"Once, there was a supervisor who has passed her annual breast check-up. 9 months later, a breast tumor detected and triggered her at 2nd check-up. She was shocked with the results as 2nd stage breast cancer! According to the specialists, it takes 5, 10 or even up to 15 years for the accumulated toxin to form a cancer. How did the 9 months build up for her 2nd stage cancer? It was found that ever since her Chief Editor promotion at last year, she has been under tremendous stress and lost her lifestyle rhythm ………."
The case above implies that emotion and stress are the trigger of illness.
Stress affects our health via Autonomic Nervous System and Endocrine System. When under stress, our body will reprioritize the resource distribution to various parts of organs, to focus its energy. Low cortisol (a hormone secreted by kidney) will induce volatile blood sugar level, tiredness and loss of energy. If stress prolong, excessive cortisol will induce instability of blood pressure, excessive gastric acid, muscle and joint pain, obesity that affecting fat distribution, poor memory, and suppress the immune system. A continuous 20-minute of cortisol secretion can suppress the immune system for up to 3 days!
In fact, most of the case studies show that the illnesses, especially the cancers, have been manifested through the suppressed emotional and unreleased stress from a series of major life events, even before medical diagnosis.
In summary, besides the trauma from natural disasters, most of the illness is related to emotions (happiness, anger, worry, anxiety, sadness, fear, fright). For example, you are happy when praised; you are angry when scolded or insulted, even blood pressure might be elevated, heart beat might be accelerated and trigger a heart attack. On top of these, those who have worries, anger and depression are mostly ended up with liver diseases like liver cancer or cirrhosis. As preached in the traditional Chinese medical study, anger is bad for liver. While emotion is a state of mind, although it is out of reach, it controls our health. In other words, our emotions influence our organs.
