Most brain injuries are irreversible. Using bike helmets can reduce head injuries by up to 85 percent. In order to maximize the benefits of bicycle helmets, you need to make sure the helmet meets safety standards and is worn properly. A helmet should cover the top of the individuals forehead, be level from front to back and fit snugly. It should not rock back and forth or side to side when worn.
Many helmets come with removable foam pads to customize the fit.
The strap should be snug enough under the chin so that the bottom jaw is prevented from fully opening. New helmets are designed to have quicker release buckles, lighter weight, and greater ventilation for easier use. Surveys have shown that children know the dangers of head injury as a consequence of not wearing a bicycle helmet, however, they are still reluctant to wear bicycle helmets while bicycling. These children replied that helmets made them look like a geek, weird or dorky. They also complained that helmets made you sweat and were very tight.
