Which trees cause the worst seasonal allergies?
Almost any tree is capable of inducing allergic reaction if you're programmed that way. In different parts of the country, people will react to different trees depending on what's there. For example, on the east coast, it is very common to be allergic to birch, oak and maple tree pollen. If you go to the western states, you may find that the cottonwood, poplar, and aspen trees are much more of a problem.
And of course the area where you live will determine when you have a problem. It takes from around February to the end of May for the tree pollen season to work its way up from Florida up through Maine. Allergy sufferers should be careful not to plan trips that take them in the direction of the tree pollen.
How long is the season in the Northeast?
The Northeast is particularly afflicted by tree pollen. There is so much of it that the average person is familiar with the sight of cars covered with yellow pollen during late April and early May.
Also when an allergic person will suffer depends on which tree they're allergic to. Some of them will pollinate in mid-April, and others will not pollinate until later, toward the end of May approaching Memorial Day.
Some very unlucky people that are sensitive to all these different tree pollens may have a tree pollen season in the Northeast that goes for 6 weeks. Others, if they're only sensitive to one type of pollen, might have symptoms only for 3 weeks during that time.
Do all season allergies- grass, ragweed, tree pollen- affect people the same way?
The symptoms one gets from tree pollen allergy are exactly the same as grass, ragweed, even symptoms from dust mite or cat allergy. You breathe the allergy substance in and an allergic reaction ensues, giving you the stuffy nose, sneezing, itchy eyes and so on.
