The aim of our present study was to establish if there are any changes in core temperature and plasma glucose concentration during exposure to bright (5000 lx) and dim (100 lx) light. Ten healthy women (age: 19.6 ± 1.66 years) were studied in climatic chamber in which ambient temperature and relative humidity were maintained at 26°C and 60% RH, respectively. Rectal temperature was measured every 5 min and blood samples for determination of glucose were collected every 2 h. Each participant took part in both sessions in bright light and dim light conditions on different days with an interval of at least 1 day. Our results have shown that glucose concentration increases in bright light conditions as compared to dim light conditions but it remains within the normal range values for healthy subjects. On the other hand, there is a slight but significant decrease in rectal temperature in bright light in comparison to dim light conditions. The findings showing the decreased rectal temperature with concomitant increase in glucose concentration observed in bright light conditions might be explained by the mechanism involving melatonin action as shown previously by Aizawa and Tokura (1999). |
