Miliary tuberculosis, bacterial endocarditis, biliary tract disease including liver abscess and viral hepatitis, pyelonephritis, abdominal abscess, osteomyelitis, and brucellosis are the major infections encountered. Second, 3M Spoton applying on temporal artery. On average, the skin temperature is estimated to be systematically cooler by 0.15 0.1 K compared to the temperature at 5m depth. Skin temperature depends on air temperature and time spent in that environment. The precision (average of the absolute value of the difference between estimated and measured mean body temperatures) is 0.28 0.23C (95% confidence interval, 0.26 to 0.30C). Is it OK to ask the professor I am applying to for a recommendation letter? The three hypothetical schematics show how body temperature may be regulated within an individual thermoeffector loop. How To Distinguish Between Philosophy And Non-Philosophy? You could be sitting in a chilly room or too close to an air conditioner. Atkins E, Bodel P. Clinical fever: its history, manifestations and pathogenesis. Temperature Tolerance In Relationship To Body Temperature. Over the entire data set, 91% of the mean body temperature estimates were within 0.5C of the measured values. To learn more, see our tips on writing great answers. Careers. Once again, most heat balance models make this assumption and still produce experimentally verifiable results.18Finally, hand and foot temperature was estimated from deep temperatures. Deep temperatures are at best an approximation of average tissue temperature in these inhomogeneous structures; fortunately, both the hands and feet are small and thus contribute relatively little to MBT. The nadir in body temperature usually occurs at about 4 a.m. and the peak at about 6 p.m. Please remove one or more studies before adding more. Does the LM317 voltage regulator have a minimum current output of 1.5 A? (topper, ~5-cm thickness) were placed on top of the . Temperature. The skin is the largest organ in the human body. Temperatures above 40 C are often favourable conditions for receptiveness to chemotherapy and radiotherapy. Thermoregulation -Temperature Regulation In Skin - Hypothermia And Hyperthermia. At a third stage, when all attempts at compensation by the temperature regulatory center fail, the body loses heat like an inanimate object. We conclude that Burtons 1935 formula is remarkably accurate and precise. Normal skin temperature for healthy adults ranges between 92.3 and 98.4 Fahrenheit or 33-37 Celsius, far lower than the 98.6 F average core temp. 6 C. A wearable device for non-invasively measuring a user's body temperature includes a housing, a first substrate coupled to the housing and having an opening, a second substrate coupled to the first substrate and configured to be fixed to the user's skin, a housing, and the like. Mean (SD) mean body temperature was 36.8 (0.5)C at epidural top-up and 36.9 (0.6)C at delivery. Mapping the skin temperature and pressure in specific areas of the body can facilitate the determination of human health status and provide predictive information to prevent disease. Three infectious diseases in which a relative bradycardia occurs are mycoplasma pneumonia, psittacosis, and typhoid fever. The temperature of two systems is the same when the systems are in thermal equilibrium. [10] Meanwhile, skin surface temperature has been observed to be higher over active organs rather than those at rest, as well as over muscles rather than tendons or bones. [10], Other notable influences on skin surface temperature include instances of heat stress (in which significant portions of cardiac output are directed to the skin), lowered skinfold thickness (contributes to significantly greater surface temperature variation during exercise)[13] and local thermal control of cutaneous blood vessels (local heating may prompt vasodilation whilst local cooling decreases blood flow to the skin). accuracy is dependent, to a large degree, on sensor placement. Normal body temperature varies by person, age, activity, and time of day. The oral temperature is measured with the probe placed under the tongue and the lips closed around the instrument. Patients might not pay close enough attention to early signs of hyperthermia, such as headache, piloerection, and chills; and, at times, the first manifestations recognized (by others) are changes in gait, speech, or mental status. Anesthesiology 2000; 93:62937, Xiong J, Kurz A, Sessler DI, Plattner O, Christensen R, Dechert M, Ikeda T: Isoflurane produces marked and non-linear decreases in the vasoconstriction and shivering thresholds. Are there any benefits/disadvantages/traits from having a permanent lower core temperature? When attached to human skin, 7 W/cm2 of electricity was generated from the body temperature only.) As might be expected, the formula was somewhat less accurate at the coldest temperatures and especially poor during the rapid cooling phase. However, one could point to