Why I’m done wearing a helmet

done helmet

I’m done wearing a bike helmet.

Now, don’t hold me to that. Maybe I’ll want one in the winter when the roads are icy. Maybe I’ll be required to wear one on a group ride. Maybe I’ll travel cross-country, planning to bike on deserted roads. But when it comes to casual riding, I’m done.

At the conference I attended last week, I mentioned, “I don’t wear a helmet, and I’m a public health professional,” to audible gasps and laughter. I invited people to ask me why later, and many of them did. I’ll share with you what I told them in just a moment, but let me preface this: I think the main problem around making an informed decision about whether to wear a helmet is hard because there isn’t great data around helmet use. Due to the confirmation bias, we’re all looking for information to back up the belief that we already have. Do your own research, use your own brain, and figure out what seems right and feels right for you.

It’s debatable whether helmets are effective.

A 1987 study of helmet use determined that helmets reduce the risk of serious injury by 85%. That’s a statistic you’ll still see all over the place. The problem is, that study was deeply flawed and has been refuted. Governmental agencies have stopped using this number due to issues with the study. Other more recent studies have investigated the question of helmet efficacy, and have found that the benefit is not nearly as high as we used to think. One well-done study that evaluated all the current studies out there (called a meta-analysis) found there to be no benefit to helmet use when you take into account all types of injuries. Helmets protect against certain kinds of injuries (those to the head) and increase the likelihood of other injuries (those to the neck). Any study about helmet use is very hard to do well. You can’t assign one group of people to use helmets and another group of people not to use them. All you can do is look at two groups of people and compare them. The people who wear helmets are likely more safety-conscious than those who don’t, which makes comparing the two groups very difficult and will make it appear that helmets are more protective than they actually are.

People will often put up photos on social media of obliterated helmets and say, “Holy crap, look at my helmet! It saved my life!” But helmets are not supposed to shatter. When a helmet protects your head from a serious injury, the styrofoam inside will be compressed and stay that way. Most of the pictures I’ve seen are of helmets that have broken apart. It’s likely that the helmet did not protect someone from a severe injury.

Most cyclists don’t die from independently falling off their bikes, 92% of cyclists die because they are hit by cars. Bike helmets only protect against certain types of injuries to certain parts of the head, and the evidence is not compelling that they even do that well.

Helmets don’t protect you against crashes

Helmets don’t protect you against crashes, in fact they might make crashes more likely. It’s inevitable that after a motorist-cyclists crash you’ll see every media article mention, “the cyclist was/wasn’t wearing a helmet.” It doesn’t matter if a drunk driver sideswiped the cyclist and broke both of their legs, the news report will say “the cyclist was/wasn’t wearing a helmet.” It’s as if people think that wearing a helmet will save you from crashing in the first place. It won’t.

There is some evidence that cars may pass cyclists closer if they are wearing a helmet. This makes intuitive sense to me as cyclists appear more aggressive and protected when wearing a helmet which may make drivers feel safer giving them less room to ride. Some of the most severe and dangerous motorist-cyclist crashes happen when the driver gets too close and the car sideswipes the bike. I want as much room as possible, thankyouverymuch.

Just because someone wears a helmet doesn’t mean they’re a safer cyclist. It seems like a lot of people use helmet use as a proxy for caring about safety, and that’s just not true. Learning safe riding skills, being visible, and being attentive are the things we all can do to prevent a crash.

Helmet use may deter people from biking

The most protective factor for biking is having more bikers on the road. When there are more cyclists on the road, drivers are more used to seeing cyclists out, and are more likely to be looking for them. However, if potential cyclists see everyone else in their community wearing helmets while riding a bike, it communicates that biking is a dangerous activity that requires special protective gear. Someone may be deterred from riding a bike because they think it’s risky. Someone else may be deterred from biking because they think they have to wear a helmet and they don’t want to mess up their hair. Many more motorists and pedestrians die in traffic collisions per year than do bicyclists. We don’t see them wearing helmets.

The bike share systems are good evidence of how important casual cycling is. In over 23 million trips on bike share bikes, there haven’t been any fatalities and only 40 people have been hurt. Most bikers on bike share bikes do not wear helmets. In fact, mandatory helmet laws make it incredibly difficult for cities to begin bike share systems, even though these systems successfully increase casual cycling and getting more people biking. The people riding these bikes are usually slower than other cyclists and the upright orientation of the bike share bikes may lend to a more casual style of cycling.

The benefits of biking much outweigh the risks

Biking is good for public health, it increases physical activity and reduces air pollution. The long-term benefits of cycling on health outweigh the slight risk involved. When you take into account the long-term health benefits, it’s much more dangerous not to get enough physical activity than it is to ride a bike. If not wanting to wear a helmet deters someone from riding a bike, that sucks, because biking is healthy and awesome.

It’s humanizing not to wear a helmet

I am a human. I have skin that can get bruised and a head that can get bashed in and blood that can gush out in the event that a car runs me over. I don’t want to hide my head behind a helmet, I want drivers to pass me on the street and see that I am a person, a human, just like them. I think of my bare head as a sign that says: I am a living creature who wants to keep living, so please don’t hit me.

I was just in Europe, in Barcelona and Amsterdam, where cycling is pervasive. Hardly anyone wears a helmet, and most people have upright handlebars. This orientation feels safer to me. It makes it easier to see my surroundings and encourages me to take my time, look around, and bike a little slower. Since I got home, I replaced my road bike’s drop handlebars with swept back bars, for a more upright riding position, and I stopped using the helmet.

Besides, it’s glorious to feel the wind in my hair.
