question: If we increased the temperature of water every time our body got used to it, how high could it go?
comment: Just because the body gets used to it, doesnt mean its good for you. If you are in hot water too long, even if it feels fine, it can damage you. So you can put it as high as you will get before your body shuts down. Besides, eventually you will reach a temperature that you just wont get used to.
passages: For example, "Crocodylus porosus", or estuarine crocodiles, were found to increase swimming speed from 15 °C to 23 °C and then to have peak swimming speed from 23 °C to 33 °C. However, performance began to decline as temperature rose beyond that point, showing a limit to the range of temperatures at which this species could ideally perform.

   To cope with low temperatures, some fish have developed the ability to remain functional even when the water temperature is below freezing; some use natural antifreeze or antifreeze proteins to resist ice crystal formation in their tissues. Amphibians and reptiles cope with heat loss by evaporative cooling and behavioral adaptations. An example of behavioral adaptation is that of a lizard lying in the sun on a hot rock in order to heat through radiation and conduction.

   A 2010 study concluded that under a worst-case scenario for global warming with temperatures higher than 2007, the wet-bulb temperature limit for humans could be exceeded around much of the world in future centuries. A 2015 study concluded that parts of the globe could become uninhabitable. An example of the threshold at which the human body is no longer able to cool itself and begins to overheat is a humidity level of 50% and a high heat of , as this would indicate a wet-bulb temperature of .

  As hypothermia progresses, symptoms include: mental status changes such as amnesia, confusion, slurred speech, decreased reflexes, and loss of fine motor skills.

  As the temperature decreases, further physiological systems falter and heart rate, respiratory rate, and blood pressure all decrease. This results in an expected heart rate in the 30s at a temperature of .
   A Hothouse climate state refers to higher average global temperatures reached in Earth's geologic record, such as during the Paleocene–Eocene Thermal Maximum. A 2018 study concluded that we soon could cross a temperature threshold that would initiate self-reinforcing feedbacks, leading to an additional temperature rise not seen for at least 1.2 million years. The BBC cites the researcher as saying, "The climate might stabilize with 4-5 degrees C of warming above the pre-industrial age. Thanks to the melting of ice sheets, the seas could be 10-60 metres higher than now. Essentially, this would mean that some parts of the Earth would become uninhabitable." The study tries to answer where exactly this temperature threshold is, suggesting that it could be below the 2 °C temperature target agreed upon by the Paris climate deal, with risks increasing sharply at higher temperatures.
   This was later standardised at 68 °F and then 20 °C. This temperature may be significantly different from the temperature of the natural environment of the water being tested.

  Max returned to his school, and his teacher told him that he missed out on the excitement—the whole world had been frozen. Max explained why he was late and had to go into detention.
  
  After detention, Max saw the news on Newspapers and TV. One report said Tortoise Man's ray slowed things down.
   In the isopod's natural habitat the thermal waters ranged in temperature from . In 1947, when the spring was diverted to supply the city of Socorro with drinking water, the isopods ended up living in an old water supply pipe that led to a horse trough and two small, old, concrete bathing pools. In 1988, the wild population became extinct, when a tree root burst the pipe and cut off water flow to the concrete pools. Existing captive populations were bred to restore the isopod community near the spring and they were reintroduced, into eight new concrete pools (tanks). As of 2006, captive populations are kept at the Albuquerque Biological Park, the Minnesota Zoo, the New Mexico Department of Game and Fish Laboratory in Santa Fe, and by the Department of Biology at New Mexico Tech.
   Tambaqui is a fish that lives in freshwater. Juveniles can survive in brackish water when the salinity is gradually raised. Salinity levels above 20 g/L result in death. When juveniles are reared in salinities above 10 g/L, there is a significant detrimental effect on growth, haematological parameters and osmoregulatory.
  
  In an experiment, tambaqui had the pH of their water changed. No deaths occurred to tambaqui if the pH did not fall to 3.0. The only internal difference that was noted in tambaqui when the pH was being altered was a change in the acid-base of the plasma and red cells.
   A rise in air temperature results in a rise in water temperature, which is also very significant in water degradation as the water would become more susceptible to bacterial growth. An increase in water temperature can also affect ecosystems greatly because of a species' sensitivity to temperature, and also by inducing changes in a body of water's self-purification system from decreased amounts of dissolved oxygen in the water due to rises in temperature.

   Q10 (temperature coefficient), the factor by which a rate increases at a 10 °C increase in temperature, is used to measure how organisms' performance relies on temperature. Most have increased rates as water becomes warmer, but some have limits to this and others find ways to alter such effects, such as by endothermy or earlier recruitment of faster muscle.

