Puberty is the time of your life when you grow into an adult. Generally it happens from when you're as young as ten, till you're 18. But it doesn't stop there; you continue to mature till your early 20's. But it doesn't all happen at once, lot's of different things change at different times. It is important to know about puberty so that you don't get all confused about whats happening to you.

Change in voice

During puberty personal hygiene is important. You might get lots of pimples on your face called acne. You will start to get body odour, and get really sweaty after doing sport. To help prevent this from happening, have a shower every day and after doing sport, and wear deodorant.
