How much coffee should I drink a day?

Answer:

Caffeine – which can be found in coffee, energy drinks, green tea, cocoa, and other drinks – enhances our wakefulness. Our digestive system quickly absorbs caffeine when we consume drinks containing this compound. Caffeine peak absorption occurs within 30-60 minutes after consumption, varying by individual.

Caffeine consumption can bring various benefits to health. However, excessive use of this compound can lead to insomnia, restlessness, and discomfort. Those who frequently consume a high amount of the compound may experience headaches, dizziness, nausea, and negative mood changes. These symptoms typically appear 12-24 hours after discontinuing caffeine intake.

According to the U.S. Food and Drug Administration (FDA), people should not consume more than 400 mg of caffeine a day if they want to avoid negative impacts on health. On average, a cup of coffee contains 70-100 mg of caffeine. Thus, an adult should not drink more than five cups per day.

You should also drink coffee at least six hours before bedtime. For example, if you usually sleep at 10 p.m., avoid consuming coffee or other caffeinated beverages after 4 p.m. to reduce the risk of insomnia.

Those sensitive to caffeine should be more cautious with their consumption of the compound. Certain health conditions also require people to consume less caffeine than the normal level. It is best to consult with a doctor for personalized advice on caffeine intake.
