FUN FACTS; WHAT HAPPENS TO THE BLOOD PRESSURE WHEN WE ARE DEHYDRATED

Water is very important in regulating our blood volume. Our blood volume affects blood 

pressure, how much we pee and urine concentration (dilute or concentrated). When we are 

dehydrated, our blood volume decreases causing a low blood pressure. Low blood pressure 

causes our heart to start beating very fast. When the hypothalamus, detects low blood volume 

or little water in our blood, it signals the release of anti-diuretic hormone (ADH) which 

causes the kidney to remove less water in and to return blood pressure back to normal.

THE RESULT; We urinate less and our urine is usually more concentrated and darker in 

color. 

STAY HYDRATED
