Perhaps the first question is ask why we cry. Without an extensive knowledge of the physiology one could make a guess that pain to areas of the face when confronted with natural irritants would favor those that could induce a flushing of both eyes and nose to clear irritant from face.
This evolutionary response to pain carried over to emotional pain when we evolved to have complex emotional response to feelings.
So the pain emotionally is exhibits the same response it did to protect us from irritants in nature with both eye and nose flushing out.The two reactions are so wired together in us over time they now are areactionary pair.In reverse , try to sniff an onion without crying also.
I am sure someone who studied anatomy can give the mechanics of how it happens.
But this is my best guess as to why evolutionary speaking.

∙ 14y agoThe eyes are connected to to nose through small tubes which drain away excess fluid in the eye. When you cry there is too much fluid filling up your eye so some overflows as tears and some drains into your nose making you feel like you have to blow.

∙ 12y agoYou really shouldn't, especially with any force or with holding one nostril closed while you blow. If you blow hard enough to make your ears pop, you could cause mucus to go back up into your sinus cavities, causing more irritations and possible infection. If wiping it doesn't satisfy and you HAVE to blow your nose, just blow gently and try not to put much pressure into it, i.e, don't blow so hard your ears pop.
Use of saline nasal spray to clear your nasal passages is recommended instead by most health care professionals in these situations. Follow the label directions for use. There are also nasal irrigations you can use for this, one brand with all needed equipment is called Netti Pot.
