Coffee Drinking Caffeine overdose

Coffee accounts for 54% of the caffeine consumption in the world. Tea accounts for another 43%. On any given day, about 85% of Americans use caffeine products. The average daily consumption of caffeine by adults in the U.S. is about 300 mg per person. This is about three times higher than the world average. But it is still only half of the caffeine consumption in heavy tea-drinking countries such as England and Sweden.

Caffeine, the main ingredient in coffee, is usually considered to be an energy booster. Ingesting caffeine stimulates your central nervous system, which wakes you up and feels more energetic. But it can impact each of us differently, depending on our consumption habits and everyone's gene.

When you drink coffee, your stomach and small intestine absorbs the caffeine and redistributes it through your bloodstream to multiple parts of your body, including your brain. After caffeine reaches your brain, it sticks to your adenosine receptors. Now adenosine which makes one feel sleepy and controls sleep-wake cycle isn't produced and are being blocked and stopped by overdose of caffeine.

Drinking coffee sweetened with whipped cream, honey, syrup, or plain old sugar, might make you feel tired because sugar crash hits you. So as your blood glucose levels decrease, you feel a lack of energy that can tire you out. You may also feel hungry, irritable, anxious, sweaty, dizzy, or on edge as the sugar crash hits.

If you are regularly consuming coffee and stopping abruptly, you’re likely to feel the effects of caffeine withdrawal. You’re likely to feel the caffeine kick in as little as 10 minutes, and the amount of caffeine circulating in your blood peaks within 30 to 90 minutes after consumption.Sleepiness is one symptom of caffeine withdrawal, along with headaches, nausea, irritability, and an inability to concentrate.

At high doses, caffeine can produce these common side effects:

  • Diarrhea
  • Sweating
  • Nausea
  • Increased heart rate
  • Increased breathing rate
  • Muscle tremors

Withdrawal symptoms can occur when you stop taking caffeine after using it regularly for a long time.

These symptoms include:

  • Headaches
  • Sleepiness
  • Low energy levels
  • Bad moods

Drinking more water, exercising, and eating are all common recommendations for a mild caffeine overdose. Drinking herbal tea and practicing breathing exercises may also help you feel calmer.

How to Minimize the Negative Effects of Coffee

By following these steps, you can help prevent these negative effects from happening:

  • Limit coffee intake. The US Department of Health and Human Services states that you should consume no more than 2-4 cups of brewed coffee, or approximately, 400 mg per day.
  • Avoid coffee beverages that are high in sugar. Doing so will help keep glucose levels steady and prevent crashes later in the day.
  • Drink lots of water along with coffee. You can try alternating one cup of coffee with one cup of water. Watch for any signs of dehydration, such as cramps, thirst, or a dry mouth.
  • Avoid the afternoon crash. Switch to a drink with less caffeine in the afternoon. Tea makes a good choice.
  • Choose well-sourced coffee beans whenever possible. This will lessen your chances of coming in contact with harmful mycotoxins.
  • Listen to your body and make adjustments as needed. If you notice any unpleasant sensations after drinking coffee, try cutting back to see if it helps.