remarkable recovery of patients with temperature documented below 18C (65F) or above 44.5C (112F). When you are too hot, the blood vessels in your skin widen to carry the excess heat to your skin's surface. Skin temperature is the temperature of the outermost surface of the body. Gender Role: The main measurement indicators are (1) skin temperature, body temperature, and heart rate. Heat flows from higher to lower temperature, so the human skin will not drop below that of surrounding air, regardless of wind. Please refer to this study by its ClinicalTrials.gov identifier (NCT number): NCT03745079. Hence, Burtons formula should be used cautiously in applications where accurate detection of small changes in body heat content is required. Examples of relapsing fever can be seen in Hodgkin's disease (Pel-Epstein fever), P. vivax malaria, Borrelia infection, and rat-bite fever due to Spirillum minus. New York: Marcel Dekker, 1979. rev2023.1.18.43176. Infections account for about one-third of FUOs. In some patients with these diseases, the febrile state might not be recognized because they will raise their temperature to less than 37.2C (99F). The surface volume of skin means there are regional variations in temperature. A number of medical conditions affect skin temperature in humans and may prove harmful or fatal to individuals suffering from such conditions when the function of skin is impaired. Young EJ, Fainstein V, Musher DM. For example Thermofocus. [14][38] This is because sites of tumour growth are often associated with increased immune response causing inflammation, which effectively increases skin temperature, departing from the spatial homogeneity of skin temperature in the breasts. Dissipation of heat depends on vasomotor changes that regulate blood flow to the skin and mucous membranes and sweating. Normal rectal temperature is typically 0.27 to 0.38C (0.5 to 0.7F) greater than oral temperature. Changes in core body temperature are usually detected sooner in the tympanic membrane than in other sites, such as the rectum, mouth or under the arm. Drug fever: a critical appraisal of conventional concepts. Recently developed 3M Spoton skin temeprature which is applied on temporal artery is correlated with core temperature measured by esophageal prove in several studies. It is used to diagnose different types of diseases. -, Almeida, M.C., HewButler, T., Soriano, R.N., Rao, S., Wang, W., Wang, J., Tamayo, N., Oliveira, D.L., Nucci, T.B., Aryal, P., Garami, A., Bautista, D., Gavva, N.R. Conventional core temperature is monitored at esophagus, rectum, nasopharynx. Hypothermia can be due to infection and bacteremia, ethanol or drug ingestion, exposure, a central nervous system event, cachexia from malignancy or malnutrition, gastrointestinal bleeding, or endocrine deficiencies such as panhypopituitarism, myxedema, Addison's disease, uremia, and hypoglycemia. The Health Monitor lets you view all of your personal metrics in a single location, including skin temperature, live heart rate, HRV, resting heart rate, pulse oximetry and respiratory rate. (b) Deep body temperature is controlled by the same negative feedback loop (from deep body temperature) supplemented by a feedforward signal (ambient temperature). Molecular basis of fever in humans. Exercise and heavy work may be responsible for production of heat that raises core temperature 1 to 1.5C (2 to 3F), but the temperature usually returns to normal within 30 minutes of cessation of exertion. It is inferred from satellites in the 8-12 um window region. The normal axillary temperature is usually a degree lower than the oral (by mouth) temperature. Our calculations make the further assumption that each leg segment is cylindrical. Patients who scheduled surgery more than 2 hours under general anesthesia. Skin temperature may also be an indicator of the presence of cancer. what's the difference between "the killing machine" and "the machine that's killing". MacKowiak PA, LeMaistre CF. Endogenous pyrogen is a protein of 15,000 daltons produced by neutrophils, eosinophils, monocytes, Kupffer cells, and alveolar macrophages, when they are exposed to exogenous pyrogens. Closely regulated temperature is imperative for normal and efficient functioning of organ systems. Excessive exposure to high ambient temperatures, an increase in heat production (either by increased metabolism or, more often, by increased muscular work) or loss of the ability to dissipate sufficient body heat may result in hyperthermia. The surface volume of skin means there are regional variations in temperature. [4], The skin is composed of three main layers, the epidermis, dermis and hypodermis, and contains a variety of cells, receptors and junctions which enable performance of a multitude of functions. The closer the target is to the sensor the smaller the area and the further the sensor from the target the larger the area. To learn more about this study, you or your doctor may contact