Sickness behavior is a coordinated set of adaptive behavioral changes that develop in ill individuals during the course of an infection. They usually (but not necessarily) accompany fever and aid survival. Such illness responses include lethargy, depression, anxiety, loss of appetite, sleepiness, hyperalgesia, reduction in grooming and failure to concentrate. Sickness behavior is a motivational state that reorganizes the organism's priorities to cope with infectious pathogens. It has been suggested as relevant to understanding depression, and some aspects of the suffering that occurs in cancer.

Famous quotes containing the words sickness and/or behavior:
“The sickness of our times for me has been just this damn thing that everything has been getting smaller and smaller and less and less important, that the romantic spirit has dried up, that there is no shame today.... We’re all getting so mean and small and petty and ridiculous, and we all live under the threat of extermination.”
—Norman Mailer (b. 1923)
“Our first line of defense in raising children with values is modeling good behavior ourselves. This is critical. How will our kids learn tolerance for others if our hearts are filled with hate? Learn compassion if we are indifferent? Perceive academics as important if soccer practice is a higher priority than homework?”
—Fred G. Gosman (20th century)
