Popular 'Ice' Vape Flavors May Have a Hidden Effect on Your Heart
Popular 'ice' vape flavors may impact heart health beyond just the cooling sensation.Summary
For years, flavor additives in e-cigarettes were considered secondary to nicotine, but research now suggests certain compounds, like menthol and synthetic cooling agents, may have independent health effects. These substances activate the body's cold sensor, TRPM8, creating a cooling sensation that can encourage deeper inhalation. A recent study in mice found that menthol-containing aerosols raised heart rate and blood pressure and increased irregular heartbeats. Laboratory studies also indicate that these flavoring chemicals can damage blood vessel cells, increasing inflammation and stress, even in the absence of nicotine. While this does not prove they cause heart disease, the findings suggest these compounds are not biologically inactive and warrant further investigation.
