Does your child often complain of being cold when you're not? Does he/she get the chills despite not being in a cool environment? This can be a sign of the kiddo experiencing high stress levels, which can cause the body to suddenly change temperature. Also, adults who have diagnosed anxiety attacks have reported bouts of the chills before a severe attack or, similarly, a tinging down their spines. When people are in the grips of a prolonged heightened level of stress, they may not even notice that they're sweating until the cold chills set in or their bodies begin to regulate once more.
