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?
