Can't Use Helmets in the Sun????

I don't see where you inferred that. Frank impled that in the bit I've copied below: Hadron: Again : if your head were to hit a car door, a bonnet , a curb or a plain old wall, do you, or do you not think a helemt would be beneficial in this case. Frank: If I _were_ going to hit, _and_ if the impact were within the very weak capabilities of a bike helmet, it _might_ be beneficial.

No one is in the habit of banging their head on the ground, any more than auto drivers are in the habit of driving into walls or other vehicles at speed...but, clearly these things do happen and in both cases appropriate safety devices are routinely employed, though rarely needed. In my own case, in the last 15 years of regular cycling my head has impacted the ground on several occasions (mostly while mountain biking). In one case, I took a high-side fall at about 20 mph when my front tire got caught in a rain rut, and the impact to the left side of my head was hard enough to fracture the helmet's styrofoam structure. Since this was on a rock-strewn trail, I was most pleased that: a) I didn't suffer a concussion (presumably because the impact forces were appropriately absorbed by the helmet), and b) my scalp wasn't lacerated by the rocks (something that a cotton cap would not have prevented). FWIW, as a follicly challenged individual, the protection against lacerations is of particular importance to me.

I still don't see where you picked up anything about the relative merits of cotton caps, so again, I wonder where you inferred that?

They also happen to pedestrians, who also happen to get killed by them from time to time. Trips and falls kill ~350 folk under 75 in the UK every year, so how come helmets aren't appropriate safety devices for them? In my own case, in the last 15 years of regular cycling my head has impacted the ground on several occasions (mostly while mountain biking). My data specifically exclude MTBing and since it's an arena where people are doing deliberately tricky things as a recreation rather than just getting about on the roads it would be silly for me to try and persuade you they're pointless off road, but also for you to draw on MTB experience to say why you should wear one on. Ummm....we're talking about cycling here. You can argue against wearing helmets while walking in another group :-) Yes, I'm talking about cycling. I don't wear a helmet road cycling because it's not very dangerous. It is similarly dangerous to walking, which almost everyone does so it's a useful barometer of the degree to which protective clothing is considered appropriate.

And cyclists (at least roadgoing a to b cyclists) don't hit their heads against the ground that often, not particularly more than classes of people that feel no need to wear helmets, so why should cyclists feel the need? Gary, I wrote the first paragraph above. I did NOT write the second paragraph. And in any case, neither paragraph says what you claim. I think you need to slow down in your posting. No one is in the habit of banging their head on the ground, any more than auto drivers are in the habit of driving into walls or other vehicles at speed...but, clearly these things do happen and in both cases appropriate safety devices are routinely employed, though rarely needed. Auto drivers are not in the habit of smashing their skulls into the driver windows, or driver door frames, or B pillars, or roofs of their cars, or other hard objects. Yet these items cause the largest number of serious and fatal head injuries in America every year - despite safety devices like seat belts, air bags etc. The advertising industry has done a great job of selling massive vehicles with exploding cushions, pretending a person is practically invulnerable in such a thing. But such vehicles are still the number one source of HI fatalities, killing those people inside them. In other words, the impression created by the sellers is false. The advertising industry has also done a great job of convincing people that simple bike riding is a horrendous source of serious head injury. And they've convinced many people that a very flimsy hat makes cyclists practically invulnerable. But once again, the impression created by the sellers is false. Cycling is, very roughly, about as dangerous as motoring, even with a bareheaded cyclist and an air-bagged motorist. Neither is very bad. Putting a 14 mph helmet on the cyclist makes no detectable difference in that fact. What you've been made to believe is false. In my own case, in the last 15 years of regular cycling my head has impacted the ground on several occasions (mostly while mountain biking). If you're going to test your balancing skills and reflexes by bouncing along rocky trails, that's one thing. Don't extrapolate to folks who are riding on smooth roads. There is much more similarity in risk between a city pedestrian and a city cyclist (actually, the cyclist is much safer) than between an adventurous mountain biker and a city cyclist. - Frank Krygowski |

