humidifier at first sight can seem a senseless thing which only takes the place in the house. However all of us know that the person almost for eighty percent consists of water, so, humidity level in the atmosphere plays not the last role in our life. Not without reason holidays people seek to spend a vacation or days off on the bank of the sea, the river or the lake. Changes of level of moisture in air are cardinally changed by health of the person. At continuous differences of this indicator, decrease in immunity, increases in fatigue, a problem with skin, drowsiness, headaches and many other things is possible.
The optimum level of humidity in the atmosphere when the person feels most comfortably, is from forty to sixty percent. Humidity level considerably changes when the person moves from the street to the room. Especially heavy differences of humidity happen during the winter period when under the influence of heating moisture begins to evaporate much more promptly. It can be determined by such physiological signs as dryness in a throat, drying of lips and a mouth, dry skin of face and hands. If the person carries contact lenses, then long stay in places with low humidity can cause the strengthened drying of lenses that is fraught with many problems – from discomfort before deterioration in a condition of eyes. And if the short-term impact of change of level of humidity does not pose special threat, then constant exposure to these processes does serious harm to our organism.
It was also by practical consideration established that in dry air much more hazardous substances concentrate. In particular it concerns dust which in an arid climate attacks mucous membranes of the person. As a result of exchange processes, skin loses moisture about a half of liter within a day, and in winter time - to liter. Thereof there is a problem, the most relevant for female audience - dryness of skin. Various cream, the lotions and masks intended for preservation of youth of skin fight only against the investigation, but not against the reason. Though for reduction of loss of moisture it is quite enough to increase humidity of air indoors.
Especially strongly small children suffer from differences of humidity. Their high sensitivity to weather conditions forces parents to support a certain microclimate indoors. For favorable development of the child the humidity level indoors should not be lower than fifty percent. The conducted researches showed that the low humidity of air has an adverse effect, especially for children of early age. Too dry air indoors overdries skin, thereby reducing protective properties and creating discomfort for the kid. At the lowered humidity even at healthy children changes of the daily mode of function of kidneys and development of dysbacteriosis are possible. If the child already has problems with health, then the arid climate will only provoke a recurrence, will reduce efficiency of traditionally applied treatment methods.
It is even worse, than children suffer from change of level of humidity elderly people. Besides decrease in immunity at aged people old diseases become aggravated. Presence at air of a large amount of dust and different allergens causes allergic reactions - breath violations, cold, nose and throat pains and other unpleasant symptoms.
To stabilize humidity level indoors during any season it is enough to establish a humidifier. But before buying this device useful will be to get acquainted with the existing models and to study their merits and demerits.
The simplest in a design and the principle of work are humidifiers of ventilatory type. In these humidifiers which design is checked by time the evaporation happens by a traditional method. Moisture gradually evaporates from the container with water. The area of evaporation is increased due to application of special replaceable sponges which effectively absorb moisture from tanks, and further evaporate it in air. The fan blows in sponges, increasing a consumption of air and, thereby, leading to effective evaporation of moisture.
There are also humidifiers working by the principle of hot steam. This type of humidifiers increases humidity in the room, heating water to boiling temperature. Humidifiers of this type work a little shumny other types and also consume more electric power due to boiling process. Periodically cleaning of a heating element from a scum is required.
Ultrasonic humidifiers are the most modern and effective. This type of humidifiers differs in the compact sizes and the most various, sometimes in fancy design. Evaporation happens due to high-frequency fluctuations of a special membrane which forcibly evaporates water which has temperature of cold water therefore such type of evaporation often call cold steam. It is possible to carry constant visible white cold steam from the device to relative shortcomings of such humidifiers and possible formation of a white raid on surfaces in several weeks after work of a humidifier.
