Cardiac Arrest on a Plate

I found an interesting article today in USA Today. It talks about a study that was done in Annals of Pharmacotherapy that links heart problems with caffeine consumption and energy drinks. It also mentions taurine as an additive in energy drinks that can be hard on your heart. The article states:

"Healthy adults who drank two cans a day of a popular energy drink experienced an increase in their blood pressure and heart rate, which was insignificant for healthy adults but could prove harmful to people with a heart-related condition."

The study found that participants heart rates were up 7.8% on the first day of the study and 11% on the seventh day. Participants blood pressure also increased 7%! So if you have heart problems or don't want any later it is wise to stay away from energy drinks and high amounts of caffeine.

Caffeine and Sleep

Many people these days are using caffeine as a substitute for their nightly ZZZ's. However studies have shown that substituting caffeine for sleep may not be the smartest way to go. A study done by the National Institute of Mental Health has shown that people who use caffeine to make up for lost sleep may suffer from impaired memory and motor learning.

The study compared 61 people who either took a nap or took a pill containing caffeine before the study. The results found that people who took a nap performed significantly better on word recall, perceptual learning, and finger tapping motor tasks.

Dr. Scmednic states that: "Such an impairment of performance runs counter to society's assumption that caffeine typically benefits cognitive performance. Apparent improvements with caffeine might actually reflect a relief from withdrawal symptoms. Just as no medicinal alternative to a good night's rest has been discovered, so too caffeine, the most common pharmacological intervention for sleepiness, may not be an adequate substitute for the memory enhancements of daytime sleep, either."

Also, here is a video about how caffeine may affect your sleeping habits:

Dr. Lawrence Epstein describes how caffeine works to promote
alertness, but can also inhibit restful sleep. This video was taken

How Much Caffeine is too Much?

I found a great article by the mayoclinic that gives some signs that you are drinking too much caffeine. In the article they state that nine out of ten Americans rely on caffeine to get rid of fatigue and get through the day. Here are some signs that you may be drinking too much caffeine:

• If you consume more than 500 to 600 mg of caffeine a day. This is equivalent to drinking about four to seven cups of coffee.
  
• If you are jittery during the day.
  
• If you are having trouble sleeping.
  
• If you experience heightened anxiety or restlessness.
• Flushed face
• Headaches
• Accelerated heartbeat
• Nausea

Why do People Drink Energy Drinks?

Energy drinks are readily available at virtually all retail stores that sell food or drinks. From gas stations to check outs at grocery stores, if you need an energy kick you won't have a problem finding it. So why are energy drinks so easily available and why do people drink them so much? Well the answer is simple. They are available because people buy them and people buy them to keep up with the hectic American lifestyle.

In a recent focus group that I conducted at Brigham Young University, most students drink energy drinks just to have enough energy to get through the day. When asked about what kinds of negative health affects they were familiar with they stated they had little or no knowledge about what high caffeine consumption can do to you. And that's not all. Participants were told that if they drink 3 energy drinks per week they are spending over $270 a month on energy drinks. When we asked these college students if money would be a motivating factor to forgo drinking energy drinks, they all said no.

So what would motivate people to change their ways?? Would it be scare tactics warning about the health hazards associated with energy drinks? Or would consumers have to fit more sleep into their schedules? Whatever it may be it is obvious that consumers need to become more educated and responsible for their own health.

Here are some interesting comparisons that I found from this website.
