Like a safety valve, humor offers a shift in perspective and energy that restores a sense of balance. It's okay to laugh again. It's good spiritually. It's good psychologically. Humor vents anger and despair, liberates hidden emotions, and promotes healing.
Laughter is good medically.
The Journal of the American Medical Association emphasizes the therapeutic value of humor. Laughter loosens muscles, enhances circulation and triggers the body's natural pain killers. It works without bad side effects. Your loved one is dead, but you're still alive. Smiling and enjoying parts of life is not an indication that you loved less.
