Alcohol & You

Alcohol Facts

    • Blood Alcohol Level (BAC) measures the percentage of alcohol in a person's bloodstream
      • The amount you drink and the speed at which alcohol is consumed will have a huge impact on your BAC level
      • BAC = (alcohol consumed in grams) / (body weight in grams x R) x 100
        • Biological factors like a person's sex or size change the impact of each drink on a person's level of intoxication → R = 0.55 for females and 0.68 for males
    • Standard drink sizes:
      • Wine: 5oz = 148ml; alcohol by volume: 11-16%
      • Beer: 12oz = 355ml; alcohol by volume: 3-5%
      • Liquor: 1.5oz = 44ml; alcohol by volume: 40% (80 proof)
    • Water content in muscles dilutes the distribution of alcohol → greater muscle mass buffers a rapid rise in BAC
    • Drinking in an unfamiliar environment can increase your impairment (situational tolerance)
      • In a typical environment that you drink in, your body receives a cue that it will receive alcohol → tolerance goes into effect when cued
      • In an unfamiliar environment, your body does not get the cue → might feel like you drank more than you actually did

Strategies to Reduce Risk

    • Eat a meal before drinking
      • Food in your stomach can slow the absorption of alcohol
    • Pace yourself to 1 hr+ between drinks
    • Alternate with water or non-alcoholic drinks
      • Alcohol is dehydrating. Drinking water can help rehydrate + pace your drinks
    • Set a drink limit before you go out
    • Set your optimal buzz as your target level of intoxication
    • Group up - find friends who want to have a similar night as you
