## What do our nerves have to do with it? The nervous system is connected to all human organs and systems, so any disturbances in its operation affect the function of the entire body. Negative experiences can affect the general well-being, and a strong shock can provoke a heart attack or [stroke](https://ul.orna.me/KOge/librarydisease?id=184). However, it is unlikely to be the only cause. Our nature enables us to cope with both short-term shocks and prolonged stress. Shocks and chronic [stress](https://ul.orna.me/KOge/librarydisease?id=19) become dangerous if there is a simultaneous encounter with an infection or there is a genetic predisposition to some disease. In such cases, stress strikes at the weak points. There is a common belief that prolonged stress can cause cancer. However, ===there is no proof of this. Rather, it is the way of life in a difficult situation and the excesses in which many people indulge that can cause health issues. These include overeating, excessive consumption of alcohol, smoking, and disruptive sleep patterns that may lead to an unhealthy lifestyle and subsequently, [cancer](https://ul.orna.me/KOge/librarydisease?id=39). ## Psychosomatics to blame Our negative emotions stimulate the sympathetic nervous system — and as a result blood pressure and temperature rise, the pulse quickens, vessels spasm, the mouth becomes dry, there is an urge to pee, and there are feelings of itching, nausea, weakness, etc. There are several diseases caused by disorders of the nervous system that are psychosomatic. The diagnosis "psychosomatic" is made if the patient has been repeatedly examined and the causes of the disease have not been identified. In this case, it is recommended to visit a neurologist. Psychosomatic issues can be caused by [hypertension](https://ul.orna.me/KOge/librarydisease?id=173), bronchial [asthma](https://ul.orna.me/KOge/librarydisease?id=177), eczema, hyperthermia, irritable bowel syndrome, [obesity](https://ul.orna.me/KOge/librarydisease?id=167) or excessive weight loss, and more. These are the diseases that sometimes (but by no means always) arise because of nervous breakdowns. ## What is primary and what is secondary? You can not separate the body and the psyche. Mental stress can cause physical ailments, but the disease of any organ or system can also cause an emotional disorder. For example, irritability, apathy, and depression are often the result of [thyroid](https://ul.orna.me/KOge/librarydisease?id=44) problems. It cannot be said that all illnesses are from nerves and stress. For example, healthy people can manage stressful experiences and situations. However, many people have weaknesses that can turn into full-blown health issues or diseases in the future. The nervous system, when overstressed, can increase the likelihood that issues occur.
