When winter arrives, the air both outside and inside becomes noticeably drier. In the office, this can lead to dry skin, irritated eyes, static electricity, and a general feeling of stuffiness. Dry air can also make it easier to catch colds, as it dries out the mucous membranes in your nose and throat. Fortunately, there are several simple ways to improve indoor air quality so you and your coworkers can breathe easier throughout the colder months.

Why Does the Air Get So Dry in Winter?

Cold air naturally holds less moisture than warm air. When we heat our offices without adding humidity, the indoor relative humidity can drop below 30%—well under the recommended range of 40–60%. This is especially common in modern, well-insulated buildings with efficient ventilation systems.

Dry air doesn’t just affect people; it can also impact office materials. Wooden furniture may crack, and paper can curl or become brittle. Maintaining balanced humidity helps protect both employee comfort and office furnishings.

Ventilate—But Do It Smartly

It might seem counterintuitive, but letting in fresh air is part of the solution. Briefly opening windows allows stale, dry air to be replaced with fresher outdoor air, which often contains more moisture, even on cold days.

• Air out the office two to three times a day for 5–10 minutes with cross-ventilation.
• Avoid leaving windows slightly open all day—it wastes heat and increases energy costs.
• Keep the indoor temperature steady, around 68–72°F, to maintain a comfortable balance.

Add Moisture Naturally

You can increase humidity in simple, low-cost ways without investing in expensive equipment.

• Plants: Green plants like peace lilies, ferns, and rubber plants release moisture through transpiration and help purify the air.
• Water bowls: Place small bowls of water near heating vents or on windowsills. As the water evaporates, it gently raises humidity levels.
• Damp cloths: Hanging a damp towel or cloth in a corner of the office can provide a quick, temporary boost in moisture.

These methods work especially well in smaller offices or home workspaces where you can control the environment more easily.

Consider a Humidifier—But Use It Properly

In larger offices or open-plan spaces, a humidifier can be an effective solution. It adds moisture directly to the air and can be set to maintain a specific humidity level. However, proper use is essential:

• Clean the humidifier regularly to prevent bacteria or mold growth.
• Use distilled or filtered water when possible.
• Monitor humidity with a hygrometer—levels above 60% can encourage mold and dust mites.

A small digital hygrometer is an inexpensive tool that helps you keep humidity in the ideal range.

Be Mindful of Heat Sources

Heaters, radiators, and space heaters can quickly dry out the air. You can reduce their impact by:

• Avoiding desks placed directly in front of heating vents or radiators.
• Using thermostats to maintain a consistent temperature.
• Ensuring that warm air isn’t blowing directly on people or plants.

If your office has a central HVAC system, consider having it serviced. Some systems can be adjusted or upgraded to retain more moisture in the air.

Small Habits That Make a Big Difference

Beyond technical fixes, everyday habits can help you feel more comfortable:

• Drink plenty of water to stay hydrated.
• Use moisturizer and lip balm to protect your skin and lips.
• Avoid excessive use of scented products or harsh cleaners that can irritate dry airways.
• Take short breaks away from your screen—dry air can worsen eye strain.

When everyone in the office contributes small efforts, the overall comfort and energy levels improve noticeably.