the study research staff using the contacts provided below. This leads to the production of sweat and this helps to cool the body. Tiny muscles arrector pili , control the position of the hairs on your skin. The area of the eye closest to the nose is the measurably hottest spot on the face. Interdependency of Core Temperature and Glabrous Skin Blood Flow in Human Thermoregulation Function: A Pilot Study. The https:// ensures that you are connecting to the First: 98.6 32 = 66.6 Then: 66.6 5 = 333 Then: 333 / 9 = 37 C. I read in many sources that these IR thermometers only measure the temperature of the object's surface. [16][17] Evaporation and convection of sweat cause a loss of body heat from the skin surface to the environment, providing an effective means for lowering body temperature. Vacationers unaccustomed to saunas and hot tubs are another high-risk group for hyperthermia. Participants' temperature measured at 3 places at the same time. In page 24 there is a table for measurements for T_c. Such weather factors as wind chill and humidity cause changes in skin temperature. Another important factor that is not common knowledge is the way that ambient temperature can affect body . Feedback and feedforward in thermoregulation. Electric digital thermometers are more convenient than glass instruments because the probe cover is disposable, response time is quicker (allowing accurate measurements within 10 to 20 seconds), and there is a signal when the rate of change in temperature becomes insignificant. The formula used to convert temperature from Kelvin to Celcius is C = K 273.15. Talk with your doctor and family members or friends about deciding to join a study. [14], Skin temperature is a crucial aspect of human physiology and often plays a significant role in affecting thermoregulatory processes. A decrease in metabolism, an abnormality in mechanical muscular function, or exposure to ambient temperatures below the normal body temperature may result in hypothermia. Most infectious causes of fever are naturally self-limited (such as viral diseases) or easily diagnosed and treatable bacterial diseases of the pharynx, ears, sinuses, upper respiratory airways, skin, and urinary tract. Heat loss from the skin to the external environment is a significant factor contributing to acute hypothermia. Sustained or continued fever, characterized by temperature elevation with little (less than 1C) diurnal fluctuation, is seen in patients with pneumococcal pneumonia and typhoid fever. The early stage of hypothermia (35 to 32.8C; 95 to 91F) is marked by an attempt to react against chilling including shivering, increased blood pressure and pulse, vasoconstriction, and diuresis. Why humans have the temperature they have? Patients with fever usually exhibit warm, flushed skin, tachycardia, involuntary muscular contractions or rigors, and sweating or night sweats. Solution: Fahrenheit to Kelvin conversion formula is given by: K = (F 32) 59 + 273.15 = (113 - 32) (5/9) + 273.15 = 81 (5/9) + 273.15 = 45 + 273.15 = 318.15 2010 May;109(1):13-25. doi: 10.1007/s00421-009-1216-1. [14][12] In certain cases of hyperthermia, skin vasodilation has permitted blood flow rates of skin to reach volumes of six to eight litres per minute.[14]. Stimulation of muscle protein degradation and prostaglandin E. Dinarello CA, Wolff SM. Body temperature is maintained at 37C as a result of balance between heat generation and heat loss processes. This discovery was supported by comparison of changes in deep skin temperature to changes in surface skin temperature. These usually are circumscribed illnesses of less than 7 to 10 days that do not require hospitalization and result in no long-term sequelae. Dissipation by convection is more efficient when ambient wind current is increased; evaporation is the primary mechanism in high ambient temperatures, unless the atmosphere is saturated with water vapor. The multisensory, multieffector thermoregulation system can be described, Two types of skin in a rat. [1] Recording skin temperature presents extensive difficulties. [18], The preoptic nucleus of the anterior hypothalamus acts as the regulatory centre for the body's heat loss. The performances of these instruments are both highly valid and reliable, and in essence, are equal for purposes of clinical electrodiagnostic readings. For example, distal esophageal temperature is usually the best minimally invasive core temperature measurement site but is subject to artifact during cardiopulmonary bypass and is accordingly less reliable than the nasopharynx in these patients. Front Psychiatry. In addition, uremics and quadraplegics may have blunted febrile responses, whereas patients with extensive surface burns or dermatologic conditions may have exaggerated and sustained fevers. I also found more work based on the conversion of surface temperature to core temperature. you have the DOI and can look it up). In climate models, it is the temperature used to determine upward thermal emission. 