what is the effect of the positions, sitting, standing, and lying down on blood pressure and why?

lying down,sitting,standing,etc don't make that much difference. You aren't looking for someones blood pressure after they have been running around, you want resting pressure. If the person has been lying around awhile and then jumps up and runs awhile then the difference between sitting pressure and what you started with before they ran,will notably be different. I have veins that are hard to get a pressure from so I raise my arms and squeeze my hands to get more pressure flowing through my arms which will cause my blood pressure to be read easier.

The top number (systolic) is the maximum pressure in the artery (when the heart beats). The bottom number (diastolic) is the lowest pressure in the artery (when the heart is at rest). "Too low" is determined by if it affects the person. Low blood pressure can mean dizziness or fainting. If that's not a problem, then it's not too low. The main problem with blood pressure is when it gets too high, because then it affects the arteries, which can lead to other problems. As long as he's feeling well, that's excellent blood pressure for someone his age.

Sitting is the usual way.  Some take it while you are lying down.

Smoking increases the activity of the sympathetic nervous system, putting additional stress on the system that regulates the heart and blood vessels. \n\nFor more information on the effects of smoking, visit the website below.

It can aggravate back problems, especially if the monitor is not placed right causing poor posture in the chair. Also if the monitor isn't positioned correctly it can cause neck strain due to holding the head in an anatomically incorrect position. Neck strain can also be caused by looking at text being transcribed if the copy is not positioned properly. Prolonged keyboarding year after year can lead to arthritis of the fingers.

I think a better title would be something like: The Effect of Music Genres on Blood Pressure.  Make sure to include hypothesis, materials, procedure, observations, and conclusion.

Your entire body is pretty much on a level with your heart when you're lying down. When you stand up, your head, shoulders and upper chest are higher than your heart. Standing up, your heart has to pump harder to push the blood up to your head (and your brain in particular has a good blood supply). The heart pumping harder means the blood pressure is raised.

That's not an abnormal reaction.  Your blood pressure dropped suddenly as you stood, because blood tries to pool in your legs. This is usually stopped by nerves, which contract the veins in your legs ensuring that enough blood returns to your heart and that there is no reduction in the amount of blood that your heart pumps. This maintains the blood supply to your brain.\n\nHowever, if there is pooling of blood in your veins, less blood returns to your heart and less is pumped out which means a reduction in the amount of blood going to your brain. This causes symptoms of dizziness and some people may faint. \n\nIf you have low blood pressure and you also have symptoms of dizziness or faintness when standing up suddenly you should have your blood pressure checked, both when you are lying down and when you then stand up. This drop in blood pressure when you stand up is called orthostatic hypotension.\n\nSee this site http://www.merck.com/pubs/mmanual_ha/sec3/ch20/ch20b.html for an explanation of some possible causes of low blood pressure.

Increased BP can put stress on you arteries, veins, and organs.  Increased BP can lead to kidney failure, heart attacks, strokes, etc.  A good way to keep your BP down is to exercise regularly and eat right.

What happens is that laying down for hours allows blood to pool up, and this aids in the likelyhood that you will have a morning erection.

If your blood pressure is over 140/90, then you have high blood pressure or hypertension ... provided that the BP measurement was taken correctly, and you were well rested when the measurements were taken.  Hypertension if uncorrected, damages your heart, kidneys, and increases the risk of stroke.  All these occurs while you're feeling ok ... that's why it's often coined as the "silent killer".\n\nYou are pre-hypertensive.  Not normal.  This subgroup is there to emphasize the importance of prevention.  That means more exercise, watch the salt in your diet, quitting or cutting down on alcohol, smoking, etc.  Lifestyle changes mostly.  The good news is that you don't need to take any medications.\n\nHope that helps.

I heard it's worse when sitting. The circulation to your legs is cut off. When your lying down your blood tends to pool in your legs which is also uncomfortable.

“We” can be in one position for more than 15 minutes. Maybe you can’t, but that doesn’t mean that other people can not. The average soldier for example spends more than 15 minutes standing to attention every day on average.\n\n\nThe reason you “feel as though ur circulation is slowing” is because blood requires muscles contractions to find it way back to the heart. If you sit still you are not using your muscles and as a result the blood pools in the extremities.\n\nYour inability to keep your arm up straight is a totally unrelated phenomenon. Your arm hangs DOWN when at rest. To keep it up requires you to use the muscles in the arm and shoulder. Your arm gets tired simply because you lack the muscles required to keep it there. It is quite simple to develop the muscles to allow you to hold your arm up for hours at a time if you wish, and most house painters do just that. You lack those muscles, so your arm gets tired.\n\nIf you find yourself unable to remain in one position for more than 30 minutes without developing a cramp you  should see your doctor. That’s a string indication of a circulatory problem or anionic imbalance. Any normal young person should be bale to remain in one position for far longer than that without effort if they are sitting or reclining.  It may not be comfortable but you should definitely not be getting cramps.

In certain conditions yes this is normal.  The big question is "How do you (the patient) feel?"  Some people need a low BP and some people have a heart so poor that it is unable to produce a high BP.  When the BP decreases the heart rate may elevate as a compensatory mechanism to help supply the body with blood. In this circumstance low BP high HR is entirely normal. However, if your BP is so low that you are getting dizzy , feel terrible, tired lethargic you may need further medical advice

When I have low blood pressure, I get dizzy and feel week.  I usually get low blood pressure when I am dehydrated.  \n\nAccording to NANAY.com people with low blood pressure may experience: \n"tiredness, sleep disturbances, giddiness, black-outs, fainting, anxiety/depression, or sweating, and may become more conscious of their heartbeats."
