After a player experiences a concussion, what is the first step in management?

The first step in managing a concussion is to encourage the player to rest. Rest is crucial because it allows the brain to begin its recovery process after experiencing a concussion, which is essentially a form of mild traumatic brain injury. During recovery, it's important to avoid activities that can lead to further injury or exacerbate symptoms, such as physical exertion or cognitive stress.

This rest should include both physical rest and cognitive rest, meaning that the player should not only refrain from sports but also limit activities that require concentration and mental exertion, such as using electronic devices or engaging in complex tasks.

Encouraging rest is the foundational step before any further assessment or management can take place, such as checking symptoms or providing hydration. Addressing a concussion without first ensuring that the individual is resting could result in prolonging recovery or worsening the injury.
