Does It Really Make Sense To Wear A Helmet In Sport?

In cricket, batting helmets are now the norm for most levels of the game.  Former England captain Denis Amiss used to wear a reinforced skull-cap device, and the trend took off with World Series Cricket in the 1970s.  Helmets have certainly prevented many head injuries and given batsmen more freedom to hook at head-high deliveries, but critics argue that by allowing the batsman to take his eye off the ball, they have contributed to poor technique with the result of more blows to the head.

In the late 1990s Australian wicketkeeper Ian Healy started wearing a helmet when standing up to the great leg-spinner Shane Warne, to avoid being hit by the ball spitting viciously out of the rough on worn pitches.  

And the England and Wales Cricket Board have made wearing a helmet mandatory for under-18 batsmen at all levels of the game in the UK.

The faster you go, the more proficient you get- the more careless you become, the more accident prone you get. A helmet - meaning a really good one - not speaking about those cheap imitations of known and safety-proved brand names - will really protect your head in a crash. Without a helmet, likeliness to suffer brain-trauma increases tremendously. A brain-trauma will, in almost all cases, make your memory ability deteriorate, as an immediate effect after accident, and it is here to stay. This in turn will increase your risk to suffer from severe dementia in old age dramatically. So, be it biking, motor-biking, skiing or in-line-skating, wear that helmet!  Admittedly, the  most common cause of brain-damage are car-accidents.
But in sports like soccer, basket-ball and fighting, you are well off to wear that mouth-protector, which will soften the impact of a hard blow somewhat and may prevent you being concussed. Concussion can lead to the loss of one of your senses - like hearing or smelling.

Yeah it is cos it protects the most important organ in your body, the brain , in case of any crashes. Thats why they are called CRASH HELMETS.
