature aging, cancer are some of them - come from the loss of skin salt or the skin protective oil or both.
Especially this is bad for new born children.
To do all this harm , the huge amounts of precious water and energy are wasting..
Daily recharge the skin after removing the old one ( stoning ), with natural (sea) salt/. Use the soaked with the sea salt cold water solution rubber sponge all over the body before the quick cold shower..
