Helmet Time

Your brain is fragile. Very fragile. Although it’s enclosed within a rigid skull, it is still vulnerable to injury. Whether the damage is due to a direct contact or an acceleration-deceleration injury, a helmet can protect the brain by adding in an extra layer for the head. In the event of a crash, a properly fit helmet could mean the difference between life and death.

The hard, smooth outer shell works to distribute the force across the helmet and protects the helmet against sharp, penetrating objects. The inner foam is made of impact absorbing material and is made to break so that your skull doesn’t have to! As the foam compresses, it absorbs the force of the impact and lessens the force that hits your skull.

The purpose of a helmet is to minimize the amount of force transferred to the head in the event of an impact. A helmet can reduce your risk of sports injury by 30 per cent. Whether you enjoy biking, boarding, or blading in the summer or skiing, skating and sledding in the winter, pick the right helmet for the job and always wear it.

There are two basic types of helmets: single-impact and multiple-impact. It’s important to select a helmet that fits you properly and that is appropriate to the activity you’re doing. Single-impact helmets should be replaced if EVER in a crash. If the foam breaks, it is not able to protect the skull for the next crash.

Make sure you use the right helmet for the job. The type of helmet you use should be dependent on which activity you are doing. Bicycle, skiing and snowboarding helmets are designed to protect your head against a single hard impact. They should be replaced after they’ve been in one crash, even if there does not appear to be any damage. Hockey helmets are designed to withstand several impacts. Unlike a bike helmet, ski, snowboarding and hockey helmets protect the back of the head — which is especially important for winter sports.

While it may be tempting to buy a second-hand helmet or use a hand-me-down, plastic becomes brittle and weakens with age. Make sure you know the answer to two questions:

            1. Has this helmet been in a crash?

            2. Is it more than five years old?

If the answer to either of these 2 questions is yes, then do NOT purchase or use this helmet.

Also, older helmets may not meet current safety standards. Look for safety certification by CSA (Canadian Standards Association), or CPSC (Consumer Products Safety Commission).

Proper fit is just as important as choosing the right helmet. It should comfortably touch your head all the way around, and be snug enough to stay firmly in place. Your helmet should sit level on your head and ride as low as possible to protect the sides of your head.