2. Skin acts as both a medium and means for delivering mechanisms of thermoregulation, including insulation, sweating and control of blood flow. Clinical Methods: The History, Physical, and Laboratory Examinations. The consequences of these attacks can be severe, potentially causing Gangrene, a destructive implication of abnormal skin temperature. Baracos V, Rodemann HP, Dinarello CA. You have reached the maximum number of saved studies (100). Intermittent fevers are seen in patients with malaria, abscesses, and cholangitis. View this study on Beta.ClinicalTrials.gov, U.S. Department of Health and Human Services. [29] It is important to note that induced mild hypothermia, between temperatures of 33C and 36C is effective whilst safer than moderate hypothermia, reducing body temperature to the range between 28C and 32C. concluded in "Relationship between core temperature, skin temperature, and heat flux during exercise in heat" that: Algorithms for T_c measurement are location-specific and their The skin of your fingers and toes may be drastically lower from the temperature taken on your forehead. These changes might suggest that men retain more metabolic heat in various locations on the back when exercising in a hot, humid environment compared to women. Nature 448, 204208 The site is secure. Your skin protects your body from germs and regulates body temperature. HHS Vulnerability Disclosure, Help Changes over time were analysed with repeated measures ANOVA. Over-insulation or exposure to ambient temperatures greater than 37.8C (100F), especially in conditions of 100% water vapor pressure and dehydration, interfere with the normal mechanisms for heat dissipation. [23][24][25], Hypothermia is defined as having a core body temperature below 35C (or 95F). MathJax reference. Individual Participant Data (IPD) Sharing Statement: Studies a U.S. FDA-regulated Drug Product: Studies a U.S. FDA-regulated Device Product: Esophageal core temperature measured by stethoscope [TimeFrame:3 hours (during general anesthesia)], Carotid skin temperature by SpotOn, [TimeFrame:3 hours (during general anesthesia)], Temporal skin temperature by SpotOn, [TimeFrame:3 hours (during general anesthesia)], Room temperature, [TimeFrame:3 hours (during general anesthesia)], Who need surgery more than 2 hours under general anesthesia, American Society of Anesthesiologists physical status 1 or 2. Cold- and warm-sensitive nerve endings located in the skin send signals, The menthol receptor TRPM8 is the principal detector of environmental cold. [1] Consequently, a uniform temperature is not typically maintained by skin as a whole, as demonstrated by inconsistencies between different regions of the body even in spite of measurements taken under various external conditions. Yes. Endogenous pyrogen causes increased firing of hypothalamic, thermosensitive neurons, resulting in the augmentation of heat conservation and production mechanisms, with resultant fever. Casey Meserve is a writer at WHOOP. To our surprise, Burtons formula worked remarkably well over the entire tested range of MBTs from 31 to 36.5C. Rarely is marked fever present for more than 3 to 4 days in these patients. In particular, during sports the skin temperature and core body temperature may show very little correlation. Augmented heat loss at the palm-water surface might enable cooler blood to . A temperature over 100.4F (38C) most often . Pharmacological blockade of the cold receptor TRPM8 attenuates autonomic and behavioral cold defenses and decreases deep body temperature. . Effects of thermal stress during rest and exercise in the paediatric population. The active elements of each loop (in principal, thermoreceptors and the thermoeffector) are marked as the active system; the passive system (processes of heat transfer) is marked as heat transfer. To convert a temperature in Fahrenheit to Celsius, subtract 32 from the Fahrenheit temperature and multiply that number by 0.555. This balance involves autonomic nervous system, metabolism, and behavioral responses. The purpose of this study is comparing 3 methods of temperature monitoring. The feedforward control signal is shown in red. Thanks for contributing an answer to Biology Stack Exchange! Pflugers Arch. & Romanovsky, A.A.2006. Occasionally these signs are absent or minimal, and dry, cold skin or extremities are detected in spite of a significant rise in core temperature. J Biomech Eng. which is included in the paper (regarding copyright laws, I'm not allowed to put it here. A core temperature over 100.4F (38C) is defined by medical experts as a fever caused by an infection or illness. [39] In thermography, the skin temperature of each breast is monitored utilising techniques such as infrared imaging and liquid crystal contact thermography (LCCT). Measurements made by electric devices are less easily influenced by manipulation of the instrument. Therefore, we measured core body