Which statement best describes the effects of caffeine intoxication?

• A. Decreased heart rate and sedation
• B. Increased energy and alertness
• C. Severe drowsiness and confusion
• D. Muscle relaxation and impaired coordination

Answer: (B)

Caffeine is a central nervous system stimulant that primarily affects the brain by blocking the neurotransmitter adenosine, which promotes sleep and relaxation. As a result, the consumption of caffeine typically leads to increased energy levels, heightened alertness, and improved concentration. These effects are often accompanied by physical responses such as increased heart rate and respiration, making individuals feel more awake and active. The statement regarding increased energy and alertness accurately encapsulates the effects of caffeine intoxication. This stimulation contrasts sharply with symptoms related to other substances or conditions, such as sedation or drowsiness, which are typically associated with depressants or certain medical conditions. Thus, the correct choice effectively represents the chief effects of caffeine and aligns with its pharmacological profile as a stimulant.
