Furnaces run hard through a prairie winter, and the CDA points to cold weather plus dry, heated indoor air as the most common cause of dry skin. Adding a little moisture back to the air is one of the simplest comfort upgrades you can make. The trick is not overdoing it.

What humidity should you aim for?

Health Canada's healthy home guide suggests keeping indoor humidity between 30% and 50%. For winter specifically, Health Canada suggests around 30%, because higher humidity in cold weather can cause condensation on windows and lead to mould.

Step 1: Measure first with a hygrometer

You can't manage what you can't see. An inexpensive digital hygrometer shows your room's humidity so you only run a humidifier when it's actually needed, and notice if it's creeping too high (condensation on windows is a sign).

Step 2: Use a cool-mist humidifier the safe way

Health Canada says portable cool-mist humidifiers are safe when used as the maker directs, and gives these tips:

• Empty leftover water every time you turn it off. Don't let water sit between uses.
• Clean and disinfect the reservoir regularly, following the manufacturer's instructions.
• Place it in a central location, and keep it out of the bedroom, especially overnight.

Step 3: Pair it with your routine

Humidity helps the air. Your skin still needs a rich cream on damp skin after washing, and a fragrance-free routine. Our 3-step winter routine covers it.

Quick checklist

• Aim for around 30% indoor humidity in winter.
• Check a hygrometer daily for the first week.
• Empty, clean, refill only when you'll use it.
• Wipe away any window condensation and lower the setting if you see it.
