This year 2023 is being "the worst year so far this century", because exaggerated pollination, a breeding ground for allergies, is a consequence of the lack of rain and the increase in temperatures. In Spain between 20 and 25% of the population is allergic.

The "unstoppable" growth of the disease is influenced by many factors, not only genetic predisposition, but also pollution and the environment, the fact that children spend more time inside homes and have few siblings. In this situation, what should be done is not to trivialize the disease and have a diagnosis as soon as possible.
