Named the unexpected danger of consuming cold drinks

Cold tea and lemonade can become unexpected triggers of dangerous cardiac arrhythmia. Researchers have discovered a surprising connection between icy drinks and episodes of atrial fibrillation in patients diagnosed with atrial fibrillation (Afib). The results of this discovery were published in the authoritative journal Journal of Cardiovascular Electrophysiology.

The study showed that in some survey participants, cold drinks regularly provoked episodes of heart rhythm disturbances. About half of the patients reported complete cessation of attacks after excluding icy drinks from their diet. Others noted significant relief of symptoms when consuming drinks at room temperature, avoiding the use of straws, or drinking slowly.

The scientific explanation for this phenomenon is still under investigation. Cardiologist Grant Simons from Hackensack University Medical Center suggests that the vagus nerve, which is responsible for regulating heart rhythm, plays a key role. In predisposed individuals, sudden cooling of the oral cavity can trigger a cascade of reactions that disrupt normal heart function.

Specialists note: "Cold drink syndrome" is not a universal phenomenon, however, patients who notice a correlation between consuming cold liquids and heart malfunctions are advised to consult a specialist. Sometimes a minor adjustment to daily habits can significantly improve control over the disease.

Earlier scientific studies have also revealed the influence of various drinks on mental health. It was found that carbonated beverages with sugar or artificial sweeteners increase the likelihood of developing depression, while natural juices and coffee may have a protective effect.
