Energy drinks are considered bad for health primarily due to their high caffeine and sugar content, as well as other stimulants and additives that can cause various adverse effects. These include elevated heart rate, high blood pressure, heart rhythm disturbances (arrhythmias), palpitations, and increased risk of serious cardiovascular events like stroke and cardiac arrest, especially in people with pre-existing heart conditions or those who consume them excessively. Additionally, the combination of caffeine and sugar can lead to a temporary burst of energy followed by a crash, causing fatigue and over time may contribute to insulin resistance, weight gain, and diabetes risk. Other side effects include nervousness, insomnia, headaches, tremors, digestive upset, and dehydration. Children, teenagers, and people with medical conditions are particularly vulnerable to these effects. The lack of strict regulation on energy drinks and reports linking their consumption to severe health incidents further raise concerns about their safety with frequent or high intake.
