It’s a safe assumption that most people know what a muggy day feels like – it’s not only sweltering hot, but the air feels thick and moist as well. That’s due to humidity.
For those who don’t know what humidity is, it’s a measurement of moisture in the air. Humidity can negatively affect people when there is too much or too little of it, especially people with breathing conditions such as asthma.
You’ve probably heard the term used mostly on weather reports. From eHow on YouTube, here is a brief video giving a more in-depth explanation of what humidity is:

With a clearer idea of what humidity is, it’s a much smaller step to understanding the importance of it. Humidity can have negative effects on your health if its levels are too high or low, especially for those suffering from the likes of asthma.
In an article from Diffen.com these health effects are clarified and the consequences of high or low humidity are explained:
Humidifier vs. Dehumidifier
Relative humidity of 30 to 50% is recommended for good health. This is challenging in extreme conditions such as dry heat or too much moisture.
A humidifier is used to increase the level of humidity in the air and a dehumidifier reduces the humidity level of the air. A hygrometer can be used to measure the humidity of a particular area to decide whether a humidifier or dehumidifier is required. […]
Dry, itchy skin and chapped lips are common in areas with low humidity. Humidity levels over 50% result in the growth of mold spores, bacteria, and dust mites. 40% humidity is required for musical instruments to prevent finishes from crazing or cracking. […]
A place with higher temperature and high relative humidity needs moisture to be pulled out of air. Moist air helps the growth of mold, dust mites and spores which aggravate allergies and asthma. A dehumidifier removes moisture from air and is suited for this climate.
Humidity doesn’t just affect your health though, it can also cause damage to your house. A high humidity level is especially harmful, causing wood to rot and mold and bacteria to thrive.
From CriticalCactus.com these effects are explained in more detail:
10 Reasons Why Ideal Home Humidity Levels Prevent Sickness and High Costs
When indoor humidity levels are too high, condensation on windows and walls starts to cause structural damage. Damage to the house manifests in wood rot, molds, damp spots, and corroding furniture.
Costly damage caused by moisture that builds up can occur between the walls and ceilings, paint may start to peel as well as permanent wood warping/damage.Water can also seep in between window molding and weather stripping, which can either freeze or expand depending on external temperatures, and cause damage that way.
Older homes and apartment complexes may not be as well equipped with proper insulation and ventilation and are less energy efficient. Such homes may be more susceptible to holding a surplus of moisture. Poorly insulated walls, ceilings and windows can retain an excess of moisture within the home.
Buildings that are more structurally sound are generally able to retain proper heat and moisture levels. On the other hand, modern homes are insulated to trap heat, doors and windows are weatherstripped and caulked to lock out cold outside air.
Your health and quality of life should not be compromised by water vapor. If you think your humidity levels might not be within the best range, or if you’re simply curious, there are humidity testers for measuring the level in your home.
With the results, you can decide if you need a humidifier or dehumidifier to make your home a more comfortable and healthy place for yourself and your family.
