“…Thus, in the current experiment, the decrease of sympathetic nervous tone to the skin of the extremities during the night-time might have not been greater with Type H clothing. Fruhstorfer et al (1988) have demonstrated that daytime stress induced a greater decrease of adrenaline during the sleep period. This might account for the lack of significant difference in the range of circadian oscillation of rectal temperature between the two clothing types (Table I), and accords with our previous finding (Park & Tokura 1998) that the evening fall of rectal temperature was significantly and positively correlated with the decrease of adrenaline at this time.…”

The purpose of this study was to determine whether the different thermal conditions of the arm and leg due to wearing different types of clothing during the afternoon could modulate the circadian rhythm of body temperature and subjective sleep quality. Six healthy female volunteers were studied twice with two types of clothing, leaving the arm and leg covered or uncovered. The environmental chamber was controlled at 24 + 0.58C and 50 + 5% RH during wakefulness and 28 + 0.58C and 50 + 5% RH during night sleep. One type of clothing consisted of long-sleeved shirts and full-length trousers (Type L, 989 g, 0.991 clo); the other type was of half-sleeved shirts and knee-length trousers (Type H, 750 g, 0.747 clo). When wearing Type H rather than Type L clothing, skin temperatures of the arm and leg were significantly lower during the time of exposure, and increased more after the evening. (2) Rectal temperature was not significantly different between the two types of clothing except during the early part of the exposure period, but it decreased during the evening by a significantly greater amount when wearing Type H clothing. (3) Subjective sleep quality was not significantly different between the two clothing types. These results suggest that afternoon exposure of the arm and leg to a slightly cool environment does not have a strong after-effect on the body temperature and subjective sleep quality.

“…1996; Park & Tokura 1998). These reports suggest that the stress of some factors (noise, light, and temperature stimulus) during daytime affected the night‐time epinephrine dynamics, which are related to core body temperature (Åkerstedt & Fröberg 1979; Fruhstorfer et al . 1988).…”

The timing of parturition was recorded for a total of 56 beef cattle (Japanese Black × Holstein Friesian) on different dietary treatments. The rate of calving during daylight hours in cows night-fed (18.00 hours) with a roughage diet was significantly higher than that in cows night-fed with a high concentrate diet (79.2% vs 38.5%, P < 0.05). Subsequently, the vaginal temperature (VT) of these cows was analyzed using a cosinor method. When the feeding schedule was changed from twice daily (08.30 and 15.30 hours) to night feeding, the periodicity, the acrophase and the bathyphase, which were the parameters of the cosine curve, were unstable from the first day of night feeding until after day 6 (P < 0.05). Prior to parturition, the midline-estimating statistic of rhythm (MESOR) and the amplitude for the cows that were fed a high-roughage diet at night and that calved at night-time were lower and larger, respectively, than that for the other treatments (P < 0.01). Based on these results, the time of parturition in most of the beef cows was influenced by feeding time and diet composition. Those cows that calved at night-time in spite of night feeding had lower vaginal temperatures.
