caffeine tolerance

Caffeine tolerance occurs when regular consumption of caffeine reduces its effects on the body. Over time, as you consistently consume coffee, tea, or energy drinks, your body adapts, requiring more caffeine to achieve the same level of alertness and energy. This happens because your body’s chemistry changes, leading to fewer receptors for caffeine or altered responses in the brain. As a result, what once provided a boost may feel less effective, prompting some to increase their intake to regain the desired effect. Tolerance can develop differently in individuals, influenced by genetics, habits, and overall health.
