Drinking coffee daily can have both positive and negative effects on the body. The caffeine in coffee stimulates the central nervous system, helping to improve alertness, focus, and mood. It can also boost metabolism and increase physical performance by releasing adrenaline. Regular coffee consumption has been linked to a reduced risk of several diseases, including Parkinson’s, Alzheimer’s, and type 2 diabetes, due to its antioxidant properties.

However, excessive coffee intake can lead to restlessness, anxiety, and disrupted sleep patterns. Over time, it may also cause a tolerance to caffeine, requiring more to achieve the same effects. Additionally, too much coffee can irritate the stomach, leading to acid reflux or digestive issues. Moderation is key for maintaining its benefits while avoiding negative side effects.
