Yummy mummies have long sworn by breathing slowly to relax at their weekly yoga sessions.
Now scientists have found the idea of slow breathing is not mumbo jumbo, but actually works in the brain to create a sense of calm. An experiment found mice became significantly more blissful after their breathing was slowed down. While breathing exercises have been used for hundreds of years, and prescribed to panic attack victims, it was not known how they worked.
Researchers led by Stanford University discovered the answer by accident after knocking out neurons in mouse brains which control breathing. A few days later, they noticed the animals, which were taking fewer fast, active breaths, were extraordinarily calm.
