Annual vacation, travel and change of environment according to the age of the person
Each person usually plans a vacation or trip according to their economic abilities and their own life situation. However, the customary holiday season most often occurs during the summer period. The need for a change of environment, for a stay in fresh and clean air (without daily obligations and worries and an established, often monotonous way of life) is becoming more and more imperative for people of all age groups. For many, annual vacation is an escape from civilization, a busy lifestyle and everyday living conditions that hinder a person in his/her natural instincts. Vacation is a return to nature, sun and a carefree life.

1. An annual vacation spent in the place of residence with minimal lifestyle changes rarely refreshes a person mentally and physically. A change in living conditions and an escape from everyday life compensates for long-term travel (conditionally or unconditionally), poor accommodation, irregular and economically more profitable meals.
2. A completely healthy person does not care about the place of rest (mountain, sea, plain). Although a completely healthy person will (according to mental and physical condition/constitution) experience some places more pleasantly and rest more. A sick person certainly experiences any vacation differently.
3. The sea climate is not the same everywhere and does not have the same effect on the human body. For example, the northern seas have a more stimulating climate that stimulates a number of functions of the human body, the circulation of substances in the body and the work of certain glands with hormonal secretion. Southern and warmer seas (oceans) have a calming effect (especially on the vegetative nerves, precisely the nerves that do not work under human will and that control the work of all other organs).
4. The sea climate is not recommended for people with high blood pressure, blockage of blood vessels (arteriosclerosis), heart weakness or increased function of the thyroid gland (Bazed’s disease).
5. The majority of nervous-labile people also do not like the warm sea climate, especially during the hot days of July and August.
6. The warm sea climate has a particularly favorable effect on weaker (rachitic children) with enlarged lymph glands. Due to the formation of vitamin D in the skin and the activation of the circulation of calcium and phosphorus in the body, people with bone diseases (primarily bone tuberculosis), chronic wounds and fistulas that cannot heal should also be sent to warm sea areas.
7. All characteristics of the marine climate have not yet been fully explored. Thus, until recently, the prevailing opinion was that the sea is contraindicated for all people with heart diseases. Tests on the colder northern seas say that the climate in those places has a beneficial effect on people with milder heart diseases.
8. The sun and water are factors that affect the human body in the framework of the marine climate. Ultraviolet rays of the solar spectrum affect important life processes in the body. There is much more of this radiation at sea because the rays are reflected from the sea surface and from water vapor drops in the lower layers of the air. In addition, these rays are not absorbed in the smoke, dust, air that abounds in the places of residence of most people.
9. Sunbathing leads to the expansion of the blood walls in the skin, increased sweating and the expulsion of toxic components of metabolism (the circulation of matter in the body) to the breakdown of proteinaceous components (which encourage the body to defend itself and strengthen its strength to a series of effects on various glands, the neurovegetative system, the circulation of some substances etc). The sun can be harmful if a person over-sunshine and burns endlessly in the sun. The goal is often to return home with a nice dark and tanned skin color.
10. People with lung diseases (and tuberculosis) should also avoid the sun because it can cause worsening conditions and complications (bleeding is one of the most dangerous complications).
11. Bathing has a similar beneficial effect, but through other mechanisms of action. Taking a bath takes away excess heat from the body, steels the body, adapting the body to the change in the temperature of the external environment, strengthening the function of the centers (which regulate the maintenance of a constant internal body temperature), acting on the blood vessels and nerves in the skin and through them on other parts of the body.
12. Mountain air at a height of 600 to 800 meters has a beneficial effect on the respiratory organs (because it deepens breathing), on the composition of the blood (because it stimulates the bone marrow to create blood elements), on the nervous system, on the endocrine glands (beneficial effect on Bazedova diseases, i.e. enlarged thyroid glands), to convalescents after serious acute illnesses, to healthy people who want a real rest after hard work.
13. People with lung diseases (pulmonary tuberculosis) should not go to higher altitudes over 1000 meters, while these people tolerate the lower altitude climate very well. A higher altitude is not recommended for people with heart disease, rheumatic diseases, arteriosclerosis, or the elderly.
14. Bioclimatology is a part of medicine that deals with the influence of climate on the living organism. This part of medicine is constantly enriched with new experiences and knowledge, supporting the well-known fact that changes in the environment and climate have a beneficial effect in many ways.j on the human organism and on the function of individual organs in the body. This medical discipline scientifically examines all factors of climate and climate and deals with the study of treatment methods for some diseases.
