1. In urethane or ketamine‐anaesthetized rats, salivary secretion was observed when local brain sites trunk skin were stimulated thermally electrically. 2. Salivary facilitated by bilateral warming. Sensitive restricted to the preoptic area and anterior hypothalamus, but in a region distinct from previously reported sensitive site for producing saliva‐spreading behaviour. 3. Unilateral warming of produced greater ipsilateral submandibular/sublingual glands than contralateral glands....

We examined the relationship between body temperature, tail vasomotor response, and work intensity at different ambient temperatures in rats, using a treadmill continuously measuring oxygen uptake during exercise. At an temperature (Ta) of 24°C, rectal (Tre) beginning vasodilation exercise increased proportion to intensity. After Tre remained steady, end 30min level was proportional Ta 14°C, slightly higher than intensities. 4°C, rose slower Tas even dropped relatively low Tail did not occur...

1. At neutral (24 degrees C) and at hot (40 ambient temperatures (Ta) salivary secretion from the submandibular gland of freely moving rats was recorded, together with simultaneous observation saliva‐spreading behaviour (grooming). 2. a Ta 24 C, basal flow less than 2 microliters/min. When were first placed in experimental chamber, brief grooming bouts often occurred. Transient more 10 microliters/min associated this grooming, rate positively correlated duration activity. 3. 40 appeared...

The present study explored the laterality of central nervous thermoregulatory control in anesthetized rats by measuring paw skin vasomotor activity and cold-induced shivering hind leg muscles during unilateral preoptic area anterior hypothalamus (POAH) warming electrical stimulation or thermal abdominal skin. Unilateral POAH produced vasodilation on both sides body, but ipsilateral side always either occurred at a lower threshold hypothalamic temperature was stronger than contralateral side....

Rats exercised on a treadmill at daytime lows and nighttime highs of circadian change in body temperature two different work intensities [40 60% maximal oxygen uptake (VO2max)] with the ambient (Ta) 24 degrees C. Immediately before exercise VO2max, rectal (Tre) was 0.7 C higher night than during day. During exercise, Tre rose more day night, end same as night. Threshold for tail vasodilation did not differ between Similar tendencies vasomotor response were observed intensity 40% except that...

The mechanism for reduced voluntary water intake during immersion was studied in eight men (19–25 yr of age) immersed to the neck while sitting 3 h at 34.5 degrees C or air 28 when euhydrated (Eu-H2O and Eu-air, respectively) hypohydrated (Hypo-H2O Hypo-air) by 3.6% body weight loss. Thirst sensations (degree thirst, mouth dryness taste, drinking desirability, stomach fullness) were similar beginning Hypo-air Hypo-H2O test periods. Initial tap (15 C) 216 +/- 30 ml/7 min (P less than 0.05)...

Electrolytic lesions aimed at the suprachiasmatic nuclei (SCN) were made in male Long-Evans rats. Body temperature (Tb), activity, and drinking monitored continuously a 12-h light:12-h dark (12:12 LD) cycle an ambient of 23°C. Large SCN eliminated activity drink ing rhythms abolished or reduced circadian rhythm Tb. The Tb responses rats measured L after exposure to cold injection lipopolysaccharide (LPS), fever-producing drug, both D during 30-min novel cage. Rats with (SCNX) maintained...

With increasing heat-wave frequency, the prevention and public awareness of heat-related illnesses has become an essential topic. In standard for heat strain stress, empirical guidelines to prevent excess core temperature rise above 1 °C have been prescribed workers. However, measuring change in our daily life or working place is not straightforward. The estimation from measured vital signals a non-invasive manner thus management stress strain. Here, we propose method by simplified...

Understanding factors associated with physical activity (PA) is important to promote PA. The purpose of the present study was investigate achieving PA guideline in 293 Japanese adolescents (140 boys and 153 girls). Time spent moderate vigorous (MVPA) accessed by using accelerometers. Based on MVPA, participants were classified as "Active" (≥60 min/day MVPA) or "Inactive" (<60 MVPA). Anthropometry, age, screen time, mental health, participation after-school sport activities, sleep status,...

To study the mechanism of rise in body temperature during exercise, endogenous pyrogen was administered to exercising rats. At rest and at a neutral ambient (Ta) 24 degrees C, intravenous injection recombinant human interleukin 1 (IL-1, 40 micrograms/kg) produced 0.5 degree C rectal (Tre) from 37.4 C. Ta 34 which Tre 38.6 response IL-1 only 0.2 greater than when saline used. In first series exercise experiments, rats ran on treadmill after or two different work intensities (estimated 60%...

Physical-condition management is becoming more important to improve the safety of work sites, such as preventing heat stroke caused by intense heat.We at NTT Device Innovation Center have developed a physical-condition technology for creating comfortable sites using wearable-device sensors and data-analysis we thus far, knowledge thermal exercise physiology in collaboration with specialists.This article introduces problems management, how our can solve these problems, results from verifying...

The purpose of the present study was to examine associations between physical fitness and body fatness with blood lipid profile in 231 Japanese children adolescents (12.1 ± 1.5 years). primary outcomes were a risk score which calculated by summing up z scores three items (triglycerides, low density lipoprotein-cholesterol, high lipoprotein-cholesterol). Physical assessed using standardised test. For fatness, percentage overweight age-, sex-, height-specific mass. combined analysis (fitness ×...

In the field of Crime Prevention Through Environmental Design (CPTED), it is said that natural surveillance, which means building occupants or passersby keep a lookout for potential crime offenders in ways, important prevention urban areas. Recently, methods modeling surveillance have been developed. However, by existing methods, difficult to measure with both high resolution and efficiency. Therefore, this research aims develop mapping areas higher more efficiency than methods. We propose...

The number of patients experiencing heat-related illnesses has gradually increased due to global warming. Owing an aging society, 50% with in Japan are elderly. Core temperature is one key parameter for health care; however, its monitoring virtually impossible. Internet Things (IoT) devices healthcare have been proposed; the vital parameters be monitored remain controversial. Here, we assessed core elderly who were transported hospitals by ambulance from their homes. patients' temperatures...

To clarify the independent changes of insulations body tissues (Itissue) and wet suit (Isuit) in wet-suited subject during underwater exercise, overall heat flow from skin (Htissue) (Hsuit) esophageal (Tes), (Tsk), temperatures were measured at 1, 2, 2.5 atmospheres absolute (ATA) critical water temperature (Tcw). The average Tcw nine men (23-38 yr) was 22.3 +/- 0.2, 26.3 28.0 0.4 degrees C (SE) ATA, respectively. At each pressure male volunteers wearing 5-mm neoprene suits completed three...
