They are typically made from materials such as polycarbonate, fiberglass, or carbon fiber and are designed to absorb and dissipate impact energy.

8. Safety Standards: Many countries have established safety standards for helmets used in various activities, such as cycling, motorcycling, and snow sports. These standards define minimum requirements for helmet design, construction, and performance.

9. Brain Injury Prevention: Helmets are effective at reducing the risk of head injuries, including traumatic brain injuries, in the event of an accident or impact. Wearing a helmet can significantly decrease the severity of head injuries and improve the chances of survival.

10. Helmet Laws: Some jurisdictions have laws mandating the use of helmets in certain activities, such as cycling or riding a motorcycle. These laws are intended to promote safety and reduce the incidence of head injuries.
