“Who does not love a study that validates one of life’s habitual pleasures?”⠀⠀⠀⠀
For years, doctors have oscillated on the potential risks and benefits of coffee. Fortunately for coffee lovers everywhere, the news in recent years has mostly been positive—and a recent study is no exception. In addition to coffee’s other health benefits (studies show it has been associated with a lower risk of cancer, cardiovascular disease, type 2 diabetes, chronic liver disease, Parkinson disease, Alzheimer’s disease, and depression), scientists now say that coffee may be good for our skin.⠀
In a study published in JAMA Dermatology of more than 82,000 participants who were followed as part of a national study from 1989 to 2005, study authors report higher caffeine intake was associated with lower rosacea risk after adjustment for several confounders. ⠀⠀⠀
The authors hypothesise that caffeine’s vasoconstrictive and immune suppressive effects might decrease the risk of rosacea. ⠀⠀⠀
While coffee has previously been seen as a trigger for rosacea because heat from the beverage can induce symptom flares, the study found that the polyphenols from coffee could mitigate these effects.⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀
Since the study was observational, it is only able to show an association and not a cause-and-effect relationship. Nonetheless, the study provides evidence that patients with rosacea need not avoid coffee, and gives us all one more reason to continue drinking the beverage regularly.
Still, rosacea sufferers who drink coffee need to ensure it is at a reduced temperature that won’t trigger symptoms.
Relief for rosacea is better found through laser treatments, topicals, and avoiding triggers.
Further research is needed to understand the reasons for the observed association and determine why other sources of caffeine like tea, soda, and chocolate do not seem to have this same effect on rosacea risk.⠀
