Explosion of allergies: pollution to blame

By 2050, 50% of the population will be allergic... !

It's spring! And like every year, it's a nightmare for millions of French people... Today, according to the ANSES (National Agency for Environmental and Occupational Health Safety), 1 in 3 French people is affected by respiratory allergy. And this is 10 times more than 50 years ago!

Bad news: allergy symptoms are aggravated by air pollution, fine particles and gases.

Allergy: a not so well known pathology .

The winter colds are finally gone... but no respite for you unfortunately!

Now it's time for spring allergies to return... Runny nose, itchy eyes, the itchy throat, the incessant sneezing: It may look like a cold, but it's actually symptoms of a respiratory allergy, often called hay fever

Although allergies are one of the most widespread pathologies, they remain "under-diagnosed today", according to the French Allergists' Union (SYFAL). In France, there is a deplorable lack of allergists. Only 1,200 doctors are trained. Thus, 45% of allergy sufferers are not diagnosed !

Two types of respiratory allergies

There are two types of allergies : those that last all year (persistent allergies) and those that only occur in spring (seasonal allergy).

A respiratory allergy is an allergic inflammation of the nasal cavity nasal cavity due to sensitisation and overreaction to an allergen such as pollen.
Thus, The return of spring causes the flowering and thus the diffusion of these pollens in the air. of these pollens into the air. A respiratory allergy causes tingling of the nose and eyes, sneezing, reduced sense of smell, but also fatigue, coughing attacks and asthma in sensitive individuals

The word of the expert ...

Naturopathy provides many answers to allergies in adults and children. It is important to avoid exposure to allergens: for example, carpets, which are real dust mite nests, should be avoided. The same goes for housework: choose a hoover with a HEPA filter, otherwise the dust is re-suspended and irritates your airways.

Asthmatics and allergy sufferers know that coughing attacks occur most often at night, and sleep can be affected. That's why you have to make more effort in the bedroom. I myself am allergic and I have noticed that I have noticed that by putting a TEQOYA ioniser in my bedroom I sleep better, I don't have coughs at night.

Our living environment is to blame

Evocation de la chaleur

The causes of respiratory allergies are mostly genetic. Their increase is closely linked to our urban environment our urban living environment, where our immune defences are weakened for a variety of reasons reasons. Small, insulated and air-conditioned flats promote proliferation of dust mites.

In addition to dust mites, there is also the hair from our pets, which also triggers allergies. Faced with allergens, our immune system does not always know how to adapt. The presence of bacteria, which have been part of our environment for hundreds of millions of years, can trigger allergies. years, can trigger abnormal, inappropriate and excessive reactions from the body The frequent use of antibiotics does not help!

Finally, outdoor air pollution (fine particles, diesel emissions) and indoor air pollution (tobacco, formaldehyde, heavy metals, VOCs, etc.) are factors that aggravate and promote the symptoms. Staying at home is not the solution! Outdoor pollutants enter our homes through the ventilation system and by infiltration (windows, doors, chimneys, etc.) and add to the indoor pollutants.

Once indoors, pollens can retain their allergenic capacity for up to a year!

Why does pollution make allergies worse?

An increase of 2 to 7% in emergency room visits for asthma attacks has been measured when moving from low to high pollution levels. Allergens, pollens in particular, have a complex relationship with air pollutants. pollutants.

First of all, pollutants increase the toxicity of pollen :

  • Particles (Ozone, SO2 or NO2) fracture pollens and make them emit allergens
  • Certain gaseous pollutants (NO2), as well as water, cause pollens to emit harmful particles
  • Pollutants are deposited on pollens during their "journey" through the air and make them more aggressive

In addition, the fine particles breathed in irritate the respiratory and ocular mucous membranes, making the airways more receptive and facilitating the accessibility of pollens to the body. The fine particles inhaled irritate the respiratory and ocular mucous membranes, making the airways more receptive and facilitating the accessibility of pollens in the body. The sensitivity of individuals to pollen is thus increased during pollution peaks. This is why even in cities where there is little greenery the urban population is sensitive to allergies.

Fine particles, diesel and road traffic: PM2.5 levels above 20 μg/cm3 on average over the year - corresponding to European standards, i.e. twice the thresholds recommended by the WHO - or levels of 30 μg/cm3 for PM0.1 increase the occurrence of bronchitis symptoms and impaired lung function in children. The heavier the traffic, the more children (aged 4 months to 4 years) are hospitalised for obstructive bronchitis. This continues with age. And it has been shown that diesel emissions can cause an allergic reaction in people with no genetic predisposition.

Pregnancy and allergies: an update ...

Many women with allergies experience changes in their allergy symptoms during pregnancy. For some, they decrease. For others, they become much worse. According to Dr. Nhân Pham-Ti, hormones are often responsible for this for this change. Pregnancy can also lead to asthma. The mother must then protect herself from all the aggravating factors, the most important of which is pollution. Poorly controlled asthma can have very harmful consequences for the mother (blood pressure, anaemia, risk of miscarriage) and the foetus (delayed growth, prematurity, low birth weight, malformations).

How to fight against respiratory allergies?

  • Monitor pollution and pollen peaks on the National Aerobiological Monitoring Network (RNSA) website - new work is underway to provide ever more accurate alerts, particularly for forecasts
  • Avoid physical exertion and sport in the event of a pollution or pollen peak
  • Air out briefly in the morning and late evening, and leave windows closed the rest of the day
  • Dry your laundry indoors rather than outside as pollen can cling to it
  • Get diagnosed to identify which pollens you are sensitive to
  • Change your clothes and wash your hair more often, pollens cling to fibres and clothes
  • Finally, don't neglect taking antihistamine medication
