Relationships are important for good emotional health. Numerous studies have shown that people who have close friends and intimate relationships are healthier, happier, and live longer. In fact, the simple act of petting a dog, holding a child, or seeing someone you love causes a decrease in stress hormones in the blood, decreases blood pressure, and calms the mind. So, if you want to be healthy, stay connected to others.
As the author Dr. Tedd Koren says "Emotional health is also dependent on being connected - to yourself and others. The more connected you are to yourself the more you can connect with others and the more fulfilling your connections (relationships). The more relationships in your life the more happiness, joy, hope, optimism and vitality you will have; the healthier and longer you will live and the quicker you will recover from physical and emotional traumas and illness."
