Synthetic Cooling Chemicals in E-Cigarettes May Increase Heart Rhythm Risks, Study Finds TALMedora Health Desk Cardiology | Public Health | Tobacco Research Electronic cigarettes are often marketed as a safer alternative to traditional smoking. However, growing evidence suggests that vaping may carry cardiovascular risks that extend beyond nicotine itself. A new study published in Circulation: Arrhythmia and Electrophysiology has identified a potential concern involving synthetic cooling agents commonly used in e-cigarettes. Researchers found that these additives may increase the risk of abnormal heart rhythms and disrupt the body's autonomic control of the heart. Many modern vaping products contain cooling compounds designed to create a mint-like sensation without adding traditional menthol flavor. Among the most widely used are: * WS-23 * WS-3 * Menthol These ingredients have become increasingly popular in "ice" and "cool" flavored vaping products, particularly among younger users. While they improve the sensory experience, their long-term health effects have remained largely unknown. Researchers evaluated the cardiovascular effects of cooling agents using both animal models and human heart cells grown in laboratory conditions. The study examined how cooling agents affected: * Heart rate * Heart rhythm stability * Electrical activity of the heart * Autonomic nervous system balance * Ventricular arrhythmias The goal was to determine whether these additives contribute independently to cardiovascular risk beyond nicotine exposure alone.
