Simple Way to Decrease Risk of Concussions in American Football

Eliminating congratulatory helmet slaps is a no-cost, common-sense intervention with zero benefit and measurable subconcussive risk — yet it remains unaddressed in most concussion management protocols.

The Problem

Subconcussive Impacts

Impacts Add Up

College football players sustain up to 2,400 head impacts per season. New research shows that subconcussive impacts — those below the threshold for diagnosed concussion — can accumulate and contribute to CTE independently of diagnosed concussions.

CTE Risk

No Safe Minimum Threshold

About 20% of known CTE cases had no record of a diagnosed concussion. The disease is linked to exposure — how many hits and at what velocity — not just to concussion events. Helmet slaps add to that exposure for zero benefit.

The Solution

Recommendation

Eliminate all helmet slaps — congratulatory, celebratory, and punishment-based — at every level of football. This rule should be applied universally by coaches, players, staff, and parents. It requires only education, costs nothing, and removes a source of avoidable subconcussive exposure. A thorough 28-page concussion management protocol reviewed for this article contained no mention of helmet slap elimination — a significant gap.
