Blood is *never* blue.  Blood is described as dark red (venous) or bright red (arterial).  Our veins look blue because we are looking at them *through* our skin.  The blood inside them is dark red and it doesn't reflect light very well. The blood you see when you get hurt is usually venous blood. oxygen-poor blood is blue, oxygen enriched blood is red.\n\nIn humans and other hemoglobin-using creatures, oxygenated blood is a bright red in its color. Deoxygenated blood is a darker shade of red, which can be seen during blood donation and when venous blood samples are taken. However, due to an optical effect caused by the way in which light penetrates through the skin, veins typically appear blue in color. This has led to a common misconception that before venous blood is exposed to air it is blue.

Hyperthermia. Hypothermia is the body being too cold, hyperthermia it is too hot.

Yes.  Sometimes the blood isn't very red at the beginning and the end.  Expect it to be weird before it gets regular- just keep supplies with you just in case and keep track of it.

Don't know which is strongest, but hot is fastest.\n\nYou can catch cold.

Cold. It's easier for me to get warmer in cold weather than it is to get cool in hot weather. I can't stand hot days.

Do you have a fever? If you have a fever go to the ER. This could be toxic shock syndrome, caused sometimes by IUD's. The IUD has a removal string henging into the vaginal area that can act like a conduit for bacteria to get into the uterus, from there, it can get into your blood stream and cause a serious blood infection. It might not be toxic shock, but it sounds very serious. Get checked.

Fever (also known as pyrexia, or a febrile response, and archaically known as ague) is a medical symptom that describes an increase in internal body temperature to levels that are above normal (37°C, 98.6°F). A fever is most accurately characterized as a temporary elevation in the body’s thermoregulatory set-point, which is usually by about 1-2°C. This elevation in thermoregulatory set-point means that the previous "normal body temperature" would be considered hypothermic. Effector mechanisms, such as increased blood pressure, increased heart rate, activation of brown adipose tissue, and muscular shivering attempt to counteract the perceived hypothermia, thereby reaching the new thermoregulatory set-point. It is the most common symptom of many diseases.\n\n\nSo now in simple word as the temperature of our body goes high our body start to react and water form the eyes is one of the effects.

Mine's gotta be ice - I absolutely love the cold! Fire doesn't really appeal to me (I hate the heat - even from a warm oven, or a burning fireplace). Besides, ice can be scuplted into different shapes (which just proves how incredibly versatile it is).\n\nFire on the other hand is just a flame licking all over the place, burning with passion and searing with heat.\n\nThat of course, is not to say that I'm a cold hearted guy with an icy stare. I just like the ice... =p

Your fever is your body fighting the infection. It raises it's temperature to kill the bacteria. When you feel cold, it's your body reacting to your fever trying to cool you down by giving you chills so you won't be uncomfortabley hot.

Sounds like you may have a sore throat that is causing the blood.  Try gargling with warm water with a little salt in it.

really cold. In the cold, you can at ;east attempt to get warm with layers and bodily heat. IN the heat unless you have air con, you can NEVER get cooled down

You could also be anemic.  Have a blood test done and check that out.

Hot or cold is relative to your body temperature. Something less will feel blah, cool, or cold depending on how much less. Vice versa for hot. The 'starting point' for hot or cold can be different for each person, or even for the same person, like if you just worked out, everything will seem a little warmer for a while.

All blood is red. Blood with oxygen has a lighter/brighter color, while blood without oxygen is more of a purpleish tint. It does not change color completely from blue to red. This is a common misconseption given from the fact that many charts use red and blue to show clearly which blood streams are which. The vein is greenish because of the many colors in your body combined. The skin, blood itself, and many other things contribute to this. I don't know about live veins, but I know the ones in stuff like meat are white, not green.
