Pollen Allergies in France: Why More People Are Affected and What to Do

As spring approaches, a significant portion of the French population is bracing for allergy season. Almost all of France is currently on pollen alert, with only the southwest region currently spared. But is it simply hay fever, or is there cause for greater concern? Understanding the types of pollen, symptoms, and available treatments is crucial for navigating this increasingly common health challenge.

Understanding Pollen Allergies

Pollen grains, while essential for plant reproduction, can trigger allergic reactions in sensitive individuals. These reactions occur when the immune system mistakenly identifies pollen as a threat, releasing histamine and other chemicals that cause allergy symptoms. Pollen is generally considered to be relatively large particles, meaning it typically affects the upper respiratory tract – the ears, nose, and throat.

When is Pollen Season in France?

The allergy season in France is becoming increasingly prolonged, extending from February to August. The first warnings of the year were issued on February 15th due to high levels of Cypress and Alder pollen, particularly from the Mediterranean to the Channel coast.

Month-by-Month Breakdown:

• February – April: Cypress, Alder, Poplar, Ash, Birch, Hornbeam, and Plane trees are primary concerns.
• May – August: Grass pollen becomes dominant.

Symptoms of Pollen Allergies

Common allergy symptoms include:

• Runny nose
• Coughing
• Red and watery eyes
• Breathing difficulties (in severe cases)
• Asthma attacks (in severe cases)

Allergic Asthma: A Serious Concern

In some individuals, particularly those with sensitivities or exposure to finer pollens, allergens can travel deeper into the respiratory system, reaching the bronchi. This can trigger allergic asthma, causing the bronchi to tighten, leading to wheezing and difficulty breathing.

Managing Pollen Allergies: Practical Steps

The Réseau National de Surveillance Aérobiologique (RNSA) recommends several strategies to minimize exposure and manage symptoms:

• Antihistamines: Consider antihistamine-based treatments.
• Hygiene: Wash clothes regularly and rinse hair in the evening.
• Ventilation: Air rooms early in the morning or late in the evening when pollen levels are lower.
• Indoor Practices: Dry clothes indoors and keep car windows closed.
• Awareness: Check pollen levels on the RNSA website before going outdoors.

Current Pollen Levels in Île-de-France (Paris)

As of today, February 25, 2026, pollen levels in the Invalides area of Paris (7th arrondissement) are as follows:

• Tree Pollen: Moderate
• Grass Pollen: None
• Ragweed Pollen: None

Looking Ahead: Climate Change and Pollen

Research suggests that climate change is exacerbating pollen allergies in Europe. Studies indicate that airborne pollen seasons are starting earlier and lasting longer, particularly in France and northwest Italy.

By staying informed, taking preventative measures, and seeking appropriate medical advice, individuals can effectively manage pollen allergies and enjoy a better quality of life during allergy season.
