It’s nothing to sniff at: Climate change has extended pollen seasons by three weeks and is stimulating plants to produce 20% more pollen.

That means around 25% of U.S. adults are headed into spring with an increased load of sniffles, itchy eyes, sneezes, and wheezes (not to mention associated sleep problems and mood changes).

But you can do a lot to ease your discomfort. At home, keep windows closed, use a HEPA air filter, and wash or rinse your clothes, take a shower, and wash your hair after spending time outdoors. And change your pillowcases and sheets frequently.

You also want to work with your doctor to find an allergy medication that's safe and effective.

If you have high blood pressure, diabetes, heart disease, an enlarged prostate, or glaucoma, try a non-drowsy antihistamine. And ask your healthcare provider if you can use corticosteroid or cromolyn sodium nasal sprays to ease symptoms.

When you're outdoors, make sure you have taken your allergy meds.

In addition, I wear a mask and sunglasses to help keep pollen away. It seems to help; you might try it too.

Lifestyle choices can also help combat pollen allergies. Focus on eating nutrient-dense foods, including fruits, veggies, lean proteins, and whole grains with anti-inflammatory flavonoids and vitamin C, as well as foods such as salmon that are packed with anti-inflammatory omega-3 fatty acids.
