when any human dieing what's his temperature,it does increases or decreases n why n how?

live human is "hot" because of all the 4 processes needed for the body to be alive.\nthe process generate heat as a by product of the reactions occurring .\n\nWhen animals are dead there are no more metabolic reactions to generate the heat so the temperature decreases.

Heat causes matter to expand, causing pressure to build in confined spaces.  So, if your blood pressure is already high and you increase the temperature of your body, it heats your blood, which is made mostly of water.  Water expands when heated and the limited space within your cardiovascular system is a confined space.  So the pressure builds.

Your body has mechanisms for cooling itself to regulate the internal temperature -- evaporation of sweat from your skin helps cool the body.\n\nIf your body temperature is unable to regulate itself, you end up with a heat injury -- either heat exhaustion or heat stroke.  Heat stroke can kill you.

Well, back in merry old England in the 1600s a relative of the king named Luke Huxtable died and was found in his bed a couple of hours after death by his daughter.  The body had begun to cool, but had not cooled off all the way.  He was "Luke warm."  The phrase was entered into common usage by coroners who, upon observing a body and checking for vital signs, would gauge the temperature of the body to determine how long the person had been dead.  For example: "Is the body cold?"  "No, but it's Luke warm, so he's been dead a couple of hours."

Very high levels of radiation will vaporize people.  High levels burn.  Medium levels cause changes in DNA, cancer, etc.  Low levels just tan you or keep you warm.

thats what would happen in a healthy individual because of peripheral vasodilatation.\n\nin sick people the vessels arent as elastic so the heart rate goes up, and the vessels calibre stays the same so their pressure goes up.

sundevil is right, it has to do with the ability of matter to conduct heat away from your body. Since your body is always generating heat by cellular respiration (your cells burning food in order to function), your body will increase in temperature if there is nothing to take away the energy, causing you to feel hot. Gases are poor conductors of heat, so they have to be much cooler than you to be effective coolants. Once you transfer some heat to the air near you, that air has to transfer heat to other air near it before it can absorb any more. Gas molecules are far apart and  transfer energy betwen each other much less than solids and liquids. Your body will keep making itself hot faster than the air can cool it down. Liquids and solids have much larger heat capacities, so they can absorb energy without much raising in temperature and are much better conductors of heat, transfering energy to other molecules so they can absorb more.

At too low a temp. an enzyme remains inactive.\n\nAt too high a temp. It is killed or ineffective or destroyed.

A newly dead human being, or any other animal, will sink when placed in water.  After the gases of decomposition build up in the chest and abdomen, however, the body will inflate, rise like a hydrogen-filled balloon, and pop to the surface, sometimes dragging with it surprisingly heavy weights that a murderer might have thought sufficient to keep it down.   With the passage of time and further decomposition, however, the body cavities eventually rupture, the gas escapes, and the corpse goes down again, this time for good.\n\nThere is one notable exception:  sometimes, due to air caught in the clothing, a body will stay on the surface for several hours before sinking.

Yes, for a very short time, because it can quickly lower your body temp.  If you wait too long you will develop hypothermia and possibly die

Newton's law of cooling deviates when there is a large temperature difference between the body and the surrounding (about 30 + degrees) .

When water temperature decreases, breathing should decrease as well. Breathing rate is correspondent to water temperature to fish because cooler water holds more oxygen than warmer water.

It's because of evaporation.  Whenever something evaporates, it takes energy away from what it's touching, and the temperature goes down.

Your body burns fuel to get the energy it needs to function. Just like any other combustion process, this generates heat. Since metabolism happens constantly, your body constantly generates heat.\n\nIn order to keep a constant temperature, your body has to balance heat production against heat loss. It turns out that this is easiest when the air temperature is less than your body temperature, since you will lose excess heat to the air. That's why around 75F (25C) tends to be comfortable for most people.\n\nIf the air temperature is the same as body temperature, you can only loose metablic heat through the evaporative cooling provided by sweating. This isn't as effective a process, so temperatures near body temperature aren't generally comfortable. \n\nIn fact, if the temperature is enough hotter than body temperature, sweating is no longer sufficient to maintain your internal temperature. As a result, the heat quickly becomes fatal.

No. There is no connection between high blood pressure and changes in body temperature. If you experience changes in body temperature, perhaps you have an infection that has nothing to do with your blood pressure.

There are several reasons body temperature can change quickly.  Hormonal upsets like hot flashes, lupus, illness/virus/infection/fever, thyroid malfunction all are causes.  Weather and exercise can also change temperature in the body.  Heatstroke and shock and make temperatures drop too.\n\nI would say, and I'm not a doctor, that you need to have a physical with a complete blood workup to test for thyroid, white blood count, lupus, and then go from there to see what the doctor thinks.
