I'm allergic to any kind of pollen when the trees are in blossom, pine trees, olive trees. What can I do besides wear a mask?

Allergic rhinitis. Staying inside the house during pollen season seems like the best answer. But that's not practical. So , in addition to wearing a mask, do not forget to clean your outer clothes, accessories and shoes before getting back in your house to prevent pollen from being trapped inside the house. Taking a shower will help remove pollen adhering to your skin. Antihistamines plus nasal steroids will help.
