How to practice Head protection
Always use a helmet that fits snugly and meets safety standards. Buckle your seatbelt every time. Avoid repeated head impacts whenever possible; the damage is cumulative even if symptoms fade.
The evidence behind Head protection
Head trauma is one of the clearest proven causes of later cognitive decline. A single moderate concussion can double dementia risk, and repeated minor impacts , as in football, boxing, or military service , raise the chance of chronic traumatic encephalopathy (CTE). Brain scans show permanent neuron loss after repetitive hits. Prevention is the only true treatment.
