We often hear about how extreme­ly low or high tem­per­a­ture, changes in atmos­pher­ic pres­sure affect a per­son­’s well-being. How­ev­er, few peo­ple think that the lev­el of humid­i­ty is an equal­ly impor­tant indi­ca­tor of the com­fort of the envi­ron­ment for our body.

What is humidity? Its optimal indicators for human activity

Humid­i­ty is a mea­sure char­ac­ter­iz­ing air sat­u­ra­tion with water vapor. When con­sid­er­ing this envi­ron­men­tal indi­ca­tor, sci­en­tists usu­al­ly have two of its dimen­sions in mind:

  • Absolute air humid­i­ty (shows the mass con­tent of water par­ti­cles in the air and is mea­sured in g/m3);
  • Rel­a­tive humid­i­ty (this para­me­ter is the ratio of the actu­al vapor pres­sure to the sat­u­rat­ed vapor pres­sure, that is, its state at which the con­den­sa­tion process begins).

Nat­u­ral­ly, it is pos­si­ble to com­pare and char­ac­ter­ize the lev­el of air humid­i­ty from a med­ical and bio­log­i­cal point of view using the “rel­a­tive humid­i­ty” indi­ca­tor. Clas­sic hygrom­e­ters and psy­chrom­e­ters (from the Greek Psy­chros — cold and metron — mea­sure) show us pre­cise­ly its lev­el.

The prin­ci­ple of oper­a­tion of these devices is famil­iar to us from school. The design of the sim­plest psy­chrom­e­ter is 2 con­nect­ed alco­hol ther­mome­ters: dry and with a spe­cial humid­i­fi­ca­tion device. The bulb of a wet ther­mome­ter is immersed in a con­tain­er of water and, as a result of evap­o­ra­tion, this ther­mome­ter cools. By com­par­ing the indi­ca­tors of the dry and wet scale of the ther­mome­ter, it is pos­si­ble to deter­mine the lev­el of rel­a­tive air humid­i­ty.

The fol­low­ing indi­ca­tors of rel­a­tive humid­i­ty are con­sid­ered accept­able for humans (depend­ing on the type of room):

  • Hos­pi­tals and hos­pi­tals — 40–55%;
  • Offices with a large amount of equip­ment — 40–60%;
  • Con­cert halls, premis­es with musi­cal instru­ments — 40–60%;
  • Muse­ums, art gal­leries, libraries — 40–60%;
  • Res­i­den­tial premis­es — 45–65%.

Human health and air humidity

Not only the phys­i­cal com­fort of a per­son depends on the opti­mal lev­el of humid­i­ty. The repro­duc­tion of many virus­es, dis­ease-caus­ing organ­isms and pathogens is direct­ly depen­dent on the val­ue of this indi­ca­tor. A study con­duct­ed by US sci­en­tists showed that if the lev­el of humid­i­ty cor­re­sponds to the norm (30–60%), there is a sharp increase in the inten­si­ty of repro­duc­tion of microor­gan­isms, fun­gi, dust mites, and mold.

All these microor­gan­isms are capa­ble of harm­ing health — from the sim­plest aller­gic reac­tions to seri­ous patho­log­i­cal changes. Let’s con­sid­er in more detail the con­se­quences for human health of low and high air humid­i­ty.

Painful symp­toms asso­ci­at­ed with low air humid­i­ty (10%):

  • Dry­ness in the nasophar­ynx, itchy eyes, nose­bleeds (dry­ing of the mucous mem­branes);
  • Rapid heart­beat and breath­ing (relat­ed to increased inten­si­ty of sweat­ing);
  • Breath­ing prob­lems, attacks of bronchial asth­ma (with a decrease in humid­i­ty, the den­si­ty of oxy­gen in the atmos­phere also decreas­es).

Dis­tur­bances in phys­i­cal well-being caused by high humid­i­ty (>85%):

  • Exac­er­ba­tion of hyper­ten­sion, car­dio­vas­cu­lar dis­eases (atmos­pher­ic pres­sure also changes with changes in humid­i­ty);
  • The risk of heat stroke (due to a vio­la­tion of heat exchange in heat­ed, sat­u­rat­ed moist air);
  • Decreased immu­ni­ty to infec­tious dis­eases (main­ly due to the risk of hypother­mia);
  • Exac­er­ba­tion of chron­ic dis­eases of sys­tems and organs (tuber­cu­lo­sis, rheuma­tism, impaired kid­ney func­tion).

How­ev­er, the great­est dan­ger for the human body is increased humid­i­ty in con­nec­tion with the repro­duc­tion of such dis­ease-caus­ing organ­isms as fun­gus and mold. Fun­gal organ­isms emit a large num­ber of tox­ic spores into the envi­ron­ment, which can become a source of var­i­ous health prob­lems:

  • Aller­gic reac­tions;
  • Headaches;
  • Dis­eases of the skin;
  • Dis­or­ders of res­pi­ra­to­ry tract func­tions (sinusi­tis, cough, pneu­mo­nia);
  • Stom­ach dis­or­der.

Nor­mal humid­i­ty is the most impor­tant fac­tor on which the vital indi­ca­tors of the human envi­ron­ment depend.

Modern methods of regulating air humidity in the room

Tech­ni­cal progress has armed us with a vari­ety of cli­mat­ic equip­ment: from ele­men­tary fans to com­plex units capa­ble of con­trol­ling the small­est char­ac­ter­is­tics of the envi­ron­ment.

For exam­ple, house­hold dehu­mid­i­fiers can eas­i­ly solve the prob­lem of high humid­i­ty in hous­es and apart­ments. Such as:

  • MYCOND Yugo Smart 16
  • Bal­lu BDH-25L
  • Cooper&Hunter CH-D005WD2-12LD
  • MYCOND Roomer Smart 12

If the task is to reg­u­late humid­i­ty in con­di­tions of increased humid­i­ty, for exam­ple, in the premis­es of a swim­ming pool, SPA-salon, gym — duct, floor, and wall dehu­mid­i­fiers are at your ser­vice:

  • Dan­therm CDP 40
  • MYCOND MBA 07 Black
  • Fair­land IDHR 60

It should be not­ed that even mod­ern indus­tri­al pro­duc­tion can­not func­tion with­out high-qual­i­ty air dehu­mid­i­fi­ca­tion units. Com­pact mobile devices and com­plex ful­ly auto­mat­ed dry­ing sys­tems are at the ser­vice of man­u­fac­tur­ers.

In our online store, you can choose a high-qual­i­ty air dry­er with a guar­an­tee from well-known Euro­pean man­u­fac­tur­ers.
