Ragweed
Ragweed is a plant that belongs to the Asteraceae family. It is found in many parts of the world, including North America, Europe, and Asia. Ragweed is a common cause of allergies. The pollen from ragweed plants can cause hay fever, asthma, and other respiratory problems in people who are allergic to it.
Ragweed pollen is very tiny and light. It can be carried by the wind for long distances. Ragweed pollen can cause allergies even if you are not near a ragweed plant. Ragweed pollen is most common in the fall, but it can be found in the air all year round in some parts of the United States.
If you are allergic to ragweed, you may have symptoms such as a runny nose, sneezing, itchy eyes, and a sore throat. You may also have trouble breathing. Ragweed allergies can make asthma worse. If you have ragweed allergies, you should try to avoid exposure to ragweed pollen.
There are a few things you can do to help reduce your exposure to ragweed pollen and ease your allergy symptoms. First, try to stay indoors as much as possible when ragweed pollen is high in the air. You can also wear a dust mask or a respirator when you're outside. If you have to be outside, try to do so in the morning, when pollen levels are typically lower. And be sure to shower and change your clothes after you've been outside to remove any pollen that may be clinging to your hair or clothing.
If you're still struggling with your ragweed allergies, talk to your doctor about other treatment options, such as allergy shots or medication.
