Many people assume they’re sober after a few hours. Doctors say the reality is often very different.

Summer is peak season for backyard barbecues, pool parties, beach trips, concerts, and weddings. While enjoying a drink with friends is common, many people underestimate how long alcohol can remain in their system.

One of the biggest myths about drinking is that if you stop consuming alcohol for a few hours, you’re automatically sober. In reality, alcohol can stay in your body much longer than many people realize.

What Counts as One Drink?

Before discussing how long alcohol stays in your system, it’s important to understand what actually counts as a standard drink.

🍺 Beer: 12 ounces

🍷 Wine: 5 ounces

🥃 Liquor: 1.5 ounces (one shot)

While these contain roughly the same amount of alcohol, many cocktails contain more than one serving.

Popular Summer Drinks: How Many Drinks Are You Really Having?

Many people order a cocktail and count it as “one drink.” Depending on the recipe, that may not be accurate.

DrinkApproximate Standard Drinks
Beer1
Hard Seltzer1
Glass of Wine1
Margarita1.5–2
Mojito1–2
Sangria1–2
Mai Tai2–3
Long Island Iced Tea3–4

That means two Long Island Iced Teas could contain the alcohol equivalent of six to eight standard drinks.

How Long Does Alcohol Stay in Your System?

A common rule of thumb is that the body processes about one standard drink per hour.

That doesn’t mean you’ll be completely sober after exactly one hour. Factors such as body weight, sex, medications, food intake, age, and overall health can affect how alcohol impacts you.

However, here’s a simple example:

If you have:

  • 2 drinks, it may take 2+ hours to process
  • 4 drinks, it may take 4+ hours to process
  • 6 drinks, it may take 6+ hours to process
  • 8 drinks, it may take 8+ hours to process

This is one reason some people may still have alcohol in their system the next morning, even if they feel fine.

Alcohol Facts Most Adults Don’t Know

✅ Alcohol can begin affecting your brain within minutes.

✅ Feeling sober does not necessarily mean your blood alcohol level is back to zero.

✅ Coffee does not sober you up.

✅ Cold showers do not sober you up.

✅ Drinking water helps with hydration but does not remove alcohol from your bloodstream.

✅ Sleeping can help you feel more rested, but it does not instantly eliminate alcohol from your body.

Why Summer Drinking Can Be Riskier

Alcohol can be especially problematic during hot weather.

Dehydration

Alcohol increases fluid loss, and high temperatures can make dehydration happen faster.

Swimming Risks

Alcohol can impair coordination, judgment, and reaction time around pools, lakes, rivers, and the ocean.

Boating Accidents

Operating a boat while impaired can be just as dangerous as driving a car while impaired.

Heat Illness

Combining alcohol with prolonged sun exposure may increase the risk of heat exhaustion and heat-related illness.

Doctor-Recommended Tips for Drinking Responsibly

  • Eat before you start drinking.
  • Alternate alcoholic beverages with water.
  • Avoid binge drinking.
  • Know how much alcohol is actually in your drink.
  • Plan transportation before the first drink.
  • Never assume you’re sober simply because a few hours have passed.

The Bottom Line

The biggest mistake many people make isn’t having a drink—it’s assuming the alcohol is gone when it isn’t.

Whether you’re heading to a summer concert, rooftop party, beach day, or backyard barbecue, understanding how long alcohol stays in your system can help you make safer decisions for yourself and everyone around you.
