Moscow's early birch pollen season triggers stronger allergy symptoms

Moscow's pollen season has arrived earlier than usual this year. An unusually warm spring has brought birch pollen—one of the most aggressive allergens—into the air ahead of schedule. Residents with allergies are already experiencing stronger symptoms as the peak season approaches.

Over the past five years, studies by the Russian Hydrometeorological Service show a clear shift in birch pollen timing. The season now starts 10 to 15 days sooner, often in late March or early April instead of mid-April. It also lasts longer—up to four weeks compared to the previous average of two to three weeks in the 1990s and 2000s. Warmer spring temperatures are the main cause of this change.

Doctors recommend that allergy sufferers take precautions as the peak of birch pollen is expected by late April. Starting antihistamines after consulting a specialist can help manage symptoms. Using air humidifiers indoors also reduces pollen levels in living spaces. To limit exposure, residents are advised to wear protective masks when outside. Avoiding long walks on dry, windy days can further cut down on pollen inhalation. Some may also need to temporarily avoid foods that trigger cross-allergic reactions, such as apples, carrots, or nuts.

The early and prolonged birch pollen season is already affecting allergy sufferers in Moscow. With the peak still to come, following medical advice and reducing outdoor exposure will be key. Simple steps like masks, humidifiers, and dietary adjustments can help ease symptoms during this period.