temperature at the tympanic membrane,11nasopharynx,9,10or distal esophagus12in our studies. Defined: The degree or intensity of heat or cold, with reference to some standard value. Its mechanism is making zero heat flux on skin applied. Would Marx consider salary workers to be members of the proleteriat? Handb Clin Neurol. These patients usually have sustained (sometimes intermittent) fever, appear entirely well, have an excellent appetite, and are inquiring about discharge from the hospital. The best morning routine will promote both productivity and reduce anxiety about the day ahead. Your skin is your largest organ, making up approximately 15% of your total weight. This is called thermoregulation and allows your body to preserve or discharge heat based on its needs. One main role of the skin is in thermoregulation, where cutaneous blood flow, and hence skin temperature, vary widely in order to help preserve core body temperature. Relapsing indicates that bouts of fever are interspersed with afebrile periods of days to weeks. The body is very good at keeping its temperature within a safe range, even when temperatures outside the body change a lot. We thus compared the two methods and found, perhaps surprisingly, that Burtons formula worked welleven during severe thermal perturbationsover the range of core temperatures from 18.5 to 37.1C. [19] Internal body heat is released to the environment at a greater rate with low skin temperature, as heat follows temperature gradients from regions of high temperature (the body's internals) to another location of lower temperature, as described by the second law of thermodynamics. We measured body temperature and metabolic rate in animals exposed for short periods (1 h)to air temperatures ranging from 10 to 45 C and for long periods (8 h) to air temperatures ranging from 10 to 30 C. Most of us are aware that our body's core temperature range is typically between 36.5-37.5 C, but did you know that skin temperature (what thermal and infrared sensors detect) is significantly lower than core body temperature? For cooperative patients, the oral glass thermometer is recommended because of its convenience and patient acceptance. When hypothermia is suspected, a rectal probe and thermocouple capable of measuring as low as 25C is essential. [21] Beyond injury management, cryotherapy has notable surgical applications (referred to as cryosurgery), in which extremely cool temperatures produced by liquid nitrogen and argon gas are targeted towards malignant tumours in efforts to damage and destroy such tissue. My question is how to convert someone's skin temperature to their core temperature (Thermofocus does it so I understand that it's possible). Get tips on creating a routine that wakes you up and gets you going. Irreversible long term brain injury occurs in around one in five people affected by the condition. 1 Reaumur [r] = 274.4 kelvin [K] Clues for a "factitious" fever due to thermometer manipulation include a temperature of more than 41.1C (106F) in a patient who looks well, has no chills or rigors, shows no diurnal variations of temperature, has no tachycardia or tachypnea, and has no increase in the temperature of a freshly voided urine specimen. Temperatures of these parts typically are consistent with internal body temperature. Other factors to take into account are: In general, rectal temperatures are considered to be more accurate when checking for fever in a young child. In adults, neoplasms are the cause of FUO in about 20% of cases. [16] These bumps serve to facilitate the pilo-erection of hairs or "standing on end", essentially perpendicular to the skin surface. The sea surface skin temperature is the temperature measured by an infrared radiometer typically operating at wavelengths in the range 3.7 - 12 micrometers. Joggers and road runners are particularly prone to hyperthermia, especially during the summer months in areas where temperature is above 32.2C (90F) and humidity above 90%. Three minutes dwell time is required. Medical research hasn't determined an exact correlation between. Federal government websites often end in .gov or .mil. A rectal temperature is 0.5F (0.3C) to 1F (0.6C) higher than an oral temperature. From chills to chilis: mechanisms for thermosensation and chemesthesis via thermoTRPs. Bland-Altman plot of 535 data pairs 10,12,when the studies of deep hypothermia for circulatory arrest 9,and fever 11were excluded. The authors thank Gilbert Haugh, M.S., for the statistical analysis and Nancy Alsip, Ph.D., for editorial assistance (both from the Outcomes Research Institute at the University of Louisville, Louisville, Kentucky). Factitious, or feigned, fever is produced by the patient who, for reasons of secondary gain, is trying to simulate an organic illness. Lymphomas (Hodgkin's and non-Hodgkin's) and neoplasms (hepatoma, atrial myxoma, and hypernephroma) are frequent causes. Why did OpenSSH create its own key format, and not use PKCS#8? Lancet 