Abstract [en]

We 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 andlt; 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.
