For what air rooms? Everyone well knows
how hard long time to be in not aired room: from closeness the head begins to hurt, slackness, weakness, drowsiness appears … Many explain it with a lack of oxygen. Also are mistaken. In air of badly ventilated room the content of oxygen decreases so slightly that it cannot make any negative impact on an organism.
Responsible is the whole complex of factors, and, according to many scientists, first of all carbonic acid. Experiences show that in not aired room where there are people, the content of carbonic acid is exceeded more than by 20 times! In it there is nothing surprising - carbonic acid is emitted with the exhaled air. Carbonic acid - the powerful regulator of function of breath and blood circulation.
It, in turn, can cause feeling of weight in the head and a headache, a condition of discomfort, fast fatigue. Except it, we inhale also so-called harmful impurity, for example, carbon monoxide, or carbon monoxide (WITH). During the day the person can allocate in the atmosphere surrounding him up to 10 - 15 milliliters WITH. And if in many people, and it is long is not aired, the content in air of carbon monoxide increases, and it can begin to have toxic effect on an organism.
Getting through lungs to blood, molecules of carbon monoxide take root into erythrocytes, force out oxygen from its connections with hemoglobin, forming carboxyhemoglobin. At the same time oxygen transport to fabrics is broken that leads to development of oxygen insufficiency - a hypoxia. Besides, carbon monoxide breaks process of biological oxidation in fabrics, causing oxygen starvation in an organism why all its systems suffer and many functions are broken.
Air of not aired rooms contain also other harmful impurity: methane, ammonia, aldehydes, ketones. They come to the air surrounding us from lungs at breath (all with the exhaled air 149 substances, and also from a skin surface, with sweat evaporation 271 substances are emitted).
Aldehydes, for example, systematically entering interaction with proteins of fabrics, can become the reason of pathological changes of internals, first of all, of respiratory organs. They have an adverse effect on activity of the central nervous system, and from - for it there is an increased fatigue, a headache.
Leads to adverse effects also ammonia inhalation - a chemical compound of nitrogen with hydrogen. In air of badly aired room the content of this substance, of course, is not so considerable to cause a typical picture of poisoning. But the trouble is that impact of ammonia on an organism is strengthened by other harmful impurity in air. And such double or threefold blow is already rather expressed: breath increase, increase of arterial pressure, irritation of mucous membranes of the top airways, slackness, drowsiness, working capacity decrease, headache can become its consequences.
Considerable harm to an organism is done by a lack of air of not ventilated rooms of negatively charged ions, so, and surplus of ions positive. Already it is not necessary to prove that negative ions which there is a lot of in fresh air tone up vegetative nervous system through the peripheral receptors which are stuffed up in skin, in mucous membranes of the top airways. As a result the vitality raises, cheerfulness, good mood appears.
A conclusion from everything told is clear: rooms in which we live, we work, we have a rest, it is necessary to air carefully and systematically. To happen as often as possible in the fresh air, in the country. Are present at the atmosphere an ozone molecule, or triatomic oxygen which especially actively stimulate function of the central nervous system and processes of biological oxidation.
When we are in a garden, in park, in the wood, we inhale biologically active agents emitted by plants - phytoncides. They possess the toning and disinfecting action. Getting into airways, phytoncides not only clear bronchial tubes, lungs of pathogenic microorganisms, but also raise a tone of all organism.
