In Vietnam, it’s common to see students with a can of Sting or Red Bull from a local store. These drinks promise a quick boost, especially before a tough exam or a late study session. While they are popular worldwide, many health experts are raising concerns. The question is: are these drinks a helpful study tool or a dangerous gamble for your health?

For a teenager facing a mountain of homework, this quick fix can seem very appealing.

Ensuring you get enough sleep, staying hydrated with water, and taking short, regular breaks during study sessions are far more effective. These natural methods support your body and brain without the dangerous side effects associated with energy drinks.
