Body Temperature

The main organ producing heat in the body is liver ,

you can also increase heat production by making exercise or eating food , which in turns increases the rate of metabolism , and increasing the rate of metabolism in the body generates more heat.

Stimulant drugs increase alertness and heighten awareness. They work in an area of the brain called the reticular activating system (RAS), which lies in the brain stem. The RAS controls wakefulness by sending signals to the upper part of the brain (the cerebral cortex), which controls thought processes. Activity in the RAS is controlled by the balance of inhibitory chemicals, such as gamma ami Stimulant drugs increase alertness and heighten awareness. They work in an area of the brain called the reticular activating system (RAS), which lies in the brain stem. The RAS controls wakefulness by sending signals to the upper part of the brain (the cerebral cortex), which controls thought processes. Activity in the RAS is controlled by the balance of inhibitory chemicals, such as gamma aminobutyric acid (GABA), and excitatory chemicals, including noradrenaline. Stimulant drugs trigger the release of noradrenaline by the brain cells, increasing RAS activity and so increasing the 'thinking' activity of the cerebral cortex. The best-known stimulant drug is caffeine. We often drink coffee to stay awake or keep our brains going when we're tired. Other stimulants include amphetamines and similar drugs once used in slimming to control appetite, but now banned because of their side-effects. Stimulants are also used for narcolepsy (a condition of excessive sleepiness) and hyperactivity (it sounds paradoxical, but they can help to increase the attention span). The risks of stimulants are considerable and many are classified as controlled drugs. They're addictive and in the long term the brain becomes tolerant to them, so increasing doses are needed to have the same affect. They can cause palpitations, anxiety, hallucinations and seizures. During use, natural stimulant production slows, so if the drug is stopped there may be depression and lethargy.

The body functions well at 25 degrees Celsius. also our normal body temp. 98.6

An animal that maintains its body temperature within a narrow range even when the environmental temperature varies is a warm-blooded animal.

yes

Normal operating Temp is about 87C

Body has been at rest.

A tiger's (P. tigris) average body temperature is 37.5ºC or 99.5ºF.

Countries that use Celsius use it in their ovens.

The hypothalamus controls body temperature

Hair contribute to the effects of preserving body temperature.

Feet have no contribution in body temperature, other than expanding the surface area of your body, requiring excess energy requirements in re-warming the blood that returns from the extremities; just like hands

A thermometer is used to meusure your body temperature either it can be clinical thermometer or digital thermometer.

By getting so sick that your body raises its temperature to kill the sickness.

That would be considered a low-grade fever and is above normal, which is 98.6 F.

in a volccano

Body temperature is around 37 degrees Celsius.

Something that has hit the central nervous system could cause this.

Only in part--the brainstem is also involved and feedback mechanisms, like sweating. But yes, the blood vessels dilate to help cool the blood which then circulates and helps cool the core body temp.

you should be concerned when its about 104

Around 23 degrees centigrade.

Even with perfect temperature (85 degrees Fahrenheit) the wind may play havoc with your plans. Most times, it's the mental attitude of the participants that makes the day.

Scrub first, to get rid of the excess try skin, then body butter!

why the human body temperature always remains constant in normal person

Your brain recieves signals from your skin receptors that tells your brain that your temperature is too hot. You produce sweat from your sweat glands, which cools your body down. The hairs on your arms lie flat against your skin so that no hot air can be trapped there. Your capillaries that are near the surface of your skin dilate/get widen so that more blood can get to the surface and so that more heat can be lost.

No. Pyrogens act by increasing the temperature, but they do not change the set point in the thalamus.
