Winter has arrived! It might have brought with it some unusual phenomena to your home. Static electricity may cause your hair to stand on end or your laundry to stick together, or your skin may suddenly feel like sandpaper. Believe it or not, there's actually a completely normal explanation for these occurrences. Chances are good that you're dealing with a dry house, which tends to happen when the outdoor temperatures drop.

Your house feels so dry because of a loss of humidity that can occur for a number of reasons. Your doors and windows may have minor leaks that are letting the cold air in, or your home's insulation might need replacing. The good news? Whatever the underlying cause of your dry house may be, there are plenty of easy solutions to bring its humidity levels back in balance.

What Are the Symptoms of a Dry Home?

While the most obvious symptom of a dry house is dry indoor air, you may also notice increased static electricity on your hair or clothing, or your skin and eyes might feel itchy and dry. Additionally, extended periods of dry indoor air can sometimes trigger physical issues such as asthma, nosebleeds, chapped lips and coughing. In some cases, dry air can damage wood paneling, flooring and furniture, as wood naturally releases and absorbs moisture.

Why Does My House Feel so Dry?

A lack of humidity is the most likely scenario for why your house feels so dry. Cold weather is a common cause of low indoor humidity, as cold air is naturally less humid than warm air. Poor insulation and gaps or cracks in doors and windows allow more cold air to enter your home, which can increase dryness levels.

Your home's indoor air may also feel overly dry if your HVAC system is out of whack. Dirty or clogged air filters in your furnace or air conditioning system can prevent air from flowing as it should, leading to an overly dry environment. Clogged HVAC ductwork is another common issue that may contribute to a dry house, and you may even notice dust buildup on surfaces or particles floating in your home's circulating air.

Why Your House Feels Especially Dry During the Winter

Outside: Low Relative Humidity

The relative humidity of the outside world is generally much lower in the winter because cold air holds a lot less moisture than hot air. So, if you live in a climate that experiences mildly cold to extremely cold winters, you can expect that the humidity of your home will be lower during the winter months.

Inside: Running Your Furnace

The other contributing factor to dry winter air is running your gas furnace. A standard gas furnace needs air for the combustion process (which creates heat). So, if your furnace is drawing on all that cold, dry air, it's going spit out warm, dry air.

One of the easiest ways to add moisture to your home and prevent overly dry air is to install a whole-house humidifier or set up personal humidifiers in the affected rooms of your home. Personal humidifiers are available through a variety of retailers, and whole-house humidifiers are usually installed by licensed HVAC technicians. As a humidifier runs, it releases moisture into the surrounding air. Personal humidifiers should start balancing out the air within 30 minutes, while whole-house humidifiers typically start working within an hour of installation.

If your house is dry due to clogged air filters or other issues with your furnace or air conditioner, it's important to schedule service with a professional HVAC company. Your HVAC technician can perform the necessary repairs to get your system running properly, which may also help eliminate the dryness in your home. They can also conduct air quality tests and advise on solutions to help keep your indoor air balanced and comfortable throughout the seasons.

Here are a few DIY solutions that may help increase humidity inside the home:

Hang wet towels and clothing. Hanging wet towels and clothing throughout your home is a cost-effective way to humidify your space. As the clothes and towels dry and the water evaporates, the dry air will naturally humidify.
Invest in indoor plants. Plants such as aloe vera and Boston ferns work well to add humidity to indoor spaces by releasing natural water vapors.
Seal cracks and gaps. Sealing up cracks, doorways and windows may help prevent the humidity from escaping your house. Some easy sealing solutions include applying weatherstripping to window and door openings and filling gaps with caulking.

To keep your home's indoor air balanced in the future, scheduling periodic HVAC maintenance service can help ensure your air filters are clean and the rest of your system is working as it should. During the winter months, make sure all your doors and windows are properly sealed, and keep the circulating air free of irritants by dusting regularly.
