If the air in your area is generally particularly dry, it can cause problems. These problems can be respiratory and sinus related, and generally, excessively dry air does not lend itself particularly well to comfort, whether outside or within your own home. It is ultimately best to invest in a whole household air humidifier if you find yourself in an excessively dry climate. Whole household air humidifiers can alleviate all sorts of symptoms of excessively dry air, of course, you won’t have excessively dry skin if you are in an environment that has proper humidity levels, but furthermore, you will easily suffer from less nosebleeds and respiratory problems. If you have a head cold, for example, moist air is particularly more beneficial than excessively dry air when it comes to helping you breathe. I have also personally found that a whole household humidifier helps me feel warmer in the winter time when I use it in conjunction with my boiler. I find that I could turn down the temperature a little lower because the moisture in the air makes me feel warmer at a lower temperature than if the air was dry, but humidifiers can even protect against respiratory infections, which can be exacerbated by excessively dry air. There are so various reasons to invest in a whole household air humidifier! Perhaps you should speak with a representative from your local heating and a/c supplier if you live in a dry climate, to see if they have any humidifiers available to you!
