Why is the number of allergic people increasing?
Over the past few decades, the number of allergic people as well as allergens has increased rapidly. New chemicals, medicines and products are emerging that are provoking various immune reactions in the body. Among newborns, about 20-30% of children have food allergies, says Dr. Denis Slinkin.
Exactly 30 years ago the theory of the influence of hygiene was put forward. Dr. Denis Slinkin argues that increased attention to hygiene has weakened human immunity, sharpened from nature to contact with many antigens.
Children from civilized countries do not get enough load of the immune system at an early age, and over the years they develop hypersensitivity to many substances. This theory is supported by the fact that offspring of large families are much less likely to suffer from rhinitis and eczema than the only offspring in families. In third world countries, where hygiene is still low, allergies are much less. Long-term observations of emigrants have shown that as people move to developed countries, as well as with increasing wealth, they have more immune disorders.
Dr. Denis Slinkin names other triggering factors for allergies. These are the Caesarean section, taking antibiotics in the first year of life, the use of antibacterial cleansers, increased consumption of chemical products, stress, environmental degradation.
