Can you have too much coffee?

Yes. Consuming too much caffeine, the stimulant in coffee, can lead to several adverse effects, including:

Anxiety: Caffeine can cause anxiety and nervousness in some people, especially those who are sensitive to its effects.

Jitters: A high intake of caffeine can cause the body to feel restless and jittery, making it difficult to relax.

Insomnia: Consuming too much coffee before bedtime can disrupt sleep patterns, leading to insomnia.

Headaches: Caffeine can cause headaches, especially in people who are prone to them.

Increased heart rate: High caffeine intake can increase the heart rate and cause palpitations.

Dehydration: Coffee is a diuretic, which means it can lead to dehydration if consumed excessively.

Digestive problems: Coffee can irritate the digestive tract, causing stomach pain, diarrhoea, or constipation.

Caffeine dependency: Frequent and excessive coffee consumption can lead to physical dependence, causing withdrawal symptoms such as headaches, fatigue, and irritability when the intake is reduced or stopped.

It's important to consume coffee in moderation and be mindful of your own tolerance to caffeine. The recommended daily intake of caffeine varies among individuals based on factors such as body weight, age, and sensitivity to caffeine. Generally, healthy adults can safely consume up to 400 milligrams (mg) of caffeine per day, which is equivalent to about four cups of coffee. However, it's always best to consult a healthcare provider if you have concerns about your caffeine intake or experience any adverse effects from drinking coffee.
