– The immune system of small children does not mature in the same way as before. They are more protected, do not play so much outside and come into contact with animals and plants the same way as before, says Åslög Dahl.

These bacteria are important because they help the immune system to develop tolerance to natural substances in our environment, such as pollen or fungal spores.
– These substances are not really dangerous, but the body has to learn not to react to them.
Between 20 and 25 percent of the population is vulnerable to pollen, and although hereditary factors also play a role, environmental factors strongly contribute. One of them is global warming, which in part means that plants produce more pollen, but also means that we can bring new plant species that could not have lived here before.

Pollen allergy usually occurs in childhood but can be affected at any time of life. If you have succeeded in the Middle Ages, there is a great chance that you can survive the rest of your life.
