Why Winter Air Feels So Dry (And What to Do About It)
2026-01-05
If you've noticed your skin feeling tight, your lips cracking, or an annoying static shock every time you touch a doorknob—you're not imagining things. Winter in Waterloo Region brings brutally dry indoor air, and it affects more than just your comfort.
Let's break down why this happens and what you can do to feel better at home.
Why Does Winter Air Get So Dry?
Cold air simply can't hold as much moisture as warm air. When your furnace heats that cold outdoor air, the relative humidity inside your home can drop to 15–20%—drier than the Sahara Desert!
This low humidity can cause:
- Dry, itchy skin and chapped lips
- Irritated sinuses and sore throats
- Increased static electricity
- Cracking hardwood floors and furniture
- Greater susceptibility to colds and flu
The Simple Solution: A Whole-Home Humidifier
While portable humidifiers can help a single room, a whole-home humidifier connects directly to your furnace and ductwork—delivering consistent, balanced humidity throughout your entire home.
Benefits include:
- Better health: Properly humidified air helps your respiratory system fight off viruses
- More comfort: No more waking up with a dry throat or itchy skin
- Energy savings: Humid air feels warmer, so you can lower your thermostat a degree or two
- Home protection: Stable humidity prevents cracking and warping of wood furniture and floors
What's the Ideal Indoor Humidity?
During winter, aim for 30–40% relative humidity. This sweet spot keeps you comfortable without causing condensation on windows or encouraging mold growth.
Pro tip: A simple hygrometer (humidity gauge) can help you monitor levels. They're inexpensive and available at most hardware stores.
Easy Steps You Can Take Today
- Run your bathroom fan less: Hot showers add humidity—let some of that moisture circulate.
- Open dishwasher after cycle: Let the steam escape into your kitchen.
- Add houseplants: Plants release moisture through transpiration.
- Check your furnace filter: A clean filter helps your system distribute air (and humidity) more effectively.
- Consider an HRV/ERV upgrade: These ventilation systems can help balance moisture and fresh air year-round.
