Is a Humidifier Good for Cold Weather?

As the weather gets colder, lots of people start to use humidifiers.

Is a humidifier good for cold weather?

A humidifier can be good for cold weather. It adds moisture to dry indoor air, which can ease dry skin, a stuffy nose and static electricity, and can help protect wood. Keep indoor humidity between 30% and 50% and clean the unit often, because a dirty or overused humidifier causes problems of its own.

In this article, you’ll learn everything you need to know about why humidifiers are good for cold weather.

9 Reasons a Humidifier Is Good for Cold Weather

There are at least 9 good reasons that humidifiers are good for cold weather.

Some of the reasons improve your health while others save you money and make your home more comfortable.

1) Helps With Dryer Skin

Winter can be tough on your skin. The air is dry, and the cold weather outside and the heat inside can sap your skin of moisture, leaving it feeling dry, tight, and flaky.

Humidifiers can help with all of these problems by adding moisture to the air.

And when the air is more humid, your skin loses less moisture. This can help with dry skin.

In addition, humidifiers can help with other winter ailments such as chapped lips.

2) Eases Cold Symptoms

A humidifier will not stop you from catching a cold, but it may make one more bearable. The Mayo Clinic says cool-mist humidifiers may ease a stuffy nose during a cold.

Dry air can dry out and irritate the lining of your nose and throat.

Moist air helps keep those membranes comfortable.

In addition, humidifiers can also help to thin mucus and make it easier to expel from the body.

A dirty humidifier can do the opposite. Mold and bacteria can grow in the tank and be blown into the room, so cleaning matters (see below).

3) Makes You Feel Warmer

Any time you turn on a humidifier in your house, you might notice that the air suddenly feels warmer.

The main reason is evaporation. In dry air, moisture evaporates from your skin quickly, and evaporation cools you down.

In more humid air, less moisture evaporates from your skin, so the same temperature feels warmer.

However, it’s important to remember that humidifiers only make the air feel warmer. They don’t actually increase the temperature of the air.

4) May Reduce Snoring

When the air is dry, it can cause the tissues in your nose and throat to become irritated and swollen.

This can lead to a condition known as nasal congestion, which can make it difficult to breathe and cause you to snore.

A humidifier adds moisture to the air, which may ease the dryness and congestion that can contribute to snoring. In addition, a humidifier can also help to reduce snoring by keeping the air in your throat moist.

This helps to lubricate the tissues in your throat, making it less likely that they will vibrate and produce noise.

A humidifier may help if dry air or congestion is part of the cause. It will not fix snoring that has other causes, such as sleep apnea, which needs a doctor.

5) Reduces Static Electricity

When the air in your home is too dry, it can cause static electricity and static cling.

This can be annoying and even dangerous, as static shocks can damage delicate electronics. A humidifier adds moisture to the air, reducing static electricity and static cling.

How does this work?

Dry air is a poor conductor of electricity. Charge that builds up on you, your clothes or the carpet has nowhere to go, so it stays put.

When you then touch something metal, the charge jumps across all at once, and you feel a shock.

A humidifier adds water vapor to the air, and a thin film of moisture forms on surfaces. That lets charge leak away gradually.

With less charge built up, you get fewer shocks and less static cling.

6) May Ease Dry-Air Irritation

Dry air can irritate your nose and throat, which is no help if you already have allergies.

It does this by making the mucous membranes in the nose more susceptible to irritants.

By adding moisture to the air, a humidifier can help to keep the mucous membranes lubricated.

A humidifier is not an asthma or allergy treatment, and too much humidity encourages dust mites and mold. The Mayo Clinic advises talking to a healthcare professional before using a humidifier if you or your child has asthma or allergies.

7) Protects Wood

Wood surfaces are susceptible to damage from changes in humidity.

When the air is too dry, wood can crack, warp, and become brittle.

By adding moisture to the air, humidifiers help to prevent the wood from drying out and cracking.

8) May Let You Turn the Heat Down

Because humid air feels warmer, some people find they are comfortable with the thermostat a little lower. A humidifier uses electricity too, so do not count on a lower bill.

9) Boosts Comfort

In the winter, the air is so cold and dry that it almost hurts to take a deep breath.

A room with the right humidity simply feels more comfortable.

Benefits of Humidifiers in Cold Weather

As a summary, here are the major benefits of humidifiers in cold weather:

• Feel warmer in winter
• Possibly less snoring
• Easier to breathe
• Ease a stuffy nose
• Ease dry-air irritation
• Protect your wood floors
• Protect your wood furniture
• Less static electricity
• Less dry, chapped, and flaky skin

Is a Humidifier Always Good for Cold Weather?

A humidifier can come in handy during cold weather months.

However, it is important to use a humidifier properly in order to avoid creating problems such as mold growth or excess condensation.

If you have ever had mold in your home, you know how difficult it can be to get rid of.

Not only is it unsightly, but it can also cause serious health problems for you and your family.

If that’s not enough, mold can damage your home’s structure.

To avoid that, keep indoor humidity between 30% and 50%. The EPA says not to humidify above 50%, and to turn the humidifier down or move it if water condenses on windows or walls. In very cold weather you may need a lower setting to keep the windows dry.

Keep the unit clean. The EPA advises emptying the tank, wiping it dry and refilling it every day, and cleaning portable humidifiers every third day. Use distilled water, because ultrasonic and impeller humidifiers can spread minerals and microorganisms from the tank into the air.

Avoid placing the humidifier too close to walls or furniture, as this can cause damage. By following these simple tips, you can enjoy the benefits of a humidifier without inadvertently creating problems.

How to Choose a Humidifier for Cold Weather

What is the best humidifier for winter?

To choose the right one, you’ll need to consider:

• The size of the room
• Coverage
• The type of humidifier
• The output
• The runtime
• Noise level
• Ease of use

First, decide what type of humidifier you need.

Humidifiers come in two main kinds. Cool-mist humidifiers include ultrasonic models, which use sound waves, impeller models, which use a rotating disk, and evaporators, which blow air through a wet wick. Warm-mist humidifiers, also called steam vaporizers, heat water to make steam. The Mayo Clinic advises against steam vaporizers in homes with children, because the hot water can cause burns if spilled.

Ultrasonic models are quiet, which suits bedrooms, but use distilled water in them so they do not spray minerals into the air.

Next, consider the size of the unit. Humidifiers come in all different shapes and sizes, so it’s important to choose one that will be able to cover the area you need it to.

Final Thoughts: Is a Humidifier Good for Cold Weather?

The bottom line is that a humidifier is good for cold weather when it is used properly.

Keep the humidity between 30% and 50%, use distilled water and clean the unit every few days.
