If you live in Central Texas, you're all too familiar with the term Cedar Fever. For those not familiar with the term, Cedar Fever is the Texas version of hay fever -- except that a tree pollinating in the winter causes the symptoms. Mountain cedar, or Juniperus ashei, is unusual in that the tree pollinates in the wintertime, typically when no other significant pollens are present in the air. Mountain cedar trees release enormous amounts of pollen into the air, and people living in areas such as Austin, San Antonio or Dallas may experience severe symptoms of allergic rhinitis and asthma during the winter months as a result.

Other parts of the country have other species of Juniper trees, such as Arizona Cypress in Northern Arizona, and Western Juniper here along the Northern California coastline. Most of these Juniper trees cross-react, meaning that if you're allergic to one type of Juniper tree, you're likely allergic to all of them. So, if you're planning on a trip to Central Texas this winter, and you suffer from seasonal allergies, don't forget to pack your box of Kleenex. You never know when Cedar Fever might strike!

Other Causes of Winter Allergies
Think that allergies aren't a problem during the winter? Think again. Some areas of the country experience their worst allergy season during the wintertime, when mountain cedar pollinates. And even when the plants outside aren't pollinating, other triggers still exist to make your nose congested and runny. From indoor Christmas trees to outdoor mold and irritants such as cold and windy weather, there are a number of non-pollen sources of wintertime nasal symptoms. In addition, cold temperatures can lead to hives, which is called cold urticaria.

All About Hay Fever
Hay fever, or allergic rhinitis, is the most common chronic disease, affecting up to 30 percent of the population. It is the most common reason for chronic sinus and nasal problems. Children and young adults are the most common age groups affected by hay fever, although many older adults and elderly people also experience symptoms.
