In anthroposophy, the eruptive illnesses of the first seven years are the body discharging excess while soul-spiritual forces rebuild it from the head.
Childhood Illnesses in Anthroposophy is Rudolf Steiner's account of why the first seven years are the most illness-prone phase of human life. In his lecture of 24 October 1922 (From Comets to Cocaine, GA 348), Steiner taught that invisible soul-spiritual forces, working from the head like a sculptor, rebuild the inherited body member by member. When a child takes in too little nourishment, these forces find no material to shape and fidget aimlessly, producing convulsions and diarrhoea. When a child takes in too much, the surplus is driven out through the skin as measles and scarlet fever, or through the lungs as diphtheria and pneumonia. The eruptive childhood diseases are thus reframed as the body discharging excess during its hardest constructive labour. Steiner held that this danger eases once the second teeth arrive, making the school years from seven to fourteen the healthiest period of life.
Childhood illnesses, in Steiner's medical teaching, are the visible signs of an enormous hidden labour. During the first seven years the head directs the rebuilding of the whole inherited body. Measles, scarlet fever, diphtheria and the infant convulsions are not random misfortunes but the by-products of that work, the surplus or deficit the forming forces must somehow resolve.
In Steiner's Own Words
Now, if too much food is absorbed by the system, the head cannot keep up; it cannot handle too large an amount and will try to eliminate the surplus. The food has already been absorbed into the blood through the intestines, however, so the head cannot eliminate the surplus in the normal way. What does it do then? It discharges the superfluous substances through the skin. Measles and scarlet fever are the result. When too much food is absorbed, however, it must somehow be eliminated, occasionally even through the lungs. Diphtheria and pneumonia are the body's defence measures used to rid itself of substances it cannot otherwise eliminate through the skin.
What it Means Today
Steiner's claim that childhood illnesses do developmental work, rather than simply harm, can be tested against modern epidemiology. In The Lancet of 1 May 1999, Johan Alm and colleagues published "Atopy in children of families with an anthroposophic lifestyle," reporting that pupils at Swedish Steiner schools carried a significantly lower risk of allergy than children in ordinary schools. The larger PARSIFAL study, led by Helen Floistrup and published in the Journal of Allergy and Clinical Immunology in 2006, followed 6,630 children across five European countries and traced the protective pattern to specific habits of anthroposophic families: restrained use of antibiotics and fever-suppressing medicines, and letting the eruptive illnesses of early childhood run their course. The same dataset found that a measles infection was associated with a lower rate of IgE-mediated eczema. Researchers read this through the hygiene hypothesis and immune maturation; anthroposophic pediatricians, working in the lineage of Ita Wegman's clinical school, read it as confirmation that the fever and the rash are the body completing a task. Thalira synthesis: Steiner did not promise that childhood illness is harmless, he proposed that the eruption is the seven-year sculptor expelling what it cannot build with, which is why suppressing the sign without honouring the work it performs is, in his frame, the deeper error.
