Physical Effects of Alcohol

Alcohol usage is prevalent in our society. Centers for Disease Control statistics show at least half the population of the United States consumes alcohol on a monthly basis. Reasons for drinking are varied. Some drink to relax, some are social drinkers, yet others are satisfying an addiction. Though age, gender, weight and food intake can affect sensitivity to intoxication, the physical effects of alcohol can lead to serious problems.

  1. General Effects

    • Alcohol depresses the activities of the central nervous system, resulting in decreased blood pressure, heart rate and respiration rate, slow-responding pupils and skin that is cool to touch.

    Low Amounts

    • Low amounts of alcohol consumption can reduce tension, lower inhibitions, impair concentration, affect reflexes, and decrease reaction time and coordination.

    Moderate Amounts

    • Moderate amounts of alcohol can cause slurred speech, drowsiness, altered emotions, dizziness, increased aggression and anxiety.

    Large Amounts

    • Large amounts of alcohol can cause vomiting, breathing difficulties, unconsciousness, coma and death.

    Long-Term Effects

    • Excessive habitual drinking can lead to permanent damage to vital organs, cancer, brain damage, immune system disorders, addiction and death. According to the Centers for Disease Control, approximately 79,000 people die annually from excessive alcohol use (see Resources below).
