The Coffee Habit: Caffeine Craze
Before you start guzzling that whole pot of coffee however, its best to keep in mind that coffee is a drug whose overuse can have harmful repercussions on your overall health. Although antioxidant rich coffee does boost numerous health benefits including prevention of Parkinson’s disease and type-2 diabetes, you should be aware these facts:
- One 8-oz. cup of coffee can contain up to 200mg of caffeine, more than half of the daily recommend intake.
- Caffeine takes about 30-60 minutes to reach its peak concentration in the blood stream and its effects take four-to-six hours to wear off.
- While the harmful effects of caffeine vary depending on your tolerance and size, the generally accepted dose of 300-500mg (more than two 8-oz. cups) of caffeine can produce symptoms like jitters, increased heartbeat, nausea, anxiety, heart palpitations, insomnia, sweating, dizziness, vomiting, dehydration, muscle twitching, and then cardiac arrest.
- Instead of downing coffee for its stimulating effects, Maureen Geraghty, a registered dietitian and assistant professor in the School of Allied medical Professionals, recommends sleep and exercise ( even a brisk 15-20 minutes walk).
