Tree Pollen Skyrockets: Allergy Season Hits "Very High"

Tree pollen levels have unexpectedly soared to "very high" as warmer and drier conditions emerged after prolonged rainfall. This shift has caused a rapid increase in airborne pollen, with alder pollen expected to be high on dry days, alongside hazel, poplar, cypress, and elm. The tree pollen season, which lasts until mid-May, significantly affects allergy sufferers.

Consultant allergists are anticipating a "bumper pollen season" and recommend that individuals prepare by obtaining necessary antihistamine medication. The preceding rainy weather has invigorated trees, and the subsequent drying has led to the release of pollen. This phenomenon occurs as temperatures in some parts of the UK have recently exceeded those in cities like Athens and Barcelona.

Experts note that spring tree pollen is influenced by the previous summer's weather, suggesting that continued mild conditions could lead to stronger grass and weed pollen later in the summer. Data since 2006 indicates a year-on-year increase in pollen levels, with potential causes including climate change, pollution, and increased planting of birch trees in suburban areas.

While countryside pollen counts may be higher, city dwellers often experience worse symptoms. This is partly attributed to air pollution particles carrying pollen deeper into airways. Allergy UK advises limiting outdoor activities on high pollen days, wearing sunglasses, and changing clothes post-exposure, with the NHS recommending antihistamines or steroid nasal sprays for treatment.
