Bike Helmets: Stupid Hat or Essential Protection?

crosspostato da: https://piefed.social/post/741601

Few topics in cycling inspire as much controversy as helmets. Some people insist they’re essential, calling non-wearers reckless and invoking harsh and violent imagery: “enjoy your traumatic brain injury”. “You’ll regret it when you’re in a hospital with a feeding tube”. You hear suggestions of denying access to public healthcare. On the opposite end, helmet skeptics argue that they’re a distraction. I’ve actually heard people call them “magic hats” that “don’t offer significant protection (if any at all)”. Helmets dehumanize cyclists and send the wrong message. They’re dorky and uncool, rather than fashionable and European.

So what’s the truth about helmets?

  • Having used my helmet multiple times it’s fairly obvious to me they actually performa a useful function. As far as I’m concerned the only controversy is whether they should mandatory or not (and I don’t think they should). But otherwise, if you choose to wear one I think you ARE doing yourself a favor wearing one.

  • Grew up riding mountain bikes, skateboards (street) and snowboards 25+ years ago. I laughed at the snowboarders wearing helmets and told friends who were getting into the sport not to bother with them. Got married and my wife made me get a helmet (lame, but whatever), then I had some kids.

    8 years ago, I crashed snowboarding on an easy green run when going in for lunch. I was with a friend (rare for me as I usually went alone) and was taking it easy on an otherwise chill day. I ended up with two broken vertebrae, a tibial plateau fracture, a broken shoulder, and a concussion - i have no recollection of the accident, going down the hill in a sled on a backboard with patrol, taking an hours-long ambulance ride from the mountains, or any of my time in the ER - I apparently just kept repeating the same couple of lines to anyone I talked to, including my wife.

    I got back into biking a couple years ago and am now riding more than I ever did growing up - I avoid cars/paved roads and mostly ride gravel, single track, and multi-use paths now. I wear a helmet every time i go out. I went over the handlebars a week and a half ago while riding alone. I didn't hit my head - just a hard landing, some scrapes and a bruised ego - but just another reminder how quickly things can go bad and how little control over the situation you have when it does.

    A sweaty head and some random person thinking i don't look cool aren't really big concerns of mine (i also don't think I look very cool so I guess that makes two of us).

  • For me, the truth is I barely notice I’m wearing a helmet, and cars barely notice me as a cyclist even exists.

    So even if a helmet only does half of what it claims to do, I’ll take that chance in an accident with a giant metal box on the road.

  • I have seen far enough people died who could have survived if they wore a helmet. I rather keep wearing one. The same thing when in any two wheeled vehicle.

  • Studies in USA show automobile drivers perceive helmet less bicycle riders to be more dangerous so they give them more space. Therefore it is safer to not wear a helmet, up until the point your head makes contact with something. That said I always wear a helmet. Been hit by cars twice, twice cracked my "styrofoam hat" but not my skull.

  • Biking is safe whether or not you wear a helmet. The life-extending advantages of biking outpace the life-shortening risks either way. If wearing a helmet makes you more comfortable and you bike more, then that makes a bigger difference than the helmet itself.

    • Conclusions

      On average, the estimated health benefits of cycling were substantially larger than the risks relative to car driving for individuals shifting their mode of transport.

      https://pmc.ncbi.nlm.nih.gov/articles/PMC2920084/

      Even without a helmet, cycling is a safe, beneficial activity. Helmets offer significant protection if you fall off your bike or crash it (though much less if a car hits you) but the absolute rates of injury are small enough that this is a personal judgement call.

  • @lgsp I'm a fan of requiring them over 25kmph. Yes this is largely unenforcable, so no one will be fined. But it still gives the message that if you go fast you should wear one.

    But it also gets out of the way of people riding to the corner store for milk

  • This video is a great example of a seemingly simple topic having more nuance than you might expect.
