What happens when you consume caffeine?

Everybody knows a shot of caffeine can be a quick way to boost energy and stay awake.

But what’s really happening when you consume caffeine?

There’s some short-term benefits, along with some less-than-healthy side effects:

Short-term benefits of caffeine

When you drink a cup of coffee, gulp down an energy drink‌ or take a supplement with caffeine, the short-term benefits are what keep most people coming back for more.

Consuming caffeine in small amounts can: (4)

  • Increase alertness
  • Reduce fatigue
  • Improve reaction times
  • Decrease appetite and support weight management
  • Improve mood and decrease depression

Consuming too much caffeine can have negative effects on your health, too. This can include: (4)

  • Increased anxiety
  • Trouble sleeping
  • Elevated blood pressure
  • Dizziness
  • Dehydration
  • Digestive problems
  • Consuming high amounts of caffeine can even be fatal
  • Note: For pregnant women, consuming more than 200mg of caffeine per day can increase the risk for low-birth weight and other problems during pregnancy.

Here’s what caffeine withdrawal looks like:

If you’ve been used to a daily dose of caffeine, your body and your brain start to expect it. Remember, it’s an addictive stimulant.

And if you call it quits on caffeine without a gradual reduction, there’s a good chance you’ll go through withdrawal symptoms such as:

  • Irritability
  • Headaches
  • Depression
  • Fatigue

Fortunately, caffeine withdrawal symptoms are typically strongest the first few days after quitting. If you can make it through a week without caffeine, withdrawal symptoms typically subside.

6 Healthy Ways to Curb a Caffeine Addiction

Wondering how to curb your caffeine addiction to protect your health without major withdrawals?

Here are 6 healthy ways to curb caffeine cravings. (5)

  1. Track your caffeine consumption: Before you make any changes to the amount of caffeine you’re consuming, keep track of how much you’re consuming.
    • Remember, the U.S. Food and Drug Administration recommends limiting caffeine consumption to‌ or less than 400 mg per day.
    • Once you know what your caffeine intake looks like, you can create a plan to make some changes.
  2. Check food labels for caffeine content: Not sure how much caffeine is in your coffee, energy drink, chocolate, or supplements?
    • Read the food label. Many products made with caffeine include the amount of caffeine it contains in milligrams.
    • Can’t find it on the label? Chances are pretty good you can look up the caffeine content in drinks and products online, too.
  3. Cut back slowly:  If you want to lessen withdrawal symptoms associated with cutting back on caffeine, make your exit gradually. For example:
    • Drink one less cup of coffee per day.
    • Instead of an energy drink with high levels of caffeine, switch to a soda with less caffeine. Or only drink half an energy drink or soda.
  4. Drink more water: Before you gulp down a cup of coffee, energy drink, soda or other caffeine sources, make sure you’re drinking enough water.
    • For most adults, that’s around 64 ounces of water per day.
    • You may need more water if you exercise a lot, have a physically-demanding job, work in hot weather or live in a hot climate
    • Instead of supporting hydration, caffeine has the opposite effect of drinking water and increases dehydration and urination.
  5. Get your Zzzs:A lot of people reach for caffeinated drinks and supplements to combat tiredness and fatigue. But it’s really just a temporary fix if you’re not getting enough sleep.
    • Instead of relying on caffeine to get you through the day, get enough sleep. Here’s how:
    • Aim for 7 to 9 hours of sleep per night.
    • Create a bedtime routine
    • Turn of all electronics and screens about an hour before bed
    • Stay away from caffeine late in the afternoon or evening
    • Go to bed at the same time every night, even on weekends.
  6. Be more active: One recent study found that just 20 minutes of exercise has the same effect on mood, focus and memory as a cup of coffee. (6)
    • Start your day with 20 to 30 minutes of exercise.
    • Or if you’re feeling tired, take a walk instead of gulping down a caffeinated drink.
  7. Eat healthy foods: Skipping meals or eating sugary sweets and snacks can cause rapid changes in blood sugar levels.(6) This can impact mood and energy levels. Caffeine might be a quick fix, but there’s a better way:
    • Eat more nutrient-dense foods like fruits, vegetables, whole grains, nuts, seeds‌ and legumes
    • Whole and fresh foods take longer to digest and help regulate blood sugar levels better than sugary snacks and refined carbohydrates.
