.The brain is the most important organ in the human body.It is in charge of absolutely all the functions that are performed. It is designed to think and anatomically protected by the bones of the skull and by the cerebrospinal fluid (which serves as a “shock absorber” against a blow).Imagine everything that happens when a boxer receives blows to the head, since a large percentage of them go directly to that area.It is inevitable that on many occasions there are consequences of some kind, especially in sight, speech and motor functions. The brain is made to develop absolutely all vital functions and repeated blows could leave some sequel.Although it is uncertain what damage the blows can cause in each of the boxers, it is unavoidable that they occur in many cases, since one of the main characteristics of boxing as a combat sport is “physical punishment” and therefore there will be consequences that usually appear in the long term.What is the best way to protect the brain from some kind of damage in boxing? The most important thing is always to seek advice from a health professional in case the fighter notices any anomaly or dysfunction in his way of thinking, reacting, speaking, seeing and even walking or performing any motor activity.It is also important to avoid or alleviate the damage that could occur with the following recommendations:The most important is to follow to the letter the regulations issued by commissions or organizations such as the World Boxing Council (WBC), where emphasis is placed on preserving the health and life of the fighter.This is done by following certain measures such as: not fighting when the doctor indicates it, after a certain time of having lost by KO or when the boxer feels sick.Also during training, make good use of protective equipment (mouth guard and mask). The referee also plays a vital role here: his performance in monitoring the prohibited blows and stopping the fights in time will be crucial.Have trained medical personnel for pre-fight, immediate and post-fight care, in case of emergencies.The other recommendation has to do with avoiding the use of prohibited substances in doping, since these types of substances often cause irregularities in the brain’s electrical function, in addition to altering the central nervous system (composed of neurons, sensory and motor) of the brain and spinal cord themselves that elicit the precise responses to the stimuli that the body receives.Finally, it is very important that the boxer is aware of the importance of having adequate eating habits and, above all, proper hydration, since the brain does not respond optimally in a state of poor nutrition and hydration. Being dehydrated, a boxer is diminished both physically and mentally and this puts him at a disadvantage. Reflexes, strength, reactions, attention, and concentration will probably fail in the ring and as the brain is dehydrated, he receives the blows in a more direct and forceful way as he is “dry” from the cerebrospinal fluid that protects him.Therefore, nutrition and hydration will be extremely important for the protection of the health of the boxer who goes up to fight in a ring.
