Why is high blood pressure bad?!
Question: it doesn't make any sense to me because excercise increase's your blood pressure and excercise is good for you but they say a high blood pressure is bad for you.
i'm confused????????????????????????????????

Well it's bad if it stays up for a long time. I had a echogram done, and one part of my heart is enlarged, and this can be caused by high blood pressure. It's only enlarged a little but I have to take care, when the heart gets bigger it has to work harder to pump blood..
also high blood pressure can damage your kidneys.
High blood pressure over a prolonged period of time (for example all day even when you aren't exercising) is bad. It puts more stress on the walls of your arteries which could lead to damage of them - also called atherosclerosis. Atherosclerosis is when the walls of your arteries become cracked. When this happens it's easier for fat to buildup and eventually cause a heart attack or stroke.

high blood pressure causes strokes and heart attacks believe it or not most happen whilst exercising.
Hypertension (high blood pressure) is bad because it puts BAD stress on your heart. Your heart is a muscle so it need some stress to become stronger like when you exercise and it pumps faster but over long periods or time that can be bad as well. Your heart has 4 little rooms in it it connects to your lungs to pick up oxygen and take it to your body and then comes back to the lungs and heart to dispose of the Carbon dioxide that your body put off. So when you're blood is moving so quickly through your body it doesn't allow time for oxygen to be exchanged and recycled. and think about this when you do sit ups st first it's easy isn't it? but then it gets a little harder but that ok because you stop and you get stronger because of it. But lets say you just kept doing sit ups, for hours just up and down up and down, you'd be exhausted! You couldn't accurately do your job if you had to do sit ups all day everyday, and neither could the heart ^-^
First you need to understand exactly what blood pressure is and what the figures represent. Blood pressure is simply the amount of pressure that would need to be applied to an artery in order to stop the pulse flow. Blood pressure is given as two figures, a systolic figure and a diastolic. We all know a heart pumps, that is beats and pumps blood and then beats again. The systolic figure is the pressure when the heart pumps and the diastolic is the pressure when the heart is between beats. The measurement is (in the UK anyway) mm Hg (mil's of mercury) but this is not relevant to your question. So why is high blood pressure bad?....Imagine you had a hose and turned the tap on at a set level so that water was coming out of the end. Now if you held you finger over the end of the hose reducing the diameter by say a half we all know the water spurts further. This is because the same amount of water needs to pass through a smaller gap, the rate at which the water travels is the pressure. the same is true of your blood vessels. a high blood pressure, when at rest, suggests your arteries may be reducing in diameter as a result of deposits on the inside of the vessel walls. I time this reduced blood flow may lead to insufficient blood getting around the body and as it is the blood that carries oxygen the consequence of this are obvious, not to mention your heart is working harder than it needs to!. The problem is, continuous high blood pressure can damage the artery walls and as scar tissue repairs it the blood vessels are reduced in diameter - so high blood pressure leads to higher blood pressure!
A higher systolic figure may be high for a number of reasons such as your mood, how nervous you are, after a hot bath and the such like but an elevated diastolic is a more sure indicator of hypertension.
You are correct your blood pressure increase during exercise as the body needs the oxygen, for the exercise. This is why you breath faster and you heart pumps faster (the increase in pulse rate) However this is just a temporary situation and your blood pressure and heart rate will return to normal. Indeed I would contest the best way to measure someone's cardio fitness is to measure how quickly their pulse rate returns to normal following exercise.
Hope this helps. Possibly a doctor or nurse may give a better, more detailed answer but I hope this is of use to you initially
