The nervous system is one of the most vulnerable parts of our body when staying at high temperature This is caused on the one hand by the direct impact of heat, especially on the skull, and on the other hand - from the indirect damage that can contribute to dehydration, loss of s alts and minerals, etc.
Of course, the tolerance of the nervous system is different in the inhabitants of different climatic zones, both due to a purely physiological difference (color and structure of the skin, hair, eyes) and due to permanently established and generally accepted norms of life, clothing, type of meal, rest, etc
It is no coincidence that at high air temperatures and the inability to adequately cool down, there is an increased incidence and more severe course of some neurological diseases - for example, brain stroke. High temperatures, overheating or overcooling can activate the development of infections by so-called "conditionally pathogenic microorganisms", which can lead to inflammation of the brain (meningitis and encephalitis) or to the occurrence and exacerbation of autoimmune diseases of the nervous system.
Almost classic are the cases of facial paresis (facialis) after exposure to a cold current, often from a poorly directed air conditioner. Last but not least, while warm and sunny weather usually leads to an optimistic and uplifted mood, unusually high heat is associated with increased irritability, apathy and even depressed mood and behavior.
Protecting the nervous system from the adverse effects of high temperatures requires, first of all, protection from direct sunlight on the eyes and head. For a long time, the wearing of quality sunglasses was not only accepted as a beautiful accessory, but above all as an additional means of protecting the retina of the eyes, which is made up of nerve receptor cells. It is mandatory to avoid overheating of the head from direct sunlight, as if it is not possible to stay indoors, then a hat should be worn, preferably made of breathable natural material. This is especially important for patients with epilepsy, survivors of brain strokes, traumatic brain injuries, meningitis, etc., as well as for children. Directly cooling the heated head by getting it wet, for example, may also come into consideration in some cases.
In case of extreme overheating of the body, the so-called "heat" or "sunstroke" develops - conditions that can be life-threatening, and the leading symptoms in them are on the part of the central nervous system.
It is extremely important to take extra fluids on warm days, and this should be objectified - i.e., to drink more bottles or glasses than we are used to.
It should be borne in mind that on very warm days, almost half of the fluid intake can be lost through sweating. And, while he althy kidneys manage to retain all the useful s alts and only the unnecessary ones are excreted through the urine, a lot of valuable s alts and minerals, especially necessary for the proper functioning of the nervous system, are lost during sweating. Therefore, with increased sweating, it is useful to take additional s alts and minerals.
Both natural solutions (airyan, water with lemons or other fruits dissolved in it) and so-called "isotonic drinks" are suitable. The available combined preparations of vitamins and minerals in prophylactic doses should not be neglected.
And finally - do not forget, in case of symptoms of overheating - headache, nausea, vomiting, followed by drowsiness and lethargy - do not self-medicate, but seek urgent medical help!
