Autumn has arrived, bringing with it the cold and flu season. Mornings are turning chilly, indoor air feels dry, and viruses are once again circulating in homes, workplaces and schools. Many people first notice a slight scratch in the throat, a stuffy nose or that breathing feels heavier than usual.
That’s the moment to pause for a breath – quite literally.
Why Do the Airways Become Irritated During Cold Season?
The mucous membranes in your airways are the body’s own first line of defence against pathogens. When the air is cold or indoor air too dry, the membranes lose moisture and their protective function weakens. This makes it easier for viruses to settle and can make breathing feel less comfortable.

Warm, moist steam is a simple yet effective way to support the wellbeing of the mucous membranes. It moisturises, warms and can help support the body’s natural defence response through what’s known as a hyperthermic reaction, a controlled rise in airway temperature. This gentle local warming is the body’s natural way to activate its defence mechanisms, without the strain of a full fever.
WellO2 – More Than Steam Inhalation
WellO2 is a Finnish innovation that combines warm steam with adjustable breathing resistance in one exercise.
When you breathe through the device, the warm steam moisturises and soothes the airways, while the resistance trains both the exhalation and inhalation muscles and supports natural airflow.
Just a few minutes of daily training can help to
- support comfortable breathing during the cold season
- keep the airways moisturised in dry indoor air
- relax breathing and calm the mind after a busy day
The Nasal Mask – For When You Feel Congested
The nasal mask, included with every WellO2 device, allows you to breathe the warm steam directly through your nose. This can be especially helpful when your nose feels blocked or your sinuses feel heavy. The steam gently moisturises the nasal membranes and helps clear the airways naturally, without medication or chemicals.
Many users like to do their WellO2 routine before bedtime to make nasal breathing easier and promote more restful sleep.

A Natural Way to Care for Your Breathing
During the cold season, most of us remember handwashing and vitamins, but the wellbeing of our airways is often overlooked. Yet the quality of our breathing affects everything – recovery, energy levels and sleep.
WellO2 offers an easy, natural way to take care of your breathing every day. Warm steam, calm breathing and just a few minutes for yourself can do wonders for both body and mind.
