Positive thinking may help strengthen the immune system, according to new research highlighting a link between mental processes and the body\u2019s natural defences, as reported by The Guardian. Scientists found that people who actively stimulated the brain\u2019s reward system showed a stronger immune response following vaccination.<\/p>\n\n\n\n
The study indicates that participants who used positive mental strategies produced higher levels of antibodies after receiving a vaccine compared with others. Researchers stressed that optimism alone cannot prevent or cure disease, but the findings suggest mental approaches could potentially support immune responses to infections or even help the body resist tumour growth.<\/p>\n\n\n\n
Scientists said the research provides the first apparent causal evidence in humans that activating the brain\u2019s reward system can improve the effectiveness of immunisation. Previous studies have linked positive expectations to health benefits through placebo effects, but clear evidence in humans has been limited.<\/p>\n\n\n\n
Published in Nature Medicine, the study involved healthy volunteers who took part in brain-training sessions using real-time feedback to increase activity in specific brain regions. After four sessions, participants received a hepatitis B vaccine, and blood tests conducted weeks later measured antibody levels.<\/p>\n\n\n\n
Researchers found the strongest immune responses in individuals who successfully activated the ventral tegmental area, a key part of the brain\u2019s reward system, often by imagining positive outcomes. Experts caution that the effect was modest and requires larger trials to confirm clinical value, but agree it could serve as a complementary approach alongside established medical treatments, not a replacement.<\/p>\n","protected":false},"excerpt":{"rendered":"
