Hi it's me JOHEL REANG, iam starting my you tube channel for learning or to became a youtube and to show my talent. my you tube channel is about singing bollywood,kau bru song( COVER SONG).The endorphins which are released through singing will give you an immediate feeling of pleasure. And you can sing standing, sitting, and with good breathing technique, you can sing laying down. Group singing has been studied by researchers and shown that singers have lower levels of cortisol which lowers stress.
