However, excessive consumption of coffee can lead to negative side effects, including jitteriness, nervousness, and increased heart rate. It can also disrupt sleep patterns and lead to insomnia, especially when consumed late in the day. Additionally, coffee is a diuretic, which means it can cause increased urination and dehydration in some individuals.

In some cases, individuals may experience adverse effects with even small amounts of coffee, while others may tolerate higher doses without any negative effects.
