That really depends on your doctor. Some people are high at 140 and others at 130 for the systolic. If you are young, I think 130 is pretty high. If you are older maybe 140 if the point where you should be paying attention.
For the diastolic 80 is good. 85 is take a note book when you go see a doctor and 90 it's time to be a worry wart.
These are just numbers. Throughout the day, the numbers can vary quite a bit so one bad reading does not make you a candidate for high blood pressure.
If you learn to relax before it is taken, it makes a 10 - 15 point difference on the systolic and don't let people bully you about it.
Heat exhaustion is when your body starts to decline from the heat but not too much and your body just starts to get exhausted from the heat but with a heat stroke your body just starts to give up and it's too much heat almost similar to an regular stroke just with heat *hope this helps*
It's d as she would need to explain the study and tell the people that are participating in the study that they can leave
