We sneeze when some foreign object like an irritant snuff powderor mosquito obstructs our nasal passage. A seeze is nature's way of explosively ridding the nasal passage clear of the irritant.
We yawn when the level of oxygen in our blood (which also circulates into the brain) gradually drops to a low level.
Predictably, our concentration during studies wavers, we feel sleepy, By yawning, we forcefully take in an extra breath of air to make up the shortage.
Even animals yawn--- for the same purpose.

Sneezing is caused by any obstruction in the nasal cavity (especially when it occurs between the tip of the nose and between eyebrows).
Yawning indicates lack of rest and inadequate oxygen levels in your system. You exhaust ozyegen when you exert. So deep breathing with good quality rest is the solution.

Sneeze because something is stuck - involuntary and natural instinct to take out the foreign body from the system.
Yawn is an involuntary and natural system which is the outcome of boredom.

we sneeze if something like a particle of dust is in our nose and we must get rid of it
we yawn when our brain needs oxygen, that is why we often yawn when we're tired.

Philosophically speaking...we yawn to take in more oxygen, we sneeze when something irritates our nasal passages, and that is my philosopy

All living things do these things. An automatic balancing of nervous system, a method like safety valves.
