Winter allergies 

We think we have a cold and cough because of the cold. But this is not always the case, even in winter allergies are present.

The tree branches are dry, the grass is frozen, you don't have a cold, and yet you keep sneezing as if in the middle of a pollen season. If you really don't have a cold, you may be suffering from a winter allergy. Because of the cold weather, we spend a lot more time indoors and don't ventilate our homes much. Without fresh air, we end up breathing in micro-particles that irritate our airways and trigger allergies.

But not only! 

In the air of our homes we can find dust, fabric fibres and bacteria that make people vulnerable to allergies. There is no need to feel relieved that there are no leaves on the trees or flowers in the gardens: indoor allergens such as dust mites, mould and possible pet hair circulate in the air in our homes during the winter. In winter we spend much more time in enclosed spaces, so we are always in contact with circulating particles.

Pollution peaks in winter?

Winter is a good season for particle pollution episodes. They are mainly caused by road traffic and wood heating, combined with anticyclonic conditions. These pollution episodes are harmful to health, especially for the frail. 

The winter season accounts for an average of 90% of pollution peaks1 . They are mainly due to particles from chimney fires. When the weather is cold, people use more heating, especially chimney fires, which emit a lot of particles.
