Humor changes how patients behave. When we experience humor we talk more, make more eye contact with others, touch others, and we begin to feel better. Humor increases energy, and with increased energy, patients begin to perform physical activities that they might otherwise avoid. Humor can change a patient’s biochemical state by decreasing fms stress hormones and increasing infection fighting antibodies. It increases attentiveness, one’s heart rate and pulse. Without humor one’s thought processes are likely to become stuck and narrowly focused leading to increased emotional stress and fatigue. Lack of humor eliminates a healthy way for sufferers to feel better.
