Does thinking about getting sick actually makes you sick? if so is it the same sickness that you thought of?

Sometimes: It is true that sometimes if you worry excessively about getting sick, you will feel ill. Our minds can influence our bodies and make us feel ill, and have various symptoms, such as headaches, nausea, chest pain, etc. However, you can't actually get an illness such as pneumonia, AIDS, etc just by worrying about it. Try to relax! Good luck!

Thinking sickness.: Some people get the feeling that they will vomit, before they actually do the act. That can be expected.

Predisposition : There has not been a large study that demostrates that a thought translates into disease. Is also very hard to asses this situation (let's start with the definition of a thought!). Bottom line the answer is No.
