Across the country many people have caffeine regularly as a part of their everyday routine. This usually comes in the form of coffee in the morning or throughout the day, however recently energy drinks have been on the rise. With the suggested limit of caffeine being around 400 mg a day, the rise of energy drinks containing up to 300mg of caffeine is cause for concern. A study on the health risks of energy drinks highlights the possibility of adverse effects on the cardiovascular system such as increased blood pressure and heart rate.
