PSYCHOLOGY OF EMOTIONS

Detailed explanation-1: -The circadian system modulates metabolic heat production to generate the body temperature rhythm, which challenges homeothermy but does not abolish it. Individual cells do not regulate their own temperature, but the relationship between circadian rhythms and metabolism at the cellular level is also discussed.

Detailed explanation-2: -Human body temperature has a circadian rhythm with a 0.8-1°C oscillation between a diurnal maximum and a nocturnal minimum (Moore-Ede et al. 1982; Cagnacci et al. 1996).

Detailed explanation-3: -Body Temperature and Circadian Rhythm Sleeping and waking are directly tied into our temperature, which has a daily high (about 8-12 hours after waking), and a temperature minimum (about 1.5-2 hours before your average wake-up time).

Detailed explanation-4: -Changes in our body and environmental factors can cause our circadian rhythms and the natural light-dark cycle to be out of sync. For example: Mutations or changes in certain genes can affect our biological clocks. Jet lag or shift work causes changes in the light-dark cycle.

Detailed explanation-5: -Physiological body temperature is approximately 37.0 °C in healthy subjects, with a nearly 1 °C sinusoidal circadian fluctuation [1, 2].
