(NaturalPath) A study published in PLOS Biology looked into why everyone acts the way they do when they are sick. Symptoms of sickness behavior (SB) include anorexia, hypersomnia, depression, and reduced social interactions. When you are sick there are physiological signs like fever and anemia, but there are also psychological ones like fatigue, depression, irritability, discomfort, pain, nausea, and loss of interest in food, drink, social interactions, and sex.

Interestingly, researchers find that variations of these symptoms are seen in a variety of species from arthropods to vertebrates and it doesn’t matter what kind of infection, whether a virus, bacteria or parasites.

One hypothesis is that we reduce our social interactions when we are sick out of an altruistic sense of not wanting to infect other people. Researchers think this extends to animals as well.
