Neti pot, indeed, and I'm gonna hafta start showerinng before bed as well as in the a.m. Hadn't thought of that pollen-in-hair-in-pillow-in-face bit. I keep a fine-mist spritzer of water, witch hazel and lavender essential oil to spray my face when it's itchy and puffy. Soothes at least for a few minutes and smells good.
Green tea (jasmine if you like it like that) has anti-inflammatory properties and can help to drink it as well as to put the cooled wet teabags on your eyes (mild astringent too). Witch hazel on eyes is also helpful. Alkalizing diet in general to reduce body's inflammatory response; drink plenty of filtered water. Reduce exposure to toxic chemicals in household cleansers, personal care products, any food or foodlike substance that isn't made from scratch, etc.
I have recently started making my own bad-chemical-free household cleansers and using no-bad-chemical shampoo, etc., and can really see a difference. Especially the cleaners, and mine smell so good! Before, I had been using "green" commercial cleaners. Till I started finding out what they don't put on the labels, and the green ink on the label doesn't mean it's as "green" a product as they want you to think.
Hop, they say to think of your allergies like a bucket of water. You can fill a bucket all the way to the top with water (allergens like pollen or allergic foods or irritants like chemicals), and the bucket will not overflow (no symptoms yet). But at some point, when you keep adding one more drop and one more drop, eventually the bucket will overflow (you will have symptoms).
That's why reducing the load of all irritants, toxins, allergens and likely allergens is recommended even though it seems like it's just the pine pollen that's bothering you.
