Why can my brother get so irritated so easily?

Name: Neel Date of Birth: 28th June 2001 Place of Birth: Bhopal Time of Birth: 10:05 AM

Recently, my brother has become irritated and angry about the slightest things. He screams, and then comes to regret it. We feel that he is pressured but it comes deeper like Garnet is unable to control his emotions. I have been wondering whether there is something in his chart indicating this - perhaps Mars or Saturn made in his temperament. I would like to know what he is so sensitive about and whether there is an astrological solution to enable him to be cool or not.
