Beetroot juice helps keep blood pressure steady in the cold
Nitrate ingestion blunts the increase in blood pressure during cool air exposure: a double-blind, placebo-controlled, randomized, crossover trial
Not medical advice. For informational purposes only. Always consult a healthcare professional. Terms
When it's cold, blood pressure usually goes up. This study tested if eating beetroot juice (which has nitrate) helps stop that rise.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

Bacteria in the mouth help regulate blood pressure by converting nitrate to nitrite, which is part of the body's natural blood pressure control system.
When you drink beetroot juice in a cool room, your body produces more nitrite in your blood than when you drink it in a warm room.
When you're in a cool room, you produce more saliva than when you're in a warm room.
Drinking beetroot juice in a warm room doesn't make your blood pressure go down compared to drinking a placebo in the same warm room.
When you're in a cool room, your saliva has more nitrite after drinking beetroot juice than when you're in a warm room.
