Your emotions and thoughts play a major role in your health. Think about something that you really hate or someone who really bothers you. It is actually possible to increase your heart rate, tense up your shoulders, bring on a headache, or make yourself sick to your stomach by just thinking about it! Or, think about a bright yellow lemon. See it clearly in your mind’s eye. Now, picture cutting the lemon right down the middle. Then picture yourself picking up half and squeezing the juice out right into your mouth on top of your tongue, and you swallowing the juice. Did you salivate more just thinking about it? Can you see how what you think can actually change your bodily function?
