Cycling is NOT dangerous. Before that, nobody wore a helmet. AND they live to tell the tale for a very simple reason — riding a bicycle is not dangerous.

We need this so we can encourage people to get on bikes, become active and reduce the nations healthcare costs and increasing productivity including people getting out and living their lives.

Warning it does give graphic descriptions on the animal testing bike tom petrie helmets led to this understanding that one may find disturbing. Thank you for share bike tom petrie helmets informative article. Waiting for next article as i am a regular reader of this blog. A driving factor behind some of the confusion is that many nontechnical bike helmet trek conflate population level effects with individual level effects. What may true on average in a population, does not necessarily hold bike tom petrie helmets an individual basis.

For example, many researchers question whether biks use kids full face bike helmet make a population as a whole safer due to auxiliary issues that occur in tandem e. Estimating exactly how much a helmet will help is difficult because you cannot randomly assign helmet usages and full head bike helmets scenarios to people then measure the outcome.

The existence of sampling bias does is not evidence against the effectiveness of helmets as implied by the authorits only that the effect estimate may not be representative of the population of interest or that population the statistic applies to — e. helmefs

This is the problem with self-selection bike tom petrie helmets bias, it is not clear exactly what is being measured. Confounding the issue of whether or not a helmet is effective to an individual in a crash, we are mixing in behavioural changes i.

This is important consideration when looking at population averages i. Unfortunately, many authors try helmetd conflate these two separate issues. As a counter example, we know from clinical psychology that if we place a giant spike on the steering column of cars people will drive more safely and be involved in fewer accidents due to the change in risk profile.

Does this mean we should advocate for spikes on steering columns? The underlying fact is we are constantly computing risk profiles in our head. In a similar manner communities that have better cycling infrastructure the probability of a crash is lower, therefore the risk of head injury is lower oakley road bike helmets people adjust their behaviour uelmets bike tom petrie helmets wearing helmets e. This petie bike tom petrie helmets mean going without a helmet magically reduced their risk of head injury.

Concussions are often linked to rotational injuries caused by glancing blows. Helmets that are hard shelled and smooth i. Slip planes may also reduce the rates of neck injuries as it introduces more play into the system. The effectiveness of these is still up for debate because of the difficultly of measuring effectiveness in real world situations. Difficultly in measuring does not mean there is a lack of an effect. These types of articles really need to separate issues facing the individuals versus issues facing a society.

While there are good arguments NOT to mandate helmet laws, this does not mean helmets are not effective neon helmet an individual. You really need to assess your riding conditions, behaviour and likelihood of a crash. Bike tom petrie helmets one ever plans for a crash.

There are many other things that do have measurable, positive safety effects. Why not focus on those and drop the helmet nonsense?

This is just an idea that seems self-evidently true, like the idea that helmets are useful. What we do know, because these experiments have been done, is that placing cameras and other monitoring equipment in a car will make the driver extra well-behaved, but only for a few days. After that people get used to the situation and revert to unsafe driving. This is why the only reliable safety program is road design that, for example, forces drivers to slow down kids motorcycle backpack people are present or that physically separates traffic to reduce vehicle-vehicle crashes.

My point is that we may all have nice ideas, but we are humans an humans are flawed. We need to rely on real-world data. People do not ride bicycles are bike helmets safer emergency rooms, they ride them in cities, suburbs and rural areas.

Thus, the useful information comes from city-level or regional population studies, not studies that are limited to the subset of the risk-taking, unhealthy, or just plain unlucky people who find themselves in emergency rooms. Lack of statistical power, sampling bias, lurking and confounding factors are all things can obfuscate an effect making it hard to detect.

For example time is inextricably bike tom petrie helmets with the effect of bike tom petrie helmets. The control site is used to assess potential time effects. None of these helmet studies even have controls. The evidence is very tenuous. You cannot always apply population level effects to individuals called an ecological fallacyotherwise putting glasses on would make a person smarter.

Studies have shown people with glasses rate higher in intelligence measures. I think many of bike tom petrie helmets headsets for bike helmets trying to misapply the research bike tom petrie helmets favour of your political ideologies. I am personally in favour of more cycling infrastructures over helmet laws, but to imply that helmets have no beneficial effect for an individual is misleading at best.

Rider X, Thanks for the sharp critique of this post. I agree that this article mixes too many variables and makes too many inappropriate comparisons: As a lifelong cyclist 58 of my 64 yearsan LAB League Cycling Instructorand a user of hardshell styrofoam helmets sinceI can personally attest to their efficacy in protecting against severe brain injury.

I have survived three 3 major head-impact collisions thanks to wearing helmets on a regular basis. My neurologist agreed, saying I had probably saved tens of thousands of dollars in brain surgery by wearing them when: In all three cases I went down instantaneously and hard, hitting my head. I have been treated for epilepsy since the age of 8, but only road hazards or autos—never seizures—have caused collisions. I liken bike bike tom petrie helmets in the United States, where roadways and drivers are far less bike-friendly than they are in Europe, to buckling my seat belt whenever I am in a car.

Driving—like cycling— bike tom petrie helmets a relatively safe activity most of the time, but wearing a seatbelt prevents serious head injuries in the event of a collision. It may be that some day—probably after I leave this life, although I have been working since for that day to arrive far more quickly—our bike helmet for youth and streets will be both safer for people pedestrians, transit users, and cyclists of all ages and filled with far more bicycles than they are today.

Perhaps then our streets might be risk-free enough to make cycling without a helmet a rational bike tom petrie helmets. But until that day comes, simple prudence and common sense tell me it is smarter to wear a helmet whenever I ride than to go without one, just like wearing a seat belt is smart every bike tom petrie helmets I am in a car.
