The body can react to caffeine in both positive and negative ways. Because it stimulates the central nervous system, it can improve mood, increase alertness, and improve physical performance. Consuming caffeine in moderation can also provide antioxidants and improve cognitive function. Caffeine overuse, however, can result in dependence or digestive problems in addition to insomnia, anxiety, and elevated heart rate. Overconsumption of caffeine can also affect bone health over time and disrupt sleep. Caffeine should be taken in moderation to prevent these side effects.

When someone needs caffeine to function normally, they develop a physical dependence on it, which is known as caffeine addiction. Because of tolerance brought on by frequent, heavy use, more caffeine is required to produce the same effects. Withdrawal symptoms like headaches, irritability, exhaustion, and trouble concentrating can happen when caffeine consumption is abruptly cut back or stopped. These symptoms usually appear 12 to 24 hours after the caffeine is consumed and last for a few days. By altering neurotransmitters like dopamine, caffeine stimulates the brain, making people feel more alert and energized. This leads to a vicious cycle of dependence. Caffeine addiction can affect daily life and health, even though it is typically less severe than addictions to substances like alcohol or drugs. Caffeine dependence can be managed or avoided by gradually cutting back on caffeine consumption and enhancing sleep patterns.
