Why are allergies on the rise? The invisible causes of a new epidemic

A silent disease affecting more and more people

Suddenly you start sneezing, your eyes itch, your nose closes. They tell you it’s “just an allergy,” but behind this word lies one of the most underestimated health challenges of our time. Today more than 20 million Italians are living with an allergy – and the number is growing every year. The World Health Organization estimates that by 2050 half the world’s population will be allergic to something.

It’s not just a feeling: allergies are really increasing. In form, frequency and severity. But why? And what is behind this silent explosion that is changing the way we live, eat and breathe?

A modern epidemic: the numbers speak for themselves

In Italy, 30-35% of the population suffers from at least one form of allergy. Among children under 14, the percentage rises to nearly 40%. In the 1970s, allergies were considered relatively rare. Today they are the norm. The increase concerns not only the quantity but also the variety of allergic manifestations: new food allergies, cross-reactions, and increasingly common contact dermatitis.

A curious fact? In some highly polluted urban areas, cases of allergic asthma in children are four times higher than in rural areas. We are facing a real environmental epidemic, silent but very real.

What is really an allergy?

Simply put, an allergy is an exaggerated reaction of the immune system to a harmless substance-a pollen, a food protein, a metal, a drug. Our body, for some reason, interprets it as a threat and triggers a defensive response that harms us, however.

Warning: this should not be confused with an intolerance (such as to lactose), which is a digestive problem and does not involve the immune system. Allergy, on the other hand, can trigger even severe symptoms: asthma, hives, breathing difficulties, up to anaphylactic shock.

Why does the immune system go crazy?
It evolved to fight real viruses and bacteria. But today, in an environment that is too clean and devoid of natural stimuli, it finds no real enemies and overreacts to harmless substances. It is an “aiming error” of our body, disoriented by a world that has changed too quickly.

Why are allergies increasing? The real causes

1. Urban pollution and fine particulate matter
We breathe air laden with fine particulate matter, heavy metals and chemicals. This irritates the respiratory mucous membranes and makes them more sensitive to allergens. Some pollutants also change the structure of pollens, making them more aggressive.

2. Climate change
The seasons have changed. Plants bloom earlier, pollens circulate longer and spread to new areas. Such is the case withragweed, an invasive plant that causes allergies in half of Europe.

Is it true that climate change makes allergies worse?
Yes. Higher temperatures, less rainfall and longer seasons increase the concentration of allergens in the air.

3. The hygiene theory
Today’s children grow up in ultra-clean environments, with no contact with nature. According to this theory, the absence of good germs prevents the immune system from learning to distinguish true dangers from false ones, increasing the risk of allergies.

4. Modern Diet and the Gut Microbiota
Our gut is home to the microbiota, an ecosystem critical for immune balance. A diet high in sugars, preservatives and processed foods damages it, promoting inflammation and allergies.

5. Genetic and lifestyle factors
If one of the parents is allergic, the risk increases. But the environment can also “activate” these predispositions: stress, urbanization, little time outdoors, and drug abuse during childhood.

The most common allergies today

The increase also affects the variety of allergies. Here are the main ones:

1. Respiratory allergies
The most common ones, related to:

• Pollen (grasses, parietaria, olive, birch)
• Dust mites
• Molds and spores
• Animal hair

Symptoms: rhinitis, asthma, cough, chronic fatigue.

2. Food allergies
Increasingly common, especially among children. The foods most at risk:

• Cow’s milk, eggs, nuts, soy, tarts, wheat, nickel (tomatoes, cocoa, legumes…)

Why does my child already have an allergy at age 4?
Today’s children are exposed to risk factors early on. If the parents are also allergic, the risk increases. Early diagnosis is needed.

3. Contact allergies
They occur through contact with irritants. The most common:

• Nickel (jewelry, buttons)
• Latex, perfumes, cosmetics, detergents

Symptoms: dermatitis, itching, redness, blisters.

How to defend yourself and live with allergies

1. Reduce exposure to allergens

• At home: remove carpets, heavy drapes, use HEPA filter, mite-proof mattress covers.
• Outdoors: avoid parks during pollen periods, shower upon return.
• Use an air purifier, especially in the bedroom.

2. Take care of nutrition
Diet rich in fiber and fresh foods, low in industrial foods. A healthy microbiota is a natural ally.

3. Early diagnosis
Useful tests:

• Prick test
• Specific IgE assay
• Controlled exposure testing (medical only)

4. Treatments and immunotherapy

• Antihistamines, nasal sprays, eye drops
• Specific immunotherapy (the “vaccine” against allergy)

Can allergies go away?
Some in children (e.g., milk, eggs) regress. Others remain but are managed well with the right strategies.

Mite-proof mattress covers: the first barrier against nighttime allergies

Many allergy sufferers do not know it, but the bed is one of the places with the highest concentration of dust mites, responsible for rhinitis, asthma and difficult awakenings. Mites lurk in the mattress, pillows and bedding, and feed on dead skin cells.
The simplest and most immediate solution is to use mite-proof mattress covers and pillowcases, which are made of tightly woven materials that prevent allergens from coming into contact with the respiratory tract. They are breathable, washable at high temperatures and often certified against household allergens.
A simple gesture that can improve the quality of sleep-and life.
