Randomized Controlled Trial Doubling of water intake increases daytime blood pressure and reduces vertigo in healthy subjectsAnders Jormeus et al. Clin Exp Hypertens. 2010. AbstractWe studied the effect of increased water intake on ambulatory blood pressure (BP) in healthy individuals. Blood pressure was recorded after 2 weeks of either regular (RWI) or extra water intake (EWI, an additional 30 ml water/kg body weight per day) in 20 healthy subjects (10 males, 10 females). The extra water intake (RWI: 1.7 ± 0.59 l, EWI: 3.7 ± 0.84 l, respectively, p < 0.0001, i.e., an increase of 2 liters) induced an increase in mean arterial daytime BP from 89.0 ± 5.5 mmHg during RWI to 91.4 ± 6.4 mmHg during the EWI phase (p = 0.005), while night-time BP was unchanged by the intervention. The visual-analogue-scale (VAS, maximum score of 10) score corresponding to the statement "I often experience vertigo" was 3.1 ± 2.6 during RWI and decreased to 2.1 ± 2. 1 during EWI phase (p = 0.008). In conclusion,two liters of extra water intake for 2 weeks significantly increased daytime blood pressure and reduced a sense of vertigo in healthy individuals. Similar articles

How long does it take for blood pressure to go down after drinking water?Blood pressure started increasing within two or three minutes after the water was ingested, increased rapidly over the next 15 minutes, and then began to decrease after about 60 minutes. Drinking more water at 60 minutes caused the blood pressure effect to be sustained for another hour.
Does blood pressure go up after drinking water?Water drinking also acutely raises blood pressure in older normal subjects. The pressor effect of oral water is an important yet unrecognized confounding factor in clinical studies of pressor agents and antihypertensive medications. (Circulation. 2000;101:504-509.)
Does drinking water lower blood pressure or raise it?Something as simple as keeping yourself hydrated by drinking six to eight glasses of water every day improves blood pressure. Water makes up 73% of the human heart,¹ so no other liquid is better at controlling blood pressure.
Does drinking water before a blood pressure test help?DRINK A FULL GLASS OF WATER 45 MINUTES BEFORE YOUR EXAM
If this is not in the cards for you, then a full glass of water 45 minutes before you take your test will help flush your system, prepare you for your urine sample, and lower your sodium levels.
