You need to use a saline solution nasal spray to keep your nose from drying out. You can get one at any drug store.\nYou might also try sleeping with a humidifier to keep the air in your room moist.\n\nIf that doesn't help, see your doctor and have your blood pressure checked.

the nose offactory glands produce mucuse to stop viruses and infections from entering your nasal passages. then promts you to sneeze the trapped particles out. If sneezing doesent work the cold sets in and to release the particles the nose begins to run. Dried mucus then clogs the nose completely however even before running you cant smell because the fine glands are covered first before the nose begins to run so you can breath but may not smell as good.

It may be a nocebo, everyone's nose either clogs or runs after crying, but if you relate it to allergies the nocebo effect kicks in and you THINK you are allergic to something, and thus you "are" :P

i was told its because the eyes start to water, and this gets the sinuses moving\n\nheres a blog with a lil more info..quoted..\n\n"The sudden exposure to bright light sends a signal through the optic nerve fibers. These fibers run close to and into the same hub as the trigeminal nerve. The second division of the trigeminal nerve supplies sensory fibers to the nasal mucosa. The assumption is that nerve impulses in the optic nerve cause a sympathetic discharge in the trigeminal nerve fibers. which produces the sneezing."

Because you need to drink more water? \n\nEight glasses a day to keep the dryness at bay!

that your eyes are dry, like cotton.  Probably the same as cottonmouth.

The sinus inside the nose builds up from the lack of warm oxygen. Thus, when you are in a cold area, you feel the clogging of your nose and eventually you will have snot.\n\nIf your nose is runny,\nAnd you think its funny,\nWell, it's snot.\n\n- ICE, Gaylord Palms FL

Have your parents take him to the doctor.  Why are you asking this question and not your parents?  He probably has blood vessels close the surface so everytime his nasal passages gets dry, or he picks his nose, he'll abrade one enough to make is bleed.

It bleeds because your nose is dry and has no moister in it. Just like any cut just apply pressure and after apply some Vaseline to it. That helps to prevent it.

nicotine is a stimulant, that's probally what's making your nose and tounge dry out.

Found some info hope it answers your question...\n\n\nMany people believe that if a dog has a cold, wet nose, he must be healthy. There is some truth to this old adage, but it is largely a myth. The true reason for the dog’s wet nose lies in basic physics. Dogs have very few sweat glands as compared to people. However, when a dog’s body temperature rises, it must still dissipate the excess heat. A dog uses his nose to relieve this buildup of body heat. Heat will escape through a dry nose, but a wet nose is more effective.\n\nHow does the nose get wet in the first place? Watch your dog; you will notice that every so often he licks his nose. A warm, dry nose simply means that your dog has been sleeping. When asleep, dogs don’t lick their noses!

This is due to your bodies own response to the allergens, dirt, and dust in the air.  The more that you are exposed to--the more your nose has to "evacuate" through the production of nasal secretions (i.e. boogers).  \n\nThere are little hairs in your  nose called cilia that gather all the dust and dirt etc. (sort of like being swept together like a broom) and these particles are what make up the secretions, along with mucous your body produces to lubricate your nasal passage.  If you have a cold or sinus infection, your body is working overtime to evacuate that from your body as well--hence, major boogers!! :<

Eye boogers are dried tears.  Tears have a great deal of salt and protein in them (think about how you have to clean contact lenses), so when the water evaporates as you sleep without blinking to clear the tears down your ducts, it leaves behind the salt and protein.

boogers are formed by drying out of nasal mucous.

Your nose and feet are NOT related. Your nose is running because it's allergy season. And your feet smell because you need to take a bath.

Along with what the others said on sinuses and the like, I'd like to point out that often cold weather accompanies dry weather. (as there is less H2O in the air when it's cold because of less evaporation and so on)\n\nSo, that air low in humidity may "dryen" the inside of your nose, wich is meant to be humid, thus causing pain and maybe even bleeding. The same as your lips get cracky and dry in winter time. \nAlso, the blood vessels in our inner nose tissue are somehow fragile. Breathing really really cold air may "burn" them by the cold a little, and thus the pain.\n\nI'm not an expert tough, but maybe a good scarf could improve things up! :)\n\nIn any ways, good luck with your problem! ^_^
