Student doctor Robert Sithole delivers some insightful advice on the dangers of energy drinks, and alternative methods of staying alert.

The pressures and demands of medical school can be overwhelming. Long hours of studying, attending lectures, and participating in clinical rotations often leave me feeling drained and in need of a quick energy boost. It's no surprise that many of us turn to energy drinks, lured by the promise of enhanced alertness and stamina. However, the dangers associated with these popular beverages far outweigh their temporary benefits.
Energy drinks typically contain high levels of caffeine, sugar, and other stimulants, providing a quick jolt of energy. This might seem like a lifesaver during an all-night study session, but the reality is much more concerning. Consuming energy drinks can lead to a range of health problems, some of which can be quite serious.
First and foremost, the high caffeine content can cause significant heart issues. It can lead to increased heart rate and blood pressure, which, over time, may contribute to more severe conditions like irregular heartbeats or even heart attacks. As medical students, we should be particularly mindful of these risks, given our knowledge of the cardiovascular system.
Moreover, the excessive sugar in many energy drinks poses its own set of problems. A single can often contain more sugar than the daily recommended intake, contributing to weight gain and increasing the risk of developing type 2 diabetes. The sugar highs and crashes can also lead to erratic energy levels, making it harder to maintain consistent focus and productivity.
Another concern is dehydration. Caffeine is a diuretic, which means it can cause the body to lose water. This is particularly problematic when I’m already stressed and potentially not drinking enough water. Dehydration can worsen feelings of fatigue and hinder brain function, which is counterproductive when trying to study or perform well in exams.
Given these dangers, it’s crucial to consider healthier alternatives to maintain our energy and focus during demanding academic periods. Drinking plenty of water is one of the simplest and most effective ways to keep my energy levels up. Dehydration can lead to fatigue and difficulty concentrating, so I make sure to carry a water bottle with me at all times.
Choosing snacks that provide steady energy rather than quick spikes and crashes is also important. Nuts, seeds, fruits, and yogurt are excellent choices. They provide a mix of protein, healthy fats, and complex carbohydrates that help maintain stable blood sugar levels.
Physical activity is a natural energy booster. Even short bursts of exercise, like a brisk walk or a quick workout, can increase blood flow and oxygen to my brain, helping me feel more alert and focused. It might seem impossible with my schedule, but prioritising sleep is essential. I aim for 7-9 hours per night. Quality sleep improves memory and brain function, making my study sessions more effective. Techniques such as meditation, deep breathing exercises, and yoga can help reduce stress and improve my ability to focus.
Stress is a big energy drain, so managing it is key to maintaining overall well-being. Ensuring I get a well-rounded diet rich in vitamins, minerals, and nutrients is also crucial. Eating a variety of whole foods supports my body’s energy production processes.
A study conducted at a medical school revealed that about 60% of medical students reported consuming energy drinks at least once a month, with 30% admitting to weekly use. The main reasons cited were to stay alert during lectures, boost energy for late-night study sessions, and cope with the overall demands of the tough medical curriculum. This trend is concerning, given the known health risks associated with regular energy drink consumption.
By making these healthier choices, I can support my academic performance and overall health without relying on potentially harmful energy drinks. As future healthcare professionals, it’s our responsibility to model and promote healthy behaviours. After all, maintaining our well-being is crucial not just for our studies, but for the long careers that lie ahead of us.
