Yes, it is possible for a person to die from riding a bike without wearing a helmet. While the use of a helmet significantly reduces the risk of severe head injuries, including fatal ones, not wearing a helmet increases the likelihood of sustaining a serious head injury in the event of a bicycle accident or collision.
Head injuries can be particularly dangerous because they can result in brain trauma, which can have severe consequences. Even a seemingly minor accident at low speeds can lead to a serious head injury if the person's head strikes a hard surface. The impact can cause skull fractures, brain hemorrhages, or other life-threatening injuries.
Wearing a helmet while riding a bike is strongly recommended as it provides a layer of protection for the head, reducing the risk and severity of head injuries. Helmets are designed to absorb and distribute the impact of a crash, protecting the skull and brain.
Therefore, it is always advisable to wear a helmet when riding a bike to minimize the risk of a potentially fatal head injury.
