How exactly does the the body produce body heat?
437677
the burning of sugar in your body to produce movement creates heat.  that's why you heat up faster when you exercise.

heat is the measurement of thermal energy

The average specific heat capacity of a human body is approximately 3500 J/kgK

At death, the human body is basically the same temperature that it was the instant before (when it was alive).  The body will then acclimate, just like any inanimate object, itself to the surrounding temperature over a period of time.

We generate heat through metabolic work, even when not physically working.  \nTo avoid increasing body temperature we need to dispose of this heat.  \nThis is clearly easier when the surrounds are cooler than the body. \nIt is still  possible even when surrounding temperature is above 98deg, as long as humidity is not so high as to prevent evaporation.

it does, but that is why we sweat to try and keep our temperatures down. and that is why if it gets to hot, and we dont keep ourselves cool, we can get heatstroke and some poeple die

When it's colder, your body must use more energy to maintain body temperature.  Exercise forces the entire body to warm up, so the answer is yes.  However, if your summer is hotter than body temperature, the body has to cool down; that process requires much much more energy.

http://en.wikipedia.org/wiki/Shivering\nShivering is a bodily function in response to cold in warm-blooded animals or the body's perception of cold. When the core temperature of the body drops, the shivering reflex is triggered. Muscle groups around the vital organs begin to shake in small movements in an attempt to create warmth by expending energy. Shivering can also be a response to a fever as a person may feel cold, though their core temperature is already elevated.\n\nOther responses observed in cold people (for example, swimmers emerging from a pool on a cold windy day), are dancing on the spot, hugging oneself with the arms surrounding the torso, huddling together, goose bumps on the skin, and using insulation such as towels.\n\nLocated in the dorsomedial portion of the hypothalamus near the wall of the third ventricle is an area called the primary motor center for shivering. This area is normally inhibited by signals from the heat center in the anterior hypothalamic-preoptic area but is excited by cold signals from the skin and spinal cord. Therefore, this center becomes activated when the body temperature falls even a fraction of a degree below a critical temperature level.

The human body sweats in order to regulate internal body temperatures, expending it in the form of water when the body is under great heat and pressure.

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.

In physics, heat is defined as energy in transit. Generally, heat is a form of energy associated with the motion of atoms, molecules and other particles which comprise matter. Heat can be created by chemical reactions (such as burning), nuclear reactions (such as fusion taking place inside the Sun), electromagnetic dissipation (as in electric stoves), or mechanical dissipation (such as friction). Heat can be transferred between objects by radiation, conduction and convection. Temperature, defined as the measure of an object to spontaneously give up energy, is used to indicate the level of elementary motion associated with heat. Heat can only be transferred between objects, or areas within an object, with different temperatures.

the immediate effects of heat applications is to draw blood away from the interior and bring it to the surface temporarily. A secondary more lasting effect occurs after the heat is discontinued, when the blood returns to the interior body. Heat increases circulation, metabolism,inflammation,decreases pain, muscle spasm,and tissue stiffness.

Energy (ATP, from the food we eat) in our body is used to create chemical energy so our body can move and proceed with its daily life.\n________\n\nAll I can think of :(  Hope this helps! :) :)

No, it is not loss of body heat. It has to do with the change in stimulation of the cilia and surface nerves in your rectum. Think about that loss of body heat idea... it doesn't really make sense. Let's say you have a cup of water at 100 degrees. Taking away any external factors, if you pour half of it out the water left in the cup is still 100 degrees.\n\nI should add that this phenomenon you're talking about is known as the "poop-shakes" and there is a theory that claims that people who have the "poop-shakes" (not everyone experiences them) are more likely to derive pleasure from anal sex.  Happy humping!

Body energy, necessary for breath, motion, heartbeat, thinking, and all that, comes from food. Chiefly from two components of food, in fact. Carbohydrates are made of carbon and hydrogen (sugars, starches, etc), and fats (oils) which are more complex shemically (butter, olive oil, etc).\n\nTo produce the energy cells need in the form they need it, to do their function, these are burned (in a clever and flameless way) indside the cell. The end products of complete oxidation are carbon dioxide and water. The oxygen necessary comes from air, through the lungs. \n\nThe more energy your muscles need (because of exercise) the more fuel is burned and the more carbon dioxide and water is produced. The carbon dioxide is exhaled (through the lungs) and the water is excreted by the kidneys. Both are carried by the blood from the muscles to the lungs or kidneys as needed. \n\nSo the more your exercise, the faster you breath and the more oxygen you take in and the more carbon dioxide you exhale. If you run for one hour, you'll produce a certain amount of carbon dioxide and if you run for 2 hours you'll produce just about twice as much. but, even if you're sleeping, you'll still produce carbon dioxide for many parts of your body still have to do some work even if you're not running around. Your heart still beats, your brain still works (dreams, maybe) and you still stay about the same temperature. All that takes energy, just not so much as you need when you're running. \n\nAnother source of carbon dioxide, a much bigger source than humans running around on a soccer field, or a baseball diamond, is burning fossil fuels. Gasoline, diesel fuel, coal, heating oil, ... all produce carbon dioxide and water (and heat) as exhaust products. All that carbon dioxide being put into the air is one of the causes, most people think the major cause, of the rise in average temperature on the Earth. This is the global warming that's been in the news.
