At Rooted Table Café in Omaha, many of us love starting the day with a hot cup of coffee or tea. But have you ever wondered exactly what caffeine does inside your body? Caffeine can give you a quick energy boost, but it also has some downsides if you drink too much. Let’s explore both the good and the not-so-good sides of caffeine so you can make smart choices for your health.
What are the good effects of caffeine?
Caffeine can support your body in helpful ways when consumed in moderation.
1. Boosts energy and focus
Caffeine blocks a brain chemical called adenosine, which makes you feel sleepy. This is why coffee or tea can help you stay awake and alert.
2. Improves mood
Studies show that caffeine can increase dopamine, a feel-good chemical in the brain. This may explain why you feel happier after your morning cup.
3. Enhances physical performance
Athletes sometimes use caffeine before workouts. It helps muscles work more efficiently and may improve endurance.
4. Rich in antioxidants
Coffee and tea are natural sources of antioxidants. These support cell health and may reduce the risk of some diseases.
What are the bad effects of caffeine?
Drinking too much caffeine can cause problems, especially if your body is sensitive to it.
1. Sleep problems
Caffeine stays in your system for hours. Having it late in the day can make it hard to fall asleep.
2. Anxiety and jitters
High doses may cause shaking, a racing heart, or feelings of restlessness.
3. Stomach discomfort
Some people feel heartburn or upset stomach after strong coffee.
4. Dependence
Your body can get used to caffeine. Skipping it may lead to headaches, tiredness, or irritability.
How much caffeine is safe?
Most health experts suggest:
- Up to 400 mg per day (about 4 small cups of coffee) is safe for most healthy adults.
- Women who are pregnant and people with heart problems should aim for much less.
- Remember, caffeine is also found in tea, chocolate, energy drinks, and even some medicines.
