Spring isn't the only time for allergies to annoy you, however. Many people who suffer from seasonal allergies feel fine in the spring but can be affected during the summer, fall and winter. And for some, it's a year-round annoyance.

Plants releasing pollen in the spring can turn a beautiful day outdoors into a nightmare.
And with warmer temperatures reported across the country over the past several weeks, it appears allergy season came early.
"We're seeing activity way ahead of schedule across the southern states. And now we're starting to get reports for very early activity all up the eastern side of the U.S. too," Theresa Crimmins, director of the USA National Phenology Network (USA NPN), told FOX Weather. "All the way up into even New York, Massachusetts and Maine."
Pollen is problematic

The biggest spring allergy trigger is pollen. During the spring and summer, trees, grass and weeds release pollen into the air to fertilize other plants. But when that happens, and someone has allergies, symptoms such as sneezing, itching, congestion and a sore throat can occur.
Cooler air and rainy weather help keep pollen counts low," said Dr. John Whyte, chief medical officer at WebMD. "It’s the dry, windy days that really cause challenges."
The wind will blow the pollen through the air, and if it lands in your eyes, nose or lungs, it can trigger allergy symptoms.
Trees, grass and weeds – oh my!

Trees that can have the most significant effect on an allergy sufferer include alder, ash, aspen, beech, box elder, cedar, cottonwood, cypress, elm, hickory, juniper, maple, mulberry oak, olive, palm, pine, poplar, sycamore and willow.
But it's not only trees that can have an effect. Grasses and weeds that can trigger allergies, according to WebMD, include Bermuda, fescue, Johnson, June, orchard, perennial rye, redtop, saltgrass, sweet vernal and timothy.
Allergies also aren't only necessarily triggered by pollen. When it rains in the spring, mold can form, making you feel under the weather. And when spring cleaning takes over your home, dust mites could be stirred up, leading to allergy symptoms.
