When you're nervous/stressed, your body releases various hormones which stimulate your autonomic nervous system (ANS)- commonly known as the 'fight or flight' response!. The ANS controls both the sympathetic and parasympathetic nervous systems - in the stress response, the sympathetic NS is switched on, and the parasympathetic is switched off!.

This response works with your sympathetic nervous system to:
-tell your adrenal glands release adrenaline/epinephrine (which in turn increases the amount of sugar and fatty acids in your blood, giving you more energy available)
-increase breathing rate
-increase heart rate
-increase blood pressure

This all goes to provide more blood (containing more oxygen and energy) to your brain and muscles, putting you in a state of readiness to either face or flee from the perceived danger!.

The response also switches off your parasympathetic nervous system; the system that controls glands (inc saliva glands) and smooth muscle!. This includes the control of "salivation, lacrimation, urination, digestion and defecation" - in short: drooling, crying, peeing, digesting and pooing!. All of these functions are temporarily put on hold, so the energy required for these tasks can be used by your mind and muscles for fight or flight!.

In conclusion: your mouth goes dry when you're nervous because you're stressed!Www@Answer-Health@Com
