As a resident of Florida, you have to deal with humidity the majority of the year. For about 9 months of the year spending time outdoors can feel like being in a terrarium. But there’s more to humidity than merely feeling uncomfortable. Humidity can make it very difficult to breathe for people who already have aggravated breathing conditions. That’s why understanding humidity and how it affects your home and health is important here in the Sunshine State.
The relative humidity reading is the amount of water vapor the air holds at any given time. If the relative humidity is 67%, that means the air is 67% saturated with water vapor. You can then see how it could be difficult to breathe when humidity is high; after all, the air is much heavier. In the Tampa area, our average daily humidity is 74%—88% in the morning and 57% in the afternoon—which means that it’s the 5th-most humid city in the nation (based on the daily average).
What Humidity Does to Your Body
While a high percentage of water molecules in the air makes it difficult to breathe, it also prevents sweat from evaporating, making it more difficult for your body to cool itself. Humid air also affects how your body senses temperature. Because it’s difficult for your body to cool off, you feel hotter at lower temperatures with higher humidity than you do at higher temps with lower humidity.
Humidity and Your Home
As when you’re outside, it’s not healthy to have a high level of humidity in your home. It tends to cause musty odors, warp wood floors, increase the chance of pest infestation, cause condensation and water stains, and/or peeling or warping of wallpaper.
In addition, bacteria and viruses thrive in humid environments and stay airborne longer. The same can be said for fungi and dust mites, which affect allergy sufferers and those with respiratory issues. Finally, airborne chemicals, such as benzene, formaldehyde, and trichloroethylene, become more prevalent due to higher water vapor levels.
So with all of these potential health concerns, it’s in your best interest to make sure that the humidity levels in your home are properly maintained.
While many AC professionals will tell you that stagnant air has higher humidity levels, for most of the year in the Tampa Bay area opening your windows will only make your home more humid. Instead, you need to cool the air and regulate the temps and airflow throughout your home.
How to Safeguard Your Home Against Humidity
The ideal relative humidity in your home is between 40-50%, but the humidity can vary greatly in each room due to temperature fluctuations. One way to measure the humidity in each room is by using a small, handheld instrument called a hygrometer, which you can purchase at your local hardware store. It’s a helpful tool for determining which rooms have higher humidity readings.
By controlling the humidity by running your air conditioner, you will feel cooler at a higher temp, which also means that you will save money on energy costs. (Remember, high levels of humidity make it harder for your body to cool itself, which make you “feel” warmer than you really are.) Warmer air holds more humidity than cooler air.
Some people like to use an in-room dehumidifier, which removes moisture from the air and collects it in a tank. You can then use that water for your garden. Another option is to install a whole-house dehumidifier. However, the downside is that dehumidifiers will work constantly here in the Sunshine State. You’re better off maintaining a temperate indoor climate by using your air conditioner at a higher temperature.
That said, it’s important to set your AC unit’s fan to “automatic” because if you set it to the “on” position, the air in your home will be re-humidified. Why? Because when the condenser cycles off, air will be blown over the wet coil. In addition, you may also want to consider purchasing a unit with a variable-speed air handler, which helps purify the air in your home.
But the bottom line is that you can keep the air in your home comfortable and healthier by reducing the humidity by running your air conditioner. By doing so, and reducing the humidity, you’ll feel cooler at a higher temperature and your unit won’t be overworked.
Additional Tips for Reducing Humidity in Your Home
It’s important to note that air conditioners can only deal with the moisture they’ve been designed to remove, whether it’s recirculating the interior air or conditioning air from the outside (or both). In addition to using your air conditioner, you can reduce the humidity and moisture in your home by:
- Sealing air and duct leaks
- Making sure the drain lines and drip pans of your AC unit are clean and unclogged
- Checking for water leaks behind toilets, under bathroom and kitchen sinks, and in unfinished spaces of your home
- Running ceiling fans to increase air movement
- If your home doesn’t have them, installing vent fans in your bathrooms and kitchen
- Ensuring that your clothes dryer is vented to the outside
- In crawl spaces, using a plastic vapor barrier to cover dirt floors
- Buying plants for your house that absorb moisture, such as English Ivy and Boston ferns
- Trying not to take long hot showers or boil water on really humid days. If you take a shower, run the bathroom fan. Also, keep the door closed while showering and for half an hour after
- Outside of your home, ensuring that gutters and downspouts are clear, increasing the length of your downspouts so that they are farther from your home, watering outdoor plants only when necessary, and inclining soil away from your home so that water doesn’t pool.
Regular maintenance of your AC unit can go a long way in helping to dehumidify your home’s air. A unit that’s not working properly can compound many of the issues mentioned above.
