The climate crisis and global warming are causing enormous damage to the planet such as floods, floods and huge fires.

But that's not all.

According to new research, the climate crisis may affect many of us on a personal level as well and exacerbate allergy attacks.

Since the beginning of the Industrial Revolution, scientists have been measuring an increasing increase in CO2 in the atmosphere, with two-thirds of this increase occurring in the last 50 years.

Along with CO2, greenhouse gases are also emitted into the atmosphere that contribute to global warming and prevent it from cooling down.

These alarming processes cause changes and great volatility in the change of seasons and weather, and as a result also in the aggravation of our allergies.

Due to these ecological changes, many plants have to adapt to different temperatures, so they change their seasonal behavior.

This means that the rash season begins several weeks earlier, so seasonal allergy symptoms, such as allergic rhinitis, also appear earlier than usual.

Studies from recent years suggest that the duration of the pollination season of plants - the most critical period for allergic people - has lengthened following the climate crisis.

Further studies have even shown that the amounts of pollen grains distributed by the plants have increased significantly, causing aggravation of allergy symptoms among many.

People who suffer from rash powder suffer for a longer period of time from seasonal allergic rhinitis (also called "hay fever") and their allergy symptoms have significantly worsened.

It is not only the flowers that make the allergies worse. Industrial plants emit particles that carry long distances into the air, causing irritation in the airways. Those particles significantly increase the incidence of allergy and exacerbate the symptoms. In recent years we have witnessed a steady and continuous increase in the rate of people suffering from chronic allergic rhinitis and asthma as a result. The irritation of the mucous membranes by those contaminating particles causes allergic rhinitis even without the previous and clear presence of a tendency to allergy.

The many fires, such as the one that occurred only a few weeks ago in the Jerusalem mountains, and in recent years on all continents, also aggravate the allergy symptoms and increase its prevalence. In a fire, many pollutants are released into the air and they are carried far and wide. Inhalation of these substances irritates the airways and leads to asthma and chronic rhinitis several times more severe than that caused by pollutants emitted by polluting vehicles using diesel engines.

The fall season that is starting soon is a challenging season for people suffering from allergies.

The typical bloom of autumn brings with it many challenges for those sensitive to inhaled allergens, and the first rains are saturated with polluting particles that have sunk on the roofs of buildings and roads during the summer season.

The climate crisis causes autumn to lengthen and the flowering and pollinating plants during this period to change their behavior and thus also affect the severity of allergy symptoms.

What happens to the body during an allergy attack?

Allergy is one of the most common medical problems in the world. The body attacks an innocent substance (allergen), which seems to him (for no reason) to be threatening. The immune system mobilizes forces and attacks a false attack that manifests itself in allergy symptoms that can manifest in various diseases depending on the type of allergen (for example: powdered grain, dust, food like milk or peanuts, medicine like penicillin or bee sting). Allergy symptoms can include runny nose, nasal congestion, difficulty breathing, skin rash and more. In some cases an allergy can also be life-threatening, such as a food allergy or a bee sting, and should be treated seriously.

There are three main approaches to treatment: The first and most effective is avoidance. Since this is a reaction to an external substance, the doctors advise and recommend that you avoid the cause of the allergy as much as possible. At the same time, keep in mind that this is not always possible, certainly when there are substances that are carried in the air and reach everywhere like dust or plants.

The treatment has greatly improved in recent years.

The second approach is pharmacotherapy.

The treatment addresses the symptoms caused by the allergy.

The treatments with anti-allergy tablets have undergone a revolution in recent years and the side effects that were common in the use of these pills have largely disappeared.

Today there are treatments like antihistamines that work around the clock and do not cause a feeling of drowsiness.

In some cases, anti-inflammatory treatment of the nasal mucosa can be given using a spray or preparations containing a small amount of steroids or antihistamines given directly to the nasal mucosa in cases of allergic rhinitis.

The third approach - vaccines.

Immunotherapy is an approach in which the immune system is exposed to the allergen gradually and with close medical supervision in order to give the body an opportunity to develop an immune response, which reduces the expression of the allergy and improves the malfunction caused by the allergy.

This is a treatment that lasts between three and five years and is done in allergy clinics.
