A pet can be a person’s best friend, even when times are tough. Studies now show how having a pet as your friend can benefit your mental health and stress levels.

According to CNN Student News, people who are pet owners tend to have lower blood pressure and show signs of emotions improving. This is the result of less cortisol, a stress hormone, which is common in those with public anxiety. Researches also found individuals diagnosed with depression and severe anxiety who are pet owners have lower levels of cortisol and show signs of mood improvement.

“My dog Arthur is my best friend,” English teacher Keli Jacobs said. “He totally understands when I start getting upset. I don’t have to cry or yell or anything, even if my heart rate increases he comes to my side.”

Often pet therapy is the number one cure for depression and PTSD. The University of California-Los Angeles recently discovered pet therapy reduces rising blood levels and anxiety in retired veterans. From teachers to retired veterans, everyone needs a little love.