   Given that species have limits to where they can exist, if conditions are unfavorable, mortality will be high and a species will be absent or rare in those areas. The corresponding graph representing this statement can be seen. The graph represents an experiment conducted using sand shrimp and their relative mortality rates based on salinity and temperature in a controlled environment. If climate change prompted the particular animal’s environment to become more or less salty, or too hot or too cold, and the organism was unable to move or to adapt, it would instead become extinct.

  The quality of drinking water is vital for human health. Peak water constraints result in people not having access to safe water for basic personal hygiene. "Infectious waterborne diseases such as diarrhea, typhoid, and cholera are responsible for 80 percent of illnesses and deaths in the developing world, many of them children. One child dies every eight seconds from a waterborne disease; 15 million children a year."
   The human body requires evaporative cooling to prevent overheating, even with a low activity level. With excessive ambient heat and humidity, adequate evaporative cooling does not take place. Human thermoregulatory capacity is exceeded. A sustained wet-bulb temperature or Wet-bulb globe temperature exceeding about can be fatal.
  
  Human response to heat stress can be hyperthermia, heat stroke and other harmful effects. Heat illness can relate to many of the organs and systems including: brain, heart, kidneys, liver, etc.

   Heat stress is a serious threat to crop production globally (Hall, 2001, 1992). Global warming is particularly consequence of increased level of green house gases such as CO, methane, chlorofluorocarbons and nitrous oxides. The Intergovernmental Panel on Climatic Change (IPCC) has predicted a rise of 0.3 °C per decade (Jones et al., 1999) reaching to approximately 1 and 3 °C above the present value by 2025 and 2100 AD, respectively.
  
  Section::::Physiological consequence of heat stress.
   When an energy transfer to or from a body is only as heat, the state of the body changes. Depending on the surroundings and the walls separating them from the body, various changes are possible in the body. They include chemical reactions, increase of pressure, increase of temperature, and phase change. For each kind of change under specified conditions, the heat capacity is the ratio of the quantity of heat transferred to the magnitude of the change. For example, if the change is an increase in temperature at constant volume, with no phase change and no chemical change, then the temperature of the body rises and its pressure increases. The quantity of heat transferred, , divided by the observed temperature change, , is the body's heat capacity at constant volume:
   "Odontaster validus" is much less sensitive to higher water temperatures than the other Antarctic marine species on which it feeds which mostly find temperatures above 3 °C lethal. Even when not killed at higher temperatures, many organisms cease to feed, may remain immobile or fail to reproduce and others started metabolising anaerobically. A study was undertaken to examine the implications of this for the Antarctic marine environment if water temperatures rise as a result of global warming.
   It has been theorised that low body temperature may increase lifespan. In 2006, it was reported that transgenic mice with a body temperature 0.3–0.5 C lower than normal mice lived longer than normal mice. This mechanism is due to overexpressing the uncoupling protein 2 in hypocretin neurons (Hcrt-UCP2), which elevated hypothalamic temperature, thus forcing the hypothalamus to lower body temperature. Lifespan was increased by 12% and 20% for males and females, respectively. The mice were fed "ad libitum". The effects of such a genetic change in body temperature on longevity is more difficult to study in humans; in 2011, the UCP2 genetic alleles in humans were associated with obesity.
   If present trends continue, 1.8 billion people will be living with absolute water scarcity by 2025, and two-thirds of the world could be subject to water stress. Ultimately, peak water is not about running out of freshwater, but about reaching physical, economic, and environmental limits on meeting human demands for water and the subsequent decline of water availability and use.

   Superheated water can be more corrosive than water at ordinary temperatures, and at temperatures above 300 °C special corrosion resistant alloys may be required, depending on other dissolved components. Continuous use of carbon steel pipes for 20 years at 282 °C has been reported without significant corrosion,
  
  and stainless steel cells showed only slight deterioration after 40–50 uses at temperatures up to 350 °C.
  
  The degree of corrosion that can be tolerated depends on the use, and even corrosion resistant alloys can fail eventually. Corrosion of an Inconel U-tube in a heat exchanger was blamed for an accident at a nuclear power station.
   The human body requires evaporative cooling to prevent overheating. Wet-bulb temperature, and Wet Bulb Globe Temperature are used to determine the ability of a body to eliminate excess heat. A sustained wet-bulb temperature of about can be fatal to healthy people; at this temperature our bodies switch from shedding heat to the environment, to gaining heat from it.
  
  Thus a wet bulb temperature of is the threshold beyond which the body is no longer able to adequately cool itself.

   Most organisms have a preferred temperature range, however some can be acclimated to temperatures colder or warmer than what they are typically used to. An organism's preferred temperature is typically the temperature at which the organism's physiological processes can act at optimal rates. When fish become acclimated to other temperatures, the efficiency of their physiological processes may decrease but will continue to function. This is called the thermal neutral zone at which an organism can survive indefinitely.
