Winter’s up ahead, and low temperatures cause blood vessels to constrict and increase blood pressure (BP). The question is how these mechanical changes in blood vessels are translated to the brain?

Blood pressure is maintained within a normal physiological range by a sophisticated regulatory mechanism. Baroreceptors serve as a frontline sensor to detect the change in blood pressure.

Conversely, when a change to a standing position is made, baroreceptors are unloaded, allowing vasoconstriction and tachycardia to buffer the fall in blood pressure that would otherwise occur.

Having more fluids in the body directly increases blood pressure levels. Alcohol also decreases baroreceptor sensitivity. Baroreceptors are types of receptors present in the body that help ...

Medically reviewed by Anisha Shah, MD Blood pressure may rise with age, increasing cardiovascular disease risk. However, ...

Researchers have determined the location of natural blood-pressure barometers inside our bodies that have eluded scientists for more than 60 years. University of Virginia School of Medicine ...

Both high and low blood pressure can be problematic, so to keep it in the goldilocks zone the body has “baroreceptors” that sense blood pressure. The main ones are located in the carotid sinus ...

"Of course, I was a little scared." It stimulates baroreceptors, which are special sensors that detect pressure changes in blood vessels. When you have high blood pressure or heart failure for a ...

Carotid sinus baroreceptors are involved in controlling blood pressure (BP) by providing input to the cardiovascular regulatory centers of the medulla. The acute effect of temporarily placing an ...

It interferes with calcium levels in smooth muscle cells that regulate blood vessel dilation and constriction. Additionally, alcohol impacts baroreceptors—pressure sensors that help regulate ...
