Heat acclimation alters the sleep behavior based thermoregulatory dynamics of rats in heat stress

Background: It is well understood that the high environmental heat significantly affects the brain physiology of mammals, particularly the sleep and behavior of the subjects. The objective of the present work is to quantify the effects of acclimatization to the high environmental heat on sleep and behavioral activities in heat stress conditions. Methods: The polygraphic data involved simultaneous recor (EOG), and electromyogram (EMG) were recorded both on chart as well as in digital format to study the sleep three different age groups of freely moving rats following exposur into four groups: the acute heat stress group, subjected to a single exposure of 4h at 38°C in the biological oxygen demand ( incubator; the chronic heat stress group, exposed for 21 days, for 21 days of chronic heat acclimatization and the handling control group. Open field and elevated plus analyzed following different exposure setup of high environmental h Results: The analyses of results suggest that acclimatization to the high environmental heat significantly alters the effects of acute exposure of high environmental heat on different sleep Conclusion: Acclimatization to environmental heat shifts the thermoregulatory set and behavior have been observed.
