Even from the school curriculum, some will remember that hydrogen sulfide (H2S) is a colorless gaseous molecule. This substance has a rather specific smell of rotten eggs. In combination with oxygen, an explosive mixture is obtained. We also know that when combined with various oxidizing agents, hydrogen sulfide is converted to sulfur dioxide, due to this property it is used in a wide variety of industrial sectors.
In the process of repeated clinical experiments, it was possible to find out that a gaseous molecule is synthesized in human cells. A whole spectrum of important physiological processes depends on it. For the first time, the Italian doctor began to study the positive and toxic effects of hydrogen sulfide on the human body back in the 16th century. He repeatedly mentioned his discoveries in his writings.
Modern science is constantly studying the properties of H2S. Experts conduct basic research on animals and find ever new qualities of this biomolecule. It became clear that she was responsible for the transmission of neurons in the central nervous system cells, muscle contraction and regulation of blood pressure. The question of the effect of colorless gas on the environment and humans still excites many minds. We will analyze useful and toxic properties.
Being in nature
Small amounts of hydrogen sulfide are formed everywhere where putrefactive processes occur. It is present in volcanic, natural and petroleum gases, as well as in layers of the Black Sea at a depth of more than two hundred meters. The molecule can be found in the body of dead living creatures - there is a decomposition of protein compounds.
In addition, H2S is found in hot springs. The healing power of mineral waters has long been known in the medical field. In almost every health resort and dispensary, sulfide baths are actively used. The therapeutic effect of such procedures was established in 1939 with the help of special electrothermal experiments by Nesterov. The biomolecule penetrates through the skin into the body and has a positive effect on capillary circulation and nerve endings.
Hydrogen sulfide in balneology
Gas production is carried out in different cells of our body. According to experts who conducted the experimental experiments, the molecule plays an important role in the cardiovascular system. It carries out regulatory action in the arteries, participating in the regulation of pressure. Despite the presence of toxic effects, colorless gas in limited dosages also fights with numerous pathological processes.
Its deficiency leads to irreversible physiological consequences, causing Alzheimer's disease (memory loss). Hydrogen sulfide, the effect on the body of which is well studied, has bactericidal, anti-inflammatory and wound healing properties. Sulfide baths of different strengths contribute to the strengthening of protective forces, have anesthetic effect. Their therapeutic field is rather extensive. Several of these procedures significantly improve metabolism, normalize metabolic processes in the cell membrane and clear the accumulated toxins. Under the influence of biomolecules, the psychoemotional state is restored, groundless fears disappear, pressure returns to normal.
The positive effect of the bath is primarily on the coronary blood flow and musculoskeletal system. After 2 minutes of contact with gaseous hydrogen sulfide, intense reddening of the skin is observed: capillary loops expand, blood circulation improves. Mobility in diseased limbs is restored.
What pathologies does sulfide help with?
Hydrogen sulfide procedures help reduce high blood pressure. Such a conclusion is based on practical experience. Studies were conducted on rats, which were periodically injected with a portion of a solution of hydrogen sulfide. It has been observed that people suffering from hypertension have reduced plasma H2S levels.
With success, hydrogen sulfide is prescribed for diseases of the lymphatic system. The effect on the human body of a weak gas solution is favorable, it acts on the intestinal tract, gently cleanses and normalizes peristalsis. It is used for malignant tumors, intoxication as prescribed by the doctor. It is used externally in the form of inhalations and baths for the following diseases:
- Blockage of blood vessels, heart and brain defects.
- Diseases of the spine, muscles (arthrosis, rheumatism, arthritis).
- Neurological pathology.
- Gynecological problems.
- Endocrine changes.
The positive effect of hydrogen sulfide on the human body is based on a high physico-chemical reaction. Dosed concentrations of molecular particles have a pronounced therapeutic effect on the respiratory tract, mucous membranes and epithelial tissue. Sulfide procedures are carried out in dermatology for psoriasis, eczema of various etiologies, dermatitis and other diseases. However, toxicity should be kept in mind - high concentrations negatively affect health, exacerbating problems.
Hydrogen sulfide prolongs youth
Unique discoveries were made by scientists from China. They reported that it prevents early aging of hydrogen sulfide. The effect on the body of this chemical gas has been tested experimentally. It turns out that the biomolecule activates the sirtuin enzyme, which affects the production of natural antioxidants. Local procedures (compresses, baths) improve blood flow, the quality of the epidermis, and relieve skin problems (acne, inflammation). Elasticity is restored, wrinkles are smoothed out.
Who should not carry out sulfide procedures?
Despite the abundance of benefits of such baths and inhalations, nevertheless, some people are forbidden to prescribe them in order to avoid negative consequences. These include patients with angina pectoris, people with pathologies of the biliary tract, liver diseases, tuberculosis. Balneological procedures are contraindicated in the acute stage of inflammatory processes, pregnancy, myocardium. The effect of hydrogen sulfide on the human body can be negative if there is a tendency to allergies. In any case, it is advisable to conduct a conversation with the doctor and undergo a series of diagnostic tests.
The dangerous effects of hydrogen sulfide on humans
You can talk a lot about the benefits of sulfide baths, but do not forget about the high toxicity. This is a very dangerous gas that can be fatal. Hydrogen sulfide is irritating to the respiratory apparatus. A negative effect on the human body is observed at high dosages, when 0.1% of this substance is present in the atmosphere.
In a matter of minutes, suffocation overtakes, olfactory receptors are blocked . With increased concentration, death occurs. According to toxicologists, short-term action at the level of small doses is absolutely safe.
Signs of intoxication
People living near industrial plants that regularly release gaseous molecules into the atmosphere put their health at significant risk. They often suffer from chronic intoxication and dizziness. With a long stay in the contaminated region (from 0.02%), constant migraines, nausea, weakness, sulfur taste, and decreased vision are observed.
Animals also suffer from a high concentration of H2S. The negative effect of hydrogen sulfide on the dog's body has been proven: weight loss, loss of appetite, hair loss, photophobia. In humans and animals, severe cramps, pulmonary edema, and even coma are noted. Emergency medical attention required.
Hydrogen sulfide in water: effects on the human body
In drinking water should not be present more than 0.002 milligrams of gas, this figure is regulated by sanitary standards. The negative effect of hydrogen sulfide on the human body through the liquid will be imperceptible, but practically irreversible. At first, an unpleasant sweetish taste and the smell of rotten eggs will be felt, later it will pass. Dull sense of smell and taste. Damage is caused not only to the body, but also to communications, household utensils. H2S gas corrodes the metal surface, leading to rust and cracks.
