Is Winter Air Too Dry? Here’s How Oxygen Users Can Stay Comfortable

Winter is often hard for people with respiratory issues, and it can be even more difficult for those who use supplemental oxygen. When it gets cold, heaters run more often, and the air outside becomes drier. This takes moisture from the air and your airways, causing a dry nose and throat, cracked skin, more coughing, and general discomfort when breathing.

For oxygen users, dry air irritation isn’t just unpleasant—it can interfere with adherence to oxygen therapy, increase the risk of infection, and make already-sensitive airways feel even more inflamed. The good news is that with the right strategies and equipment, you can significantly reduce dryness and stay comfortable all winter long.

This guide explains how winter dryness affects oxygen users, which humidity solutions are most helpful, and how you can keep your breathing environment healthy all season.

What Winter Air Means for Oxygen Users

Cold air holds less moisture. In winter, humidity can drop to 20%, well below the recommended indoor range of 30 to 50%. Heaters also blow warm, dry air through your home, making the air even drier.

For people using oxygen, the airflow from the equipment can worsen dryness. Whether you use a portable or a stationary oxygen concentrator, the oxygen can dry out your nasal passages. Here’s why:

1. Oxygen therapy increases airflow to the nose

Even at low flow rates, a continuous stream of oxygen can irritate the lining of the nasal passages, pulling moisture away from the mucous membranes.

2. Dry nasal passages become more sensitive

A dry nose is more prone to:

• Nosebleeds
• Crusting inside the nostrils
• Burning sensations
• Congestion and swelling

3. Dryness can worsen coughing and breathlessness

When your throat and airways lose moisture, they can become irritated and inflamed, which makes breathing less comfortable.

4. Viruses spread more easily in dry air

Winter is already the season for colds and flu, and dry air makes your body’s natural mucus barrier weaker. This leaves you more open to getting sick, which is something oxygen users want to avoid.

Knowing why dry air is a problem is the first step to fixing it. Here are some practical ways to stay comfortable and avoid symptoms during winter.

 

Tip #1: Use a Room Humidifier—But Choose the Right Type

A room humidifier is one of the best and most common ways to add moisture to indoor air. However, not all humidifiers are the same, so picking the right one is important for your safety and comfort.

Cool-Mist Humidifiers (Best Choice for Oxygen Users)

Cool-mist humidifiers add moisture to the air without heating the water. They are usually safer to use with oxygen equipment because they don’t make warm vapor or carry a burn risk. They also use less energy and work well in medium to large rooms.

Warm-Mist Humidifiers (Use With Caution)

Warm-mist humidifiers boil water to make steam. They can feel soothing, but there are some important warnings to keep in mind:

• They may create warm air that can overheat a room already warmed by heaters.
• They pose a burn risk if knocked over.
• Keep them far from oxygen equipment, since oxygen-rich areas should not be near heat sources.

How to Use Humidifiers Safely

• Place the humidifier at least 6 to 10 feet away from your oxygen concentrator or portable oxygen concentrator.
• Clean it every 1–3 days to prevent mold or bacterial buildup.
• Use distilled water to avoid mineral residue and “white dust.”
• Use a hygrometer to check indoor humidity and try to keep it between 30 and 50 percent.

Tip #2: Consider Oxygen Humidifier Bottles (For Higher Flow Rates)

Many stationary oxygen concentrators let you attach a humidifier bottle, which adds moisture right to the oxygen before it reaches your nasal cannula. These bottles are helpful if you are using:

• Continuous flow oxygen at 3 LPM or higher
• Oxygen for long durations throughout the day
• A stationary concentrator at home rather than a POC

Portable oxygen concentrators usually do not work with humidifier bottles because of their small size and pulse-dose delivery, which do not support this feature.

If You Use a Humidifier Bottle:

• Use only sterile or distilled water.
• Empty and refill it daily.
• Wash it with warm, soapy water and let it air dry.
• Replace the bottle according to manufacturer recommendations (usually every 30 days).

A humidifier bottle can make a dramatic difference for those who experience nasal dryness or discomfort from continuous-flow oxygen. The irritated, direct moisture to the nose can offer immediate and lasting relief.

Tip #3: Use Nasal Moisturizers and Saline Sprays

When your nasal passages feel irritated, direct moisture to the nose can offer immediate and lasting relief.

Saline Nasal Spray

A basic saline spray helps moisten dry nasal passages and can be used several times a day. It is drug-free and safe for people using oxygen.

Nasal Gel or Moisturizing Ointment

Saline gels or moisturizing nasal ointments can create a protective layer inside your nose. Always pick water-based products, not oil-based or petroleum ones, because oils are not safe for people using oxygen.

Saline Rinses

If you have a lot of congestion or crusting, a saline rinse or neti pot can help clear your nasal passages. Always use distilled or sterile water.

Tip #4: Hydrate from the Inside Out

It’s easy to forget to drink enough water in winter, but staying hydrated is one of the simplest ways to fight dryness.

Aim for steady hydration throughout the day

Herbal teas, warm water with lemon, and room-temperature water all help. Try to avoid drinks that dry you out, such as:

• Excess caffeinated beverages
• Alcohol
• Sugary drinks

Eating foods with high water content, like soups, citrus fruits, melons, cucumbers, and leafy greens, can also help you stay hydrated.

When you are well hydrated, your nose, throat, and lungs are better protected from dryness and irritation.

Tip #5: Protect Your Skin from Irritation

People who use oxygen often notice dry skin where the nasal cannula touches. This can feel even worse in winter.

To prevent irritation:

• Use cannula-friendly moisturizing lotions that are water-based.
• Add foam cannula covers for a softer fit.
• Replace your nasal cannula every 2 to 4 weeks, or sooner if it becomes stiff.
• Avoid using petroleum jelly on the face or in the nostrils; it is not safe around oxygen.

Caring for the skin where your cannula sits will help you use oxygen more comfortably and regularly during winter.

Tip #6: Maintain Good Air Circulation Indoors

Humidifiers add moisture, but if air is not moving, rooms can feel stuffy and uncomfortable. It’s important to keep fresh air circulating, even in winter.

Ways to improve circulation:

• Set ceiling fans to a low, reverse setting to move warm air down into the room gently.
• Crack a window for 10–15 minutes each day if the outside air quality is good.
• Keep vents unblocked and filters clean.
• Position your oxygen concentrator in a well-ventilated area.

Good airflow helps spread humidity evenly and keeps areas from getting too damp or too dry.

Tip #7: Don’t Over-Humidify (Too Much Moisture Can Be a Problem!)

Dry air can irritate, but overly humid air can lead to mold, dust mites, and bacteria, which can worsen breathing problems, especially for people with COPD or asthma.

Keep humidity between 30 and 50 percent. Levels above 55 percent can be harmful, especially in winter when windows are closed and ventilation is reduced.

A basic hygrometer costs less than $15 and gives you quick readings, so you can easily adjust your home’s humidity.

Tip #8: Review Your Oxygen Equipment Setup

Sometimes, winter dryness is caused by how your oxygen equipment is set up or used.

Ask yourself:

• Is your flow rate set correctly, or are you using more oxygen than needed?
• Has it been a while since your equipment was serviced or your filters replaced?
• Are you switching between indoor and portable oxygen often?

A quick check of your equipment or a talk with your respiratory specialist can make a big difference in your comfort.
