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.
The typical common cold incubation period is from two to five days, but symptoms can appear in as little as ten hours after the virus first enters the nose.
