Plane Trees: Allergies and Symptoms
Plane trees are tall and majestic, with spreading branches and attractive green bark. They’re often found in cities, lining streets and parks. But did you know that plane trees can also cause allergies?
Plane Tree Allergies
Many people report having an allergy to plane trees, especially the London plane tree. Symptoms of a plane tree allergy can include:
- Itchy eyes
- Sneezing
- Coughing
- Runny nose
What Causes Plane Tree Allergies?
It’s commonly assumed that plane tree pollen causes these allergies. However, research suggests that the real culprit may be tiny hairs called trichomes. Trichomes cover the young leaves of plane trees in spring and are released into the air as the leaves mature.
Trichomes and Allergies
Trichomes are very fine and spiky, and they can irritate the nose and throat when inhaled. This irritation can trigger allergy symptoms. In fact, a study conducted in Sydney, Australia found that while 86% of people tested were allergic to something, only 25% were allergic to plane trees. And all those who tested positive for an allergy to London plane trees were also allergic to grass.
Distinguishing Between Plane Tree Pollen and Trichome Allergies
If you’re allergic to plane trees, it can be difficult to tell whether your symptoms are caused by pollen or trichomes. Here are a few key differences:
- Pollen season: Plane tree pollen season typically lasts for about six weeks. Trichome season, on the other hand, can last for up to 12 weeks.
- Symptoms: Pollen allergies tend to cause more severe symptoms than trichoe allergies. Pollen allergy symptoms can include watery eyes, a runny nose, and sneezing. Trichoe allergy symptoms are more likely to be limited to itching and irritation of the nose and throat.
Managing Plane Tree Allergies
If you’re allergic to plane trees, there are a few things you can do to manage your symptoms:
- Avoid exposure: The best way to avoid plane tree allergies is to avoid exposure to the trees. If you know that you’re going to be spending time in an area with plane trees, take precautions such as wearing a mask or taking an antihistamine.
- Medications: Antihistamines can help to relieve allergy symptoms. They work by blocking the histamines that are released by the body when it comes into contact with an allergen.
- Nasal sprays: Nasal sprays can also help to relieve allergy symptoms. They work by reducing inflammation in the nasal passages.
Conclusion
Plane tree allergies can be a nuisance, but they can be managed with proper care. By understanding the causes of your allergies and taking steps to avoid exposure, you can enjoy the beauty of plane trees without suffering from allergy symptoms.