Umm...not meaning to rain on anybody's parade here, but the frequency at which I bang my head on the ground while cycling--at least when considering the potential finality of consequences--does qualify as a habit. I think its the topography of the consequences that counts. If you kill yourself once, it's an isolated incident. But kill yourself twice, and you go on record as being remarkably habitual. Same with head banging--a couple or few times is a nasty habit if ever there was one. Thus, over the decades, I've a demonstrated habit of banging my head on the ground. I admit it. And so I wear a helmet. Mykal Crooks |

... No one is in the habit of banging their head on the ground, any more than auto drivers are in the habit of driving into walls or other vehicles at speed...but, clearly these things do happen and in both cases appropriate safety devices are routinely employed, though rarely needed. Here's what we're getting at Gary - if you sit down on the ground and you strike your head against the ground by swinging your head at it then indeed a helmet will protect your head from such a injury better than a cotton cycling cap. Maybe you've missed the thousands of times we've said that helmets WILL probably protect you from minor injuries. But in the sort of accidents in which cyclists are seriously injured or killed the forces are so great that the helmet is maxed out and you might as well wear the cotton cap for all the good it does you. Now you might well say (and for the record most of us already assumed) that there is a small group of helmet wearers that would have JUST gotten a serious injury and the helmet reduced it to just a minor injury. That sounds VERY good and we looked very closely at the statistics. No kidding - we were actually hoping to see something. But it just isn't there. IF helmets are making a difference in any head injuries the statistical relevance is approaching zero. In my own case, in the last 15 years of regular cycling my head has impacted the ground on several occasions (mostly while mountain biking). In one case, I took a high-side fall at about 20 mph when my front tire got caught in a rain rut, and the impact to the left side of my head was hard enough to fracture the helmet's styrofoam structure. Since this was on a rock-strewn trail, I was most pleased that: a) I didn't suffer a concussion (presumably because the impact forces were appropriately absorbed by the helmet), and b) my scalp wasn't lacerated by the rocks (something that a cotton cap would not have prevented). FWIW, as a follicly challenged individual, the protection against lacerations is of particular importance to me. I've perhaps a silly question - why do you tell us that you needed a helmet instead of needing to learn to ride better? Is it that you prefer crashing and perhaps overpowering the little protection a helmet can offer and killing yourself because you are convinced that a helmet will save your life regardless? As for experiences - I crashed at high speed on motorcycles riding out in the desert perhaps over a hundred times. This was pretty much before safety helmets so most of these crashes were without a helmet and I struck my head a lot more than once. But I never hit my head harder than a knock because I knew I could be killed if I did and I rode so that crashes weren't so bad that I couldn't control my fall. Why does everyone pretend that it isn't possible to do this? Why are you pretending that you are unable to control your mountain bike in such a manner that you don't risk your life? |

Lest anyone misinterpret my attitude: I don't think that helmets are useless for absolutely everyone. I knew one young woman who was definitely accident prone. For example, I saw her fall off her bike while standing stock-still at a stop sign. I saw her fall while walking across a parking lot without her bike. I saw her fall while trying to load her bike into the trunk of her car. And I saw her quit riding for a long while because she'd broken her arm by falling when skiing. Some people will be on the tail end of the "normal curve." For people who fall frequently enough to call it a "habit," pehaps a helmet may be of value. But those folks should probably give consideration to learning how to preven falls! Then, consider something more robust, like an absolutely bottom of the line bike helmet, or (better) a motorcycle helmet. More ordinary people average hundreds of years of cycling, statistically speaking, between serious head injuries. Perhaps those people should just ride for, say, 100 years, _then_ purchase a helmet? ;-) - Frank Krygowski |

Over the decades I've banged mine quite a lot on open doors of kitchen cupboards. Drawn blood more than once. I don't wear a helmet to do the cooking, does that make me silly? Do you fly around your kitchen at 25, 35, 45 mph? And I've hit my head on the ground a few times running and jumping and cross country skiing too. Don't wear a helmet for those either. Nor does anyone else I see. Much slower speeds; much lower forces. (Not to mention much softer surface, at least for XC skiing.) |
