Helmet Advice
Well, all helmets meet the same standards, and I don't think those
standards have changed since the "Which" article was written. The Which article noted a tendency for helmets that meet the European std not to meet the American standard, and vice versa, but some did meet both. The best rule is NOT to get a "good one". What makes a helmet "good" is usually being lighter and cooler than a cheap helmet. This is achieved by using as little styrofoam as possible, so an expensive helmet is probably even less protective than a cheap helmet, even though both meet the same stds. There is some question about whether it really is necessary to replace a helmet every x years as some people recommend. In practice the styrofoam is unlikely to degrade from UV radiation. However, one current theory about why helmets are so ineffective in practice is that they are not kept tightly enough in position. It might be, so the theory goes, that putting on and taking off a helmet over and over again gradually compresses the material inside, thus making the helmet loose. The same theory emphasizes that the chin strap MUST be kept tight. If you can open your mouth to talk, the strap is probably too loose. Adding a helmet to your head makes it larger and heavier than normal, thus upsetting your reflexes that move your head out of the way of impacts. Thus you will hit your head more with a helmet than you would without. This doesn't matter though, because of that very helmet. Don't assume, though, that in the impacts you are now having the helmet is saving your life. Jeremy Parker |
