The brain, located in the skull in a dark segregated vault, has completely separated from the outside world; it depends on, the senses and neurology, which compose of the nervous system. To know what’s going on in the body’s environment, this nervous system is divided into two ways of perceiving the world. One emphasizes survival, called the “fight-or-flight” or “sympathetic nervous system”. The other is activated by safety called the “rest and digest” or “parasympathetic nervous system”.

Many of the markers of illness, including high blood pressure, anxiety, insomnia, suppressed immunity, skin diseases and digestive issues, as well as accelerated aging, have their basis in excessive sympathetic nervous system activity. Learning to activate the parasympathetic nervous system is an important strategy for enhancing well-being. Parasympathetic activity is initiated by slow deep rhythmic breathing, muscle relaxation and immersion in warm water.

The rest and digest neurology is also switched on by good feelings. Contentment, satisfaction, gratitude, laughter, spending quality time with friends and loved ones, petting and giving attention to a dog or cat or any pet can help. Even watching cute animal videos can generate a peaceful feeling and activate the parasympathetic nervous system for improved health and increased longevity.
