when you get a bloody nose from heat. Where does the blood come from?

it comes from moving around. because of the heat you do not have enough mucous to keep it lubricated while in motion. Without that protection, the insides become brittle and subject to breakge. Much in the same way a hose on a car would become brittle with age and heat.

It means your picking your nose too much and you have a blood clot problem.

You should ask a doctor--a gastroenterologist told me that blood can come from a lot of places.  It could be a skin tear.  Usually, the brighter the blood, the closer to the surface the blood came from (I have also heard this).  In my case, I have IBS, and had to be put on medication.  Preparation H might help too.

they can cauterize your blood vessels in your nose, which will help prevent nosebleeds.  My brother gets them a lot, because we live in the desert, and the air is really dry.  One thing that helps is if you put a Q-tip into a jar of Vaseline (or maybe put Neosporin on it) and then swab the insides of your nose every morning and night.  It really helps.  I used to get nosebleeds a lot when I was on a medicine called Accutane (it dries your whole body out really bad -- it's for acne), and I used to do that.

Dry membranes in your nose.  we use a cool humidifier in our bedroom.  You can even get a bloody nose without scratching.  Dry skin.

Is it only during the night, or occasionally during daytime hours also? Sometimes this can happen at night if the humidity in the air is low. You're inside the house all night, and if the humidity is low, it can cause dryness inside the nose, which can lead to bleeding. I might suggest the use of a humidifier in each of their rooms as a test. You may want to run it only at night, since some windows (especially with wood trim), can be sensitive to absorbing humidity causing them to swell. Good luck!

Bruises, also known as contusions or ecchymoses, are what develop when your skin gets smashed for some reason but not broken. The soft tissues are damaged, the little vein or capillaries under your skin rupture and the blood puddles up under your skin. That's why a new bruise is red. It's all that nice red blood pooling up.\n\nEventually your body goes to work and starts metabolizing the spilled blood. After a couple of days, the bruise will look black or blue. By the sixth day, it goes all greenish on you, and then a few days later, it will turn sort of yellowish brown. It all has to do with the chemical changes involved in metabolizing that blood and getting things fixed up in there. \n\nAnd the reason that older people seem to bruise more easily is that their veins and capillaries and so forth grow more delicate with age and are more easily ruptured.  http://www.azcentral.com/news/columns/articles/0105clay05.html

There are a number of reasons why you might have had a different reaction this time.  Yes, the heat can be one, because your body may already be under stress from some of the effects of hot weather (possible dehydration and/or electrolyte imbalance due to perspiration).  Some people have difficulty breathing normally in hot weather, and they may feel dizzy or even more overheated.  Add any of these to the effects that giving blood generally has on your body (light-headedness, dizziness, etc.), and it may help to explain your reaction yesterday.

Well, blunt trauma contusions can be quite serious. How long ago did this happen? Do you have black eyes? Bloody nose? If any of these symptoms are present or this has going on for more than 5 days seek medical attention immediately.  \nDoes it hurt when this happens? If you were hit hard enough you may have suffered some sort of C-spine injury or inflamed disk. Give it a few more days then go see a doctor or ER. If you have any other questions my sn is Horseybabe1990 (yahoo). IM me if needed

Simple, bad blood goes from the heart to the lungs thru the pulmonary veins, and return to the heart already oxygenated thru the pulmonary arteries..☺

When our skin gets cut or injured, and it starts bleeding, 3 things happen in this order:\n1. Vaso-constriction: The vessels in the area constrict, to inhibit and decrease the output flow of blood.\n2. Platelets rush to the area, and start forming a platelet plug to further stop the flow.\n3. Coagulation happens (in healthy people) and you get a "blood clumping" or clotting. It is the body's way of stopping the bleeding.

S'not funny, is it? It's why most people get nose bleeds when they have colds, cos they bust blood vessels trying to get at stuff which isn't there.

The question should be: what did you change recently?\n\nThere are a couple of things that can have this temporary and usually innocuous effect...\n\nIf you've changed your diet or exercise routine recently. Changes in blood pressure could be responsible.\n\nAlso, altitude changes will almost certainly cause this. If you recently moved and your new location is significantly lower or higher then you may see significant blood from either nostril.\n\nMy advice would be to closely monitor the situation and if it doesn't clear up or gets significantly worse then see your doctor.\n\n--\nsf

You're nose becomes dehydrated and needs to stay moist. You will probably need to use some saline mist up your nose.

It could be an effect of the anesthesia or pain medications that you were given.  If this continues or if you develop a fever or any other strange symptoms like a rash or bruising, please see a doctor immediately!
