The autonomic nervous system is included in the peripheral system and is largely unconscious. It controls vital body functions such as heart rate, swallowing, breathing, digestion, and arousal.
The typical incubation period for a cold is 1-3 days. This means that it takes between 24 and 72 hours from the time you are exposed to the virus until you start to experience symptoms. Of course, this doesn't mean you will get sick every time you are exposed to a cold virus.
I be looking this stuff up because I wonder a lot about it. Right now for example, I feel the common cold might have more variables and stuff involved, including the incubation period. For example the chart lists 6-12 days for enterovirus, and 1-3 days for common cold.
