Therefore our body tries to compensate by reducing fluid output. So your saliva production is reduced, your urine is more concentrated and you feel fatigued, dizzy, and suffer from dry throat and mouth. Furthermore, air humidification which happens in the lungs is also reduced due to lower body water content which aggravates the condition.

People who tend to breathe from their mouth instead of their nose tend to suffer from a dry throat. Habitual mouth breathers also tend to have similar problems.

Even over-the-counter drugs like antihistamines, antidepressants, opioids, and anticholinergics can have an adverse reaction on salivary flow rate.
  • Stress and Anxiety– Stress triggers adrenaline production that generally mimics the situation of danger. While in old times this necessary influence protected from animals and other dangers, with increasing workload has affected the salivary flow and digestion resulting in acidity, indigestion, constipation, dehydration, and dry throat.
