Coffee consumption lowers risk of rosacea, says study
Consuming caffeine from coffee is associated with a lower risk of rosacea in women, according to a study published in the journal JAMA Dermatology.
Caffeine is known to decrease vasodilation and have immunosuppressant effects, which may potentially decrease the risk of rosacea. The cohort study of 82,737 participants in the Nurses’ Health Study II identified 4,945 incident cases of rosacea and found a significant inverse association between risk of rosacea and increased caffeine intake, particularly that from coffee.
This association was not found for caffeine intake from other food sources such as tea, soft drinks and chocolate. All analysis took place between June 2017 and June 2018.
The study found that increased caffeine intake from coffee was inversely associated with the risk of rosacea.
The authors concluded: “Our findings do not support limiting caffeine intake as a means to prevent rosacea and may have implications for the causes of and clinical approach to rosacea. Further studies are required to explain the mechanisms of action of these associations, to replicate our findings in other populations and to explore the relationship of caffeine with different rosacea subtypes.”
However, the heat from coffee may be a trigger for rosacea flares. As such, the relationship between the risk of rosacea and caffeine intake, including coffee consumption, is poorly understood.