1986; 1:30710, Wissler EH: Comparison of computed results obtained from two mathematical models: A simple 14-node model and a complex 250-node model. This reduces blood flow to your skin to save body heat. Casey lives in the woods of Rhode Island and enjoys growing vegetables and flowers for the deer to eat, running (slowly) and watching the Boston Bruins. Intermittent fevers are often accompanied by rigors and profuse night sweats. Why Should I Register and Submit Results? The normal temperature of skin is about 33 C or 91 F. However, body size has a major effect on how this is achieved. At a given core temperature, higher skin temperature improves the sweat rate, whilst cooler skin temperature inhibits sweat rate. The algorithm for an inverse conversion of the blood flow signal into the skin temperature signal is addressed. When endogenous pyrogen is liberated into the bloodstream, it interacts with the preoptic regions of the anterior hypothalamus and raises the thermoregulatory set point to a variable degree, but usually not greater than 41.1C (106F). Lomax P, Schonbaum E, eds. Sweat begins to evaporate off your skin in a process that consumes heat, lowering the body's temperature. Pathogenesis of fever in man. In summary, direct measurement of peripheral tissue temperature can be accomplished by insertion of sufficient needle thermocouples, combined with relatively complex calculations; the procedure is complex, painful, and risky. Classically described fever patterns can be helpful in indicating the possible causes of infections. They also proposed two relationships for calculation of T_c based on T_s (Core temp. the hand), which are also used to explore the environment. Additionally, skin temperature has important clinical implications and may also appear as a symptom for a given condition. 2022 Aug 17;29:871-899. doi: 10.1016/j.omtn.2022.08.020. Updates include citations for those works. Disclaimer, National Library of Medicine Celsius to Fahrenheit conversion formula is given by: F = C (95) + 32 = 50 (9/5) + 32 = 90 + 32 = 122 Therefore, 50C = 122F Question 3: Convert 113F to Kelvin. System properties, feedback control and effector coordination of human temperature regulation. The international standard for assessing the most accurate skin measurement is in the inner canthus or the warmest area on the face. Water boils at 100C or 212F. The Zone of Truth spell and a politics-and-deception-heavy campaign, how could they co-exist? An intermediate stage (32.2 to 24C; 90 to 75F) is characterized by decrease in metabolism; drop in pulse, blood pressure, and respiration; muscular rigidity; a fine tremor; and respiratory and metabolic acidosis. Am J Emerg Med 1997; 15:3835, Hayes JK, Collette DJ, Peters JL, Smith KW: Monitoring body-core temperature from the trachea: Comparison between pulmonary artery, tympanic, esophageal, and rectal temperatures. Recent studies have shown that the normal body temperature can have a wide range, from 97F (36.1C) to 99F (37.2C). The multisensory, multieffector thermoregulation system can be described as a federation of relatively independent thermoeffector loops (Romanovsky 2007b). Because patients are prone to hypothermia during surgery. Those at most risk fail to wear proper clothing, wear impermeable sweatsuits, or exercise after taking phenothiazines, anticholinergic drugs, or alcohol. An immoderate decrease and increase in CBT can cause hypothermia and heat stroke, respectively ( Yousef et al., 2021 ). government site. [2] Lower temperatures are characteristically observed in proximity to superficial veins, relative to superficial arteries, and over protruding body parts including the toes, fingers, ears and nose. The precision (average of the absolute value of the difference between estimated and measured MBTs) was 0.28 0.23C (95% confidence interval, 0.26 to 0.30C). Skin temperature was found to provide relevant information for estimating core body temperature, although the use of single skin temperatures underestimated rectal temperature ( Mendt et al., 2017 ). It also keeps body temperature normal (37 C). Also This Work shows that, although the temperature distribution pattern among genders are similar, women have lower skin temperature. Two types of skin in a rat. The skin temperature also plays a secondary role in controlling cooling in the heat: at the same core temperature, a warmer skin temperature enhances the sweat rate, and a colder skin inhibits it (Stolwijk et al., 1971; Nadel et al., 1971). An indication is also an elevated body temperature. Accordingly, fluctuations in skin temperature over large portions of the breasts are often investigated in hopes of revealing sites of tumour growth. Fortunately, previous work4,8indicates that the formula is highly accurate in nearsteady state neutral conditions. The presence of fever is underestimated by palpation in 40% of individuals, even when the measured temperature is as high as 39C (102.2F).
