What are the 'Chicago Seven' in psychosomatics?

The 'Chicago Seven' refers to a group of diseases that are known to have a strong association with psychological disorders and stress. These include conditions like ulcers, asthma, and non-specific ulcerative colitis. The host notes that while there is a clear correlation between these diseases and emotional states, asserting a direct cause-and-effect relationship, such as claiming that a specific emotional trauma leads to a specific illness, is more speculative and often veers into the realm of esotericism.
