The Glee actress, who recently hosted VH1's Do Something Awards, told The Huffington Post that she tries to focus her energy on local initiatives in California to provide help for those less fortunate.
Lynch explained: "I stay local with that kind of work. In California we're basically bankrupt in our public schools; we don't have arts, music or drama, so I help raise money for my own child's school so that we can have our art teacher and music teacher. I'm also part of a larger [organisation, in] that we do it for parents who don't have that kind of money.
"It's proven that part of your brain, when you wake that up, you're just a much more rounded person, you become a part of a team and you're making something beautiful, you're making something out of nothing - there's a lot to be said for that. It was a big part of my life, to go to choir."
Lynch also praised fellow celebrity George Clooney for his dedication to helping others, adding: "I love what George Clooney does, he gets right out there, he's helping a lot of people, he has many charitable arms, he puts his money where his mouth is and I'm impressed with that."
Lynch, who wed longtime partner Lara Embry in May 2010, recently revealed that she knew that she was gay at the age of 12.
She will host the 63rd Primetime Emmy Awards on September 18.
