Why Every Season Changes How Breathing Feels

People often assume their breathing is worse in one season. Usually it is worse in all four, for four different reasons.

Knowing which one you are in tells you what to actually change.

Spring: pollen

Tree pollen first, then grasses. Counts peak on dry, windy mornings and drop after rain. Practical moves: keep bedroom windows shut on high-count mornings, shower before bed to keep pollen out of the sheets, and ventilate in the evening instead of first thing.

Summer: ozone and smoke

Ground-level ozone forms in heat and sunlight, peaking mid-afternoon. Wildfire smoke can travel hundreds of miles. Both are reasons to move exercise to the early morning and to run a HEPA filter with the windows closed on bad-air days.

Autumn: mould and damp

Fallen leaves, damp gardens and the first weeks of heating in a still-humid house. Mould spores peak. Deal with damp promptly, keep bathroom fans running, and check that humidity has not crept above 60%.

Winter: dry heat

The one most people underestimate. Indoor heating can pull relative humidity below 30%, which dries the airway lining and thickens mucus. This is the season where a humidifier earns its keep, and where cold-morning tightness comes from.

Where a daily supplement fits

BreathiZen is a constant — the same drops through all four seasons, supporting everyday comfort as a background layer. The seasonal fixes above are the variables, and they address causes. Both, in that order.
