Spring Allergies

Spring is the time of year for seasonal allergies. As the trees start to bloom and the pollen is released into the atmosphere, allergy sufferers begin their annual ritual of sniffling and sneezing. The biggest spring allergy trigger is pollen -- tiny grains released into the air by trees, grasses, and weeds for the purpose of fertilizing other plants. When pollen grains get into the nose of someone who’s allergic, they send the immune system into overdrive. The immune system, mistakenly seeing the pollen as foreign invaders, releases antibodies -- substances that normally identify and attack bacteria, viruses, and other illness-causing organisms. The antibodies attack the allergens, which leads to the release of chemicals called histamines into the blood. Histamines trigger the runny nose, itchy eyes, and other symptoms of allergies. Pollen can travel for miles, spreading a path of misery for allergy sufferers along the way.
 The higher the pollen count, the greater the misery.
 Here are some of the biggest spring allergy offenders.
