A few simple steps to avoid this:
A seawater-based nasal spray before bed;
steam inhalations or nasal washes;
an air humidifier to prevent drying of the mucous membranes;
a clear nose often means a dry pillow upon waking!
Too much saliva? Yes, it's possible…
Some people naturally produce more saliva than others. But this excessive saliva production can also be caused by:
Certain medications (such as antihistamines or antidepressants)
, gastroesophageal reflux (often subtle),
and meals that are too rich or too late
can all contribute to this. If you notice that this happens frequently, it might be helpful to consult a healthcare professional. There's nothing to worry about, but it's best to understand what your body is telling you (or "expressing" in this specific case).
