What is in the air in November? Household allergens in Szczecin

November is a month when the pollen season is already over. If your runny nose and sneezing do not go away anyway, the source is most often household allergens — dust mites, moulds and pet dander. These are year-round allergens, but in autumn and winter they make themselves felt twice as strongly.

In brief

• Main allergens of November: house dust mites, moulds (indoor and on damp leaves), pet dander and skin flakes.
• Plant pollen: practically absent.
• Typical symptoms: persistent runny nose, blocked nose, sneezing, itchy eyes — around the clock, worse in the morning.
• How to cope: bedroom hygiene, humidity control, HEPA filters; get tested if you have symptoms.

What triggers allergies in November

House dust mites

This is the most important allergen of the cold season. Dust mites live in bedding, mattresses, carpets and upholstery, and the heating season favours them. Symptoms can be year-round, but now — when we spend more time at home — they are more noticeable, especially after waking up.

Moulds

Moulds develop both indoors (bathrooms, kitchens, damp rooms) and outdoors — on rotting, wet leaves. Their spores cause symptoms similar to pollen allergy, often persistent.

Pet dander and skin flakes

Closed windows and more time indoors increase contact with pet allergens. In sensitive people this worsens symptoms.

How to ease symptoms in November

• Wash bedding at 60°C and vacuum regularly (a vacuum cleaner with a HEPA filter).
• Limit "dust collectors" — carpets, soft toys, heavy curtains in the bedroom.
• Control humidity and air your home to limit moulds.
• Consider an air purifier with a HEPA filter in the bedroom.

If symptoms last throughout autumn and winter, it is worth finding out exactly what you are allergic to. At the AGAMED clinic in Szczecin we carry out allergy tests covering dust mites, moulds and pet allergens — painless, with the result right away. Everyone reacts differently, so if your symptoms are severe it is also worth consulting an allergist.

November 2026: the heating season and household allergens

When we switch on the heating and close the windows, dust — and with it dust mite residues — is stirred up more easily in the home, and dampness in the bathroom, kitchen and behind wardrobes favours moulds. That is why a runny nose that we associate with pollen in summer often has its source in our own home in autumn.

A 10-minute check

• Measure the humidity with a simple hygrometer — a range of about 40–60% is usually considered comfortable.
• Look in the critical spots: window corners, bathroom grout, the back of wardrobes against exterior walls.
• Note when your symptoms are strongest (in the morning, after cleaning, after coming home, in contact with a pet). Such a note makes the conversation during the visit much easier.

Why November is a good time for a test

Outside the pollen season it is easier to tell symptoms related to the home from those caused by plants. How to prepare for a test is described in the article how to prepare for an allergy test, and the course of desensitisation in the article desensitisation with bioresonance step by step. You will find indicative costs and what they consist of in the article how much does bioresonance cost, and current rates in the price list. We treat the result of a bioresonance test as indicative information, not a diagnosis; severe or worrying symptoms are worth discussing with a doctor.

What next

In December new factors join in, including dust from decorations and a real Christmas tree — we describe them in the article What is in the air in December.

Frequently asked questions

If nothing is pollinating, why do I have a runny nose?

Because the symptoms are caused by household allergens — dust mites, moulds and pet dander — not pollen. They are active all year round and more troublesome in autumn.

How can I reduce dust mites in the bedroom?

Wash bedding at a high temperature, use anti-allergy covers, vacuum with a HEPA filter and keep humidity moderate.

When should I get tested?

November is a convenient time — you are outside the pollen season. We carry out tests at AGAMED all year round. Book a visit: 519 055 858.
