Whether it's to fuel your late night study session, or trying to stay alert on the job
energy drinks are very popular with 76% of young adults consuming them, but what would
happen if you ONLY drank energy drinks?
One sip and the feel-good effect is almost immediate.
When the sugar molecules hit your taste buds, it triggers your brain to release dopamine,
the hormone responsible for feelings of happiness and well-being.
This makes sense, considering the sugar content of ONE can ranges from two teaspoons to a
whopping 14 teaspoons per serving depending on the brand.
Within 10 minutes, both your heart rate and blood pressure increase in response to adrenaline
release, caused by the introduction of caffeine into your body.
How much caffeine depends on the brand and ranges anywhere from 6 mg to as high as 242
mg per serving.
To compare, a serving of brewed coffee contains 95 to 165 mg of caffeine, brewed black tea
contains 25 to 38 mg, and a bottle of Coke contains 34 mg of caffeine.
But unlike soda, coffee and tea, energy drinks add in guarana extract.
The guarana plant which is native to South America, produces seeds which are about the
same size as a coffee bean, but yields twice the caffeine content.
Spread out over the course of a day 400mg of caffeine appears to be safe, but having
more than 200mg in a single sitting can lead to caffeine intoxication.
In 2011, it is estimated that nearly 20,000 visits to the emergency room in the United
States are directly related to the effects of energy drink consumption.
Most of these visits involved those between the ages of 18 to 25, and the second largest
age group being 26 to 39 years old.
So if you started subbing your 8 glasses of water for equivalent amounts of energy drinks,
the constant increases in heart rate and blood pressure might lead to an increased risk of
developing a bunch of cardiovascular conditions, including hypertension or high blood pressure.
An observational study reviewed 7 years of data from calls to Australian poison information centre
of the 297 calls analyzed the most common symptoms of caffeine toxicity included palpitations,
agitation, tremor and gastrointestinal upset.
Twenty one cases had signs of serious cardiac or neurological toxicity, including hallucinations,
seizures, arrhythmias or cardiac ischaemia, and at least 128 subjects required hospitalisation.
A cup of black coffee has fewer than 5 calories, but the high sugar content of
energy drinks means a calorie count of about 850 calories in 8 cups of Red Bull.
This increase your risk for obesity and developing Type 2 diabetes.
But some of the risks are unpredictable, such as a 26 year old man who drank at least two
cans of energy drinks daily for a decade.
With no prior significant health issues, he had a seizure and fell into a three day coma.
Doctors ultimately attributed this to chronic sleep deprivation and over-consumption of caffeine.
Overall, energy drinks are relatively safe for infrequent consumption, butttttt you may
not want to drink them on a regular basis.
