It might be something you've never considered doing - but if you've had your cycling helmet for a couple of years already, or if at any point you have the misfortune to fall off your bike, you should check your helmet.
Impact can weaken the structure and integrity of your helmet, and impair its ability to protect you.
If in doubt, splash out on a new one - don't risk a head injury. If it's an old helmet, you're probably overdue for a change anyway.
