Daily patterns of salt in urine and nighttime blood pressure: how the timing of salt intake matters

Blood pressure typically declines by approximately 10-20% at night compared to daytime levels.

• Nocturnal hypertension and impaired blood pressure dipping may be linked to negative cardiovascular and kidney health outcomes.
• Disruption of the normal circadian rhythm in blood pressure is common across different populations.
• Renal sodium excretion also follows a circadian pattern, primarily occurring during the daytime.
