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.
A different study was published in June 2019 that examined the association between hyperthermia in older adults and the temperatures in the United States. Hospitalization records of elderly patients in the US between 1991 and 2006 were analyzed and concluded that cases of hyperthermia were observed to be highest in regions with arid climates.
Central temperatures, such as rectal temperatures, are more accurate than peripheral temperatures. [30] Fever is generally agreed to be present if the elevated temperature [31] is caused by a raised set point and: Temperature in the anus (rectum/rectal) is at or over 37.5–38.3 °C (99.5–100.9 °F).
The temperature reading depends on which part of the body is being measured. The typical daytime temperatures among healthy adults are as follows: Temperature in the rectum (rectal), vagina, or in the ear (tympanic) is about 37.5 °C (99.5 °F) [20] [medical citation needed] Temperature in the mouth (oral) is about 36.8 °C (98.2 °F) [12]
The typical height of an adult human is between 1.4 and 1.9 m (4 ft 7 in and 6 ft 3 in), although this varies significantly depending on sex, ethnic origin, and family bloodlines. [ 239 ] [ 240 ] Body size is partly determined by genes and is also significantly influenced by environmental factors such as diet , exercise, and sleep patterns .
The mean body temperature of the orca is 36 to 38 °C (97 to 100 °F). [45] [46] Like most marine mammals, orcas have a layer of insulating blubber ranging from 7.6 to 10 cm (3.0 to 3.9 in) thick beneath the skin. [45] The pulse is about 60 heartbeats per minute when the orca is at the surface, dropping to 30 beats/min when submerged. [47]
In nearly all species of birds, an individual's sex is determined at fertilisation. However, one 2007 study claimed to demonstrate temperature-dependent sex determination among the Australian brushturkey, for which higher temperatures during incubation resulted in a higher female-to-male sex ratio.

The highest recorded temperature was 114 °F (45.6 °C) on June 27, 1994. [ 37 ] Winter afternoons in Lubbock are typically sunny and mild, but mornings are cold, with temperatures usually dipping below freezing, and as the city is in USDA Plant Hardiness Zone 7, lows reaching 10 °F or −12.2 °C occur on 1.5 mornings and 4.5 afternoons occur ...
