Curious about what will happen to your body if you drink black coffee continuously for 30 days? Here’s what experts say about the benefits and side effects of having it.
Potential Benefits
Improves focus and alertness: Black coffee contains caffeine, which enhances cognitive function, resulting in improved focus, concentration, and memory.

Full of antioxidant properties: Black coffee is rich in antioxidants that help to protect the body against the cell damage caused by free radicals.
Potential Side Effects
Sleep disruption: Overconsumption of caffeine can interfere with your sleep cycles, leading to insomnia and poor sleep quality.
Anxiety and jitters: Some individuals are sensitive to caffeine, and when they consume black coffee on an empty stomach, they experience anxiety, jitters, and even panic attacks.
Digestive issues: Coffee can increase stomach acid production, potentially leading to digestive problems such as heartburn, acid reflux, or stomach cramps, especially in individuals with sensitive stomachs.
Dehydration: Coffee is diuretic in nature, which means it can increase urine production, potentially leading to dehydration if not balanced with adequate water intake.
Tooth discolouration: Black coffee contains tannins, a component that is known as tannic acid. This can cause staining and yellowish discolouration of the teeth. Therefore, it is important to pay attention to how your body reacts to coffee and adjust your intake accordingly.
