Why is mixing alcohol with energy drinks potentially dangerous?

• A. Caffeine masks impairment, may lead to higher consumption, dehydration, and heart stress.
• B. It causes drowsiness and slower reaction times.
• C. It makes drinks taste better.
• D. It prevents dehydration.

Answer: (A)

Mixing alcohol with energy drinks is risky because caffeine can mask how intoxicated you are. The stimulant can hide signs of impairment, so you might not realise you’ve had too much, leading you to drink more than you planned. That can increase the chance of harm, including dehydration and stress on the heart, since caffeine and alcohol together place extra strain on the body’s fluids and cardiovascular system. The other ideas don’t fit because drowsiness isn’t a typical result of energy drinks (they’re stimulants that counteract tiredness), they don’t make drinks safer in taste or preference, and they don’t prevent dehydration—in fact, they can contribute to it.
