Stress and "nerves" are physiological phenomena, in particular, manifesting themselves at the endocrine level, that is, they are accompanied by the production of hormones. Hormones are distributed throughout the body and affect a wide variety of organ groups. Therefore, the occurrence of diseases under stress and strong feelings is not magic, but a completely understandable physiological fact.

For example, prolonged monotonous stress is one of the factors in the development of hypertension. With it, norepinephrine is released in large quantities (this is a neurotransmitter, not a hormone, but in this case it is not so important), which has nowhere to go, so it spasms the microvessels, which increases pressure. Over time, the effect becomes permanent. Hypertension acts as a risk factor for heart attack, so it turns out that stress leads to heart attack.
