Why do it’s a must to put on a helmet while you’re skateboarding? – Artie, age 13, Queens, New York
Again when I used to be 13, I used to be an avid skateboarder – the kickflip used to be my go-to trick. And I didn’t see why I had to strap on a helmet earlier than working towards my ollies.
However now, doing the paintings I do, I am getting it.
My analysis is focused on working out how bodily forces purpose mind harm and find out how to perfect offer protection to in opposition to it. So I spend a large number of time eager about how the mind will get harm and find out how to reinforce helmets. This comprises paintings specializing in protective individuals of america army in coaching and energetic struggle zones.
So why is it so essential to put on a helmet when skateboarding, and likewise using your motorcycle, and in point of fact any recreation or task the place your head may just get harm?
Your very personal supercomputer
Inside of your head sits more than likely your maximum superb organ – your mind. It lets you do the whole lot you’re keen on, equivalent to tasting ice cream, looking at motion pictures, being attentive to track and, in fact, skateboarding.
Your mind is the sector’s mightiest supercomputer. The whole lot it does calls for billions of tiny mind cells, known as neurons, running in combination in unison. Those cells ship messages to the remainder of your frame that keep an eye on the whole lot from frame processes you’re no longer even conscious about – equivalent to your heartbeat – to shifting your muscular tissues, to serving to you assume and communicate.
Some researchers estimate that people have about 86 billion neurons, despite the fact that scientists are nonetheless running on discovering the precise quantity. That’s greater than 10 instances the collection of the entire other people dwelling on earth. They usually’re all filled inside of an area the dimensions of a melon, running in combination tirelessly, day in and time out.
In fact, your mind isn’t just made up of neurons. There are a large number of different cells supporting the neurons, together with astrocytes and microglia, which can be essential helper cells to the neurons.
However as busy as your mind cells are, they’re additionally extremely comfortable and squishy. If truth be told, your mind has the consistency of jello. And prefer jello, it is extremely susceptible, particularly to bodily forces, equivalent to a fall or a unexpected jolt.
The bodily forces of a fall
Now, you may well be pondering, doesn’t my cranium offer protection to my mind? And, sure, it does be offering some coverage. However your cranium is a layer of cortical bone simplest about .28 inches (7 millimeters) thick, making it an invaluable barrier that forestalls filth and different gadgets from coming into your mind, but it surely’s too skinny and too stiff to stay your mind secure in case of a fall whilst skateboarding.
Why is that? It is helping to damage down what occurs when your unprotected head hits the pavement: Upon affect, your cranium deforms, or adjustments form, and continuously rotates. However your cranium isn’t able to absolutely soaking up that affect. So the remainder power is transferred in the course of the arduous bone of your cranium and absorbed through your comfortable, squishy mind.
Consider squeezing and wiggling a block of jello to switch its form. That is very similar to what occurs on your mind: Just like the block of jello, when your cranium deforms, your mind will also be compressed and alter form. This may purpose your neurons to stretch and transfer in tactics they aren’t designed to, inflicting harm.
For this reason dressed in a helmet is so essential. In case you take a look at your helmet, you’ll see that it has two portions – an outer shell this is generally arduous and an interior shell liner, generally produced from stiff foam. The shell is supposed to give protection to your mind from penetrating gadgets. It additionally holds the lining, which is there to take in lots of the power from an affect so it doesn’t succeed in your mind.
Highway rash is curable, however mind accidents don’t heal simply – or every now and then in any respect.

Improving from a mind harm
In case you fall off your skateboard and also you’re no longer dressed in knee and wrist pads, it’s possible you’ll pores and skin your knee or ruin your wrist. However not like your pores and skin and bones, your mind doesn’t generally tend to heal simply.
With no helmet, a lot of the power out of your fall will get absorbed through your mind. Relying at the quantity of power that enters your mind, your mind cells will also be injured. Even a gentle aggravating mind harm, equivalent to a concussion, may cause vital harm to the cells inside of your mind. This might imply that you just lose a few of the ones mind cells or that they received’t paintings correctly anymore.
If too lots of your mind cells are broken or die, you could lose in point of fact essential mind purposes, equivalent to strolling, speaking or seeing obviously. The mind cells you might have now are in large part the similar ones you had while you have been born. And if you lose them, there is not any option to get them again.
While you lose mind cells, the remainder cells must paintings additional arduous to stay your mind serve as intact. Whilst trendy medication has gotten in point of fact just right at repairing lots of the tissues and organs on your frame, the mind continues to be a significant problem for researchers.
For this reason researchers like me spend such a lot time looking for tactics to give protection to the mind from trauma: A safe mind doesn’t wish to be healed. If truth be told, in step with one learn about of bicyclists, those that put on helmets are 65% to 88% much less more likely to get a mind harm.
So subsequent time you step onto your skateboard, needless to say you want your mind to do the entire superb issues it does for you, and do what you’ll be able to to give protection to it. Helmet on!
