Whether you are biking or rollerblading or rock climbing or skateboarding, always be sure to wear a helmet when participating in dangerous activities. it may seem like an unnecessary precaution, but you should always wear a helmet no matter what. Helmets save many lives each year, and should be prioritized always.
The head and neck are quite vulnerable to impacts. Head and neck injuries can lead to concussions and fractures, as well as brain damage and even paralysis. Helmets are specifically designed to take the impact and deflect it, so that the head is protected. Head injuries are no laughing matter, and can get serious quite quickly.
The most common excuses for not wearing a helmet deal with it being cumbersome, it adding heat to the scenario, and not looking very good when worn. That being said, modern helmets have been updated so that they can be comfortable and aesthetically pleasing, while still being able to act in a protective capacity.
As such, everyone should wear a helmet for these types of sports, no matter what. It only takes a millisecond of bad luck in order to turn the day from fun to scary. Helmets should always be worn the right way, with the straps secured so that it remains in one place. Failing to wear the helmet in the correct fashion not only serves to make it less effective, but may even encourage the person to act even more recklessly than they otherwise would.
