When does salivary flow increase?

Explanation:
Salivary flow increases when you eat because tasting and chewing food triggers a reflex that activates the salivary glands. This parasympathetic response causes a rapid, watery secretion from the major glands (parotid, submandibular, and sublingual), producing saliva to help moisten food, begin digestion with enzymes, and protect teeth by buffering acids. Between meals, there’s less gustatory and mechanical stimulation, so the flow drops toward baseline. During sleep, reduced sensory input and autonomic activity further lower saliva production. So the notable increase happens at mealtimes, making that the best choice.
