How do bike helmets work?

Have you ever wondered how a bike helmet can protect your head from injuries during a fall or accident? Here’s the deal: bike helmets work by absorbing the force of an impact. The foam lining in the helmet is designed to crush and compress upon impact, spreading the force of the impact over a larger area and reducing the amount of force that reaches your head. This is why a bike helmet can look crushed or damaged after an accident – it’s doing its job of protecting your head! But did you know that bike helmets also work by redirecting forces? The shape of a bike helmet is designed to deflect some of the force of an impact away from your head, reducing the risk of serious injury. It’s amazing how something as seemingly simple as a bike helmet can save lives!
