When is our blood pressure higher? While standing or while lying?

Answer 1

Most commonly, blood pressure is higher when standing. When you stand up, your brain sends signals to your blood vessels to clamp down to keep blood pressure high enough so blood can reach your brain and keep you awake!. When you lie down, you and your blood vessels tend to be relaxed, and blood can reach your brain even if your blood pressure is relatively low.

Answer 2

The pressure of blood against the the walls of the main arteries. The pressure is high during " Systole " , when the ventricles are contracting ( systolic pressure ), and the lowest during " diastole " , when the ventricles are relaxing and refilling ( diastolic pressure ). The BP is measured by means of a "sphygmomanometer " at the branchial artery of the arm, where the pressure is more similar to that of blood leaving the heart. The normal range varies with age, but a young adult would be expected to have a systolic pressure of around 120 mm and a diastolic pressure of 80 mm. These are recorded as 120/80.

Individual variations are common. Muscular extension and emotional factor, such as fear, stress, and excitement, all raises BP. Systolic BP is normal at its lowest during sleep. Severe shock may lead to an abnormally low BP, and possible circulatory failures. The BP is adjusted to its normal level by the " sympathetic " nervous system and hormonal control.

Answer 3

Blood pressure fluctates throughout the day, but generally when you are standing, you are more active anyway and your blood pressure may be higher.

This is not always the case, however. If you are lying down for a period, then stand up rapidly, your blood pressure rapidly drops due to orthostatic hypotension (venous pooling causes blood to pool in the lower extremities). This is rapidly compensated, however, via an increase in heart rate and vasoconstriction, thus bringing mean arterial blood pressure back to normal. This sudden drop in blood pressure is why some people faint when they stand up rapidly.

Answer 4

3 years ago, I was diagnosed - hypertension with a reading of 160/100. I used to feel dizzy a lot, my legs had awful cramps, and levels were very low in my potassium, causing my fingers and toes to always cramp together. One day I started to feel really faint while I was driving with my daughter in the back seat and I passed out, hitting 3 cars and ending up in a ditch. That moment,I knew I had to do something because my meds weren't working. I heard about this diet from a friend and thought I'd give it a shot. The results have been remarkable. In just 21 days, I honestly can't remember feeling this good, my blood pressure went from 175/110 to 125/70.
