It’s easy to get completely addicted to coffee on Wall Street.When you start out as a young analyst, the boring hours between spreadsheets and pitch books are spent going on Starbucks runs.
And of course, everyone needs a pick-me-up working those 14 hour days.
You can drink too much coffee, however, and that can be harmful to your body. Research indicates that ingesting too much caffeine (500-600 mgs or 5 or more cups of coffee) can cause anything from restlessness to muscle tremors.
So keep all this in mind when you order your next double shot of espresso.
According to a study by the University of Melborune, coffee is 'the most commonly used psychoactive drug,' and drinking more than 5 cups a day can have you hearing things.
Researchers gave 92 subjects large amounts of coffee and then had them listen to white noise.
From The Daily Mail:
Professor Simon Crowe, of La Trobe University in Melbourne, said: 'We also told them that within the white noise there may be parts of the song White Christmas and if you hear it, press a button. We didn't include White Christmas in the white noise but found that more people who were very stressed and had high levels of caffeine thought they heard the song. The combination of caffeine and stress affect the likelihood of an individual experiencing a psychosis-like symptom.'
According to studies by the National Institute of Diabetes and Digestive and Kidney Diseases, while moderate amounts of coffee can help the liver to detoxify the body, too much can have to opposite effect and hinder your liver's function. This is especially true if you're taking high doses of common over-the-counter pain medication.
The shallow breathing caused by too much caffeine can stymie oxygen's flow to the brain, which in turn harms the decision making process.
This varies from person to person, depending on how well your body can process caffeine. Coffee has a 6 hour half life so it takes 24 hours to work its way through your system (on average).
That means coffee right before bed (like when you've been pulling an all-nighter) is no way to get good quality sleep. Studies show that it reduces valuable REM sleep time.
According to research done by Johns Hopkins University, caffeine only gives you that focused energy because it gets you over caffeine withdrawals in the first place.
John Hopkins researchers found that caffeine-related performance improvement is nonexistent without caffeine withdrawal. In essence, coming off caffeine reduces your cognitive performance and has a negative impact on your mood. The only way to get back to normal is to drink caffeine, and when you do drink it, you feel like it's taking you to new heights. In reality, the caffeine is just taking your performance back to normal for a short period.
The University of British Columbia did a study in which it gave 40 rats amphetamines and caffeine. The amphetamines made lazy rats work harder and hard working rats more lazy.
The coffee, on the other hand, did nothing for the slackers. It didn't do anything for the workers either.
