Why use a helmet?
Helmets are useful as safety gear to prevent injuries in an uncontrolled environment. If you can't prevent a crash or impact, but you know it will occur, a helmet can prevent or minimize injury to the head and brain.
We can not emphasize enough that the first step in preventing injury is to minimize the probability of crashing or being impacted. Not hitting something hard is infinitely better than hitting with a helmet on!
There are many reasons for that statement. No helmet can protect against all possible impacts, and the impact may exceed the helmet's protection. No helmet protects any part of the body that it does not cover, so even if the head injury is avoided you may have a smushed face, broken bones or worse.
Safety always involves compromises. A helmet that could protect completely against every impact might be huge. A strong strap that keeps the helmet in place in a crash may strangle a child catching that helmet in the monkeybars on a playground. Helmets are designed to keep expected impacts within the range of human brain tolerance. But what if the brain is in a senior citizen and has become more brittle and less flexible, or what if it has already been injured in the past and is easier to re-injure? Or what if it is just more fragile than the average due to hereditary factors? Current helmet standards do not even attempt to address this problem. Concussions are reduced, but still acceptable as long as catastrophic injuries are reduced. Eliminating the crash or eliminating hard objects in the crash environment may be a more effective means of addressing a head injury problem than wearing a helmet. The benefits of that approach extend to those other parts of the body that a helmet does not even attempt to protect.
How does a helmet work?
Human brains can be injured by impact, of course, or by exceptionally violent rotation of the head, when the brain remains stationary, giving blood vessels and nerves a yank. Internal blood vessels and nerves yank parts of the brain around too in different ways, straining the vessels and nerves in the process.
Helmets designed to handle major crash energy generally contain a layer of crushable foam. When you crash and hit a hard surface, the foam part of a helmet crushes, controlling the crash energy and extending your head's stopping time by about six thousandths of a second (6 ms) to reduce the peak impact to the brain. Rotational forces and internal strains are likely to be reduced by the crushing.
In a lab test, graphs of the impact energy the brain sees look like this, with a smooth curve extending over 6ms for the good helmet
