Why do humans sometimes cough while asleep, but they never sneeze?
According to Dr.Fredric Neuman, in a recent post as his “Fighting Fear” blog in Psychology Today, it’s a matter of preservation.
Being a quiet sleeper may have protected early humans from nighttime predators. Imagine a saber-tooth tiger treading silently through woods when suddenly he hears and “achoo” from a nearby cave.
While sneezes originate in the nose, and you don’t need your nose to breathe. coughing is directly related to breathing and the need to breathe “trumps other considerations,” Neuman wrote.
“Therefore, sleeping is no cough preventative.” If natural selection weeded out the sneezing sleepers, why didn’t it do the same for snorers? It could be that snorers tend to be older people who are less likely to reproduce and thus, are less important to the survival of the species.
