Mornings are a time for new beginnings and fresh begins. And, according to the National Coffee Association, there is no better moment for that first taste of coffee at least for two-thirds of Americans.

Caffeine, in moderation, gives advantages such as improved alertness. There have even been studies that reveal possible heart health advantages including blood pressure reductions.

But, if this is your first cup of coffee, are you overdoing it? Too much caffeine, whether from coffee, soda, or dietary supplements, can cause jitters rather than a thrill.

Side effects of too much caffeine

  • Jitters
  • Shakiness
  • Anxiety
  • Fast heart rate
  • Nausea
  • Sleeplessness
  • Paranoia
  • Agitation

Because caffeine is a stimulant, it increases levels of serotonin and norepinephrine. In moderation, you can feel alert and acute euphoria. But if you overdo it, you’ll feel anxious and possibly sick

What has the most caffeine?

Coffee


Caffeine content in eight ounces of brewed coffee ranges between 80 and 100 milligrammes. While this may not appear to be much, the benefits might mount up if you consume more cups during the day.
Energy Drinks


Some popular kinds of energy drinks contain between 40 and 350 mg of caffeine per serving.

Tea


A cup of black tea has 30 to 50 milligrammes of caffeine. Other types, such as white or green tea, have less.
Soda


Although it contains less caffeine than a single cup of coffee, certain soda cans contain 30 to 55 mg of caffeine, depending on the variety.
Chocolate

Caffeine is commonly found in chocolate drinks, but don’t forget chocolate. A 100-gram bar of dark chocolate contains nearly the same amount of caffeine as a cup of coffee. Dark chocolate has more than milk or white chocolate, whereas chocolate-flavored items such as cakes, cookies, and brownies have less than actual chocolate.

How much caffeine is too much?

For healthy adults, the FDA has cited 400 milligrams a day that’s about four or five cups of coffee as an amount not generally associated with dangerous, negative effects. However, there is wide variation in both how sensitive people are to the effects of caffeine and how fast they metabolize it.
