19. Catching Infections
While there is no science that says that you will catch a cold from being out in cold or wet weather, but there is some science behind the idea that you catch a cold or the flu more often in cold climates. This is because the viruses can stay alive longer in the air, especially in low humidity areas. Since a baby’s immune system is not yet fully developed and their nose is generally dry this leads to a higher chance of infection. This is somewhat held off by baby immunizations and breastfeeding, but anyone in the household with the virus will have a higher chance of passing it on.
