Article Synopsis
- Light is a key factor that influences body rhythms through the suprachiasmatic nucleus (SCN) in the hypothalamus, but social interactions also play a significant role in modulating these processes.
- A study with male mice showed that social isolation affected the dorsal part of the SCN, resulting in fewer active neurons when housed alone compared to those in groups, especially during light phases.
- The findings suggest that social interaction can mask the effects of light on SCN activity and help maintain consistency between body temperature and activity rhythms, highlighting the importance of both light and social factors in regulating circadian rhythms.

We investigated whether the magnitude of exercise-induced hyperthermia influences intestinal permeability and tight junction gene expression. Twenty-nine male Wistar rats were divided into four groups: rest at 24 °C and exercise at 13 °C, 24 °C or 31 °C. The exercise consisted of a 90-min treadmill run at 15 m/min, and different ambient temperatures were used to produce distinct levels of exercise-induced hyperthermia.
