Noise-induced sleep disruption increases weight gain and decreases energy metabolism in female rats.

ABSTRACT:

Background/objectives

Inadequate sleep increases obesity and environmental noise contributes to poor sleep. However, women may be more vulnerable to noise and hence more susceptible to sleep disruption-induced weight gain than men. In male rats, exposure to environmental (i.e. ambient) noise disrupts sleep and increases feeding and weight gain. However, the effects of environmental noise on sleep and weight gain in female rats are unknown. Thus, this study was designed to determine whether noise exposure would disturb sleep, increase feeding and weight gain and alter the length of the estrous cycle in female rats.

Subjects/methods

Female rats (12 weeks old) were exposed to noise for 17d (8 h/d during the light period) to determine the effects of noise on weight gain and food
