The vagus nerve connects the brain to organs throughout the body, including the heart, lungs and intestines. Stimulating the nerve has been shown to change brain-wave patterns and prod the cells lining the intestinal tract to increase production of happiness hormones, helping you feel relaxed and cheerful. To give the vagus nerve a little TLC, simply splash cold water on your face–from your hairline to your chin–twice daily or do a quick cold water rinse toward the end of your shower.
One of the easiest ways to foster joy and good health: tailoring your clothes to your unique needs. When deciding what to wear, consider the radiant energy of the colors in your closet. Each one has an effect on your body, and color therapy has been used for centuries in the treatment of disease and injury. Anxious? Pick a blue top, which promotes tranquility and calmness. Sad? Add a pop of yellow. The sunny color has been shown to boost cheer. Grieving? Choose pink, which can help heal sadness and loss.
