I understand it can be thicker for someone who isn’t hydrated enough. This question strictly refers to a healthy well hydrated individual.
Bonus question- what governs saliva to sometimes have bubbles and sometimes don’t?
In: Biology
Because it has stuff other than water in it. A whole bunch of electrolytes and importantly mucus, proteins and amino acids which have a variety of functions but also contribute to the viscosity significantly.
Re: bubbles. Not sure what you mean but it’s not coming out of your glands all bubbly, that would be down to what you’re doing with your mouth and how viscous and able to hold bubbles it is.
