Why cricketers chew gum while playing?

 I have observed many cricketers chew gum when playing.  Why do they do so ??

Just  day before yesterday,  Indian women's cricket team has won the ICC world cup !!!

But I am not sure whether women chew gum or not !!!

But men do.......     Because,

1.  Chewing gum stimulates the brain. It activates the receptors in mouth which in turn sends signal to brain that enhances brain activity and focus.

2.  Chewing gum produces saliva which helps to prevent dry mouth and keep it moist.

3.  Chewing gum can help players to keep calm under pressure.
