What is the effect of sand baths? To whom is heated sand indicated and contraindicated?

How nice it is on the beach to lie down directly on the hot sea sand! Children, playing, even bury each other on the shoulders or waist-deep, few people know that there is a simple and ancient way of treating heated sand. It is called “psammotherapy” – from the Greek layer psammo – sand and therapia – treatment. Herodotus, Galen, Avicenna wrote about psammotherapy. And in Russia, heated sand began to be used at the end of the 19th century for the treatment of kidney and joint diseases.

For medicinal purposes, sea, lake, river sand is used, which includes quartz, feldspar, mica and other rocks. Depending on the size of the grains of sand, the sand can be coarse-grained (more than 0.5 millimeters each), medium-grained (from 0.5 to 0.25 millimeters) and fine-grained (from 0.25 to 0.1 millimeters).

Protective barriers in the lungs

It is not difficult to imagine what would happen if the smallest particles of dust, aerosols, various microorganisms contained in the inhaled air fall into the lungs. Very soon, their delicate and extremely vulnerable tissue would collapse: after all, the wall thickness of the alveoli – microscopic vesicles – ranges from 0.1 to 4 micrometers. However, thanks to the system of protective mechanisms that stand along the entire path of the air stream from the moment of inhalation up to the alveoli, this does not happen, and the air enters the lungs sufficiently purified from harmful impurities and even warmed up.

The first filter through which the inhaled air passes can be seen with the naked eye, looking at yourself in the mirror: these are the hairs at the beginning of the nasal openings that trap large dust particles suspended in the air. The details of the next filter – the mucous membrane of the nasal cavity – can only be examined with a microscope. By the way, this picture is surprisingly beautiful: Continue reading

Where do the glasses go?

Surprisingly familiar situation. They put the necessary thing somewhere and cannot find it, and then say to yourself: “Sclerosis!” Young people utter this word with coquetry, and annoyance sounds in the elderly person’s voice.

Most people consider this kind of forgetfulness a sign of age-related weakening of memory, although in this case it is just a lack of attention. And since memory is closely connected with intellectual activity, a person of advanced age may experience a pessimistic reassessment of his abilities, which he associates with the onset of old age.

Is it correct? What actually happens to our memory when the age “exceeds” 40, then 50, 60 and beyond? Is memory impairment consistent with age and how is it related to physical and mental health? Can an older person improve memory and how to do it? I will try to answer the questions that concern people who have reached old age. Continue reading
