Heart Health Alert: Ditch the Ice-Cold Water!
8 Dec
Summary
- Drinking ice-cold water can constrict blood vessels, increasing heart strain.
- Sudden cold water intake may trigger the vagus nerve, affecting heart rhythm.
- Room temperature water is recommended for heart patients to avoid stress.
Consuming ice-cold water can have detrimental effects on cardiovascular health, particularly for individuals with a history of heart conditions. The extreme cold causes blood vessels to narrow, a phenomenon known as vasoconstriction. This forces the heart to work harder to pump blood, leading to increased stress on the organ.
This sudden strain can temporarily elevate blood pressure and is especially risky for those already managing hypertension. Furthermore, ice-cold water can trigger the vagus nerve, which plays a role in regulating heart rate. Such stimulation might induce irregular heart rhythms, dizziness, or even fainting spells.
To mitigate these risks, experts advise heart patients to opt for room temperature water. Incorporating beverages like green tea or lemon water can also support better circulation. Maintaining adequate hydration by drinking 2-3 litres of water daily is essential, with the temperature of the water being a critical factor for heart health.
