The experience of feeling unwell after consuming coffee stems from a variety of physiological and chemical interactions within the body. This adverse reaction can manifest in several ways, including nausea, anxiety, digestive discomfort, and heart palpitations. For example, an individual might experience heartburn shortly after drinking a cup of coffee, or another might feel jittery and anxious.
Understanding the factors that contribute to this negative response is beneficial for individuals seeking to enjoy coffee without the associated discomfort. It allows for informed choices regarding consumption habits, brewing methods, and potential underlying health conditions. Historically, anecdotal reports of such negative reactions have prompted scientific investigation into the specific components of coffee that might trigger these effects.
