5. It could cause or worsen acid reflux
Many coffee drinkers have complained of acid reflux, reporting that it worsens after drinking coffee. This has lead researchers, once again to find the source of the complaint. Some cite the acidity in coffee, while others believe it to be the caffeine and the way it is prepared.

While the research is not concrete, many still complain of the heart burning effects. If you believe coffee is to blame for your heartburn, you may want to abstain. However, if you want to continue to drink your beans in a warm mug, try avoid brewing methods like espresso or french press that don’t use paper filters that catch oil droplets in the coffee that contain stomach irritants. Perhaps try cold-brewed coffee to prevent the heat factor.
