Caffeine addiction occurs when a person develops a dependence on caffeine, a stimulant found in beverages like coffee, tea, and energy drinks. Regular consumption can lead to tolerance, meaning that over time, individuals may need to consume more caffeine to achieve the same effects, such as increased alertness and energy. Withdrawal symptoms can arise when a person suddenly reduces or stops caffeine intake. These symptoms may include headaches, fatigue, irritability, and difficulty concentrating. Understanding caffeine addiction is important for managing consumption and maintaining overall health, especially for those who rely on it to function daily.
