The human body always works to remain in homeostasis. One form of homeostasis is thermoregulation. Body temperature varies in every individual, but the average internal temperature is 37.0 °C (98.6 °F). [1] Sufficient stress from extreme external temperature may cause injury or death if it exceeds the ability of the body to thermoregulate.
As in other mammals, human thermoregulation is an important aspect of homeostasis. In thermoregulation, body heat is generated mostly in the deep organs, especially the liver, brain, and heart, and in contraction of skeletal muscles. [1] Humans have been able to adapt to a great diversity of climates, including hot humid and hot arid.
Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries, even when the surrounding temperature is very different. A thermoconforming organism, by contrast, simply adopts the surrounding temperature as its own body temperature, thus avoiding the need for internal thermoregulation.
In humans, hyperthermia is defined as a temperature greater than 37.5–38.3 °C (99.5–100.9 °F), depending on the reference used, that occurs without a change in the body's temperature set point. [ 20 ] [ 21 ] The normal human body temperature can be as high as 37.7 °C (99.9 °F). [ 24 ]
About 70% of lotus for human consumption is produced in China. In 2005, the cultivation area in China was estimated at 300,000 hectares (740,000 acres). [28] A majority of lotus production takes place in managed farming systems in ponds or flooded fields like rice. [38] The most widely used system is crop rotation with rice and vegetables.
A new study finds that normal human body temperatures have dropped since the late 1800s. So what you think is normal may actually be a fever
Regional heterothermy describes organisms that are able to maintain different temperature "zones" in different regions of the body. This usually occurs in the limbs, and is made possible through the use of counter-current heat exchangers, such as the rete mirabile found in tuna and certain birds. [4]
Found across the regions of East Africa, India, Southeast Asia and Australia, there is much to be learned about the lotus flower and why it has maintained such a symbol across varying cultures ...
