I have an example of how testing and then testing again over and over can have a big impact. A few years back I tested my blood pressure, it was slightly raised. I tested my BP again, it was even higher, so I tested it again, this time it had jumped to something like 100/160. Frightened I called 811 (the Canadian medical line) I spoke to a nurse and she asked me to test my BP again, it read 110/170. She called an ambulance and I was carted off to hospital. I lay in a hospital bed, the Dr came in and told me that my anxiety from testing has caused my BP to shoot up. He then told me a story from back when he was a med student. One of their fellow med students blood pressure was slightly raised. All the med students , including the Dr attending me, ribbed him. His blood pressure rose to such a degree he was admitted to hospital. There actually nothing wrong with his blood pressure. Like me anxiety had driven up our blood pressure.
Continually testing over and over can create a situation where our bodies become angst and that starts off a whole load of chemicals to be released In our bodies. Edited - grammar
