Drinking more than 4 cups of coffee a day causes negative effects.
Coffee has become a daily habit for many to refresh themselves upon waking and to increase attention. However, experts say that drinking more than four cups of coffee a day can have negative effects on health.
Excessive coffee consumption can result in insomnia, tension, anxiety, and memory weakening. Drinking coffee late at night disrupts the sleep cycle and weakens morning mental activity.
Experts recommend consuming 300-400 milligrams (approximately 3-4 cups) of coffee per day, with one to two cups in the morning being sufficient.
