Drinking two cups of coffee a day is generally considered safe for most healthy adults. Research suggests that up to 400 milligrams (mg) of caffeine daily is safe, which equates to about four cups of brewed coffee. However, it's important to note that caffeine content varies greatly between beverages, especially energy drinks. While two cups of coffee may provide some health benefits, such as improved cognitive function and a reduced risk of certain diseases, excessive caffeine intake can lead to negative consequences like anxiety, insomnia, and heart palpitations. For individuals with pre-existing health conditions, it's crucial to consult with a doctor before consuming large amounts of caffeine.
While some studies suggest that drinking more than two cups of coffee a day might increase the risk of cardiovascular disease, especially in individuals with severe hypertension, the overall impact of coffee consumption on health remains complex and depends on individual factors. Ultimately, it's essential to moderate caffeine intake and be mindful of its potential effects on your body.
