Dear Doctor,

I am a sixteen-year-old student and I've been experiencing lots of back pain and headaches lately. I'm unsure about the cause. Like some of my friends, I spend my evenings playing computer games and surfing the internet. What's more, I carry a heavy schoolbag to school daily. I'm just an ordinary student, but these health problems are starting to worry me. What can I do?

Dear Adam,

I'm unable to tell you exactly what's wrong, but I can offer some advice. First of all, don't spend too much time on your computer, and stop using it late at night. It's important for teenagers to get enough sleep. Also, you get headaches from looking at computer screens for a long time. If you sit on a chair for long, it can make your back sore too. As for your schoolbag, it's important to manage its weight. Take anything you don't need out of your schoolbag. If possible, leave some books or materials at school.

I hope my advice is helpful. Anyway, I strongly recommend（推荐）you visit a local doctor for that.

Dr. Know
