Do you remember someone telling you that if you want to warm up think warm thoughts?
Well there may be something to it.
A team of researchers led by Associate Professor Maria Kozhevnikov from the Department of Psychology at the National University of Singapore (NUS) Faculty of Arts and Social Sciences showed, for the first time, that it is possible for core body temperature to be controlled by the brain.
The scientists found that core body temperature increases can be achieved using certain meditation techniques (g-tummo) which could help in boosting immunity to fight infectious diseases or immunodeficiency.
The participants that were taught this technique to were able to elevate their body temperature, within limits, and reported feeling more energized and focused.
