It will…IF you THINK it will! Medical experts call it the “no-cebo effect.” The opposite of the placebo effect – in which, if you think a pill will make you feel better, it will – even if it’s only a Tic-Tac in disguise. With the nocebo effect, if we expect negative symptoms, we can actually trigger them. That’s how powerful our minds are. So stop and think about whether your fears are realistic… So you can stop worrying yourself sick.
