Caffeine masks alcohol’s sedative effects, making people feel more alert than they actually are, leading to overdrinking.
Because caffeine reduces the perception of intoxication, individuals often consume more alcohol, raising the risk of life-threatening alcohol overdose.
Impaired coordination remains despite feeling “awake,” resulting in more accidents, falls, and drunk-driving incidents.
Both alcohol and caffeine affect the cardiovascular system differently; together they can overstimulate the heart, causing palpitations, irregular rhythms, or even sudden cardiac events.
Alcohol is a diuretic and caffeine increases fluid loss. Together, they speed up dehydration, which can lead to headaches, fatigue, and heat-related illnesses.
Studies show that mixing the two increases risky behaviors such as unsafe driving, unprotected sex, or aggressive conduct.
Caffeine spikes blood pressure temporarily, and when combined with alcohol’s vascular effects, it can pose risks for hypertensive individuals.
The dehydrating effects of both substances intensify hangover symptoms, making recovery much more difficult.
