Negative thoughts can lead to chemical changes in the body, producing toxins in the bloodstream, according to a study titled Bad Moods Produce Toxins. When a person exhales into an ice cup under normal mental conditions, the condensed substance is colorless and transparent. However, the condensed substance shows different colors when a person is resentful, angry, fearful, or jealous. Chemical analysis indicates that negative thinking can cause bodily fluids to produce toxins.
Research conducted by Cardiff University in the UK and the University of Texas suggests that “evil begets evil” has a scientific basis. Statistics show that although juvenile offenders are physically stronger than law-abiding peers of the same age, their health deteriorates rapidly as they reach middle age. They have a significantly higher risk of hospitalization and disability, likely related to poor lifestyle habits and psychological states.
As early as 1958, renowned American cardiovascular expert Dr. Williams began a longitudinal study on 500 medical students. After 25 years, he found that those with substantial or relatively strong “hostile emotions” toward others had a mortality rate of 96 percent. This group also had a heart disease rate five times higher than others.
Stephen Post, a former bioethics professor at Case Western Reserve University and now a professor at Stony Brook University School of Medicine, and novelist Jill Neimark conducted in-depth research on the relationship between “giving” and “receiving” from modern science and medicine perspectives.
They developed a detailed measurement table and tracked generous individuals, categorizing and analyzing the physical and physiological effects of each type of “giving.” They discovered the “medical effects” and “happiness index” generated by giving: kind and charitable people experience significant and profound impacts on their mental and physical health. Their social skills, judgment, positive emotions, and mindset are comprehensively enhanced. Even a sincere smile or a friendly, humorous expression can increase the immunoglobulin concentration in saliva.
After synthesizing over 100 research findings from more than 40 major American universities and combining data from long-term tracking experiments, researchers reached a surprising conclusion. There is a magical energy conversion secret between giving and receiving. When a person shows, the energy of receiving is returned in various forms, often without the person realizing it.
Additionally, scientists have found a phenomenon in neurochemical research: when people harbor good intentions and think positively, the body secretes neurotransmitters that promote healthy cells, and immune cells become more active, making a person less prone to illness. When positive thoughts are maintained, the immune system is strengthened. Conversely, when harboring malice and negative thoughts, the negative neural system is activated, and the positive system is suppressed, disrupting the body’s beneficial cycles.
Harvard University conducted an experiment where students watched a documentary about an American woman’s lifelong efforts to help the poor and disabled in Calcutta. Saliva analysis of the moved students showed an increase in immunoglobulin A levels compared to before watching the documentary.
